- Description
- From Introduction: The use of chemical molluscicides in the control of schistosome transmitting snails has been largely based on empirical studies of toxicity, rather than on a clear understanding of basic physiology and biochemistry of snail hosts. It is therefore possible that purely physiological studies may in themselves provide information which could be of value in the development of more effective mollucicides. In this investigation an attempt has been made to understand some aspects of the respiratory physiology of three species of fresh-water pulmonate snails, all of which are of medical and veterinary importance in the Republic of South Africa. Bulinus (Physopsis) africanus (Krauss) is the intermediate host of Schistosoma haematobium, the causative organism of human schistosomiasis (Bilharziasis). Bulinus (Bulinus) tropicus (Krauss) is the intermediate host of the conical flukes Calicophoron calicophorum and Paramphistomum microbothrium and of the liver fluke Fasciola hepatica, while Lymnaea natalensis Krauss is the intermediate host of the liver fluke Fasciola gigantica.
