Eimeria acervulina, E. necatrix, E. brunetti and E. tenella were found to be widely distributed in north-east Georgia. 2. Using immunity challenge techniques 17 flocks from 12 to 72 weeks of age showed significantly lower lesion scores for the first three species compared with susceptible control flocks similarly challenged. Only one flock was found to

T lymphocyte roles during Eimeria acervulina and Eimeria tenella infections
Veterinary Immunology and Immunopathology, 1996This study evaluated the effects of selective depletion of T lymphocytes on Eimeria infections in chickens. Cell depletions were initiated in day- or week-old Hyline SC strain chickens using intra-peritoneal injections of monoclonal antibodies to CD4, CD8, or T cell receptor (TCR) alpha/beta.

Eimeria arizonensis Host: Reithrodontomys megalotis (Baird, 1857) Description.—Oocyst wall smooth and 1.2 (±0.13) thick. Sporulated oocysts 18.9–28.8 by 15–23.1, 23.3 (±2.7) by 20.3 (±1.8) and a length:width ratio of 1.2 (±0.1). Sporocysts 8–13.4 by 5.9–9.3, 11.1 (±1.5) by 7.8 (±0.7) and a length:width ratio of 1.4 (±0.1).

Avian Diseases, 2000
Ten poultry farms (broiler breeder pullets, layer pullets, and broilers) in the provinces of Entre Rios and Buenos Aires in Argentina were examined for presence of Eimeria spp. Litter samples obtained from flocks 7-11 wk old were taken to the laboratory for oocyst counting and sporulation, then concentrated for inoculation into coccidia-free chickens ...

Eimeria praecox infection ameliorates effects of Eimeria maxima infection in chickens
Veterinary Parasitology, 2008The effect of Eimeria praecox on concurrent Eimeria maxima infection was studied in susceptible chickens. Clinical signs of coccidiosis were assessed in single E. praecox or E. maxima infections and compared to dual infection with both Eimeria species. Groups infected solely with 10(4)E.

The reproduction of Eimeria flavescens and Eimeria intestinalis in suckling rabbits
Parasitology Research, 2007Suckling rabbits from six litters were orally inoculated at various ages with oocysts of Eimeria flavescens or Eimeria intestinalis. The total number of oocysts in the ceca served to estimate parasite reproduction. The rabbits at 14 and 16 days old remained uninfected, and in 19-day-old animals, low or no oocyst shedding was observed.

Identification and characterization of an Eimeria-conserved protein in Eimeria tenella
Parasitology Research, 2013The precocious lines of Eimeria spp. have unique phenotypes. However, the genetic basis of the precocious phenotype is still poorly understood. The identification of Eimeria genes controlling the precocious phenotype is of immense importance in the fight against coccidiosis.

Characterization and localization of an Eimeria-specific protein in Eimeria maxima
Parasitology Research, 2013A recently completed analysis of Eimeria maxima transcriptome identified a gene with homology to sequences expressed by E. tenella and E. acervulina but lacking homology with other organisms including other apicomplexans. This gene, designated Eimeria-specific protein (ESP), codes for a protein with a predicted molecular weight of 19 kDa.
