We determined the prevalence of tuberculosis and brucellosis reactors in the dairy herds in the Mbarara district of Uganda in 2002. This is one of the most important dairy-production areas of the country and includes both pastoral and agro-pastoral zones. A total of 340 (of 11,995) randomly selected herds were tested for tuberculosis, using the intradermal tuberculosis-skin test and 315 (of 10,562) herds tested for brucellosis using the serum Rose Bengal test. The herd prevalence for tuberculosis reactors was 74.1% (95% confidence intervals 69, 78), the individual-animal prevalence was of 6.0% (5.6, 6.5) and within-herd range was 1-50% (up to 100% if suspicious reactors were included). The herd prevalence for brucellosis was 55.6% (50, 61.2) individual-animal prevalence 15.8% (14.8, 16.7) and within-herd range 1-90%. The reactor prevalence increased with the age of the animals for both tuberculosis and brucellosis. Tuberculosis reactor prevalences were higher in animals from the agro-pastoral zone. However, the individual-animal and herd prevalences of brucellosis seroprevalences were higher in the pastoral zone.
2002年，我们测定了乌干达姆巴拉拉区奶牛群中结核病和布鲁氏菌病反应动物的流行情况。该地区是该国最重要的奶牛生产区之一，包括牧区和农牧混合区。总共从11995个牛群中随机选取340个进行结核菌素皮内试验以检测结核病，从10562个牛群中选取315个进行血清虎红试验以检测布鲁氏菌病。结核病反应牛群的流行率为74.1%（95%置信区间69, 78），个体动物流行率为6.0%（5.6, 6.5），牛群内范围为1 - 50%（若包括可疑反应动物则高达100%）。布鲁氏菌病反应牛群的流行率为55.6%（50, 61.2），个体动物流行率为15.8%（14.8, 16.7），牛群内范围为1 - 90%。结核病和布鲁氏菌病的反应动物流行率均随动物年龄增长而升高。农牧混合区动物的结核病反应动物流行率更高。然而，牧区布鲁氏菌病血清流行率的个体动物和牛群流行率更高。
