Molecular Characterization of Eimeria Species Naturally Infecting Egyptian Baldi Chickens
BACKGROUND Coccidiosis is a serious protozoal disease of poultry. The identification of Eimeria species has important implications for diagnosis and control as well as for epidemiology. The molecular characterization of Eimeria species infecting Egyptian baladi chickens was investigated. METHODS Eimeria species oocysts were harvested from intestines of naturally infected Egyptian baldi chicke...
متن کاملEimeria-Stimulated Intestinal IELs in Chickens
Intraepithelial lymphocytes (IELs) play a critical role in protective immune response to intestinal pathogens such as Eimeria, the etiologic agent of avian coccidiosis. A list of genes expressed by intestinal IELs of Eimeria-infected chickens was compiled using the expressed sequence tag (EST) strategy. The 14,409 ESTs consisted of 1851 clusters and 7595 singletons, which revealed 9446 unique g...
متن کاملPathogenesis of Eimeria praecox in chickens: virulence of field strains compared with laboratory strains of E. praecox and Eimeria acervulina.
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...
متن کاملMolecular Identification of Eimeria Species in Broiler Chickens in Trinidad, West Indies
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...
متن کاملPrevalence and molecular characterisation of Eimeria species in Ethiopian village chickens
BACKGROUND Coccidiosis, caused by species of the apicomplexan parasite Eimeria, is a major disease of chickens. Eimeria species are present world-wide, and are ubiquitous under intensive farming methods. However, prevalence of Eimeria species is not uniform across production systems. In developing countries such as Ethiopia, a high proportion of chicken production occurs on rural smallholdings ...
