本文介绍的是近几年来国外文献报道的蜜蜂的两种新传染病,以引起国内养蜂者的注意。一、粉状鳞片幼虫病——蜜蜂幼虫的传染病。该病由于大批幼虫裂解和死亡而引起群势减弱。在美国和某些欧洲国家发现了这种疾病。病原(Bacllius Pulvifaciens)为革兰氏阳性芽孢杆菌,需氧菌,生长温度为35°～37℃,椭圆形的芽孢,位于菌体中央。在营养琼脂培养基上经过10昼夜形成圆球形的浅褐色和浅橙黄色的菌落。Bac·Pulvifaciens在葡萄糖、甘露醇、海藻糖培养基上产酸,液化明胶,还原硝酸盐为亚硝酸盐,分解干酪素,过氧化氢酶试验为阴性。有病的蜂群是传染源。传染 This article describes two new infectious diseases of bees reported in foreign literature in recent years to attract the attention of domestic beekeepers. First, the pink scales larval disease - bee larvae infectious diseases. The disease caused by the collapse of large numbers of larvae and death caused by weakness. The disease was found in the United States and certain European countries. The pathogen (Bacllius Pulvifaciens) is Gram-positive bacillus, aerobic bacteria, growth temperature 35 ° ~ 37 ℃, oval spores, located in the center of the cell. Globular light brown and light orange-yellow colonies formed on nutrient agar medium for 10 days and nights. Bac · Pulvifaciens acidified in glucose, mannitol and trehalose medium, liquefied gelatin, reduced nitrate as nitrite, casein decomposition, catalase test was negative. Sick bees are the source of infection. infection
