结核菌素检测猴结核病血清抗体的应用

利用结核菌素作为抗原,建立间接ELISA检测方法,对3个实验猴饲养场的402只猴进行检测,其中36只猴经细菌培养确认为结核病猴,366只猴经多次结核菌素检测阴性,确认为健康猴。应用SPSS11.0统计软件绘制出ROC曲线,在阳性结果的cutoff值=0.28时,36只结核病阳性猴中有33只显示阳性结果（91.7%）,366只健康猴中有329只显示阴性结果（89.9%）。用结核菌素作为抗原,进行结核病血清抗体检测的敏感性和特异性分别是91.7%和89.9%。结合结核菌素试验,将有利于对饲养猴群的结核病感染状况进行综合评价。     

“灭蚕蝇1号”防治柞蚕饰腹寄蝇病应用方法再试验

通过对"灭蚕蝇1号"防治柞蚕饰腹寄蝇病应用技术方法的重新试验,结果初步表明,不同时期用药,防效差异显著,其中老眠起2日龄用药效果最高,校正防效为57.9%;不同使用浓度防效差异显著,0.25%质量分数的防效最高,为68.5%;从增加用药次数的试验效果看,4龄期用药,并不能提高防效。生产中使用"灭蚕蝇1号"防治柞蚕饰腹寄蝇病可采用二次用药法,即5龄起蚕2～3d进行第1次喷药,5龄起蚕6～7d进行第2次喷药。     

Generalized amyloidosis in rhesus monkeys

Necropsy materials from 57 cases of generalized amyloidosis in rhesus monkeys were reviewed. Clinically, animals with the disease were characterized by cachexia with muscle wasting, recurrent diarrhea, and arthritis. Gross lesions included hepatomegaly, splenomegaly, chronic/active colitis, fibrous strictures of the cecocolic junction, osteoarthritis, and generalized muscle atrophy. Histologic examination revealed minimal to severe deposits of amyloid in the small intestine (100%), spleen (93%), large intestine (67%), liver (40%), lymph nodes (71%), stomach and/or adrenal gland (32%). More amyloid was deposited in the spleen, liver, and small intestine than in other organs. Shigella sp. were isolated from feces in 23% of the cases and 84% had histologic evidence of colitis. Other findings indicated that 100% of the animals had lung mites, 25% had strictures of the cecocolic junction, and 40% had osteoarthritis. Thirty percent of the cases occurred in animals 10 months to 5 years of age, 10% in ages 6 to 10 years, and 60% in animals greater than 10 years old.     

Yersinia pseudotuberculosis in New World monkeys

It is reported on four cases of pseudotuberculosis in 2 Saimiri sciureus, 1 Callithrix jacchus/penicillata hybrid and 1 S. oedipus. The animals came from two different groups, one being infected with Y. pseudotuberculosis serotype I, the other with Y. pseudotuberculosis serotype II. All cases showed intestinal infection of thermophile Campylobacter. Remarkable were severe haemorrhagic components and the distinct RHS-proliferation, especially in the mesenteric lymphatic nodes.
