Superoxide dismutases in Eimeria tenella
Molecular and Biochemical Parasitology, 1991Unsporulated oocysts of Eimeria tenella have high superoxide dismutase (SOD: superoxide:superoxide oxidoreductase, EC 1.15.1.1.) activity and contain several electrophoretically distinct forms of the enzyme, including two forms of Cu/Zn-containing SOD, two forms of Fe-SOD and two forms of Mn-SOD. SOD activity remains high during 12 h of sporulation but

Robenidine Resistance in Eimeria tenella
The Journal of Parasitology, 1978Robenidine protected chickens against cecal coccidiosis infections initiated by a strain of the parasite that had no previous exposure to drugs. No cross resistance was found with 13 strains resistant to other anticoccidials. A strain of Eimeria tenella that was serially propagated in chickens fed mash containing robenidine became resistant to the ...

Mannitol metabolism in Eimeria tenella
International Journal for Parasitology, 1992Unsporulated oocysts of Eimeria tenella contain large quantities of carbohydrates, namely amylopectin, mannitol and glucose. Analysis of carbohydrate content of sporulating oocysts revealed that mannitol content increased markedly during early stages of sporogony (first 4-6h) but slowly diminished during the next 40h of sporulation.

Monosaccharide Transport by Eimeria tenella Sporozoites
The Journal of Parasitology, 1986Eimeria tenella sporozoites were incubated in the presence of 3 different [14C]-labeled sugars; D-glucose, 2-deoxy-D-glucose and 3-O-methyl-D-glucose. The initial velocity, Vi, of uptake of D-glucose and 2-deoxy-D-glucose was similar, 41 micrograms/10(10) sporozoites/min and 46 micrograms/10(10) sporozoites/min, respectively; whereas that for 3-O ...

Synaptonemal complex karyotype of Eimeria tenella
International Journal for Parasitology, 2005In most organisms, biological variability rests on the behaviour of the chromosomes in the meiotic context. Despite the importance of meiosis, very little is known about the meiotic behaviour of the Eimeria chromosomes. The aim of the present study is to describe the standard synaptonemal complex karyotype from Eimeria tenella oocyst spreads by ...

Embryonic Response to Eimeria tenella Infection
The Journal of Parasitology, 1970The chorioallantoic membranes (CAM) of chicken embryos were infected with Eimeria tenella by inoculation of sporozoites into the allantoic cavity. Embryonic mortality during the hemorrhagic phase of the infection (4th to 8th days postinoculation) was highly dose dependent.

Purification of First-Generation Eimeria tenella Schizonts
The Journal of Parasitology, 1998A rapid and simple method for purifying first-generation Eimeria tenella schizonts was developed with infected chicken cecal tissue. The schizonts were harvested from the tissue by treatment with a mixture of 3 enzymes: hyaluronidase, dispase, and collagenase.

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 tenella: Cecal contraction in infected chickens
Experimental Parasitology, 1983The muscle of ceca from chickens infected with Eimeria tenella had an increased amplitude of contraction when compared to the cecal muscle of uninfected control chickens. The increased amplitude was significant (P less than or equal to 0.05) at 5 days postinoculation (PI) and became nonsignificant at 7 days PI.
