“…As Rebelo et al . (2023) we observed that some E. gallinarum strains showed resistance to ciprofloxacin. In addition, we also found resistance to enrofloxacin, levofloxacin, and norfloxacin in some E. gallinarum strains isolated from chicken, quail and turkey meat.…”

“…We observed high resistance rates against tetracyclines, with values between 54.17% in pork meat and 70.27% in chicken meat. These results are in agreement with those found in the literature (Aslam et al ., 2012; Noh et al ., 2020; Rebelo et al ., 2023). The resistance to tetracyclines found could be explained since these antimicrobials are often used in farm animal treatments.…”

“…However, neither E. durans nor E. gilvus strains showed resistance to any of the four antimicrobials tested (Table 2). As other authors, we observed higher resistance to ciprofloxacin for E. faecium than for E. faecalis , except in duck meat (Rebelo et al ., 2023). In contrast, Aslam et al .…”

“…Moreover, we detected resistance to linezolid in E. faecalis and E. gallinarum strains isolated from chicken and turkey meat, and in E. hirae isolated from turkey meat (Table 2). Other authors have not found resistance to linezolid in E. faecalis, E. gallinarum or E. hirae strains isolated from chicken or turkey (Aslam et al ., 2012; Rebelo et al ., 2023). The resistance to linezolid and teicoplanin is of special concern, since these antimicrobials are used for severe enterococci infections treatment, as an option to vancomycin‐resistant enterococci (Riccardi et al ., 2021).…”

“…We found two strains resistant to vancomycin, one E. faecalis from turkey and one E. faecium from quail (Table 2). In contrast, other authors have not found resistance to vancomycin in enterococci isolated from animals or meat (Fracalanzza et al ., 2007; Aslam et al ., 2012; Jahan et al ., 2013; Thu et al ., 2019; Noh et al ., 2020; Rebelo et al ., 2023). As Kim & Koo (2020) we did not isolate any resistant enterococci to vancomycin from pork meat.…”

There is a great concern on the presence of antimicrobial-resistant bacteria in meat, since they can cause adverse effects in the consumers' health. The purpose of this work was to identify and characterise the antimicrobial resistance of Enterococcus spp. isolated from meat. A total of 209 meat samples (forty pork, fifty chicken, fifty-one turkey, thirty-one duck, and thirty-seven quail) were collected at retail level. E. faecalis was the dominant enterococci isolated from all the types of meat evaluated, followed by E. faecium, E. gallinarum, and E. hirae, among others which were also isolated. Of the 317 strains evaluated for antimicrobial resistance 48 (15.14%) were multi-resistant. Most of the multi-resistant strains were E. faecium and E. faecalis, and in lesser extent E. gallinarum and E. hirae. Multi-resistant strains were isolated from all the types of meat studied, mainly from turkey (sixteen strains), chicken (fifteen strains), and quail (fourteen strains). Two multi-resistant strains showed resistance to vancomycin (E. faecium isolated from turkey meat, and E. faecalis isolated from quail meat). Resistance to tigecycline, teicoplanin, linezolid and quinolones was found among enterococci isolates. Special measures should be taken to avoid faecal contamination of carcasses in order to reduce enterococci prevalence in meat.
