Abstract

The use of antimicrobials for feeding and treatment is crucial to animal health. However, continuous use of antibiotics is contributing to emergence and widespread of antibiotic resistance. This study aimed to investigate the antimicrobial resistance of five major respiratory pathogens in pigs of Hubei province, China, from October to December, 2019. Antibiotic susceptibility testing for Streptococcus suis, Haemophilus parasuis, Pasteurella multocida, Bordetella bronchiseptica and Actinobacillus pleuropneumoniae was determined to representatives of relevant antibiotic classes.

Streptococcus suis isolates were mostly sensitive to beta-lactams, whereas high levels of resistance were observed to quinolones, gentamycin, doxycycline, trimethoprime and lincomycin. For H. parasuis, P. multocida and A. pleuropneumoniae of Pasteurellaceae family, the susceptibility to beta-lactams and quinolones was displayed. Most \textit{B. bronchiseptica} isolates were sensitive to doxycycline, azithomycin, polymycin whereas high resistance levels to beta-lactams, aminoglycosides and quinolones were recorded.

This study obtained practical data for later studies and usage to combat infections due to respiratory bacteria.
