Survival of Isospora suis oocysts under controlled environmental conditions
Veterinary Parasitology, 2008Isospora 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 ...

Pathogenicity of Isospora suis in gnotobiotic and conventionalised piglets
Veterinary Record, 1985Isospora 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.

Life cycle of Isospora suis in gnotobiotic and conventionalized piglets
Veterinary Parasitology, 1984Isospora 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.

Occurrence of Isospora suis in Germany, Switzerland and Austria
Journal of Veterinary Medicine, Series B, 2005SummaryNationwide surveys for the occurrence of Isospora suis were carried out in Germany, Austria and Switzerland including a questionnaire regarding herd size, health status and management practices and a coccidiosis sampling kit for pooled faecal samples from litters of suckling piglets. A total of 184 veterinary practices participated in the survey

Control of Isospora suis-induced coccidiosis on a swine farm
American Journal of Veterinary Research, 1985SUMMARY Results of a program designed to control neonatal porcine coccidiosis on a total confinement, farrow-to-finish swine farm are reported. The control program consisted of washing, phenol disinfection, and steam cleaning of farrowing houses and treatment of sows with amprolium HCl before and after farrowing.

Endogenous Development of the Swine Coccidium, Isospora suis Biester 1934
The Journal of Parasitology, 1980The 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.

The sporulation time of isospora suis oocysts from different sources
Veterinary Parasitology, 1986Feces containing Isospora suis oocysts were collected from naturally- and experimentally-infected pigs from four different areas of the United States. The unsporulated oocysts were cleaned, concentrated, mixed with 2.5% aqueous potassium dichromate solution, poured into petri dishes to a depth of 5 mm, and incubated at 25 degrees C.

Coccidiosis in swine: a search for extraintestinal stages of Isospora suis
Veterinary Record, 1982Clinical coccidiosis in swine is associated with Isospora suis infection of piglets. The endogenous life cycle of I suis in piglets occurs within the superficial epithelium of the small intestine. Extraintestinal stages of I suis were not demonstrated in tissues of experimentally infected piglets or mice.

PCR-based differentiation of three porcine Eimeria species and Isospora suis
Veterinary Parasitology, 2001Isospora 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 ...

Porcine Coccidiosis – Investigations on the Cellular Immune Response against Isospora suis
Parasitology Research, 2009Porcine neonatal coccidiosis is caused by the protozoan Isospora suis and affects mainly piglets in the first three weeks of life. High morbidity with diarrhoea and reduced weight gain lead to economic losses, affecting pig-breeding worldwide. Infection causes damage of the mucosal surface in the jejunum and ileum and transient non-haemorrhagic ...
