sequence-based genotyping clarifies conflicting historical morphometric and biological data for 5 eimeria species infecting turkeys.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 important eimeria species infecting turkeys, eimeria meleagrimitis (usmn08-01 strain), eimeria adenoeides (gu ...201525609693
simultaneous identification and dna barcoding of six eimeria species infecting turkeys using pcr primers targeting the mitochondrial cytochrome c oxidase subunit i (mtcoi) locus.species-specific pcr primers targeting the mitochondrial cytochrome c oxidase subunit i (mtcoi) locus were generated that allow for the specific identification of the most common eimeria species infecting turkeys (i.e., eimeria adenoeides, eimeria meleagrimitis, eimeria gallopavonis, eimeria meleagridis, eimeria dispersa, and eimeria innocua). pcr reaction chemistries were optimized with respect to divalent cation (mgcl2) and dntp concentrations, as well as pcr cycling conditions (particularly a ...201525678350
molecular detection of field isolates of turkey eimeria by polymerase chain reaction amplification of the cytochrome c oxidase i gene.oocysts of eimeria spp. were isolated from litter samples obtained from 30 commercial turkey farms. genomic dna was extracted from clean oocysts, and polymerase chain amplification of the species-specific cytochrome c oxidase subunit i (coi) gene was performed for five species of turkey eimeria. the species tested were eimeria adenoeides, eimeria meleagrimitis, eimeria meleagridis, eimeria dispersa, and eimeria gallopavonis. all dna samples were positive for e. meleagrimitis, nine were positive ...201526017345
coccidia of turkey: from isolation, characterisation and comparison to molecular phylogeny and molecular diagnostics.coccidiosis is a disease caused by apicomplexan parasites of the genus eimeria, which has a significant economic impact on poultry production. multiple species infecting the turkey have been described; however, due to the general lack of unambiguous description, their identification and taxonomy is debatable. in this work, a systematic approach was taken to isolate, characterise and compare coccidian species in the turkey. individual species were tracked according to their unique 18s ribosomal d ...201425020103
complete mitochondrial genome sequences from five eimeria species (apicomplexa; coccidia; eimeriidae) infecting domestic turkeys.clinical and subclinical coccidiosis is cosmopolitan and inflicts significant losses to the poultry industry globally. seven named eimeria species are responsible for coccidiosis in turkeys: eimeria dispersa; eimeria meleagrimitis; eimeria gallopavonis; eimeria meleagridis; eimeria adenoeides; eimeria innocua; and, eimeria subrotunda. although attempts have been made to characterize these parasites molecularly at the nuclear 18s rdna and its loci, the maternally-derived and mitotically replicati ...201425034633
the correct date of the original description and availability of the coccidian name eimeria meleagridis tyzzer (apicomplexa: eimeriorina: eimeriidae).the coccidian eimeria meleagridis tyzzer, an apicomplexan parasite of the turkey, was long believed to be innocuous, but recent research suggests that it may be of greater economic importance than previously realised. hitherto, the date of publication of both the name and the original species description has invariably been wrongly cited as 1927, an error first committed by the describer himself and perpetuated ever since. in fact, the name as published in 1927 was a nomen nudum, being unaccompa ...201020401581
diseases of backyard turkeys in the mexican tropics.with the purpose of identifying the causes of disease and death in backyard turkeys, 768 interviews with growers were carried out in communities of the coastal region of oaxaca, mexico. later, a clinical sanitary evaluation was performed on five randomly selected turkeys of different age and sex. the laboratory tests included: necropsy for clinical diagnosis of diseases and for a histopathological examination of tissues with macroscopic lesions to identify microscopic lesions; hemagglutination i ...200819120252
selection for early (precocious) development of eimeria meleagridis in the turkey.a precocious line of eimeria meleagridis was developed by repeated propagation of the parasite in young turkeys and collection of the very first oocysts produced following infection. after 20 generations of selection, the prepatent period was reduced by 4-8 hr. weight gain of poults given this line, from days 0-3 after infection, was significantly greater than that of poults given the parental strain, indicating that selection resulted in a loss of pathogenicity. poults immunized with the precoc ...200717461277
characterization of a strain of eimeria meleagridis from the isolate of eimeria meleagridis tyzzer, 1927 was obtained by harvesting oocysts from the ceca of a turkey from northwest arkansas and a pure line was established by infecting birds with a single oocyst. oocysts were first produced in the ceca of infected birds from 102 to 108 hr after inoculation and were of similar size (mean length x width, 24.9 x 17.0 microm) to those of eimeria adenoeides moore and brown, 1951 and eimeria gallopavonis hawkins, 1952. the line was identified as e. meleagridi ...200617274300
[composition of eimeria in turkeys in bulgaria].studied was the species composition of eimeria in turkeys on a pedigree farm in the territory of the higher institute of zootechnics and veterinary medicine. metrical and morphologic investigations were carried out with more than 1000 sporulated oocysts isolated from parental flocks, turkey poults for fattening, clinically affected poults at various ages, and from experimentally infected poults. on the basis of the results obtained the following species were ascertained: eimeria meleagridis tyzz ...19846730330
