Parasitismo gastrointestinal en un bioterio canino en venezuela

the sección de caninos, felinos y batracios from the facultad de ciencias veterinarias at universidad central de venezuela (ucv) has an important role in teaching and research in the institution. gastrointestinal parasitism is one of the mayor diseases in canines; therefore, integral control measurements to prevent parasitism must be considered epidemiological knowledge of these parasites. in order to get data about the prevalence and parasites genera present in this population, the examination of 64 dogs of mixed breeds including both genders older than 1 year, was carried out. a total of 141 fecal samples were monthly collected, early in the morning from every cage during 5 months. samples were processed using both mc master and baerman techniques. the general average prevalence of gastrointestinal parasitism was 58.10%, being between 38.88% and 65.62% monthly. the mean prevalence and ranks according to genera were: nematoda ancylostoma spp=56.59% (33.33-65.62%), strongyloides stercolaris=11.80% (0-25%) and toxocara spp=3.80% (0-11%). in addition, other classes of parasites were observed: protozoan (coccidian) oocyst cystoisospora (isospora)=19.82% (2-17%). there were only differences in the prevalenceof s. stercolaris by month (p<0.05), may be as a consequence of a higher ambient humidity during november and december. there were no differences in the prevalence of parasitism according to the gender of the host.
