This study was to explore bacterial communities and antimicrobial resistance in airborne dust from pig farms. Airborne dust, pig feces, and feed were collected from nine pig farms (n=9) in Thailand, including Nakhon Sawan, Chainat, Supan Buri, Lopburi, and Saraburi, during the rainy season from May to October 2022. The farms were selected based on the owners' willingness to participate in the study and the availability of veterinarians or animal health practitioners. Airborne dust samples were collected at three different locations of the selected pig house, including upwind and downwind (25 m from pig house), and inside (at the center of the pig house). Pig feces and feed samples were individually collected from the pen floor and feed trough from the same pig house where airborne dust was collected. Direct total bacteria count on each sampling plate was conducted and averaged. The ESKAPE bacteria, Escherichia coli, Salmonella, and Streptococcus were examined. A total of 175 bacterial isolates were collected and tested for minimum inhibitory concentration. Pooled bacteria from inside airborne dust samples were analyzed using Metagenomic Sequencing. The results showed that the bacterial concentration inside pig houses was highest (1.9–11.2 × 103 CFU/m3). Various resistance phenotypes were observed among the target bacteria, while the same bacterial species with the same resistance phenotype were discovered in airborne dust, feed, and feces in each farm. Staphylococcus (n = 37) and Enterococcus (n = 36) were the most frequent bacterial species. Salmonella (n = 3) was exclusively isolated from feed and feces. Metagenomic sequencing analysis revealed 1,652 bacterial species, of which Staphylococcus chromogenes was the most common bacterial species across all pig farms. The predominant bacterial phyla observed in airborne bacterial communities inside pig houses were Bacillota or Firmicutes, and Pseudomonadota. AMR genes (n = 159) from 12 different antibiotic classes were identified, with aminoglycoside resistance genes (24%) being the most prevalent. Various plasmids (n = 251) were identified, and the same plasmid was detected in multiple farms. The highest number of plasmids were detected in Farm 6 (n = 72). In conclusion, airborne dust from pig farms contained a variety of bacterial pathogens, of which target bacteria were resistant to multiple clinically important antibiotics. Various AMR genes and plasmids were identified. The important role of airborne dust from pig farms in the distribution of AMR bacterial pathogens is highlighted. Policy measurements to address AMR in airborne dust from livestock farm is suggested.
