These bacteria were isolated, identified, serotyped with multiplex PCR, characterized by MLST and evaluated for drug susceptibility. The overwhelming majority of isolates (19/21) from goats and 1 isolate from sheep were identified as serotype 2, while only 1 isolate (1/21) from goat characterised as serotype 1. MLST profiles of Mannheimia haemolytica isolates revealed that these were diversity and most of isolates belong to ST44 (7/21) and ST7 (6/21). There were high levels of resistance against streptomycin (48%) and mezlocillin (43%) among the isolates. In conclusion, Mannheimia haemolytica isolated from goats in Jiangsu exhibited diversity of STs in genetics and simplicity in serotype. ©2018 PVJ. All rights reserved
