Histological and histochemical studies on the digestive gland of Bulinus truncatus infected with Schistosoma haematobium.

Abstract: The structure of the uninfected and infected digestive gland of the fresh-water snail, Bulinus truncatus, was studied histologically and histochemically. The digestive gland consists of two types of cells: digestive and secretory cells clearly differentiated from each other. The pathological effects of infection of the snail with cercariae of Schistosoma haematobium have resulted in considerable structural and histochemical alterations in the digestive gland. Generally, the main effects were reflected by increased cellular vacuolation and marked diminution of carbohydrates, proteins and lipids of the gland cells.

The diversity of fresh water snail fauna in Kiri dam, Adamawa State, North Eastern Nigeria

Abstract: Freshwater Snails are crucial in assessing the ecological status of water bodies, besides their economic, public and veterinary health importance. Hence, the need to study the occurrence, and diversity of freshwater snails in Kiri dam where there is paucity of such information becomes imperative. Accordingly, this study was carried out between December, 2016 and July, 2018. Snails were searched for in the five contact sites identified using long handle metal scoop nets in accordance with standard procedure. Snails recovered were examined for natural infections. Eleven (11) different fresh water snail species were encountered including Bulinus globosus, Bulinus truncatus, Biomphalaria pfeifferi, Lymnaea natalensis, Lanistes ovum, Lanistes varicus, Pila ovata, Melanoides maculata, Melanoides tuberculata, Bellamya unicolor and Gabiella tchadiensis of the eleven different snail species examined, only Bulinus globosus Bulinus truncatus and Biomphalaria pfeifferi shed schistosome cercariae. The other 8 species did not have any natural infections. The study revealed that Kiri Dam harbours diverse species of fresh water snails including those of public health importance. The presence of naturally infected snails indicates that the people engaging in various activities in the dam, are predisposed to infections harboured by these snails.

Studies on the biology of bulinus truncatus under laboratory conditions

Abstract: A two-year laboratory study on the biology (including self-fertilization) of Bulinus truncatus, the intermediate host of Schistosoma haematobium, S. bovis and Paramphistomum microbotrium in Iran, has revealed information on the longevity, reproduction, hatchability rate, hatching time during various months of the year, and growth and mortality rates of this snail. It was found that the reproduction, hatchability and growth rate of Bulinus truncatus increase under condition of self-fertilization.
