A guide to laboratory techniques used in the study and diagnosis of avian coccidiosis.
A procedure and simple key is given to enable a provisional identification of five species of Eimeria: colour illustrations of gross lesions will aid the identification. Laboratory methods are
Variation in susceptibility of inbred lines of chickens to seven species of Eimeria.
TLDR
Compared with inbred lines of chickens, there appears to be an inverse relationship between susceptibility to E. tenella and susceptibility to the other species: lines which produced most oocysts of E.Tenella produced least oocyst of the otherspecies and vice-versa.
Genetics of resistance to coccidiosis: response of inbred chicken lines to infection by Eimeria tenella and Eimeria maxima.
TLDR
There was evidence of an association of genes of the major histocompatibility complex genes with mortality, but not with weight loss or oocyst production, and there was no indication of association of resistance to coccidiosis with resistance to Marek's disease.
Presence of Borrelia burgdorferi (Spirochaetales: Spirochaetaceae) in Southern Kettle Moraine State Forest, Wisconsin, and Characterization of Strain W97F51
TLDR
This study documents the existence of an established population of I. scapularis and the presence of B. burgdorferi with a novel strain in southeastern Wisconsin.
Strain variations within Eimeria meleagrimitis from the turkey.
TLDR
The results show that strain variation occurs within the species E. meleagrimitis and extreme caution should be used in identifying species of Eimeria from the turkey by the oocyst characters.
Studies on Eimeria dispersa Tyzzer 1929 in turkeys.
TLDR
Eimeria dispersa was isolated from young, intensively housed turkeys in Britain and showed morphological features in common with those of the original description, and was resistant to challenge with a strain of E. dispera obtained from the United States.
The structure and development of the macrogamete and oocyst of Eimeria acervulina.
The fine structure of the macrogametocyte, macrogamete and the early stages in the formation of the oocyst wall of Eimeria acervulina have been described and compared with other species of Eimeria.
The effect of immunity on the early events in the life-cycle of Eimeria tenella in the caecal mucosa of the chicken.
TLDR
There was a moderate decrease in the number of parasites initially seen in the mucosa of the immune birds, suggesting that some of the effects of immunity are exerted before penetration of the surface enterocytes, but the reduction in the numbers of developing parasites was more marked.
Immunological differences in Eimeria maxima: effect of a mixed immunizing inoculum on heterologous challenge.
TLDR
The results show that although immunological differences exist within E. maxima good protection against many strains of this species may be achieved by initial infection with the hybrid mixture of E.maxima.
Some observations on the sexual differentiation of Eimeria tenella using single sporozoite infections in chicken embryos.
TLDR
The results conclusively demonstrate the bisexual nature of the sporozoite, suggest that sexual differentiation is influenced by environmental factors, and show that true clones of Eimeria can be established from individual sporozoites.
