TNU Journal of Science and Technology 228(01): 201 - 210 EVALUATION OF LYTIC ACTIVITY OF BACTERIOPHAGES IN DIFFERENT CONDITIONS AGAINST MULTI-ANTIBIOTIC RESISTANCE ESCHERICHIA COLI ISOLATED FROM PANGASIUS HYPOPHTHALMUS PRODUCTION CHAIN Tong Thi Anh Ngoc, Tran Thi Mong Cam, Pham Kim Duyen Tran Tram Anh, Nguyen Cam Tu, Nguyen Thi Thu Nga* Can Tho University ARTICLE INFO ABSTRACT Received: 03/6/2022 This study was conducted to evaluate the lytic activity of bacteriophages (phage N9 and B80) against multi-antibiotic resistance Escherichia coli isolated from Pangasius production chain were tested on simulated media of filleted Pangasius and chicken extracts at different MOI (100-1000) and incubated at 4±1oC The results showed that lytic activity of both phage N9 (MOI 1000) and B80 (MOI 100) against their bacterial hosts were achieved during from to 24 h exposure, specially E coli count were
