[Light optical and electron microscopic study of the cystic stages in Sarcocystis fusiformis from the buffalo].
Three different cell types are distinguished in the sarcocysts of Sarcocystis fusiformis from the water buffalo: metrocytes, intermediate cells, and merozoites. The former lines the cyst near the border, the two latter lie more inside forming groups of cells separated from each other by septae. The pattern of metrocyte division giving rise to another metrocyte population has not been observed, still remaining obscure. Merozoites do not divide asexually due to their gamont nature to be realized in the final host only. The intermediate cells divide asexually by endodyogeny giving rise, on the one hand, to another population of intermediate cells, and on the other--to merozoites which divide no longer. Cytophotometrical measurements (G. D. Gaibova, 1987) revealed the amounts of DNA per cell nucleus within 1 and 2 c. This quantity corresponds to the stable DNA content in the most numerous population of merozoites (gamonts), whereas the amount between those higher than 1 c and 2 c may be attributed to the nuclei of metrocytes and intermediate cells, respectively.
