“…A relatively high level resistance of ESBLproducing bacteria was observed on aztreonam, trime thoprim/sulfamethoxazole, gentamicin, and ciprofloxacin, by 86.36%, 77.27%, 72.73%, and 68.18% consecutively, as the previous study with relatively high level of resistance of ciprofloxacin (50.0%), gentamicin (60.0%), trimethoprimsulfamethoxazole (60%, and ciprofloxacin (40.0%) (Cormican et al, 1996;et alKürekci et al, 2017;Sudarwanto et al, 2017). Other antibiotics such as ertapenem and mempenem from carbapenem class, amikacin (aminoglycoside class), and tigecycline (tetracycline class) still show high level of sensitivity (100%), according to mechanism of action of ESBL which hydrolyze penicilin class antibiotics, first, second, and third generations of cephalosporin, and monobactam antibiotic class, but inactive on carbapenem class (imipenem, meropenem, ertapenem) (Lim et al, 2013;Biutifasari, 2018).…”
