spp. have been recognized as causative agents of various severe infections in pre-term or full-term infants as well as elderly adults suffering from serious underlying disease or malignancy. A surveillance study was designed to identify antibiotic resistance among clinical spp. strains, which were isolated from patients of two hospitals between May 2007 and August 2013. Altogether, 52 spp. isolates were analyzed. Although MALDI-TOF mass spectrometry recognized all and strains, it could not identify strain. Nevertheless, all strains were identified as spp. using multilocus sequence typing (MLST). Strains were tested against 17 types of antibiotics, using the standard microdilution method according to the 2018 European Committee on Antimicrobial Susceptibility Testing criteria. Three species were identified as (n = 33), (n = 18), and (n = 1); all isolates were susceptible to all tested antibiotics. All strains were PCR-negative for , , and β-lactamase genes, as well. Even though the results of this study showed that spp. isolates were pan-susceptible, continued antibiotic resistance surveillance is warranted. spp. have been recognized as causative agents of various severe infections in pre-term or full-term infants as well as elderly adults suffering from serious underlying disease or malignancy.
