Biomphalaria pfeifferi (Krauss, 1848)[1] | |
Biomphalaria pfeifferi is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.
This snail is a medically important pest,[2] because of transferring the disease schistosomiasis.
Distribution
Biomphalaria pfeifferi is an African species. It has recently expanded its native range.[2]
Distribution of Biomphalaria pfeifferi include:
The type locality is Umgani-Valley, Natal, South Africa[1] (in the times of the description it was the British Colony of Natal).

Parasites
Parasites of Biomphalaria pfeifferi include the following 11 species found in Tanzania:[6]
- Schistosoma mansoni[6][7]
- undescribed clinostomatid[6]
- two species undescribed strigea[6]
- Cercaria porteri[6]
- Cercaria blukwa[6]
- two species of undescribed echinostome[6]
- Cercaria lileta[6]

Toxicology
The seeds of the tree Balanites aegyptiaca have a molluscicide effect on Biomphalaria pfeifferi.[8]
Substance | Route | LC50 | Reference |
---|---|---|---|
Powder of crude kernels of Balanites aegyptiaca | immersion(?) | 60 ppm | [8] |
Acetone extract of powder of the kernels of Balanites aegyptiaca | immersion(?) | 172,40 ppm | [8] |
Ethanol extract of the powder of kernels of Balanites aegyptiaca | immersion(?) | 84,15 ppm | [8] |
Ethanolic extract of the fruits of Dalbergia sissoo (family Leguminosae) exhibited molluscicidal effect against eggs of Biomphalaria pfeifferi.[9]
