Analysis of mycobacterium in sewage from two tuberculosis prevention and control hospitals in Tianjin in 2019
Objective To understand the sdutus of mycobacteria contamination in the sewage of tuberculosis hospitals,and to provide a reference for the sewage treatment of tuberculosis hospitals.Methods In 2019,the sewage samples from a hospital and a tuberculosis prevention and control center in Tianjin were collected for mycobacterial culture,and the suspected mycobacterial colonies were identified by gene chip method.Results After sewage treatment in a hospital,no water-like non-tuberculous mycobacteria(NTM)and mycobacterium tuberculosis complex(MTBC)were detected.NTM were detected in three water samples after sewage treatment in a tuberculosis prevention and control center,but none of the MTBC were detected.Conclusion In this survey,there is a risk that mycobacteria cannot be killed in sewage after treatment in tuberculosis hospitals,and sewage sampling and testing should be strengthened to ensure that the sewage of tuberculosis hospitals does not contain mycobacteria and prevent the occurrence of environmental contamination.
