The study aims to speciate clinical isolates and detect their biofilm-forming ability and antifungal resistance.
All the spp. isolated from different clinical samples like pus, urine, blood, and body fluid were included in the study. Biofilm production was tested by the microtiter plate method. Antifungal susceptibility was studied by the disk diffusion method. Patient's demographic details such as age, sex, and clinical information were collected. Presence of other risk factors such as diabetes mellitus, history of antibiotic use, and any urinary tract instrumentations was also recorded.
Among 90 species isolated, most predominant species was found to be (45.5%) followed by (28.88%), (20%), (3.33%), and (2.22%). spp. were isolated from urine (43%), BAL/sputum (18.88%), high vaginal swab (8.88%), suction tips (7.77%), blood and wound swabs (6.66%), pus (3.33%), bile aspirate (2.22%), and deep tissue (1.11%). A larger number of females were affected than males, and the age group of 51 to 60 years was more susceptible to candidiasis. A higher number of isolates produced biofilm followed by , , and However, showed no biofilm production in our study. All isolates were 100% sensitive to amphotericin B. Voriconazole was the next effective drug with 81.11% susceptibility. 24.44% of strains were resistant to fluconazole.
Speciation of isolates, detection of ability to form the biofilm, and monitoring of antifungal susceptibility testing are necessary for appropriate treatment.
本研究旨在对临床分离株进行菌种鉴定,检测其生物膜形成能力和抗真菌耐药性。
本研究纳入了从脓液、尿液、血液和体液等不同临床样本中分离出的所有菌种。采用微量滴定板法检测生物膜的产生情况。采用纸片扩散法研究抗真菌药敏性。收集患者的人口统计学细节,如年龄、性别和临床信息。还记录了其他危险因素的存在情况,如糖尿病、抗生素使用史和任何尿路器械操作史。
在分离出的90种菌种中,最主要的菌种是(45.5%),其次是(28.88%)、(20%)、( 3.33%)和(2.22%)。菌种从尿液(43%)、支气管肺泡灌洗/痰液(18.88%)、高阴道拭子(8.88%)、吸头(7.77%)、血液和伤口拭子(6.66%)、脓液(3.33%)、胆汁抽吸物(2.22%)和深部组织(1.11%)中分离得到。受影响女性的数量多于男性,51至60岁年龄组更容易患念珠菌病。产生生物膜的分离株数量较多,其次是、和。然而,在我们的研究中未显示出生物膜的产生。所有分离株对两性霉素B均100%敏感。伏立康唑是下一个有效的药物,药敏率为81.11%。24.44%的菌株对氟康唑耐药。
对分离株进行菌种鉴定、检测生物膜形成能力以及监测抗真菌药敏试验对于适当的治疗是必要的。
