泰泽氏病是 - 。种以严重腹泻，脱水和迅速死亡为特征的疾病病原为毛样芽孢杆菌本病发生于很多国家和地区，死亡率高达95％，是养兔业，豚鼠的 - 大威胁。

毛样芽孢杆菌是 - 种细长的革兰氏阴性细菌，在肝细胞，平滑肌和心肌以及上皮细胞浆中呈束状，用高碘酸-schiff氏染色和沃辛-stanyニ氏染色以及姬姆萨，银染色等。分离本菌+分困难，大多数研究者认为该病原在人エ培养基和活培养基上都不能生长。有人报道这种细菌能在小白鼠胚胎细胞上生长，但在笫ニ次继代后即失去对小白鼠的致病能カ。近年来用鸡胚卵黄囊内培养分离本菌获得成功。并且有人在鸡胚卵黄囊继代32次后，在断乳仔兔复制了泰泽氏病，并从病兔肝脏中重新分离到本菌。据认为最初用鸡胚卵黄囊接种分离毛样芽孢杆菌之所以不能成功，是因为有肠道细菌大量生长之故。如在人エ感染的病兔的饮水中加入磺胺喹恶啉，再用鸡胚培养分离毛样芽孢杆菌的成功率就高。肠道细菌容易进入肝脏，这给本菌的分离带来困难。毛样芽孢杆菌只能在细胞浆内进行繁殖此外，本菌能产生芽孢，能运动，并具有多形性芽孢菌的抵抗カ较强，能在土壤底层中保持传染性达 - 。年之久

黑豚鼠泰泽氏病的防治方法

XX In addition to rabbits, a variety of animals such as mice, rats, hamsters, guinea pigs, muskrats, cats, and rhesus monkeys have been found to have a prevalence of Tay's disease. Because pathogens are difficult to isolate and culture, in many cases, Tay's disease is mistaken for mucinous enteritis or other similar diseases. The incidence and mortality of this disease are very high, and the rabbits with 6-12 weeks old have the most incidence, but the rabbits and adult rabbits before weaning can also be infected. Bacillus licheniformis is excreted from the feces of sick rabbits, polluting the surrounding environment, and healthy rabbits can be infected after eating. It invades the mucosal epithelium of the small intestine, cecum and colon. It begins to proliferate slowly, has little tissue damage, and has no clinical symptoms. However, under the influence of stress factors such as overheating, overcrowding and handling, the bacteria can rapidly multiply and cause intestinal tract. Mucosal and deep tissue necrosis. Pathogens enter the liver and other organs through the portal vein, causing serious damage. When sulfa drugs are used to treat other diseases, it may easily cause the disease due to interference with the ecological balance of microorganisms in the gastrointestinal tract.xx
