Infección ocupacional adquirida de Leishmaniasis cutánea,

Abstract: En éste artículo se reportan dos casos de Leishmaniasis cutánea americana: Una autoinoculación con aguja contaminada durante el manejo de muestras, y una adquirida durante el trabajo de campo sobre biología de aves.

We report two occupationally acquired cases of American cutaneous leishmaniasis (ACL): one accidental laboratory autoinoculation by contaminated needlestick while handling an ACL lesion sample, and one acquired during field studies on bird biology. Polymerase chain reaction (PCR) assays of patient lesions were positive for Leishmania, subgenus Viannia. One isolate was obtained by culture (from patient 2 biopsy samples) and characterized as Leishmania (Viannia) naiffi through an indirect immunofluorescence assay (IFA) with species-specific monoclonal antibodies (mAbs) and by multilocus enzyme electrophoresis (MLEE). Patients were successfully treated with N-methyl-glucamine. These two cases highlight the potential risks of laboratory and field work and the need to comply with strict biosafety procedures in daily routines. The swab collection method, coupled with PCR detection, has greatly improved ACL laboratory diagnosis.

Safe Injection Practices & Bloodborne pathogens training

The One & Only Campaign is a public health campaign, led by the Centers for Disease Control and Prevention (CDC) and the Safe Injection Practices Coalition (SIPC), to raise awareness among patients and healthcare providers about safe injection practices. The campaign aims to eradicate outbreaks resulting from unsafe injection practices.

Meeting report: 15 th Annual Conference of the European BioSafety Association 2012

Almost 300 people participated in the latest annual conference of the European BioSafety Association (EBSA). This year’s EBSA conference, the 15th ofthe series, took place on June 12–13, 2012 in Manchester, UK. It was preceded by eight full-day courses with almost 200 participants in total. 
       The conference consisted of seven sessions with 16 lectures and started with the opening by the President of the society, Patrick Rüdelsheim (Perseus, Belgium), who presented the evolution of biosafety: starting from an intuitive approach followed by an evidence-based to the current performance-based approach. The welcome address by a representative of the host, the University of Manchester, Nalin Thakker, stressed the historical importance of the  location: first railway station, first telephone exchange and now the role of graphene. A video teleconference call by David Heymann on an armchair (literally) tour of the world of biosecurity addressed the historical approach to Ebola virus in Africa, the origin of HIV, certification of small pox eradication in 1980, SARS in 2003, and the consequences of Hepatitis C in Egypt on workers in Saudi Arabia. The conclusion was: laboratory and health workers are at great risk of infection.
This year's annual meeting of the European BioSafety Association, the 15th of the series, took place on June 12–13, 2012 in Manchester, United Kingdom. Dr. Benedictus Verduin (BioRiskManagement, Wageningen, The Netherlands), President of EBSA 2007–2008, reports the proceedings of the meeting in this concise forum article.

Feliz cumpleaños querido blog!

Pasan muchas cosas hoy además de los cambios políticos en México. Pues hoy es 1° de Diciembre, y no lo quiero dejar pasar, porque hoy este blog cumple 5 años!! Wow!! Si alguien nos hubiera dicho que cumpliríamos 5 años, quizá no lo creeríamos. Pero gracias al interés de las personas que leen este blog y que nos envían sus preguntas, es que aprendemos todos, porque si alguna respuesta no se tiene, se busca, se comenta, y se pone en la mesa. Muchas de esas preguntas llegan de personal de laboratorio interesado, por diversas vías. Pero en todos los casos aportan a hacer crecer este blog. Gracias a todos por su apoyo!!
Felicitamos a los químicos hoy también en su día.
Y hoy también es el Día Internacional de la lucha contra el SIDA!
