Bulinus (Physopsis) africanus africanus (Krauss) in Tanganyika [PDF]

Nature, 1964
SNAILS of the sub-genus Bulinus (Physopsis) are known to be the principal intermediate hosts of Schistosoma haematobium in East Africa. There are several species present, and of these B.(P.) africanus is represented by B.(P.) africanus ovoideus (Bourguignat) which is widely distributed throughout the area. Mandahl-Barth1 suspected that B.(P.) africanus

Bulinus snails in the Lake Victoria Basin in Kenya: Systematics and their role as hosts for schistosomes.

PLoS Neglected Tropical Diseases, 2023
The planorbid gastropod genus Bulinus consists of 38 species that vary in their ability to vector Schistosoma haematobium (the causative agent of human urogenital schistosomiasis), other Schistosoma species, and non-schistosome trematodes.

Effect Of Permethrin On Survival And Reproduction Of <i>Bulinus globosus</i> Morelet 1868 And <i>Bulinus Truncatus</i> Audouin 1827 [PDF]

, 2008
The effects of permethrin on reproduction and survival of Bulinus globosus and Bulinus Truncatus are reported. Serial dilutons of the chemical were used in 96 h exposure tests on the molluscs, followed by postexposure maintenance in the laboratory for 8 ...

A contribution to the respiratory physiology of three South African freshwater pulmonate snails, Bulinus (Physopsis) Africanus (Krauss), Bulinus (Bulinus) Tropicus (Krauss), and Lymnaea Natalensis Krauss [PDF]

, 1966
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.

THE INTERACTIVE EFFECT OF SOME MOLLUSCICIDES ON THE INTERMEDIATE HOST OF HUMAN BILHARZIASIS AND THEIR ASSOCIATED MYCOFLORA IN THE RIVER NILE, EGYPT. [PDF]

Assiut Veterinary Medical Journal, 1994
The mycotic inhabitants of both control and treated snails were surveyed at the 7th and 15th day interval. The highest number of zoosporic species (16) were collected from control samples.

Shell Permeability and Desiccation Physiology Of the Freshwater Snail Bulinus (Bulinus) Tropicus (Krauss)

Malacologia, 2007
The water permeability rate of the shell wall of Bulinus tropicus (Krauss) was determined with tritiated water to be 1.74 ±1.06 μl water per 24 h. The osmotic pressure of the haemolymph increased three-fold to 300 ± 16 mOsm l−1 after 60 days at 85% r.h. of the air.
