RESUMO
The Tritrichomonas suis (Gruby and Delafond) that occur in the nasal cavity of domestic pigs. Sus scrofa, was isolated, described and its prevalence studies in healthy swine of different areas of Rio Grande do Sul, Brazil. The parasite protozoa was found in 2 of 208 cultures of nasal washings, representing a prevalence of 0.96 porcent. The morphology study of the live specimens done by phase contrats microscopy, dark field microscopy and by examination of fresh and stained specimens, showed that the T. suis isolated has the same morphological characteristics as the nasal cavity of trichomonads described by othe authors
