The susceptibility of Bulinus tropicus, B. globosus, Biomphalana pfeifferi, Lymnaea natalensis, and Melanoides tuberculata to Calicophoron microbothrium was examined. Bulinus tropicus had the highest prevalence (65.0%), followed by B. pfeifferi (37.5%), B. globosus (6.8%), and M. tuberculata (5.9%). Lymnaea natalensis was refractory to infection. Bulinus tropicus snails infected with C. microbothrium alone or coinfected with either Schistosoma haematobium or S. mattheei 0, 7, 14, and 21 days after exposure to C. microbothrium produced C. microbothrium cercariae only.
研究了热带小泡螺、球小泡螺、费氏双脐螺、纳塔尔椎实螺和瘤拟黑螺对微小杯殖吸虫的易感性。热带小泡螺的感染率最高（65.0%），其次是费氏双脐螺（37.5%）、球小泡螺（6.8%）和瘤拟黑螺（5.9%）。纳塔尔椎实螺对感染具有抗性。感染微小杯殖吸虫的热带小泡螺，在接触微小杯殖吸虫后0、7、14和21天，单独感染微小杯殖吸虫或同时感染埃及血吸虫或马氏血吸虫，仅产生微小杯殖吸虫尾蚴。
