Models. S.spindale is wide spread and causing great damage to livestock industry. Still it is less studied blood-fluke probably because of absence of a suitable laboratory model till recent time. Under an ICMR Project, compatibility of mice, rats, rabbits and guinea-pigs for S.spindale was studied taking parameters like percentage fluke recovery, sex ratio, egg load, viability of eggs. In contrast to earlier findings, guinea-pigs proved best suited for maintaining S.spindale in the laboratory followed by rabbits, mice and rats .
We have been able to develop Schistosoma nasale in the rabbit to adulthood with production of eggs and granuloma in its liver Thus, a good laboratory model has been developed which may be used for studying chemotherapy, immunology and pathology of Schistosoma nasale
Cercarial Identificartion. We demonstrated existence of five mammalian schistosome species at Jabalpur . However, the greatest impediment in epidemiological studies in such cases is the difficulty in identifying schistosome cercariae on morphological grounds alone. On the other hand, animal inoculation is not only time consuming but also expensive and laborious way of cercarial identification. Therefore, we examined various methods for differentiating S.incognitum, S.indicum, S.spindale and O.dattai cercarial species. We are successful in our endeavour as certain simple techniques led to identification of cercarial species with considerable accuracy. Amongst these, mention may be made of a staining technique for furcal rami which proved quite simple and most effective methodology. We may provide consultancy on this subject.
