Abstract

An epidemiologycal survey were carried out using the filter of Visser technique for the diagnosis of first-stage larvae (L1) of gastrointestinal nematodes in faecal samples from 150 dairy calves in Paty do Alferes city, Rio de Janeiro state. Feces were individually collected directly of the rectal flask of 150 calves, with age varying between three and 12 months, coming from 15 rural properties in the municipal district Paty do Alferes-RJ. The following genera of nematodes were identified: Haemonchus spp, Trichostrongylus spp., Cooperia spp., Bunostomum spp., Strongyloides and Oesophagostomum spp. The genera of greater occurrence were Cooperia spp. (54%), Haemonchus spp. (50.6%) and Trichostrongylus spp. (48.7%). Of the total of inspected properties, 86.7% presented positive animals for Haemonchus spp. and Trichostrongylus spp. The genera Bunostomum spp. had presented smaller occurrence, with 12,7% of cases. The genera identified with the highest medium values of first-stage larvae in 15mL of faeces were: Cooperia spp. (812) and Haemonchus spp. (489).
