A cross-sectional study on the AM use in pig production was conducted from April to July 2021 in Huong Tra town, Thua Thien Hue province. S. aureus isolates from nasal swab samples of pigs were used to assess AMR. The S. aureus strains were tested for AMR against 10 AM agents using the disk diffusion method. The results showed that AMs were used for both prevention (10/33 households
30.30%) and treatment (16/33 households
48.48%). There were 14/33 (42.42%) samples collected from pigs being positive for S. aureus. The S. aureus strains were shown to have a high frequency of resistant to oxytetracycline (86.67%)
oxacillin, doxycycline and linezolid (shared 73.33%). The most of the strains (93.33%) were resistant to at least one AM agent tested. The high frequency of the strains (86.67%) was showed multi-drug resistance. Notably, 7 strains were resistant to 6 different AM agents. The finding of this study is useful for clinical control of the diseases caused by this bacterium, as well as for the development of policies and clinical practice guidelines to reduce AMR.
