蜜蜂体内的细菌类群很多,特别是属于肠杆菌种的细菌,在蜜蜂的肠道内是普遍存在的。但这些细菌在一般情况下是不会引起蜜蜂的病害的,这些细菌统称健康蜂的微生物区系。而属于致病的细菌,主要的有引起蜜蜂付伤寒的付伤寒杆菌(Bact·Pa-ratyphi alvei)和引起败血病的败血杆菌(Pseudomonas apisepticus)两种。一、付伤寒付伤寒是成年蜂的急性传染病,多发生于冬末和初春,尤其是在当蜂群越冬条件不良的情况下容易发生。患付伤寒病的蜂群,
Bees have many bacterial groups, especially those belonging to the Enterobacter species, which are ubiquitous in the bee’s gut. However, these bacteria generally do not cause bee disease, these bacteria collectively microbial flora of healthy bees. Belonging to pathogenic bacteria, there are mainly two species of Bact Pa-ratyphi alvei and septicemia-causing Pseudomonas apisepticus, which cause the bees to pay typhoid fever. One, to pay typhoid To pay typhoid is an acute infectious disease of adult bees, occurred in late winter and early spring, especially in the case of overwintering conditions when the bees easily occur. Suffering from typhoid swarms,
