ABSTRACT

Enteroviruses especially Coxsackie B viruses [CBVs] are responsible for approximately 50% of viral myocarditis cases. Coxsackie B viruses were inoculated in BGM cells for three successive passages. Viral capsid proteins were screened by SDS-PAGE, followed by Western blot. Electrophoretically separated proteins of CB2, CB4 in comparison to CA9, Echo9, and PV1 Sabin, showed common peptides particularly at the low molecular weight [ranging between 40 to 10 kDa]. The results of immunoblotting analysis using polyclonal antibodies raised against the whole Coxsackieviruses B viral particles did not reflect that all those bands are immunogenic, nevertheless those peptides could be used to raise specific antibodies which in turn could be useful in detecting viral circulating antigens

ABSTRACT

Se detectó un incremento en los casos reportados de meningoencefalitis viral (MEV) en los meses de octubre y noviembre de 1995 con respecto a igual período de 1994. Se recibieron en el Laboratorio de Enterovirus del Instituto de Medicina Tropical "Pedro Kouri" 43 muestras de heces fecales procedentes de niños con este diagnóstico, y se obtuvieron 23 aislamientos (53,4 por ciento) identificados como Coxsackievirus B5. Además, en 43 sueros pareados investigados por la prueba de neutralización frente a varios Enterovirus, se obtuvieron 21 positivos (48,8 por ciento) al agente aislado. Esto nos permitió afirmar, apoyados en el cuadro clínico y en la epidemiología, que estábamos en presencia de un brote de MEV producido por coxsackievirus B5
