Une épidémie de listériose, accompagnée de mortinatalité, d'avortements, de signes d'atteinte du système nerveux et de mortalité a été observée dans un troupeau de bovins. L'histopathologie n'a pas révélé de micro-abcès cérébraux typiques, mais l'existence d'une méningite purulente très importante. L'examen bactériologique a permis d'isoler Listeria monocytogenes en culture.
Summary
Bacteriological and mycological examinations (cultural and biochemical characteristics) identified 4 pathogenic organisms as contaminants in 6 out of 7 LEP batch 20 rabies vaccines produced 1990 in Nigeria. Cryptococcus neoformans and Penicillium spp. were isolated from 5 vaccine samples, while one sample additionally also contained Rhizopus and Pseudomonas. One vaccine sample was negative for microbial contaminants. Improper conditions of vaccine production and storage are discussed.
