The objective of present study was to examine the prevalence and antimicrobial resistance of Mannheimia haemolytica isolated from the dead goats and sheep with pneumonia in Jiangsu, China. 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.
