Carbapenem-Resistant Acinetobacter baumannii Recovered from Swine Manure

Recently, concerns have been raised about the possibility of Acinetobacter baumannii transmission between animals and humans. So far, A. baumannii has been reported in animals with which people can come into contact. The presence of this pathogen in animal manure presents an equally important public health risk. In this study, we report the finding of two A. baumannii isolates in swine manure from a Croatian pig farm. Both isolates shared features with the widespread human clinical isolates: affiliation to the international clonal lineage 2 (ST-195), carbapenem, and extensive drug resistance and the plasmid-located acquired blaOXA-23 gene. These two A. baumannii isolates survived anaerobic conditions, competition with other microorganisms, and elevated concentrations of heavy metals in the stagnant swine manure for at least 2 weeks. These findings call for bacteriological analysis and disinfection of liquid swine manure before its application as a fertilizer in traditional extensive agriculture.
