First report of qnr and blaVIM-4-like producing clinical Alcaligenes faecalis isolated in Türkiye; [Türkiye'den izole edilen qnr ve blaVIM-4-like üreten klinik Alcaligenes faecalis’in ilk raporu]

The study set out to look at the clinical strain of A. faecalis's antibiotic susceptibility pattern. Both biochemical and molecular approaches were used to identify A.faecalis. The VITEK compact system was used to analyze the strain's antibiotic susceptibility profile. The use of PCR was evaluated to determine the presence of resistance genes. It was also determined whether resistance determinants could be transferred. It was determined that A. feacalis showed resistance to imipenem, cefepime, ceftazidime, gentamicin, amikacin, netilmicin, tobramicin, ciprofloxacin, and levofloxacin. The blaVIM-4-like gene was present in this strain, according to the results of the PCR and DNA sequencing studies. In contrast to VIM-4, this blaVIM-4-like gene showed one amino acid change (Ala265Val).Filter-mating experiments showed that the blaVIM-4-like gene cannot be transferred from A. faecalis to E. coli. In this study, This research, demonstrated the presence of the blaVIM-4-like gene for the first time in A. faecalis from Turkey.
