An investigation to test the efficiency of chemical closets in treating excreta from typhoid carriers is described. The use of these closets kept a stream, which had in the past frequently contained Salmonella typhi, typhoid free for 24 months. Selenite broth as made in this laboratory, containing a final concentration of 0.8% sodium hydrogen selenite when inoculated with the water sample, was significantly better than commercial selenite brilliant green enrichment broth for the recovery of S. typhi.
本文描述了一项关于测试化学便池处理伤寒带菌者排泄物效率的调查。使用这些便池后，一条过去经常含有伤寒杆菌的溪流在24个月内未检出伤寒杆菌。在本实验室制备的亚硒酸盐肉汤，接种水样时亚硒酸钠终浓度为0.8%，在伤寒杆菌的回收率方面明显优于市售的亚硒酸盐煌绿增菌肉汤。
