In order to obtain basic data on biohazard assessment and safety index for the reuse of treated sewage, identification, drug resistance and phage sensitivity on salmonellae isolated from various processes of a sewage treatment plant were investigated.
(1) Density of salmonellae which flow into the sewage treatment process showed weekly and daily changes.
(2) The greatest density on salmonellae was 110MPN/100ml of sewage during the investigation period.
(3) 29isolates of salmonellae were divided into 41% of BGI, 55% of BGIV and 4% of BGV, respectively.
(4) 42% of BGI and 62% of BGIV had resistance to penicillin, 17% of BGI and 12% of BGIV and 100% of BGV had resistance to two and more kinds of drug.
(5) 75% of BGI and 94% of BGIV had phage sensitivity.
(6) The greatest density on Salmonella phage was 550PFU/ml of raw wastewater for investigation period.
