New insights into the transmission biology of urinary schistosomiasis in Zanzibar.

摘要: A better understanding of the transmission biology urinary schistosomiasis in Zanzibar, Tanzania was only possible after development molecular DNA markers for identification Bulinus africanus group snails, potential intermediate hosts Schistosoma haematobium. Hitherto, natural populations B. globosus and nasutus problematic host status distribution either species remained speculative. By recourse to markers, snail maps could be drawn, revealing an allopatric and, more importantly, leading discovery that played no role transmission. Indeed, Unguja area active S. haematobium humans is confined within globosus. This strong relationship may prove useful predicting Zanzibar if schistosome compatibilities persist, other areas nearby, e.g. coastal Kenya. The reviewed, paper reports on ongoing malacological studies Kenya finally closes by posing question whether medical malacology forms essential component associated with mass-scale chemotherapy control programmes.
