Resistant Escherichia coli isolated from wild mammals from two rescue and rehabilitation centers in Costa Rica: characterization and public health relevance

The study analyzed antimicrobial resistance (AMR) and virulence profiles of 67 Escherichia coli isolates from faecal samples of 77 wild mammals in Costa Rica. It found that 48% of the isolates were multidrug-resistant, with the highest resistance levels towards commonly prescribed antimicrobials. Isolates from rehabilitated animals or those treated with antibiotics had higher AMR levels. The study suggests that AMR is a widespread issue in Costa Rican wildlife, highlighting the need for further research.
