Urinary tract infections (UTIs) are common bacterial infections with significant health implications. This study aimed to assess the antimicrobial susceptibility (AST) patterns of isolated from urine samples over a decade (2014-2023).
The study analyzed isolates AST pattern from urine samples at a tertiary care hospital in Mysuru (Karnataka), South India using the VITEK-2 (bioMérieux, France) database.
Of 73,283 urine samples, 21,362 (29.15%) showed significant bacterial growth. The most frequently isolated organism was ( = 9,211, 43.11%), followed by ( = 1,108, 5.18%) and ( = 920, 4.30%). Of the 920 isolates, 385 (41.84%) were carbapenem-resistant (CRKP). Isolation rates were higher in males ( = 229, 59.48%) than females ( = 156, 40.52%), with a statistically significant -value (<0.0001). Carbapenem resistance rose from 3.70% in 2014 to 66.13% in 2021, then declined to 38.55% in 2023. Resistance to fluoroquinolones, aminoglycosides, and cephalosporins increased, with cephalosporin resistance exceeding 85% by 2023. These trends reflect growing drug resistance among .
The study reveals a significant rise in antimicrobial resistance in Klebsiella pneumoniae, particularly to carbapenems and fluoroquinolones. Effective treatment requires antibiotic stewardship, strict infection control, and ongoing surveillance to maintain therapeutic options.
尿路感染（UTIs）是常见的细菌感染，对健康有重大影响。本研究旨在评估过去十年（2014 - 2023年）从尿液样本中分离出的细菌的抗菌药敏（AST）模式。
该研究使用VITEK - 2（法国生物梅里埃公司）数据库分析了印度南部迈索尔（卡纳塔克邦）一家三级护理医院尿液样本中的细菌AST模式。
在73283份尿液样本中，21362份（29.15%）显示有显著细菌生长。最常分离出的病原体是肺炎克雷伯菌（n = 9211，43.11%），其次是大肠埃希菌（n = 1108，5.18%）和金黄色葡萄球菌（n = 920，4.30%）。在920株肺炎克雷伯菌分离株中，385株（41.84%）对碳青霉烯类耐药（CRKP）。男性的分离率（n = 229，59.48%）高于女性（n = 156，40.52%），P值具有统计学意义（<0.0001）。碳青霉烯类耐药率从2014年的3.70%上升到2021年的66.13%，然后在2023年降至38.55%。对氟喹诺酮类、氨基糖苷类和头孢菌素类的耐药性增加，到2023年头孢菌素类耐药率超过85%。这些趋势反映了肺炎克雷伯菌耐药性的不断增加。
该研究揭示了肺炎克雷伯菌的抗菌耐药性显著上升，尤其是对碳青霉烯类和氟喹诺酮类。有效的治疗需要抗生素管理、严格的感染控制和持续监测，以维持治疗选择。
