Abstract

Antimicrobial-resistant (AMR) bacteria are a threat to global health. Epidemiological studies are necessary to gain a more detailed understanding of the transmission modality of resistant bacteria to wild animals and their diffusion into the environment to ensure a broader evaluation of the epidemiological role of wildlife. The study aimed to identify little-known epidemiological aspects by focusing on the isolation of Enterobacteriaceae in order to bring knowledge on the bacterial flora of wild mammals living in the National Park of Aspromonte (Calabria, Italy). Two hundred twenty-five faecal samples of wild mammals were collected and submitted to standard bacteriological examination for Enterobacteriaceae detection. Isolates were identified by mass spectrometry MALDI-TOF (matrix assisted laser desorption/ionisation - time of fligt mass spectrometry). The 30 isolates showing the highest number of resistances were screened for Extended Spectrum Beta Lactamase (ESBL) production. Antimicrobial susceptibility testing of the bacterial isolates was performed by the disk diffusion method. Two hundred sixty-three strains were isolated. The most frequently recovered bacterial species were Hafnia alvei, Escherichia coli and Citrobacter ...Continue Reading
