Roles of probiotic microorganisms in digestive physiology are contributed to enhancing animals health and reducing the incidence of gastrointestinal diseases. Banning the use of antibiotics as growth promoters in poultry in many countries has been contributed to the increasing use of probiotics because long-term use of antibiotics causes antibiotic resistance of pathogenic bacteria in poultry a...
At 7 d postinoculation (DPI) with a mixed culture of avian Eimeria species, 21-d-old chicks maintained in batteries and floor pens on a diet containing 0.15% (3 lb/ton) betaine plus 66 ppm (60 g/ton) salinomycin were significantly heavier and had significantly lower feed conversion ratios and mortality than chicks fed diets containing 0.15% betaine or 66 ppm salinomycin alone, or the control di...
Fecal samples from 20 Caucasian tree squirrels, Sciurus anomalus (Gmelin, 1778) Güldenstaedt, 1785, were collected in Turkey during February and March, 2004, and all 20 were infected with a single species of coccidia, Eimeria serbica. Sporulated oocysts are ellipsoidal, 27.5 x 17.5 (21-34 x 15-20) with a length:width ratio (L/W) of 1.6 (1.4-1.8); they lack a micropyle and oocyst residuum, but 0...
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 w...
A coprological survey of enteroparasites in raptors (60 Falconiformes) from Central Mexico is reported. Three samples contained coccidian unsporulated oocysts, one contained Eimeria sp., one contained trematode eggs and one contained capillarid and trematode eggs and Eimeria sp. After sporulation at the laboratory, oocysts from a Falco peregrinus were identified as Caryospora neofalconis. The p...
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 report of this par...
Eimeria spp. are intracellular protozoa that infect intestinal epithelia of most vertebrates, causing coccidiosis. Intestinal intraepithelial lymphocytes (IEL) that reside at the basolateral site of epithelial cells (EC) have immunoregulatory and immunoprotective roles against Eimeria spp. infection. However, it remains unknown how IEL are involved in the regulation of epithelial barrier during...
Coccidiosis, an enteric disease caused by Eimeria species, continues to be a substantial economic burden on the global poultry industry. With increased concerns regarding prophylactic antimicrobials to control coccidiosis alternate methods of preventative control have been developed, yet innovation to strengthen these methods has been limited. Live Eimeria vaccination stimulates immunity from t...
We collected 50 three-toed box turtles (Terrapene carolina triunguis) from 9 counties of Arkansas and 4 counties of Oklahoma, and examined their feces for coccidial parasites. Nine of 24 (38%) turtles from Arkansas and 8 of 26 (31%) from Oklahoma were found to be passing oocysts of Eimeria ornata. This represents two new geographic distributional records for this coccidian. Measurements of indi...
