A study to determine the secretion of Mycobacterium spp. in milk from indigenous cattle was carried out in pastoral cattle reared in the Southern Highlands to Tanzania. The study was aimed at elucidating the dangers associated with milk-borne zoonoses in a society where milk is normally consumed raw. Out of 805 milk samples, 31 (3.9%) were positive for mycobacteria. There was a preponderance of atypical mycobacteria (87%) whereas only two isolates (6.5%) were confirmed as M. bovis. Atypical mycobacteria included: M. terrae (n = 7), M. fortuitum (n = 2), M. flavescens (n = 13), M. gordonae (n = 1) and M. smegmatis (n = 4). Although the number of M. bovis positive samples was low, the habit of pooling milk may still pose great public health dangers to milk consumers in this part of the world. Moreover, isolation of atypical mycobacteria should also be considered to be a danger to human health in countries such as Tanzania, where the number of people with lowered immunity due to HIV infection is on the increase.
在坦桑尼亚南部高地饲养的牧牛中开展了一项确定本土奶牛乳汁中分枝杆菌属分泌情况的研究。该研究旨在阐明在一个通常饮用生奶的社会中，与奶源性人畜共患病相关的危险。在805份牛奶样本中，31份（3.9%）分枝杆菌检测呈阳性。非典型分枝杆菌占多数（87%），而仅2株分离菌（6.5%）被确认为牛分枝杆菌。非典型分枝杆菌包括：土地分枝杆菌（n = 7）、偶然分枝杆菌（n = 2）、微黄分枝杆菌（n = 13）、戈登分枝杆菌（n = 1）和耻垢分枝杆菌（n = 4）。尽管牛分枝杆菌阳性样本数量较少，但在世界这一地区，牛奶集中存放的习惯仍可能对牛奶消费者构成重大公共卫生危险。此外，在坦桑尼亚等国，因感染艾滋病毒而免疫力低下的人数正在增加，非典型分枝杆菌的分离也应被视为对人类健康的一种危险。
