title: Muscle Sarcocystosis in pheasants and first records of the genus Sarcocystis in Phasianus colchicus Linné, 1758 in Czechoslovakia.
abstract: During examination of 41 pheasants from the vicinity of Jindrichův Hradec (South Bohemia) muscle sarcocystosis was found in 15 birds (i.e., in 36.5%). There were two types of sarcosporidia. Type I was recorded in 3 pheasants and possessed small cystozoites measuring 6 x 2 micrometers. There occurred also stages measuring 3-4 x 2 micrometers corresponding in their morphology to merozoites of the pre-cystic phase of reproduction. Type II was found in 12 birds and possessed large, lancet-shaped cystozoites measuring 16 x 2-3 micrometers. Type II conforms to the description of Sarcocystis sp. by Wenzel et al. (1982), whereas type I seems to represent a new species of sarcosporidia.
