First record of the freshwater snail bulinus beccari (paladilhe 1872) the intermediate host of the parasite schistosoma haematobium in ha’il province Saudi Arabia

Several studies mentioned the genus Bulinus in Saudi Arabia and the Arabian Peninsula such as (Brown & Wright, 1980; Brown, & Gallagher, 1985; Neubert, 1998; Bin Dajem 2009). Most of these studies where in the western and the south regions of the Arabian Peninsula. The genus is medically important because several species of Bulinus function as intermediate hosts for the schistosomiasis blood fluke. Recently a study made by Jamjoom &, Banaja 2007 mentioned that intestinal schistosomiasis is prevalent in Ha’il, without recording any of the genus Bulinus in Ha’il. Bulinus beccari is a freshwater snail and serves as an intermediate host for Schistosoma haematobium, this species is distributed throughout the south-western region of the Arabian Peninsula (Brown & Wright 1980). The present study records B. beccari in the dams of Ha’il province for the first time, and adds additional record to the localities of B. beccari in Saudi Arabia.
