The prevalence of Eimeria in sheep in Australia has not been well described, therefore a quantitative PCR (qPCR) was developed, validated and used to study the prevalence and oocyst concentration in lamb faecal samples at three sampling periods (weaning, post-weaning and pre-slaughter) from eight farms across South Australia, New South Wales, Victoria and Western Australia. A total of 3412 faec...

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...

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...

The impact of coccidiosis outbreaks on the productivity of broiler chicken farms can be substantial, depending on the severity of disease caused by particular species and strains of Eimeria. We examined the genetic diversity of Eimeria species present in commercial broiler farms in relation to their performance level. Four groups of broiler chicken farms in Arkansas (AR) and North Carolina (NC)...

BACKGROUND Chicken is fast becoming the world's most consumed meat. As a consequence poultry health is more important now than ever before, with pathogens of chickens recognised as serious threats to food security. One such threat are Eimeria species parasites, protozoa which can cause the disease coccidiosis. Eimeria can compromise economic poultry production and chicken welfare, and have seri...

The aim of this study was to determine the prevalence of Eimeria leuckarti in worker horses and donkeys of Shahrekord and suburb villages, Iran. Study was done on 52 horses and donkeys in January to 2013 in Shahrekord and suburb villages located in South west of Iran. Out of 52 specimens of fecal samples 4(7.6%) were positive for Eimeria leuckarti. The present study is second ...

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...

The frequency of species of the genus Eimeria in a dairy herd in the municipality of Boa Esperança, Southern region of the State of Minas Gerais was assessed. From 37 females of the Friesian breed aged three to seven months, 259 feces samples were analyzed between May and September 2008. The examinations to quantify oocysts per gram of feces (OPG) and identify Eimeria species were conducted at ...
