An increase in the number of isolations of Mycobacterium xenopei from sputum suggested environmental contamination. The organism was recovered from water taps in 61 of 111 pairs of hot and cold water taps in one hospital, 20 of the 74 pairs in another hospital, but from only 3 of 61 pairs of taps in a third hospital and two of 34 pairs in private houses. Scotochromogens were recovered from taps in the first two hospitals only, and M. kansasii was isolated twice from the same tap in the first hospital. No mycobacteria were isolated from pigeon droppings or viscera, nor from patients' tooth brushes, tooth powder or razor debris. The source of contamination is not known.
从痰液中分离出的偶发分枝杆菌数量增加提示存在环境污染。在一家医院的111对冷热水水龙头中，有61对从水龙头中分离出该菌；在另一家医院的74对水龙头中，有20对分离出该菌；但在第三家医院的61对水龙头中，仅有3对分离出该菌，在私人住宅的34对水龙头中，仅有2对分离出该菌。仅在前两家医院的水龙头中分离出了暗产色菌，堪萨斯分枝杆菌在第一家医院的同一个水龙头中被分离出两次。未从鸽粪、内脏、患者的牙刷、牙粉或剃须刀碎屑中分离出分枝杆菌。污染源不明。
