The Responses of Different Strains of Eimeria acervulina and Eimeria tenella to Medication

Research in Veterinary Science, 1966
SUMMARY The responses of 3 strains of Eimeria acervulina and 4 strains of Eimeria tenella to a number of compounds were examined and showed that different strains of the same species vary in their drug susceptibility. The drug-antagonist relationship between sulphaquinoxaline and p-amino-benzoic acid in infections with a sulphonamide-resistant ...

Eimeria tenella: Immunogenicity of arrested sporozoites in chickens

Experimental Parasitology, 1985
Groups of chickens were medicated with the anticoccidial drug, decoquinate, and starting 1 day after this medication they were given daily inoculations of either 1 X 10(4) (Experiment 1) or 1 X 10(5) (Experiment 2) oocysts of a decoquinate-sensitive strain of Eimeria tenella.

Flotillin-1 Localization on Sporozoites of Eimeria tenella

Journal of Parasitology, 2007
In an attempt to identify parasite surface components involved in the interaction with the host cell, the present research focuses on the rafts of Eimeria tenella that might be involved in the host cell invasion process. To that end, this study was undertaken to investigate the expression of flotillin-1, which is an important component and marker of ...

Capping of Immune Complexes by Sporozoites of Eimeria tenella

The Journal of Parasitology, 1985
Sporozoites of Eimeria tenella were incubated for 10, 20, or 30 min with parasite-specific monoclonal IgG antibody 3D3II from mice and then rinsed in a Tris-buffered glucose saline solution (TBGS). Some sporozoites were then incubated for 10, 20, or 30 min with ferritin- or colloidal gold-conjugated goat anti-mouse IgG antibody and then fixed in 2.5 ...

Eimeria tenella: Cecal contraction in infected chickens

Experimental Parasitology, 1983
The 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.

Eimeria tenella Infection in Testosterone-Injected Chicks

The Journal of Parasitology, 1973
During the hemorrhagic stages of Eimeria tenella infection, the mean hematocrits of testosterone-injected male and female birds were significantly lower than those of uninfected testosteronetreated chicks but remained significantly greater than those of infected, oil-injected animals.

Inhibition of the respiration of Eimeria tenella by quinolone coccidiostats

Biochemical Pharmacology, 1976
Abstract The protozoan parasite Eimeria tenella respires vigorously during sporulation and excystation. Sporulation is initiated and sustained by the respiratory activities, and cannot take place under anaerobic conditions. Excystation is not necessarily associated with oxygen consumption and seems to be a passive process solely carried out by the ...

Biological characteristics of a precocious line of Eimeria tenella

Parasitology Research
The Eimeria tenella Yulin strain (EtYL), which is sensitive to most anti-coccidial drugs, was isolated in the Yulin area of Guangxi, China. Then, Eimeria tenella Yulin precocious line (pEtYL), a precocious line with a prepatent period of 108 h, was obtained through early selection.

The Effect of Histomonas meleagridis on the Development of Eimeria tenella

The Journal of Parasitology, 1973
Two experimental trials were conducted to determine the effect of H. meleagridis on the development of E. tenella. White Leghorn chicks were inoculated orally with 6,250 E. tenella oocysts and/or rectally with 2.0 ml of a turkey liver lesion homogenate containing H. meleagridis.
