This research investigated antibiotic resistant bacteria (ARB) in soil receiving wastewater and sludge of smallholder swine farms in northern Thailand. Soil samples were collected from four study sites including soil that received untreated effluent, soil that received sludge from a pond system, soil that received sludge from a biogas system, and soil around swine farm without swine waste amendment. Properties of the soil samples were also examined and the results showed that the soil receiving untreated swine wastewater and soil receiving sludges contained a high volume of nitrogen, phosphorus, and organic matter when compared to soil without swine waste amendment. Most of the ARBs found in the soil were circular-form colonies, rod-shaped cells, and gram-positive and most of them resisted Lincomycin and Amoxicillin. ARBs in soil receiving untreated effluent and soil receiving sludges appeared to be Serratia, Bacillus, Rossellomorea, and Aeromonas. While, ARBs in the groups of Chryseobacterium and Pseudomonas were found only in the soil without swine waste amendment. Almost all the ARBs found in this study were identified to be multidrug resistant bacteria. The findings indicated the appearance of ARBs in the swine farm environment were encouraged by releasing of antibiotic contaminated swine wastes into the environment. This affects antibiotics use in swine farms, antibiotics use for infectious disease treatments and control in humans, and public health systems. [ABSTRACT FROM AUTHOR] |
