Urinary tract infection (UTI) is the most common clinical finding during pregnancy, and if it is asymptomatic bacteriuria (ASB), it can progress to pyelonephritis, leading to further complications. The present study aims to know the prevalence of ASB in pregnant females and the antimicrobial resistance pattern in our hospital setup.
A total of 552 urine samples were collected from pregnant females (with no symptoms of UTI) both attending outpatient department and admitted in the wards of obstetrics and gynecology department. Urine culture was performed on blood agar, MacConkey agar, and UTI chromogenic agar. Antibiotic sensitivity test was done using Kirby-Bauer disc diffusion method, and the results were interpreted.
The prevalence rate of ASB in pregnant females was 17.4%. It was common in the age group of 25-33 years (60.4%). The infection rate was higher in the second trimester (43.7%) compared to the third (29.2%) and first (27.1%) trimester. Multiparity (60.4%) was a common finding in ASB during pregnancy. There was a significant finding of previous history of UTI (22.9%) and anemia (58.3%) associated with ASB in pregnant females. (39.2%) was the most common microorganism isolated followed by (34.3%), (14.7%), (4.9%), coagulase-negative spp. (2.9%), and and (1.9%). Most sensitive drugs to be given in ASB during pregnancy were nitrofurantoin and fosfomycin.
It was emphasized that urine culture should be done in early antenatal visit as routine screening to identify ASB in pregnant females as it can prevent fetal and maternal complications.
尿路感染(UTI)是孕期最常见的临床症状,若为无症状菌尿(ASB),则可能发展为肾盂肾炎,进而引发更多并发症。本研究旨在了解我院孕妇中ASB的患病率及抗菌药物耐药模式。
共收集了552份来自门诊及妇产科病房的孕妇尿液样本(无UTI症状)。在血琼脂、麦康凯琼脂和UTI显色琼脂上进行尿培养。采用 Kirby-Bauer 纸片扩散法进行抗生素敏感性试验,并对结果进行解读。
孕妇中ASB的患病率为17.4%。在25 - 33岁年龄组中最为常见(60.4%)。与孕晚期(29.2%)和孕早期(27.1%)相比,孕中期的感染率更高(43.7%)。多胎妊娠(60.4%)是孕期ASB的常见表现。孕妇ASB伴有UTI既往史(22.9%)和贫血(58.3%)的情况较为显著。分离出的最常见微生物为大肠埃希菌(39.2%),其次是肺炎克雷伯菌(34.3%)、粪肠球菌(14.7%)、奇异变形杆菌(4.9%)、凝固酶阴性葡萄球菌属(2.9%)以及金黄色葡萄球菌和表皮葡萄球菌(1.9%)。孕期ASB最敏感的药物为呋喃妥因和磷霉素。
强调应在产前早期检查时常规进行尿培养,以识别孕妇中的ASB,因为这可以预防母婴并发症。
