“…E. tenella was grown in chickens as described previously and isolated oocysts were purified and sporulated using standard procedures [8]. All oocysts were stored in 2.5% (w/v) potassium dichromate at 4°C until use.…”

A new viability assay for Cryptosporidium and Eimeria sporozoites is described. It involves the use of both acridine orange and bis-benzimide and is more rapid, easier and less subjective than procedures used previously. The assay has been used to investigate the effects of respiratory inhibitors and pH on the sporozoites of C. parvum, C. muris and E. tenella. Neither cyanide nor azide reduced the viability of C. parvum or E. tenella, whereas they had some effect on C. muris. This latter organism, an intracellular parasite of stomach epithelial cells, also differed from the other two in being able to survive pH 2 for as long as 1 h.

We have examined several taxonomic features of a number of strains of Eimeria from many sources world wide. The strains were isolated on the basis of their small spherical (or sub-spherical) oocysts. From a study of mean oocyst dimensions, electrophoretic variation of enzymes, ability to develop in embryonated eggs, absence of gross lesions in heavily infected chickens, and cross-immunity, all the strains were found to belong to one species. For convenience, the parasites when isolated, were referred to as strains of E. mitis/mivati-type, but after characterization they were clearly found to be E. mitis. In contrast, a laboratory strain of E. mivati supplied to one of us (M.W.S.) was found to be a mixture of E. acervulina and E. mitis. Evidence from these and other studies supports the notion that E. mivati is a nomina dubia.

“…Litter samples were obtained from broiler and breeder farms at 46 separate geographical locations throughout England and Scotland. They were homogenized and the oocysts harvested by the method of Horton-Smith & Long (1959). Sporulated oocysts were given to 2^-week-old Houghton Poultry Research Station Light Sussex chickens housed in negative pressure isolators.…”

The electrophoretic mobility of glucose phosphate isomerase (GPI) had been used to identify Eimeria acervulina, E. praecox and E. mivati in isolates of coccidia from commercial sites in the United Kingdom. Mixtures of two or three species gave separate bands upon electrophoresis and each species could be identified provided that it formed at least 10-20% of the total number of oocytes present in a sample of 8 x 10(6) oocysts. The principal forms of GPI corresponded to the GPI of E. acervulina (H), E. praecox (H) and E. mivati (W) and were found in 38, 34 and 8 isolates respectively of the 46 examined. Three further variants of GPI are described.
