Pharyngeal Communities and Antimicrobial Resistance in Pangolins in Gabon

Wildlife can be a reservoir and source of zoonotic pathogens for humans. For instance, pangolins were considered one of the potential animal reservoirs of SARS-CoV-2. The aim of this study was to assess the prevalence of antimicrobial-resistant species (e.g., extended-spectrum β-lactamase [ESBL]-pro...

    Wildlife can be a reservoir and source of zoonotic pathogens for humans. For instance, pangolins were considered one of the potential animal reservoirs of SARS-CoV-2. The aim of this study was to assess the prevalence of antimicrobial-resistant species (e.g., extended-spectrum β-lactamase [ESBL]-producing 'Enterobacterales') and 'Staphylococcus aureus'-related complex and to describe the bacterial community in wild Gabonese pangolins. The pharyngeal colonization of pangolins sold in Gabon (n = 89, 2021 to 2022) was analyzed using culture media selective for ESBL-producing 'Enterobacterales, S. aureus-related' complex, Gram-positive bacteria and nonfermenters. Phylogenetic analyses of ESBL-producing 'Enterobacterales' was done using core-genome multilocus sequence typing (cgMLST) and compared with publicly available genomes. Patterns of cooccurring species were detected by network analysis. Of the 439 bacterial isolates, the majority of species belonged to the genus 'Pseudomonas' (n = 170), followed by 'Stenotrophomonas' (n = 113) and 'Achromobacter' (n = 37). Three 'Klebsiella pneumoniae' isolates and one 'Escherichia coli' isolate were ESBL-producers, which clustered with human isolates from Nigeria (MLST sequence type 1788 [ST1788]) and Gabon (ST38), respectively. Network analysis revealed a frequent cooccurrence of 'Stenotrophomonas maltophilia' with 'Pseudomonas putida' and 'Pseudomonas aeruginosa'. In conclusion, pangolins can be colonized with human-related ESBL-producing 'K. pneumoniae' and 'E. coli'. Unlike in other African wildlife, 'S. aureus-related' complex was not detected in pangolins.
