We conducted a survey in broiler farms from Romania to establish prevalence and distribution of Eimeria species using single PCR assay. We found Eimeria spp. in 21 (91%) out of 23 flocks, and in 11 (92%) out of 12 farms. Four species of Eimeria were identified: E. acervulina (21/23; 91%), E. tenella (14/23; 61%), E. maxima (5/23; 22%) and E. praecox (3/23; 13%). Infection with a single species ...
background: coccidian infection in poultry is the most common infection in the world and is the cause of mortality and great economic losses in poultry production. objectives: this study was aimed to determine the frequency and eimeria species diversity in broiler farms of hamadan suburb, iran. methods: a total of 16 broiler farms were randomly selected with different production age in 2012. th...
Intestinal coccidiosis, caused by Eimeria species, is an economically-important disease of poultry production industry worldwide. This study was designed to investigate the prevalence of different Eimeria species in the farmed broilers of Khoy city, West Azarbaijan, North West Iran. A total of 26 broiler farms of different production capacities were arbitrarily selected and examined in 2013. In...

The main goal of current study was to investigate the prevalence of coccidiosis in broiler farms in Hamedan province, western Iran. Chicks and fecal samples were collected in all of the 220 broiler farms in this region. All viscera were examined for gross pathological changes. The mucosa of small intestine and the caeca were examined for the presence and identification of parasitic forms using ...
Coccidiosis is an intestinal disease of chickens of major economic importance to broiler industries worldwide. Species of coccidia found in chickens include Eimeria acervulina, Eimeria brunetti, Eimeria maxima, Eimeria mitis, Eimeria necatrix, Eimeria praecox, and Eimeria tenella. In recent years, polymerase chain reaction (PCR) has been developed to provide accurate and rapid identification of...
Aim: The present study was undertaken to know the Prevalence of chicken coccidiosis in Jammu division in both organized and backyard chickens during the year 2010-11. Materials and Methods: A total of 720 faecal samples were collected from both organized farms and backyard poultry (unorganized) sector of Jammu. Results: The overall prevalence of 39.58% was recorded in the present study and five...
A survey of the prevalence of subclinical coccidiosis in broiler-chickens was conducted in the municipality of Mashhad, Khorasan, Iran. Eighty-four chicken farms were randomly selected; from each farm, five birds per 106th week of age.6th week of age. The farm-level prevalence of subclinical coccidiosis was 38% (95% CI: 48 .47%). Uni- and multi-variable associations were tested between each va ...
Clinical chicken coccidiosis is mostly caused by simultaneous infection of several Eimeria species, and host immunity against Eimeria is species-specific. It is urgent to identify common immunodominant antigen of Eimeria for developing multivalent anticoccidial vaccines. In this study, sporozoite proteins of Eimeria tenella, Eimeria acervulina and Eimeria maxima were analyzed by two-dimensional...
The pathogenesis in chickens of the apicomplexan Eimeria praecox was compared with that of Eimeria acervulina, using intestinal lesions, mucosal integrity, body weight gain (BWG) and the feed conversion ratio (FCR) as criteria. Characteristics of each species were described by combinations of polymerase chain reaction assays and classic parasitological signs. There were considerable overlaps in...
