Global production of chickens has trebled in the past two decades and they are now the most important source of dietary animal protein worldwide. Chickens are subject to many infectious diseases that reduce their performance and productivity. Coccidiosis, caused by apicomplexan protozoa of the genus Eimeria, is one of the most important poultry diseases. Understanding the biology of Eimeria par...

The intracellular life-cycle of Eimeria are located in the host cell within a membrane-bound parasitophorous vacuole. The invasion process and the formation of the parasitophorous vacuole are mediated by characteristic organelles within the apical complex. During invasion, the parasitophorous-vacuole membrane is manipulated by the parasite and functions later in the development cycle as a molec...

NK-lysin is an antimicrobial and antitumor polypeptide that is considered to play an important role in innate immunity. Chicken NK-lysin is a member of the saposin-like protein family and exhibits potent antitumor cell activity. To evaluate the antimicrobial properties of chicken NK-lysin, we examined its ability to reduce the viability of various bacterial strains and two species of Eimeria pa...

In this study, the association between Eimeria spp. related signs and innate immune response in dairy calves was examined. Calves (n=100) aged 15-60 days were clinically examined and faecal samples, blood samples and deep nasopharyngeal swabs obtained. The samples were analysed for intestinal pathogens, acute phase proteins and WBC count, and respiratory tract pathogens, respectively. Diarrhoea...

Parasitological examination of faeces of 26 snakes kept in Bio-Ken Snake Farm, Watamu, Kenya revealed new species of Eimeria Schneider, 1875 in Telescopus semiannulatus Smith, 1849. Oocysts of Eimeria arabukosokokensis sp. n. are cylindrical 26.8 (25-29) x 15.1 (14-16) microm with smooth, bilayered oocyst wall and a single polar granule. The broadly ellipsoidal sporocysts average 9.3 (8.5-10) x...

Fecal samples from 12 Pipistrellus kuhlii captured at Shagrah, Saudi Arabia, were examined for coccidia and three (25%) found to harbor a undescribed eimerian, herein described as Eimeria pipistrellus n. sp. Sporulated oocysts were subspherical, 24.8 x 23.2 (22-27 x 20-25) microns, with a bilayered and smooth wall. The micropyle was absent, but a large oocyst residuum and a single polar granule...

The purpose of this study was to determine if the probiotic bacterium, Lactobacillus rhamnosus, generates compounds that affect the sporulation of the oocysts of three species of Eimeria using an in vitro assay. In addition, anticoccidial effects of L. rhamnosus cell-free supernatant (CFS)-based diets were evaluated in chickens following experimental infection with Eimeria tenella and the antic...

The purpose of this study was to evaluate the changes in the serum concentrations of haptoglobin (Hp), serum amyloid A (SAA) and IgG, IgA in calves with diarrhea caused by rotavirus, coronavirus, Escherichia coli F5 and Eimeria species. The experiment was carried out on 40 diarrhoeic and 10 non-diarrhoeic calves (group C). A total of 13 calves were infected with rotavirus or coronavirus (group ...

The coccidia (protistan phylum Apicomplexa Levine, 1970) comprise a large group of obligate intracellular parasites commonly found in all classes of vertebrate hosts and in some invertebrates. This review focuses on those species within the Eimeriidae because they are among the most prevalent and speciose of all parasite groups, and there is no taxonomic summation currently available for those ...
