Abstract

The increasing demand for meat of Philippine native swine (PNS) has led to the expansion of its low-cost farming, which exposes both the animal and farmer to zoonotic pathogens such as Salmonella. Multidrug-resistant pathogens can hamper treatment and spread globally. This study aimed to determine the presence of multidrug resistant Salmonella in PNS from Quezon province, Philippines. Fecal matter from PNS (n = 58) and environmental samples (n = 58) from 29 farms were tested for Salmonella. Fifteen (25.6%) PNS and 14 (24.1%) environmental samples were found positive for Salmonella. Logistic regression analysis indicated that swine age and farm management practices had no influence on the presence of Salmonella in PNS. Disk diffusion method against 11 antibiotic classes showed that Salmonella isolates from PNS were most commonly resistant to azithromycin (66.7%), tetracycline (53.3%) and ampicillin (46.7%). Five isolates exhibited multidrug resistance, namely, resistance to ampicillin, azithromycin and tetracycline (two isolates); resistance to ampicillin, azithromycin, tetracycline and amoxicillin-clavulanic acid; resistance to ampicilin, azithromycin and amoxicillin-clavulanic acid; and resistance to ampicillin, nalidixic acid and amoxicillin-clavulanic acid. These findings are the first on microbiological status of the PNS, and they provide useful information that may be adapted in developing management practices for effective and safe farming of PNS.
