水霉病致病菌为水霉属和绵霉属中的真菌,繁殖适温13℃—18℃。在越冬期里,水霉病对鳖危害严重,尤其是稚、幼鳖,可造成死亡。特别对刚孵出两个月内的稚鳖,危害最为严重。 一、症状 病菌在鳖的体表、四肢、颈部等处都可繁殖。在鳖的伤口上病菌向外长出灰白色棉毛状菌丝,严重时大量繁殖寄生在整个鳖体表面,并分泌大量蛋白分解酶,致使病鳖焦躁不安,负担沉重,食欲减退或拒食,最终消瘦而死亡。
Water fungus pathogenic bacteria in the genus and genus Mucor genus, reproduction temperature 13 ℃ -18 ℃. Overwintering period, water mold disease turtle serious harm, especially juvenile, young turtle, can cause death. In particular, juvenile soft-shelled turtles that have just been hatched for two months have the worst endangerment. First, the symptoms of bacteria in turtle body surface, limbs, neck and other places can reproduce. In the soft-shelled turtle on the pathogen out of gray-white cotton-like mycelium, severe cases of parasitic mass in the body turtle body surface and secretion of a large number of proteolytic enzymes, resulting in sick turtle restless, heavy burden, loss of appetite or antifeedant, the final weight loss death.
