The role of Isospora suis in the ethiology of diarrhoea in suckling piglets

Parasitology Research, 2003
Various studies have confirmed the notable spread of Isospora suis in Italy but the role of the primary pathogen in enteric diseases during the neonatal period remained unclear . In this study, wide ranging investigations (parasitology, bacteriology, virology) were carried out on 21 pools of faeces from suckling piglets with diarrhoea and 18 control ...

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).

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 ...

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 ...

Cystoisospora suis Control in Europe Is Not Always Effective

Frontiers in Veterinary Science, 2020
After introduction of the anticoccidial toltrazuril for the metaphylactic treatment of suckling piglet coccidiosis, only few field evaluations on the effect of treatment against the causative agent, Cystoisospora suis, were performed.

Motility of Isospora suis Meronts

The Journal of Parasitology, 1983
The endogenous asexual stages of Isospora suis in piglets consist of two distinct types of meronts, both of which are elongate and retain their sporozoite-shape during merogony (Lindsay et al., 1980, J. Parasitol. 66: 771-779). Sporozoiteshaped, Type I meronts are binucleate, whereas, sporozoite-shaped, Type II meronts are multinucleate.

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.

Ultrastructure of developing Isospora suis in cultured cells

American Journal of Veterinary Research, 1991
SUMMARY The ultrastructure of Isospora suis sporozoites, type-1 meronts, and type-1 merozoites was examined, using transmission electron microscopy of infected cultured cells. The ultrastructure of sporozoites and type-1 merozoites was similar.
