ABSTRACT
Introduction: The use of urinary catheter benefit patients who are unable to urinate for various medical rea-sons. Despite its use, a urinary catheter during its application may introduce bacteria to the urinary tract and result in Urinary tract infection (UTI). Even though the burden of catheter-associated UTI is expected to be high in resource-limited countries, there is limited data. The aim of this study was to determine the magnitude of culture-confirmed catheter-associated urinary tract infection (CAUTI), associated factors, and antimicrobial sus-acceptability profiles of bacteria. Methods: This prospective cross-sectional study was conducted at Hawassa University Comprehensive Specialized Hospital (HUCSH), Sidama region, from May-August 2022. One hundred forty-nine catheterized patients at HUCSH were included. Socio-demographic, clinical, and laboratory data were collected using structured questionnaire. Urine specimens were cultured on blood and MacConkey agar. Culture-confirmed catheter-associated urinary tract infection was established if >1 X 105colonies of bacteria per milliliters of urine was detected. The disc diffusion method was used for antimicrobial susceptibility testing. For data analysis, SPSS version 26 was used. Factors associated with culture confirmed CAUTI were assessed using binary logistic regression. Results: The magnitude of culture confirmed CAUTI was 30.2% (n=45; 95% CI=22.8−37.6). The most common bacterial isolates were Escherichia coli (n=12; 26.7%), followed by Klebsiella species (n=10; 22.2%), and Staphylococcus aureus (n=6; 13.3%). Duration of catheterization (AOR=9.6, 95% CI=3.8−24.2) and comorbidities (AOR=4.1, 95% CI=1.7−9.8) were significantly associated with culture-confirmed CAUTI. Most Gram-neg-active bacteria were resistant to commonly prescribed antimicrobial agents. Conclusions:The magnitude of culture-confirmed CAUTI at HUCSH was high.E.coli was the leading bacteria and most of them were resistant to various types of antimicrobial agents. Duration of catheterization and comorbidities were significantly associated with culture-confirmed CAUTI

Introduction: The genus Myroides comprises of Gramnegative, non-motile, and non- fermenting bacteria. It is arare opportunistic pathogen but many recent case reports,however, underscore the pathogenic potential that Myroidesspp. possesses for humans. Immunocompromised patients areat higher risk for Myroides infection. Diabetes, catheterizationand ICU stay may increase the chances of acquiring Myroidesinfection.Material and Methods: Urine specimens collected frominpatients were cultured as per standards. Myroides spp.were identified and sensitivity was performed on VITEK® 2Compact™.Results: A total of 16 Myroides spp. isolates were obtainedin the study period. All the isolates were from catheterizedpatients residing in intensive care units. Eleven (69%) patientswere suffering from diabetes mellitus. Extensive resistancewas seen in antibiotic sensitivity results. Minocycline was100% sensitive.Conclusion: Myroides spp. should be considered amongpathogens in hospitalized, catheterized patients. They couldbe extremely drug resistant. Minocycline is a useful antibioticwhile treating UTI caused by Myroides spp.
ABSTRACT
Aim This study was carried out to determine the prevalence of asymptomatic bacteriuria in pregnant women attending a teaching hospital in rural setup. Materials and Methods A total of 600 women were recruited for this study. A total of 200 antenatal women were clinically identified to have no signs and symptoms of UTI, 200 antenatal women were having signs and symptoms of UTI, and 200 were non-pregnant women that were studied as controls. Clean catch midstream urine samples were collected from each patient into a sterile universal container from Gynecology and obstetrics department and general medicine department. The urine samples were examined microscopically and by the cultural method. Identification of isolates was carried out by a standard microbiological technique. Result A total of 272 (45.3%) were positive for significant bacteriuria. There was a significant difference in the prevalence of asymptomatic bacteriuria with respect to age (P< 0.0001). Trimester did not show any significant difference (P = 0.2006) in the prevalence of asymptomatic bacteriuria. Escherichia coli was the most predominant organism followed closely by Klebsiella species. Nitrofurantoin, ampicillin, and levofloxacin were mostly used antibiotics. Conclusion Asymptomatic bacteriuria is not uncommon among antenatal patients in the population studied. Routine urine cultural test should be carried out on all antenatal patients in order to identify any unsuspecting infection. This measure will go a long way in reducing maternal and obstetric complications associated with pregnancy.
ABSTRACT
Objectives: Urinary tract infection (UTI) as a result of Candida spp. is becoming increasingly common in hospitalized setting. Clinicians face dilemma in differentiating colonization from true infection and whether to treat candiduria or not. The objective of the present study was to look into the significance of candiduria in catheterized patients admitted in the ICUs and perform microbiological characterization of yeasts to guide treatment protocols. Materials and Methods: One hundred consecutive isolates of Candida spp. from the urine sample of 70 catheterized patients admitted in the ICU were collected and stocked for further characterization. A proforma was maintained containing demographic and clinical details. Blood cultures were obtained from all these 70 patients and processed. Species identification of yeasts was done on VITEK. Results: Candiduria was more common at extremes of age. The mean duration of catheter days was 11.1 ± 6 days. Other associated risk factors such as diabetes mellitus and antibiotic usage were seen in 38% and 100% of our study group. Concomitant candidemia was seen in 4.3% of cases. Non-albicans Candida spp. (71.4%) emerged as the predominant pathogen causing nosocomial UTI. Conclusion: The present study reiterates the presence of candiduria in catheterized patients, especially in the presence of diabetes and antibiotic usage. Non-albicans Candida spp. are replacing Candida albicans as the predominant pathogen for nosocomial UTI. Hence, we believe that surveillance for nosocomial candiduria should be carried out in hospitalized patients.
