Abstract

BRUHN, Fábio Raphael Pascoti et al. Occurrences of Eimeria spp. and gastrointestinal nematodes in dairy calves in southern Minas Gerais, Brazil. Rev. Bras. Parasitol. Vet. [online]. 2012, vol.21, n.2, pp. 171-175. ISSN 1984-2961.  http://dx.doi.org/10.1590/S1984-29612012000200019.

The aim of this cross-sectional observational study was to determine the frequency and factors associated with infection by Eimeria spp. and gastrointestinal nematodes in 356 calves on 20 dairy farms located in southern Minas Gerais, Brazil. Ten species of Eimeria spp. were identified, of which E. bovis (37.6%) and E. zuernii (17.9%) were the most frequent. From fecal cultures, four genera of gastrointestinal nematodes were recovered, of which Cooperia spp. (74.6%) and Haemonchus (19.4%) were the most frequent. Variables relating to higher levels of technology used on dairy farms showed a significant association (p < 0.05) with higher OPG and EPG counts, and are discussed in this study.

Keywords : EPG; OPG; fecal cultures; risk factors.
