diarrhoea in piglets and monkeys experimentally infected with balantidium coli isolated from human faeces.ten piglets and four monkeys free from balantidium were dosed with human faecal homogenate which contained 1.2 x 10(4)-4.8 x 10(4) b. coli cysts. the infection resulted in severe diarrhoea in piglets 1-6 and hydrocortisone-treated monkeys 1-2, moderate diarrhoea in piglets 7-10 and a subclinical infection in monkeys 3-4. in piglets 1-3 and monkeys 1-2, heavy infection of the intestinal mucosa extended from the terminal ileum to the rectum and the mucosa was severely damaged. in piglets 4-10, inf ...19957861483
the prevalence of intestinal protozoa in wild and domestic pigs.we examined faecal samples from 842 domestic and 91 wild pigs in order to record the prevalence of intestinal protozoa. we used staining of faecal smears by noller-westphal-gönnert method, cultivation in modified les broth and microscopical examination of native preparations using small magnification (for detection of balantidium coli). moreover, the faeces from wild pigs were examined by flotation in sheather's sugar solution for detection of coccidia. we found 8 coccidian species in the wild p ...19948073586
