Demonstration of immunity against isospora suis in swine

Veterinary Parasitology, 1982
Piglets naturally exposed or experimentally infected with Isospora suis oocysts were given challenge doses of oocysts to determine the extent of development of immune resistance. Piglets in both studies shed low numbers of, or no detectable oocysts, following challenge.

Sporogony of Isospora suis Biester, 1934 of Swine

Journal of Parasitology, 1982
Sporogony of Isospora suis of swine is described. Unsporulated oocysts were collected immediately after defecation, mixed in 2.5% potassium dichromate solution, incubated at various temperatures, examined at different time intervals, and classified as to stage of development.

Survival of Isospora suis oocysts under controlled environmental conditions

Veterinary Parasitology, 2008
Isospora suis is a coccidian parasite infecting piglets soon after birth. While the gross epidemiology of I. suis is well known, little knowledge exists on the ecology of the oocysts. To study the development and survival of oocysts of I. suis under controlled laboratory conditions, known numbers of oocysts ( approximately 200 in each of 4 replicates ...

PCR-based differentiation of three porcine Eimeria species and Isospora suis

Veterinary Parasitology, 2001
Isospora suis and Eimeria are frequent coccidian parasites of pigs. The unsporulated oocysts of Eimeria species and of I. suis are difficult to differentiate. Therefore, a species-specific PCR was developed. PCR products were amplified from Eimeria polita, Eimeria porci, and Eimeria scabra using primers from the conserved 18S rRNA regions and were ...

Life cycle of Isospora suis in gnotobiotic and conventionalized piglets

Veterinary Parasitology, 1984
Isospora suis had 3 asexual and 1 sexual intra-intestinal conventional life cycle. The first asexual generation was most prominent at 2 days p.i. (post inoculation) and produced 2-7 merozoites. The second-generation meronts were prevalent at 3-4 days p.i. and produced 2-12 large merozoites. At 4-5 days p.i.

Pathogenicity of Isospora suis in gnotobiotic and conventionalised piglets

Veterinary Record, 1985
Isospora suis is unequivocally a primary pathogen of swine. Inoculation of I suis in conventionalised and germ-free piglets caused a biphasic disease course with marked diarrhoea, villous atrophy and necrosis of the intestinal epithelium at four to six and eight to 10 days after inoculation.

Isospora suis: an experimental model for mammalian intestinal coccidiosis

Parasitology Research, 2005
Piglets experimentally infected with 10,000 oocysts of Isospora suis in three identical trials (n = 50) were examined clinically and coproscopically from 5 to 11 days post-infection (d.p.i.), weighed in weekly intervals until the fourth week of life and compared to age-matched asymptomatic controls (n = 17).

Prevalence of oocysts of Isospora suis and Eimeria spp from sows on farms with and without a history of neonatal coccidiosis

Journal of the American Veterinary Medical Association, 1984
Oocysts of Isospora suis were not found in any of 77 fecal samples from sows on farms with a history of neonatal coccidiosis. Oocysts of Isospora suis were found in 1 of 172 fecal samples from farms without a history of neonatal coccidiosis.

Endogenous Development of the Swine Coccidium, Isospora suis Biester 1934

The Journal of Parasitology, 1980
The endogenous development of Isospora suis Biester 1934 is described in piglets inoculated with 150,000 or 200,000 sporulated oocysts. Endogenous stages developed within villous epithelial cells throughout the small intestine. Two distinct types of meronts were seen in tissue sections.
