Bacillus thuringiensis israelensis produce crystal proteins which can be converted into toxins in the gut of the mosquito larva . the toxins act on larvae of limited species including mosquitoes , blackflies and non - biting midges 苏云金杆菌会产生蛋白质结晶体，而结晶体在蚊子幼虫的肠内化为毒素，这些毒素会令某些品种包括蚊子墨蚋不叮不咬的蠓的幼虫中毒。

Various kinds of crystals were detected from urinalysis including calcium oxalate , amorphous phosphate , triple phosphate and uric acid in 83 patients ( 37 . 9 % ) of the urinary calculus group and 13 patients ( 12 . 6 % ) of the non - calculus group 同时，我们发现在83位（ 37 . 9 % ）尿路结石病患及13位（ 12 . 6 % ）非结石病患的尿液中存在著各类结晶体，包括草酸钙、无定形性磷酸盐、三重磷酸盐及尿酸结晶体等。
