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...

The focus of this work is to determine the distribution and identify species of Eimeria parasites of dairy goats in the livestock of the National Goat and Sheep Research Center in Sobral, State of Ceará, Northeast Brazil. Results showed the presence of multiple species in 196 of 215 analyzed samples (91.2%). Fifty five out of these were from kids (28%) and 141 from adult goats (72%). Eight diff...

Coccidiosis is recognized as the major parasitic disease of poultry and is caused by the apicomplexan protozoa Eimeria. Increasing evidence shows the complexity of the host immune response to Eimeria and microarray technology presents a powerful tool for the study of such an intricate biological process. Using an avian macrophage microarray containing 4906 unique gene elements, we identified im...

Raeini breed is the most productive Cashmere goat in Iran. Helminthes infections cause major economiclosses globally to the livestock industries and farming communities. The objective of this study was todetermine the seasonal prevalence and intensity of Eimeria and gastrointestinal helminth parasitic infectionsin Raeini goats in Iran. A total of 438 faecal samples were randomly taken from clin...

Present study was conducted to evaluate the effect of aqueous methanolic extract from Saccharum officinarum on the sporulation and morphology of oocysts of four Eimeria species (Eimeria tenella, E. necatrix, E. mitis, E. brunetti) of poultry. Sporulation inhibition bioassay was used to evaluate the activity of Saccharum officinarum extract (SOE) on the sporulation of coccidian oocysts. In this ...

BACKGROUND Coccidiosis of domestic fowl, caused by species of the Genus Eimeria, is responsible for important economic losses in poultry production. Because different species and/or strains can vary in pathogenicity and other biological parameters, their precise characterization is important for epizootiological studies. METHODS Fifty samples from litter, whole intestinal tract and feces were...

Coccidiosis is one of the biggest challenges faced by the global poultry industry. Recent studies have highlighted the ubiquitous distribution of all Eimeria species which can cause this disease in chickens, but intriguingly revealed a regional divide in genetic diversity and population structure for at least one species, Eimeria tenella. The drivers associated with such distinct geographic var...

The feral Soay sheep (Ovis aries L.) population on Hirta, St Kilda, is host to a diverse component parasite community, but previous parasitological studies of the population have only focussed on the metazoan species. This paper reports the first epidemiological study of the protozoan species comprising Cryptosporidium parvum, Giardia duodenalis and 11 species of Eimeria in Soay sheep across 3 ...
