Eighty-eight fecal samples from 2 species of pika, Ochotona collaris and Ochotona hyperborea, collected in Alaska (N = 53) and Russia (N = 35), respectively, were examined for the presence of coccidia (Apicomplexa: Eimeriidae). Five oocyst morphotypes were observed. In O. collaris, we found Eitmeria calentinei, Eimeria cryptobarretti, and Eimeria klondikensis, whereas in O. hyperborea, we found...

More than 1,180 fecal samples were collected from 253 juvenile and 384 adult Townsend's ground squirrels (Spermophilus townsendii) at the Snake River Birds of Prey Area near Boise, Idaho, from February to June 1992. Oocysts of 7 eimerians were observed. Five are new host records (Eimeria beecheyi, Eimeria bilamellata, Eimeria callospermophili, Eimeria lateralis, and Eimeria morainensis), 2 spec...

Bone serves as a multifunctional organ in avian species, giving structural integrity to the body, aiding locomotion and flight, regulating mineral homeostasis, supplementing calcium for eggshell formation. Furthermore, immune cells originate reside bone marrow, sharing milieu with cells, indicating potential interaction functions. In prevalence of gastrointestinal diseases can alter growth resp...

We used PCR to test various protocols and define a technique for DNA extraction directly from chicken-shed stool samples for the identification of Eimeria species that parasitize birds. It was possible to extract and amplify DNA of seven Eimeria species from field stool samples, using both protocols tested; extractions made with phenol/chloroform protocols gave the best results. The primers wer...

The members of the genus Eimeria infect a wide range of vertebrate hosts, such as swine, cattle, goats, sheep, rabbits, turkeys and chickens. It is now generally accepted that seven Eimeria species are recognised to parasitize the intestinal tract of the domestic fowl (Gallus gallus domesticus). Of all the Eimeria species that infect domestic fowl, Eimeria maxima is the most immunogenic species...

Of 35 tuco-tucos (Ctenomys opimus) collected in Bolivia, South America, 31 (88%) had eimerian oocysts in their feces at the time they were examined. Eighteen (58%) of the 31 infected animals were concurrently infected with 2 or 3 eimerian species. Four species of Eimeria were recovered and are described as new species based on the characteristics of sporulated oocysts. Oocysts of Eimeria granif...
