ISOSPORA SUIS PDF

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). The use of Isospora suis, a sister taxon to T. gondii and the causative agent of piglet coccidiosis, could provide a solution for this. In the present. I. suis were seen within the intestinal epithelium and oocysts were recovered from the and identified a new species of porcine coccidia as Isospora suis [2].

Diagnosis Diagnosis can be made most reliably by identifying the coccidia in histologic sections. It is best attempted on piglets that have been sick two to three days so that oocysts have had time to develop.
