Urinary tract infection (UTI) is the most commonly acquired bacterial infection. Bacterial biofilms play an important role in urinary tract infections and are responsible for persistent infections as well as higher antimicrobial resistance. The microbial biofilms pose a public health problem as the microorganisms in the biofilms are difficult to treat with antimicrobial agents. So the present study was undertaken with the aim to study biofilm production and antimicrobial susceptibility pattern of urinary isolates. Aerobic bacterial isolates from urine samples submitted to microbiology laboratory for culture were included in the study. The isolates were tested for biofilm formation by Congo red agar method and Christensen tube method. Antimicrobial susceptibility tests were performed on these isolates by Kirby Bauer disk diffusion method as per CLSI guidelines. A total of 293 Gram negative bacilli and 59 Gram positive cocci were tested for biofilm production and antimicrobial susceptibility testing. : Gram‑negative organisms were predominant (83.24%) of all the isolates. Biofilm production was detected in 47% of the isolates. 51.7%), were the most common biofilm producing Gram negative bacilli followed by (44.32%). Amongst Gram positive cocci, (77.8%) was the most common biofilm producing organism. Biofilm producing urinary isolates displayed relatively less percentage of antimicrobial susceptibility than biofilm non producers. Biofilm forming isolates showed higher antimicrobial resistance as compared to biofilm non producer. Early detection of biofilm production in urinary isolates may aid clinicians in treatment of urinary tract infections.

Background: Globally, urinary tract infection (UTI) is considered a major public health concern and the second most common bacterial infection affecting individuals of different ages worldwide. Urinary tract infections (UTIs) are caused by multiplicity of microorganisms. The chronicity of different bacterial isolates and their propensity to various antibiotics may differ widely, particularly in hospitalized patients, that makes the study of susceptibility pattern mandatory for a proper selection of antibiotics. Objective: To evaluate antimicrobial susceptibility pattern of the Gram negative organisms isolated from urine cultures of hospitalized patients. Material and Methods: A total of 500 urine samples from hospitalized patients which showed significant bacteriuria were studied. Samples were inoculated on Blood agar and MacConckey agar. Further identification and study of organisms was done by standard Microbiological methods. Antimicrobial Susceptibility pattern was studied by Modified Kirby- Bauer’s disc diffusion method with the panel of 15 drugs as per Clinical Laboratories Standard Institute (CLSI) guidelines. Results: UTIs were found more common in females 290 (58%). Commonest organism found was Escherichia coli 260 (52%) followed by Klebsiella spp. 120 (24%), Pseudomonas spp. 40 (8%), Proteus spp. 38 (7.6%), Citrobacter spp. 25 (5%) and Acinetobacter spp. 17 (3.4%). Majority of the strains were found sensitive to nitrofurantoin followed by amikacin, piperacillin-tazobactam and cotrimoxazole. Commonly prescribed fluroquinolones were found least effective for treatment of UTI. All the strains were found sensitive to imipenem. Extended spectrum beta lactamase (ESBL) was noted in E.coli and in Klebsiella spp. Conclusion: To discourage the indiscriminate use of antibiotics and to prevent further development of bacterial drug resistance, proper knowledge of susceptibility pattern of uropathogens in particular area is very important before prescribing any empirical antibiotic therapy.

Abstract Background: Urinary tract infection is one of the most common bacterial infections in children. Understanding the characteristics of uropathogens and their antimicrobial susceptibility pattern in a particular setting can provide evidence for the appropriate management of cases. This study aimed to assess the bacterial profile of urinary tract infection, their antimicrobial susceptibility pattern and associated factors among clinically suspected children attending at Felege-Hiwot Comprehensive Specialized Hospital, Northwest Ethiopia.Methods: A hospital-based cross-sectional study was conducted from February-April, 2019. A systematic sampling technique was employed. A mid-stream urine sample was inoculated on cystine lactose electrolyte deficient media and incubated for 24-48 hours. Sub-culturing was done on Mac-Conkey and blood agar. Antimicrobial susceptibility test was done on Muller-Hinton agar. A binary logistic regression model was used to see the association between dependent and independent factors. A p-value<0.05 at 95% CI was considered as statistically significant.Results: The overall prevalence of urinary tract infection was 16.7% (95% CI 12.4-21.1). Both Gram-negative and Gram-positive bacterial isolates were recovered with a rate of 44/50 (88%) and 6/50 (12%) respectively. Among Gram-negative isolates, E. coli 28/44(63.6%) was predominant while S. saprophyticus 2/6(33.3%) was prevalent among Gram-positive bacterial isolates. Overall, a high level of resistance to ampicillin, augmentin, and tetracycline was shown by Gram-negative bacteria with a rate of 44/44(100%), 39/44(88.6%), and36/44 (81.8%) respectively. About 33/50(66%) of overall multidrug resistance was observed (95% CI 52-78). About six Gram-negative bacterial isolates were extended spectrum beta-lactamase (ESBL) producers. Having a history of urinary tract infection (P-0.003, AOR 1.86-22.15) and male uncircumcision (p-0.00, AOR 5.5-65.35) were the independent variables that associate for urinary tract infections.Conclusion: In the present study, the prevalence of urinary tract infection among children was high and considerably a high proportion of multidrug resistance was observed. This result will have a significant impact on the selection of appropriate antimicrobial agents for the treatment of urinary tract infection.

Urinary tract infection causes considerable morbidity in diabetic patients and if complicated, can cause severe renal damage and life-threatening infections. The escalating antimicrobial resistance rate among bacteria over the past years is another concern in the treatment of urinary tract infections. This study investigated the prevalence, antimicrobial susceptibility pattern of the isolates and associated factors of urinary tract infection among adult diabetic patients attending Metu Karl Heinz Referral Hospital, Southwest Ethiopia. An institutional-based cross-sectional study was conducted among 233 adult diabetic patients selected using simple random sampling technique. Data were collected using a structured questionnaire. Clean-catch midstream urine samples were investigated for the presence of pathogenic bacteria and their antimicrobial susceptibility pattern using recommended culture methods. Data were entered, cleaned, and analyzed using the Statistical Program for Social Sciences version 21.0. Statistical significance was set at ap-value < 0.05. The prevalence of urinary tract infection was 16.7% (95%, CI: 12.0, 21.5). The predominant isolates wereEscherichia coli(25.6%) andKlebsiellaspp. (20.5%).E. coliisolates showed higher sensitivity to ceftriaxone (80%), ciprofloxacin (70%), and gentamycin (70%), but resistant to tetracycline (60%).Staphylococcus aureuswas sensitive to amoxicillin-clavulanic acid (85.7%), and gentamycin (57.1%), while resistant to tetracycline (85.7%), nitrofurantoin (85.7%), and ampicillin (71.4%). The odds of developing urinary tract infections were significantly higher in diabetic females (AOR: 3.56, 95% CI: 1.44, 8.76), those who were not able to read and write (AOR: 2.55, 95% CI: 1.19, 5.49) and those with a history of urinary tract infection (AOR: 2.31, 95% CI: 1.09, 4.90) compared with their counterparts. In this study, the prevalence of urinary tract infection among diabetic patients was relatively comparable with the previous studies conducted in Ethiopia. Management of urinary tract infection in diabetic patients should be supported with culture and antimicrobial susceptibility testing.
