Biocontainment in Gain-of-Function Infectious Disease Research

The discussion of H5N1 influenza virus gain-of-function research has focused chiefly on its risk-to-benefit ratio. Another key component of risk is the level of containment employed. Work is more expensive and less efficient when pursued at biosafety level 4 (BSL-4) than at BSL-3 or at BSL-3 as modified for work with agricultural pathogens (BSL-3-Ag). However, here too a risk-to-benefit ratio analysis is applicable. BSL-4 procedures mandate daily inspection of facilities and equipment, monitoring of personnel for signs and symptoms of disease, and logs of dates and times that personnel, equipment, supplies, and samples enter and exit containment. These measures are not required at BSL-3 or BSL-3-Ag. Given the implications of inadvertent or deliberate release of high-threat pathogens with pandemic potential, it is imperative that the World Health Organization establish strict criteria for biocontainment that can be fairly applied in the developing world, as well as in more economically developed countries.

Rethinking biosafety in research on potential pandemic pathogens

If accidentally released, mammalian-transmissible influenza A/H5N1 viruses could pose a greater threat to public health than possibly any other infectious agent currently under study in laboratories, because of such viruses' likely combination of transmissibility and virulence to humans. We advocate explicit risk-benefit assessments before work on such pathogens is permitted or funded, improvement of biosafety practices and enforcement, and harmonization of criteria for permitting such experiments across government agencies, as well as internationally. Such potential pandemic pathogens, as they have been called, jeopardize not only laboratory workers and their contacts, but also the wider population, who should be involved in assessments of when such risks are acceptable in the service of scientific knowledge that may itself bear major public health benefits.

Trends Relevant to the Biological Weapons Convention

Excerpt

The potential dual use of life sciences knowledge, tools, and techniques reinforces the need for the scientific community to be aware of the norms of responsible and appropriate scientific conduct, as well as international and national legal requirements. Over the past decade, national and international scientific organizations having become increasingly engaged in issues related to the responsibilities of the scientific community to help reduce the risks of misuse of life sciences research (Bowman et al., 2011; IAP, 2005; NRC, 2004, 2006a, 2009a, c, 2011a; OECD, 2004; Royal Society and Wellcome Trust, 2004; WHO, 2005, 2007a). Scientists can also play a useful role in communicating with policy makers and civil society to help them understand the nature, applications, and potential positive and negative implications of developments in their field. Perspectives from the scientific community can contribute to discussions of how to create the best mix of policies and practices to achieve safety and security without unduly hampering global scientific progress for beneficial applications. This is the motivation and foundation for the workshop and the committee's report.

EuroNHID Survey: Capabilities in 48 isolation facilities

BACKGROUND: Highly infectious diseases (HIDs) are defined as being transmissible from person to person, causing life-threatening illnesses and presenting a serious public health hazard. The sampling, handling and transport of specimens from patients with HIDs present specific bio-safety concerns.
FINDINGS: The European Network for HID project aimed to record, in a cross-sectional study, the infection control capabilities of referral centers for HIDs across Europe and assesses the level of achievement to previously published guidelines. In this paper, we report the current diagnostic capabilities and bio-safety measures applied to diagnostic procedures in these referral centers. Overall, 48 isolation facilities in 16 European countries were evaluated. Although 81% of these referral centers are located near a biosafety level 3 laboratory, 11% and 31% of them still performed their microbiological and routine diagnostic analyses, respectively, without bio-safety measures.
CONCLUSIONS: The discrepancies among the referral centers surveyed between the level of practices and the European Network of Infectious Diseases (EUNID) recommendations have multiple reasons of which the interest of the individuals in charge and the investment they put in preparedness to emerging outbreaks. Despite the fact that the less prepared centers can improve by just updating their practice and policies any support to help them to achieve an acceptable level of biosecurity is welcome.

Low-temperature decontamination with hydrogen peroxide or chlorine dioxide for space applications

Abstract:
The currently used microbial decontamination method for spacecraft and components uses dry-heat microbial reduction at temperatures of >110°C for extended periods to prevent the contamination of extraplanetary destinations. This process is effective and reproducible, but it is also long and costly and precludes the use of heat-labile materials. The need for an alternative to dry-heat microbial reduction has been identified by space agencies. Investigations assessing the biological efficacy of two gaseous decontamination technologies, vapor hydrogen peroxide and chlorine dioxide, were undertaken in a 20-m(3) exposure chamber. Five spore-forming Bacillus spp. were exposed on stainless steel coupons to vaporized hydrogen peroxide and chlorine dioxide gas. Exposure for 20 min to vapor hydrogen peroxide resulted in 6- and 5-log reductions in the recovery of Bacillus atrophaeus and Geobacillus stearothermophilus, respectively. However, in comparison, chlorine dioxide required an exposure period of 60 min to reduce both B. atrophaeus and G. stearothermophilus by 5 logs. Of the three other Bacillus spp. tested, Bacillus thuringiensis proved the most resistant to hydrogen peroxide and chlorine dioxide with D values of 175.4 s and 6.6 h, respectively. Both low-temperature decontamination technologies proved effective at reducing the Bacillus spp. tested within the exposure ranges by over 5 logs, with the exception of B. thuringiensis, which was more resistant to both technologies. These results indicate that a review of the indicator organism choice and loading could provide a more appropriate and realistic challenge for the sterilization procedures used in the space industry.

Pulmonary and heart rate responses to wearing N95 filtering facepiece respirators

rkb.us

BACKGROUND: Filtering facepiece respirators are the most common respirator worn by US health care and industrial workers, yet little is known on the physiologic impact of wearing this protective equipment.
METHODS: Twenty young, healthy subjects exercised on a treadmill at a low-moderate (5.6 km/h) work rate while wearing 4 different models of N95 filtering facepiece respirators for 1 hour each, 2 models of which were equipped with exhalation valves, while being monitored for physiologic variables.
RESULTS: Compared with controls, respirator use was associated with mean 1 hour increases in heart rate (range, 5.7-10.6 beats per minute, P < .001), respiratory rate (range, 1.4-2.4 breaths per minute, P < .05), and transcutaneous carbon dioxide (range, 1.7-3.0 mm Hg, P < .001). No significant differences in oxygen saturation between controls and respirators were noted (P > .05).
CONCLUSION: The pulmonary and heart rate responses to wearing a filtering facepiece respirator for 1 hour at a low-moderate work rate are relatively small and should generally be well tolerated by healthy persons.

Establishing a laboratory network of influenza diagnosis in Indonesia

topnews.in

Abstract
Indonesia has been part of the global influenza surveillance since the establishment of a National Influenza Center (NIC) at the National Institute of Health Research and Development (NIHRD) by the Indonesian Ministry of Health in 1975. When the outbreak of avian influenza A (H5N1) occurred, the NIC and US Naval Medical Research Unit 2 were the only diagnostic laboratories equipped for etiology confirmation. The large geographical area of the Republic of Indonesia poses a real challenge to provide prompt and accurate diagnosis nationally. This was the main reason to establish a laboratory network for H5N1 diagnosis in Indonesia. Currently, 44 laboratories have been included in the network capable of performing polymerase chain reaction testing for influenza A. Diagnostic equipment and standard procedures of biosafety and biosecurity of handling specimens have been adopted largely from World Health Organization recommendations.

#Toxoplasmosis no es un virus, es un parásito @quien

wikimedia.org

Cuando leo noticias como que Shakira tiene toxoplasmosis, pues digo, pobre chica, ojalá la atienda un buen infectólogo. Pero cuando el titular de la noticia dice que la toxoplasmosis es un virus, me entra la extrema urgencia de hacer post en el blog y aclarar el asunto. Los virus y los parásitos tienen un mundo de diferencia en sus estructuras, aunque los dos dependen de un huésped. Los virus solo pueden vivir y reproducirse dentro de una célula, a diferencia de los parásitos que tienen sus propias células y ocasionalmente requieren estadios en células u órganos. Además, los virus son extremadamente pequeños en comparación con los parásitos, y genéticamente los parásitos son cientos de veces mas complejos que los virus. En específico, la toxoplasmosis o Toxoplasma gondii ocasiona una enfermedad que puede ser fatal en humanos, y que infecta también a gatos, convirtiéndolos en huéspedes y fuentes de transmisión, aunque la principal fuente de infección son los alimentos mal lavados y el consumo de carne mal cocida. Algunos de los síntomas pueden consultarse en la página de Medline sobre toxoplasmosis. Las hojas de seguridad de microorganismos de Health Canada las pueden ver en: toxoplasmosis.

Guideline for Microbial Risk Assessment

DESCARGAR

Scientists from the Environmental Protection Agency (EPA), U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS) and joined by scientists from other federal agencies developed the Guideline for Microbial Risk Assessment: Pathogenic Microorganisms with Focus on Food and Water (231 pp, 1.24Mb). This document provides a common framework to perform microbial risk assessment (MRA). It lays out a flexible set of approaches, methods, and tools for use to conduct their microbial risk assessment and provide more transparency to the process and results. This guideline addresses issues specific to microbial risk, e.g., secondary transmission, immune status, and growth and die-off of organisms, as well as addressing concepts generic to classical chemical risk assessment.

#WHO guidelines on hand hygiene in health care

Overview. The WHO guidelines on hand hygiene in health care provide health-care workers (HCWs), hospital administrators and health authorities with a thorough review of evidence on hand hygiene in health care and specific recommendations to improve practices and reduce transmission of pathogenic microorganisms to patients and HCWs. The present guidelines are intended to be implemented in any situation in which health care is delivered either to a patient or to a specific group in a population. Therefore, this concept applies to all settings where health care is permanently or occasionally performed, such as home care by birth attendants. Definitions of health-care settings are proposed in Appendix 1.

Recommendations for the Management of #Hepatitis B Virus–Infected Health-Care Providers and Students

The primary goal of this report is to promote patient safety while providing risk management and practice guidance to HBVinfected health-care providers and students, particularly those performing exposure-prone procedures such as certain types of surgery. Because percutaneous injuries sustained by health-care personnel during certain surgical, obstetrical, and dental procedures provide a potential route of HBV transmission to patients as well as providers, this report emphasizes prevention of operator injuries and blood exposures during exposure-prone surgical, obstetrical, and dental procedures.

Antrax en usuarios de heroina

Wikipedia

El ántrax (o carbunco) es una enfermedad infecciosa, aguda y grave producida por el Bacillus antrhacis, y cuya severidad se establece dependiendo de la vía de entrada al individuo afectado. Las esporas han sido utilizadas como armas biológicas. Sin embargo, es un microorganismo que sobrevive en el ambiente, por lo que los animales pueden comer pastura contaminada y enfermarse, o convertirse en reservorios para la diseminación de la bacteria. 

En Junio de 2012 se describieron dos casos de ánthrax en usuarios de heroína en Alemania, y en ese momento se desconocía el origen de la infección. Para el 10 de Julio de 2012, se han descrito 5 casos en total, incluyendo uno en Francia y uno en Dinamarca, y entre los cuales ya se cuenta una muerte. En uno de los casos, no se ha demostrado el consumo de heroína. Se cree que la heroína, prohibida en Europa, fué introducida de contrabando y que en algún momento estuvo en contacto con animales o pastura contaminada. Un caso complicado, ya que en este momento se han emitido boletines de alerta epidemiológica y policiaca, y varios organismos Europeos están en la búsqueda de la fuente para evitar nuevos casos, incluyendo la EUROPOL (European Law Enforcement Agency) y el ECDC (European Centre for Disease Prevention and Control). Una de las recomendaciones es que los usuarios de heroína no la utilicen, una medida que las mismas agencias reconocen será difícil de cumplir. Es posible que si los contrabandistas de heroína siguen almacenando en los mismos sitios, o transportandola en los mismos vehículos, se sigan presentando nuevos casos. Ya se han descrito casos de Anthrax en usuarios de heroína en otros países, como en Escocia.

El conocimiento como factor de vulnerabilidad a la tuberculosis

speakingofresearch.wordpress.com

Resumen: Este estudio buscó identificar la vulnerabilidad a la tuberculosis (TB) relacionada al conocimiento poseído sobre la enfermedad entre 76 alumnos y profesionales de enfermería. Estudio cuantitativo descriptivo, con datos recolectados mediante cuestionario cerrado acerca de la transmisión, formas de prevención y medidas de bioseguridad, diagnóstico y preconceptos sobre la enfermedad. Datos analizados con software SAS versión 9.1.3 con nivel de significatividad de 5% (<0,05). Se evidenció la vulnerabilidad a TB entre alumnos y profesionales relacionada al conocimiento sobre transmisión, formas de prevención, medidas de bioseguridad y diagnóstico. En lo referente a transmisión, se observó mayor vulnerabilidad entre los profesionales. Los resultados determinan necesidad de inversión en tal asunto por parte de instituciones médico-asistenciales, considerando el papel desempeñado por la enfermería en estrategias de prevención y control de la enfermedad.

Medidas preventivas contra el #cólera

El cólera es una enfermedad aguda, diarreica, provocada por la bacteria Vibrio cholerae, la cual se manifiesta como una infección intestinal. Aproximadamente una de cada 20 personas infectadas puede tener la enfermedad en estado grave, caracterizada por diarrea acuosa profusa, vómitos y entumecimiento de las piernas. En estas personas, la pérdida rápida de líquidos corporales lleva a la deshidratación y a la postración. Sin tratamiento adecuado, puede ocurrir la muerte en cuestión de algunas horas. Una persona puede adquirir cólera bebiendo líquido o comiendo alimentos contaminados con la bacteria del cólera. Durante una epidemia, la fuente de contaminación son generalmente las heces de una persona infectada. La enfermedad puede diseminarse rápidamente en áreas con tratamientos inadecuados de agua potable y aguas residuales. La bacteria del cólera también puede vivir en ríos salubres y aguas costeras. Existen varios antibióticos para el tratamiento de la infección incluyendo tetraciclinas (en caso de síntomas, consulte a su médico). Debido a que existen variantes resistentes, el uso de antibióticos es limitado. Hasta el 80% de los casos puede tratarse satisfactoriamente mediante la pronta administración de sales de rehidratación oral (el sobrecito estándar de SRO de la OMS y el UNICEF). El periodo de incubación puede ser desde algunas horas hasta 5 días. Es susceptible a desinfectantes tales como: 2-5% fenol, 1% hipoclorito de sodio, 4% formaldehído, 2% glutaraldehído, 70% etanol, 70% propanol, 2% ácido peracético, 3-6% peróxido de hidrógeno, y 0.16% yoduro de sodio. El cólera puede sobrevivir en el agua de 5- 10 días. El cólera pertenece al grupo de riesgo 2 y se recomiendas medidas de bioseguridad nivel 2 para su manejo, pero con especial enfasis a evitar la pormación de aerosoles durante su manejo.

ABSTRACT
Highly pathogenic avian influenza A/H5N1 virus can cause morbidity and mortality in humans but thus far has not acquired the ability to be transmitted by aerosol or respiratory droplet (“airborne transmission”) between humans. To address the concern that the virus could acquire this ability under natural conditions, we genetically modified A/H5N1 virus by site-directed mutagenesis and subsequent serial passage in ferrets. The genetically modified A/H5N1 virus acquired mutations during passage in ferrets, ultimately becoming airborne transmissible in ferrets. None of the recipient ferrets died after airborne infection with the mutant A/H5N1 viruses. Four amino acid substitutions in the host receptor-binding protein hemagglutinin, and one in the polymerase complex protein basic polymerase 2, were consistently present in airborne-transmitted viruses. The transmissible viruses were sensitive to the antiviral drug oseltamivir and reacted well with antisera raised against H5 influenza vaccine strains. Thus, avian A/H5N1 influenza viruses can acquire the capacity for airborne transmission between mammals without recombination in an intermediate host and therefore constitute a risk for human pandemic influenza.

Las recomendaciones de esta guía de la OMS se basan en una revisión sistemática de la bibliografía consagrada a la relación entre la ventilación y la transmisión de enfermedades, así como a las soluciones de ventilación natural eficaces en el control de las infecciones. Esta guía de la OMS debe usarse junto con otras recomendaciones de interés en el control de las infecciones. 

• Guía Ventilación natural para el control de las infecciones (Español)

This guideline is primarily developed for engineers and architects who design or operate health-care facilities. The guideline is also useful for health-care workers, particularly infection-control professionals who work in health-care facilities. The guideline recognizes that the hospital designers, operators and health-care workers need to work together for effective infection control. This guideline applies to diseases that can be transmitted through fine droplets or through droplet nuclei. The guideline describes how an airborne precaution room and its adjacent areas can be designed to provide natural ventilation control of infections. However, this guideline does not include thorough descriptions for other infection-prevention and control measures.

VIDEO: Aseptic laboratory techniques: plating methods.

Abstract: 
Microorganisms are present on all inanimate surfaces creating ubiquitous sources of possible contamination in the laboratory. Experimental success relies on the ability of a scientist to sterilize work surfaces and equipment as well as prevent contact of sterile instruments and solutions with non-sterile surfaces. Here we present the steps for several plating methods routinely used in the laboratory to isolate, propagate, or enumerate microorganisms such as bacteria and phage. All five methods incorporate aseptic technique, or procedures that maintain the sterility of experimental materials. Procedures described include (1) streak-plating bacterial cultures to isolate single colonies, (2) pour-plating and (3) spread-plating to enumerate viable bacterial colonies, (4) soft agar overlays to isolate phage and enumerate plaques, and (5) replica-plating to transfer cells from one plate to another in an identical spatial pattern. These procedures can be performed at the laboratory bench, provided they involve non-pathogenic strains of microorganisms (Biosafety Level 1, BSL-1). If working with BSL-2 organisms, then these manipulations must take place in a biosafety cabinet. Consult the most current edition of the Biosafety in Microbiological and Biomedical Laboratories (BMBL) as well as Material Safety Data Sheets (MSDS) for Infectious Substances to determine the biohazard classification as well as the safety precautions and containment facilities required for the microorganism in question. Bacterial strains and phage stocks can be obtained from research investigators, companies, and collections maintained by particular organizations such as the American Type Culture Collection (ATCC). It is recommended that non-pathogenic strains be used when learning the various plating methods. By following the procedures described in this protocol, students should be able to: Perform plating procedures without contaminating media. Isolate single bacterial colonies by the streak-plating method. Use pour-plating and spread-plating methods to determine the concentration of bacteria. Perform soft agar overlays when working with phage. Transfer bacterial cells from one plate to another using the replica-plating procedure. Given an experimental task, select the appropriate plating method.

Screening category A and B priority #pathogens

Abstract. One of the objectives of the National Institutes of Allergy and Infectious Diseases (NIAID) Biodefense Program is to identify or develop broad-spectrum antimicrobials for use against bioterrorism pathogens and emerging infectious agents. As a part of that program, our institution has screened the 10 000-compound MyriaScreen Diversity Collection of high-purity druglike compounds against three NIAID category A and one category B priority pathogens in an effort to identify potential compound classes for further drug development. The effective use of a Clinical and Laboratory Standards Institutebased high-throughput screening (HTS) 96-wellbased format allowed for the identification of 49 compounds that had in vitro activity against all four pathogens with minimum inhibitory concentration values of 16 g/mL. Adaptation of the HTS process was necessary to conduct the work in higher-level containment, in this case, biosafety level 3. Examination of chemical scaffolds shared by some of the 49 compounds and assessment of available chemical databases indicates that several may represent broad-spectrum antimicrobials whose activity is based on novel mechanisms of action.

Biorisk Assessment Models (#BioRAMs)

The biorisk assessment models were designed for use by biorisk officers at laboratories and provide visualization of the relative risks, and help to identify risk mitigation measures. These models have incorporated IBTR and international biorisk officer experience in drafting sets of criteria, prioritizing the criteria, and outlining scoring functions for the criteria. The main objective of these models is to help strengthen risk governance in the laboratories by providing assessment methods that are is standardized, systematic, and repeatable. Biorisk subject matter expertise was critical in the development of these models, as there currently is no straight imperial data for laboratory biorisks.

COMIC: Mónica y sus amigos... ¡abajo la #rabia!

Los animales son excelentes compañeros de niños y adultos. Pero a veces, los perros, los gatos y los animales silvestres (murciélagos, mapaches, monos y zorros), así como otros animales, pueden transmitir a la gente una enfermedad muy grave que se llama "rabia".
Si una persona es agredida por un animal, debe lavarse la herida con agua y jabón y acudir al puesto de salud cuanto antes. La rapidez en la búsqueda de ayuda y tratamiento en el puesto de salud es de suma importancia para evitar que la enfermedad se vuelva grave. Una vez que aparecen los síntomas, la rabia no tiene cura.
En las últimas décadas, a pesar de que el número de casos de rabia en las personas disminuyó en muchos de nuestros países, todavía se producen casos, principalmente en niños. Pero hay formas de controlar y hasta eliminar la rabia en las comunidades: vacunando a perros y gatos todos los años y acudiendo al puesto de salud si una persona es agredida por un animal.
La rabia es una enfermedad muy seria, pero con determinación podremos combatirla y así  ayudaremos a crear un ambiente saludable para todos, en nuestra comunidad, en nuestro país y en los otros países de las Américas.
¡Contamos con ustedes!

Biosafety concerns for labs in the developing world

As report reveals lax standards in Asia-Pacific, researchers debate how to enforce rules.

By Ewen Callaway

22 May 2012

Biocontainment labs across the Asia-Pacific region all too often fail to live up to the term. An inspection of dozens of labs has found that nearly one-third of the biosafety hoods intended to protect workers from deadly pathogens did not work properly — an offence for which a Western lab could be shut down. In one facility, only a shower curtain enclosed a table on which the brains of rabid dogs were routinely dissected. Such deficiencies are symptomatic of a biosafety crisis in many of the laboratories that diagnose and study infectious agents in developing countries, say biorisk experts who attended a meeting at London’s Chatham House on 17 May, where the results of the inspection were presented.

VIDEO: The Intersection of Science and Security: a Case Study Approach

Continuing the global dialogue with the scientific and science policy community: focus on Asia and the Western Pacific.

On December 9, 2011 the United States Government sponsored a workshop, The Intersection of Science and Security: a Case Study Approach, Continuing the global dialogue with the scientific and science policy community: focus on Asia and the Western Pacific. The purpose of this workshop was to give attendees a greater understanding of dual use research, including an awareness of strategies for managing dual use research of concern and an appreciation of how these issues are being addressed around the globe. The workshop utilized published articles as case studies, involving Mousepox and a SARS-like virus, as examples of dual use research of concern that highlight issues which investigators, institutions, journal editors, governments, and the scientific and security policy communities need to consider. In addition to presentations of the case studies, there were discussions among all panelists and attendees on global science and security issues as well as those of special interest within Asia and the Western Pacific, including information on training and education resources currently available.

Nos vemos en Oaxtepec, Morelos. #RutaParaLlegar

 Oaxtepec es una población en el municipio de Yautepec en el estado de Morelos, México. El nombre proviene de un vocablo náhuatl "Huax-Tepec"; de "Huaxin": guaje (árbol leguminoso de la familia de las acacias), "Tepetl": cerro y "C": lugar. La interpretación de todo ello, generalmente ha sido aceptada como: "Lugar de los Guajes" o "Cerro de los Guajes". Los cronistas de Indias citaron su nombre como Guaztepeque. Oaxtepec, se encuentra a 10 minutos de Cuautla, Morelos y en Carretera Federal Ciudad de México - Cuautla en el kilómetro 78 o por la carretera estatal libre de Xochimilco.

28 de Abril: Día Mundial de la #Seguridad y la #Salud en el Trabajo en el 2012

El pasado 28 de Abril se celebró el Día Mundial de la Seguridad y la Salud en el Trabajo en 2012 que se centra en la promoción de la seguridad y la salud laboral en una economía verde. El mundo está evolucionando hacia una economía más verde y sostenible. Aunque ciertos trabajos sean considerados como 'verdes', las tecnologías utilizadas pueden proteger el medio ambiente pero no resultar en absoluto seguras.
A medida que la economía verde progresa, es esencial que la seguridad y salud en el trabajo se integre en las políticas de empleos verdes. Esto implica la integración de la evaluación de riesgos y de las medidas de gestión en el análisis del ciclo de vida de todos los empleos verdes.
Un trabajo realmente verde debe integrar la seguridad y la salud en el diseño, el suministro, el funcionamiento, el mantenimiento, las políticas de abastecimiento y reciclaje, los sistemas de certificación y las normas de calidad de seguridad y salud laboral. Esto es especialmente relevante en sectores como la construcción, el reciclaje de residuos, la producción de energía solar y el tratamiento de biomasa.
