Chicken as potential contamination source of Campylocacter lari in Iquitos, Peru

Frangos como fonte potencial de contaminação por Campylobacter lari em Iquitos, Peru

Abstracts

In order to know the importance of chicken as natural reservoir of Campylobacter lari in Iquitos, Peru; samples were obtained by cloacal swabs from 200 chickens and immediately placed into a semisolid enrichment medium; these were streaked on modified Skirrow Agar. The organism was isolated from 21 (10.5%) samples, corresponding 58.8% to biovar I and 41.2% to biovar II (Lior scheme). The results provide evidence that chicken appear to be prominent reservoirs of Campylobacter lari in Iquitos.

Com o objetivo de conhecer a importância dos frangos como reservatório natural de Campylobacter lari na cidade de Iquitos, Perú, foram estudadas amostras cloacais obtidas de 200 aves. Cada amostra foi semeada em meio de enriquecimento semi-sólido e no ágar de Skirrow modificado. C. lari foi isolado em 21 (10,5%) amostras. Destes, 58,8% corresponderam ao biotipo I e 41,2% ao biotipo II do esquema de Lior. Os resultados obtidos sugerem que os frangos podem ser um importante reservatório de C. lari em Iquitos, Perú.
