C. Friedrich et al., DISTRIBUTION, HOST SPECTRUM AND ULTRASTRU CTURE OF THELOHANIA-MUELLERI, PFEIFFER 1895 (MICROSPORIDA), Archiv fur Protistenkunde, 146(2), 1995, pp. 201-205
The microsporidium Thelohania muelleri (PFEIFFER, 1895) has been detec
ted in the amphipods Gammarus roeseli and Gammarus fossarum. These hos
ts were collected in the Austrian countries Steiermark, Burgenland and
Vorarlberg as well as in Croatia. The mean spore sizes differed depen
ding on the host species, geographical origin and between host individ
uals from the same location. An explanation for these features is disc
ussed. A hitherto poorly known stage in the lifecycle, the merogonial
plasmodium with diplokarya, is briefly described.
