induction of protective immunity against eimeria tenella, eimeria necatrix, eimeria maxima and eimeria acervulina infections using multivalent epitope dna vaccines.	avian coccidiosis is mostly caused by mixed infection of several eimeria species under natural conditions and immunity to avian coccidiosis is largely dependent on t-cell immune response. in this study, 14 t-cell epitope fragments from eight antigens of eimeria tenella (e. tenella), eimeria necatrix (e. necatrix), eimeria maxima (e. maxima) and eimeria acervulina (e. acervulina) were ligated with pvax1 producing 14 monovalent dna vaccines, respectively. protective immunity of the monovalent dna ...	2015	25921712
effects of artemisia annua extracts on sporulation of eimeria oocysts.	the present study aimed to compare the effect of different artemisia annua extracts on sporulation rate of mixed oocysts of eimeria acervulina, eimeria necatrix, and eimeria tenella. three types of a. annua extracts including petroleum ether (pe), ethanol 96° (e), and water (w) extracts were prepared. artemisinin, a sesquiterpene lactone endoperoxide derived from the a. annua analysis of each extract was done by high-performance liquid chromatography with ultraviolet detection (hplc-uv). fresh f ...	2015	25700644
seasonal prevalence of gastrointestinal parasites in desi fowl (gallus gallus domesticus) in and around gannavaram, andhra pradesh.	a study was carried out to know the prevalence of gastrointestinal parasites in desi fowl in and nearby villages of gannavaram, andhra pradesh for a period of 1 year. screening of 492 samples comprising faecal samples and gastrointestinal tracts from freshly slaughtered desi birds at local poultry shops and samples from post mortem examinations at ntr college of veterinary science, gannavaram revealed 63.21 % of gastrointestinal parasites. faecal samples were examined by floatation technique usi ...	2016	27605762
cryptic eimeria genotypes are common across the southern but not northern hemisphere.	the phylum apicomplexa includes parasites of medical, zoonotic and veterinary significance. understanding the global distribution and genetic diversity of these protozoa is of fundamental importance for efficient, robust and long-lasting methods of control. eimeria spp. cause intestinal coccidiosis in all major livestock animals and are the most important parasites of domestic chickens in terms of both economic impact and animal welfare. despite having significant negative impacts on the efficie ...	2016	27368611
observation of the excretion pattern of a precocious line of eimeria necatrix and the strengthening of immune homogeneity.	the excretion frequencies of cecal and intestinal droppings of chinese lingnan yellow chickens were observed for 10 consecutive days. the chickens were then orally inoculated with a precocious line of eimeria necatrix, and the oocysts present in the cecal and intestinal droppings were separately collected and monitored using the mcmaster method. the results showed that the excretion frequency of cecal droppings was significantly lower than that of intestinal droppings, and the oocysts of e. neca ...	2016	26921717
anticoccidial effects of artemisia annua ethanolic extract: prevention, simultaneous challenge-medication, and treatment.	the effect of artemisia annua ethanolic extract (ae) as a potential source of herbal anticoccidial activity was investigated on experimental coccidiosis in chicken. one hundred ninety-two one-day-old chicks were divided in to 8 groups (n = 24) including ae prevention group, ae-treated group, simultaneously challenged ae-medicated group, challenged-untreated group (positive control), unchallenged-untreated group (negative control), salinomycine prevention group, salinomycine-treated group, and si ...	2017	28766151
comparative transcriptome analysis of second- and third-generation merozoites of eimeria necatrix.	eimeria is a common genus of apicomplexan parasites that infect diverse vertebrates, most notably poultry, causing serious disease and economic losses. eimeria species have complex life-cycles consisting of three developmental stages. however, the molecular basis of the eimeria reproductive mode switch remains an enigma.	2017	28814335
prevalence of eimeria species in domestic chickens in anhui province, china.	prevalence studies can adequately assist in the design of prophylaxis strategies for disease control. here, the prevalence of eimeria species in chickens was investigated in anhui province, china, from july to september 2016. a total of 171 samples were tested by microscopic examination and molecular methods. the prevalence of coccidiosis in anhui province was found to be 87.75% (150/171). eimeria tenella was the most prevalent species (80.67%, 121/150), and eimeria necatrix, eimeria mitis, eime ...	2017	29114135
