文档介绍：(一)真菌性皮炎(癣)Dermatophytosis(Ringworm)
八、皮肤病
皮肤真皮层的炎症,以丘疹、脱屑、瘙痒为特征。主要由狗小孢子菌、石膏样小孢子菌、须发癣菌感染引起。
接触性感染,人畜共患。
Dermatophytosis is caused by a fungus(真菌) not a worm(蠕虫), and the lesion is not always in the shape of a ring. Since fungi are everywhere in our environment, it is difficult to determine which pets will develop the problem. The fungus that causes Ringworm can be cultured from the hair coats of normal dogs and cats. These pets might be carriers of the disease to other pets along with people.
患部断毛、掉毛或出现圆形脱毛区,皮屑较多。
也有的不脱毛、无皮屑而患部有丘疹、脓疱或脱毛区皮肤隆起、发红、结节化。
症状:
须发癣感染时,患部多在鼻部,位置对称。
患病犬的面部、耳朵、四肢、趾爪和躯干等部位易被感染,病变处被毛脱落,呈圆形或椭圆形,有时呈不规则状。
慢性感染的犬猫病患处皮肤表面伴有鳞屑或呈红斑状隆起,有的结痂,痂下因细菌继发感染而化脓。痂下的皮肤呈蜂巢状,有许多小的渗出孔。
真菌性皮炎患犬的眼周围干性脱毛并逐渐向面部蔓延
患犬的腰背部掉毛、脱屑
This patch(斑点) is typical of the lesion seen in Ringworm. A diagnosis of this disease can not be made based just on the appearance of this lesion because other skin conditions can show similar
Wood’s灯检查:
在暗室里照射病患部位的毛、皮屑或皮肤缺损区,出现荧光为犬小孢子菌感染,而石膏样小孢子感染不易看到荧光,须发癣菌感染则无荧光出现。
