ABSTRACT
BACKGROUND:
Bacteria that cause urinary tract infections (UTIs) are found with different frequencies in different regions; moreover, antibiotic susceptibility can also vary by region. We retrospectively studied and compared the species and antimicrobial susceptibility of bacterial pathogens isolated from patients with UTIs in the northern Gyeonggi-do area.METHODS:
We analyzed urine specimens collected from patients who visited the Myongji Hospital between 2007 and 2011. The urine specimens were cultured, and bacteria were identified by biochemical examination with an API kit (bioMerieux Inc., USA). Antimicrobial susceptibility was determined by the disc diffusion method and the Vitek II system (bioMerieux Inc., USA).RESULTS:
A total of 11,818 (31.4%) urine specimens were culture positive. The most common species identified were Escherichia coli (37.1%), Klebsiella pneumoniae (7.4%), Enterococcus faecium (6.1%), and Candida spp. (5.5%). The proportion of isolates producing extended-spectrum beta-lactamases significantly increased during the study period.CONCLUSIONS:
E. coli, K. pneumoniae, and E. faecium were the 3 most common organisms identified. Of note, however, was the increasing frequency of Pseudomonas spp. and Proteus spp. isolated during the more recent years. Further studies are required from other centers in the northern Gyeonggi-do area.
