Biomphalaria alexandrina and Bulinus truncatus are the main vectors of human Bilharziasis in Egypt. The mycotic inhabitants of both control and treated snails were surveyed at 7 and 15 days intervals. The two molluscicides affected more on the mortality of Biomphalaria alexandrina than Bulinus truncatus. The highest population of zoosporic fungi was collected from Biomphalaria alexandrina, the lowest from Bulinus truncatus. Copper sulphate was more effective than Bayluscide on the fungal species of both snails. Achlya, Dictyuchus and Saprolegnia were the common genera while Leptolegnia caudata and Pythium ultimum completely missed from treated snails. The total colonies of zoosporic fungi were lowered after. 15 days of treatment. The two molluscicides inhibited the cell division of both tested snails.
亚历山大双脐螺和截形小泡螺是埃及人类血吸虫病的主要传播媒介。每隔7天和15天对对照蜗牛和处理过的蜗牛的真菌群落进行调查。两种杀螺剂对亚历山大双脐螺死亡率的影响比对截形小泡螺的影响更大。游动孢子真菌数量最多的是从亚历山大双脐螺中采集到的，最少的是从截形小泡螺中采集到的。硫酸铜对两种蜗牛的真菌种类比贝螺杀更有效。绵霉属、网囊霉属和水霉属是常见的属，而处理过的蜗牛中完全没有尾细囊霉和终极腐霉。处理15天后，游动孢子真菌的总菌落数降低。两种杀螺剂抑制了两种受试蜗牛的细胞分裂。
