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 To determine the prevalence and diversity of Eimeria spp. in dairy cattle present in and around Guwahati, Kamrup district, Assam, India. MATERIALS AND METHODS A total of 2339 fecal samples of calves (535), heifer (641) and adult (1163) cattle were screened for 1 year present in and around Guwahati, Assam for detection of Eimeria oocysts by flotation techniques. Sporulation of the oocyst w...

Partial plastid 23S and nuclear 18S rDNA genes were amplified and sequenced from 2 morphologically similar Eimeria species. E. antrozoi from a bat (Antrozous pallidus) and E. arizonensis from deer mice (Peromyscus spp.), as well as some other Eimeria species from bats and rodents. The phylogenetic trees clearly separated E. antrozoi from E. arizonensis. The phylogenies based on plastid 23S rDNA...

Eimeria species are frequently found in water buffalo (Bubalus bubalis) in Brazil. Here, we report those Eimeria spp. that infect buffalos during their first year of life. Fresh fecal samples were examined from 2 groups (1 group/yr for 2 yr, 2000-2002), each with 18 water buffalo calves (both sexes), from birth through 12 mo of age, in Selvíria, MS, Brazil. Five oocyst morphotypes were observed...

This investigation was carried out to determine the prevalence of Eimeria infections and the diversity of Eimeria species in camels of Tabriz region. The prevalence of Eimeria spp. infection and the intensity of faecal oocysts were determined in 164 camels using floatation and sporulation techniques. Faeces of 34 camels (20.73%) were infected with four Eimeria species including E. bactriani (52...

A cross-sectional study was carried out to determine the prevalence, species characterization and associated risk factors with Eimeria (E.) in sheep of district Toba Tek Singh from April, 2009 to March, 2010. Of the total 486 faecal samples examined for Eimeria, 209 (43%) were found infected with five species of Eimeria. Amongst the identified species of Eimeria, E. ovinoidalis was the commones...

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...

During the summers of 2000, 2001, and 2002, 1,950 fecal samples from 4 families, 10 genera, and 16 species of rodents in Alaska, U.S.A. (N1⁄41,711), and Siberia, Russia (N1⁄4239) were examined for coccidia (Apicomplexa: Eimeriidae). The 4 families sampled were Dipodidae (jumping mice), Erethizontidae (New World porcupines), Muridae (mice, rats), and Cricetidae (voles, lemmings). Nineteen oocyst...

Unlike with Eimeria species infecting chickens, specific identification and nomenclature of Eimeria species infecting turkeys is complicated, and in the absence of molecular data, imprecise. In an attempt to reconcile contradictory data reported on oocyst morphometrics and biological descriptions of various Eimeria species infecting turkey, we established single oocyst derived lines of 5 import...

AIM The aim of this study was to determine the prevalence of gastrointestinal (GI) parasitic infections in goats of hilly region of Meghalaya. MATERIALS AND METHODS A total of 834 fecal samples of goats were screened for 1 year (2014-2015) using flotation techniques. RESULTS The overall prevalence of GI parasitic infections in goats was 28.65%. Season-wise highest infections were recorded d...
