Sažetak
Results of a survey of Cyprinus carpio, carp, in Croatia, Yugoslavia and data from carp reared under controlled laboratory conditions, have provided new information on the enigmatic nature of Rhabdospora thelohani or "rodlet cells". Carp larvae were obtained in the laboratory by artificial at 10 and 60 days of age, serially sectioned and examined for R. thelohani. In 10 day larvae, organisms were never observed. However, 60 day fry had rhabdosporans loosely associated with the afferent branchial arteries and ventral aorta distal to the bulbus arteriosus. More proxiamally, they appeared to aggregate at the periphery of the aorta, become associated with with the endothelium while decreasing in number at the periphery and finally localized primarily inside of the bulb. Results of the survey showed one out of a total of five (20 %) 11 mm carp contained R. thelohani ; the organisms were found associated with the adventita of the ventral aorta but not the bulbar tissue per se. The bulbi of all carp was higher than 30 mm in lenght, from all four fish farms sampled, contained varying numbers of rhabdosporans. These observations suggest a migration of rodlet cells to the bulb and suggest but do not conclusively prove that they are not parasites.
