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...

Subclinical bovine coccidiosis is an economic problem worldwide because they appear normal outwardly, but developmental stages damage the absorptive surface of the intestine and weaken the immune system. Information on the occurrence, diversity and economic losses due to Eimeria infection in cattle is lacking in Al-Baha area. The objective of this work was to study prevalence of subclinical bov...

We used PCR to test various protocols and define a technique for DNA extraction directly from chicken-shed stool samples for the identification of Eimeria species that parasitize birds. It was possible to extract and amplify DNA of seven Eimeria species from field stool samples, using both protocols tested; extractions made with phenol/chloroform protocols gave the best results. The primers wer...

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...

In order to determine the involvement of nitric oxide in the pathogenesis of coccidiosis induced by Eimeria, 30 chickens were challenged with mixed sporulated oocysts of four species of Eimeria (E. acervulina, E. maxima, E. necatrix, and E. tenella) at 26 days of age. There was an increasing of oocyst shedding in the infected birds at 6, 10 and 14 days post-infection. Histopathological examinat...

background: coccidiosis is a serious protozoal disease of poultry. the iden-tification of eimeria species has important implications for diagnosis and con-trol as well as for epidemiology. the molecular characterization of eimeria spe-cies infecting egyptian baladi chickens was investigated. methods: eimeria species oocysts were harvested from intestines of naturally infected egyptian baldi chi...

Information on the occurrence, diversity and economic losses due to Eimeria infection on cattle farms is lacking in Western Iran. The principal aim of this study was to determine the prevalence and diversity of Eimeria species in cattle in Hamedan province, Western Iran. In a cross-sectional study performed from June 2010 to April 2013, 400 faecal samples were collected randomly from animals wi...

Prevalence of Eimeria species parasitizing rabbits (Oryctolagus cuniculus) in Taiwan were investigated. Six Eimeria species, namely: Eimeria media (prevalence, 158/642; 24.6%), Eimeria magna (101/642; 15.7%), Eimeria perforans (58/642; 9.0%), Eimeria coecicola (46/642; 7.2%), Eimeria piriformis (16/642; 2.5%), and Eimeria exigua (9/642; 1.4%) were observed. The overall prevalence of these cocci...

all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
