Intestinal absorption of beta-methyl-D-glucoside in rats infected with Eimeria nieschulzi.

Glycylproline absorption in rats infected with Eimeria nieschulzi.

Suppressed rejection of Trichinella spiralis in immunized rats concurrently infected with Eimeria nieschulzi.

This study deals with the effect of Eimeria nieschulzi infection on the host immune response to Trichinella spiralis. Six male Sprague-Dawley rats were inoculated with 10' and six with 10'; sporulated E. nieschulzi oocysts. On days 2, 8, and 16 postinoculation (PI), two rats from each infected group, and their paired uninfected controls, were killed and mucosal scrapings from their small intest...

The immunizing potential of sporulated oocysts of Eimeria nieschulzi exposed to heat and Co-60 gamma-radiation.

Sporulated oocysts of Eimeria nieschulzi Dieben 1924, a rat coccidium, were exposed to radiation, heat, or both in an effort to attenuate the parasite. Moderate levels of each treatment or combination thereof attenuated the parasite, reduced pathogenesis (as judged by oocyst discharge during primary infection), and produced immunity to challenge when the oocysts were subsequently inoculated int...

Development of Eimeria nieschulzi (Coccidia, Apicomplexa) Gamonts and Oocysts in Primary Fetal Rat Cells

The in vitro production of gametocytes and oocysts of the apicomplexan parasite genus Eimeria is still a challenge in coccidiosis research. Until today, an in vitro development of gametocytes or oocysts had only been shown in some Eimeria species. For several mammalian Eimeria species, partial developments could be achieved in different cell types, but a development up to gametocytes or oocysts...

On the status of Eimeria nieschulzi oocysts embedded in resin eleven years ago: a permanent method for preserving coccidian oocysts.

Sporulated oocysts of Eimeria nieschulzi that were fixed and mounted on glass slides in polymerized resin in 1976 are examined. Size, shape, and integrity of oocysts and sporocysts are compared to similar observations we made in 1977 and reported in 1978 (Journal of Parasitology 64: 163-164). Our conclusion is that the methods we reported on in 1978 provide one opportunity to produce permanent ...
