Abstract. Suhartono S, Mahdani W, Hayati Z, Nurhalimah N. 2021. Species distribution of Enterobacteriaceae and non-Enterobacteriaceae responsible for urinary tract infections at the Zainoel Abidin Hospital in Banda Aceh, Indonesia. Biodiversitas 22: 3313-3318. Urinary tract infection (UTI) is an infection that occurs along the urinary tract caused by pathogenic bacteria. Enterobacteriaceae and non-Enterobacteriaceae are generally normal flora originating from the large intestine and vaginal mucosa. This study aimed to assess the distribution of Enterobacteriaceae and non -Enterobacteriaceae pathogens that cause UTI based on species diversity, patient age, gender, and hospital units, and to evaluate their antibiotic sensitivity to uropathogens in ZAH. In total, there were 284 isolates classified as UTI pathogens with 178 Enterobacteriaceae isolates dominated by Escherichia coli and 107 non- Enterobacteriaceae isolates. Non- Enterobacteriaceae consisted of 77 isolates of Gram-positive dominated by Enterococcus faecalis and Enterococcus facium, and 29 isolates of Gram-negative dominated by Acinetobacter baumannii. The highest UTI ratio was found in the elderly (56-65 years), namely 66.2% Enterobacteriaceae and 33.8% non-Enterobacteriaceae isolates. Based on gender, females were infected with Enterobacteriaceae (66.86%) and non-Enterobacteriaceae (37.41%). Most of UTI patients in the internal medicine unit were infected with Enterobacteriaceae (55.36%) and non-Enterobacteriaceae (44.64%). Amikacin, meropenem, and levofloxacin were antibiotics that had high sensitivity against Enterobacterial and non-Enterobacterial uropathogens. The emergence of Gram-positive uropathogens need to be concerned as these groups start emerging. It is also important to monitor regularly the antibiotic susceptibility of bacterial UTI pathogens to ensure the efficacy of current UTI treatments and minimize the UTI incidence in nosocomial settings.
