Background: Urinary tract infection is very common in both male and female.Objectives: The purpose of the present study was to see the antibiotic sensitivity pattern of isolated from urinary tract infected patients.Methodology: This cross sectional study was carried out in Dhaka Medical College Hospital, Dhaka for a period of 12 months. Clinically diagnosed cases of urinary tract infection irrespective of age and sex having pus cells ?5/HPF in the deposits of centrifuged urine were selected as study population. Data regarding organisms causing UTI and their antibiotic sensitivity patterns were collected. For urine culture the urine samples were inoculated on HiCrome UTI agar, CLED agar, 5% sheep blood agar and MacConkey’s agar media with a calibrated loop having diameter of 1.45 mm which contains 0.001 ml of urine. The inoculation at 37o C for 24 hours and CFU count of 105/ml of urine were considered positive for UTI. Identification of bacteria was done by standard biochemical techniques and their distinct colony characteristics. All the isolated organisms were tested for antimicrobial sensitivity against different antimicrobial agents by disc diffusion method on Mueller-Hinton agar plates.Result: Diagnosis of bacteria causing UTI with their sensitivity to different antibiotics was performed with a total of 300 samples from both male (38.66%) and female (61.33%) of different age groups. Among 300 samples 107 strains were isolated. Out of 107 identified strains, 95(31.67%) samples showed single growth and 6(2%) samples showed mixed growth. Escherichia coli (64.49%) was found to be the predominant organism. Regarding antimicrobial sensitivity pattern Esch. coli showed 98.55 to 63.77% sensitivity to imipenem, amikacin, ceftazidime and nitrofurantoin. Other isolated organisms showed 50 to 100% sensitivity to ceftazidime, amikacin, imipenem except Klebsiella, Pseudomonas and enterococci spp. which showed 40% and less sensitivity.Conclusion: In conclusion Escherichia coli is the most commonly isolated bacteria which is highly sensitive to imipenem.Bangladesh J Infect Dis 2015;2(1):13-18

Objectives: The objective of this study was to determine the prevalence of urinary tract infection (UTI) and antibiotic sensitivity pattern among the suspected UTI cases visiting at Ganeshman Singh Memorial Hospital Lalitpur, Nepal. Methods: A total of 300 mid-stream urine, catheter and suprapubic aspirate from UTI suspected patients were included and processed for routine microscopy and culture and then identified by standard microbiological methods. Antibiotic susceptibility test was performed by Kirby- Bauer disc diffusion method. Results: Out of 300 samples, 55(84.6%) mid-stream urine and 10(15.4%) catheter sample had significant bacterial growth. E. coli (32,49.2%) was the most common isolate followed by Staphylococcus aureus (10,15.3%), Enterobacter spp. (8,12.3%), Klebsiella spp. (7,10.7%), Pseudomonas aeruginosa (3,4.6%), Proteus spp.  (3,4.6%), Acinetobacter spp. (1,1.5%) and Enterococcus spp. (1,1.5%). Most of the Gram-negative bacterial isolates were sensitive to Ceftriaxone (88.8%) followed by Gentamicin (72.2%), and Nitrofurantoin (64.8%) and resistant to Amoxicilin (68.5%) followed by Nalidixic Acid (53.7%). Gram positive isolates were sensitive to Amikacin (72.7%) followed by Imipenem (63.6%) and Gentamicin (63.6%) whereas resistant to Amoxycilin (72.7%) and Ciprofloxacin (63.63%). Conclusion: The main cause of the UTIs was found as Gram negative bacteria. Prescription of antibiotics based on susceptibility tests would help in reduction of antibiotic resistance.

Urinary tract infection is one of the most common bacterial infections seen in clinical practice both in developed and developing countries. The causative agents of Urinary tract infection vary from place to place and they also vary in their susceptibility and resistance patterns. This descriptive study aimed to evaluate the antibiotic susceptibility patterns of pathogens isolated from routine laboratory specimens at Dhaka Medical College Hospital. A descriptive cross- sectional study was done from January 2018 to June 2018. A total of 100 mid-stream urine samples from the suspected UTI patients were tested microbiologically and antimicrobial susceptibility test were performed for the isolated pathogens using Kirby-Bauer disk diffusion method with positivity rate of UTI was 90% (90/100). Escherichia coli (39%) was the most UTI causing bacteria followed by Klebsiella 18(18%), Acinetobacter 12(12%), Staphylococci, 9 (9%), Pseudomonas 6 (6%), Enterococcus species 3 (3%) and Proteus 3 (3%). Female 83 (83%) were more affected in comparison with male. Adult female especially age range 18-30 years were found in high risk. Nitrofurantoin, Amikacin and Meropenem were recorded as most sensitive antibiogram for most of the bacteria’s whereas cephalosporin showed increased resistance. However, for uncomplicated community acquired UTI, Nitrofurantoin (oral) and Amikacin (Injectable) can be chosen as first line medication. J MEDICINE JUL 2020; 21 (2) : 93-97

Urinary tract infection (UTI) is a common infection encountered by clinicians and despite the widespread availability of antimicrobial agents, UTI has become difficult to treat because of appearance pathogens with increasing resistance to antimicrobial agents. The objectives of this study were to determine the pathogens causing UTI and to determine the antibiotic sensitivity status among these isolates in a diagnostic laboratory in Dhaka city. A laboratory based cross sectional survey was conducted in a diagnostic Centre in Dhaka Bangladesh from July 2016 to December 2016. A total of 553 urine samples were collected from each patients and processed in microbiology laboratory to isolate pathogens and antibiotic susceptibility test using standard procedure. Among 553 urine samples, 158 (28.57%) samples was found to be culture positive of which 39 (24.70%) were isolated from male patients and 119 (75.30%) from female patients. Escherichia coli (43.67%) were found to be the predominant pathogen followed by Staphylococcus spp. (16.45%), Enterococcus spp. (13.39%), Klebsiella spp. (13.29%), Candida spp. (5.70%), Acinetobacter spp. (4.43%), Pseudomonas spp. (3.80%) and Proteus spp. (1.27%). The carbapenem group antibiotics (imipenem and meropenem) was found to be resistant in 0 to 5.1% of the Gram negative isolates. On the Other hand, most of the Gram positive isolates showed sensitivity to linezolid and vancomycin. This study showed that E. coli isolates were the predominant pathogens and showed resistance to commonly prescribed drugs resulting in a very few options for drug to treat UTIs.

The objective of the study is to assess the recent sensitivity pattern of Escherichia coli in Urinary tract infection (UTI). Widespread use of antibiotics has led to the emergence of resistant microorganisms. As the antibiotic sensitivity patterns of the microorganisms are frequently changing, this retrospective analysis was designed to assess the recent antibiotic sensitivity pattern of Escherichia coli (E. coli) in urinary tract infection among the human population. Details of 358 urine culture positive reports for E. coli and their antibiotic sensitivity pattern pertaining to the study period of 6 months from Jan 2017 to June 2017 were collected from Microbiology Laboratory of Diagnostic Centers at Rajshahi and the results were statistically analyzed. The antibiotics tested for sensitivity were amikacin, gentamycin, ciprofloxacin, levofloxacin, cotrimoxazole, nitrofurantoin, ceftazidime, ceftriaxone and cefixime. The sensitivity pattern of E.coli to antibiotics in UTI was amikacin (82.68 gentamycin (75.97%), nitrofurantoin (70.67), levofloxacin (44.13%), ceftazidime (42.17%), co-trimoxazole (40.78%), ceftriaxone (38.54%), ciprofloxacin (35.75%), and cefixime (24.02%). The study highlighted the marked resistance of E. coli to quinolones and third generation cephalosporins.TAJ 2017; 30(1): 61-65

Background and Objectives: Urinary tract infection (UTI) is one of the most frequent infectious diseases which is caused by Gram-negative bacteria especially Escherichia coli. Multiple resistance to antimicrobial agents are increasing quickly in E. coli isolates and may complicate therapeutic strategies for UTI. The propose of this study was to determine the antibiotic resistance patterns and the multidrug-resistance (MDR) phenotypes in uropathogenic E. coli (UPEC). Materials and Methods: A total of 153 UPEC isolates were collected from both hospitalized patients (95 isolates) and outpatients (58 isolates) from March to October 2018. In order to determine the MDR among UPEC isolates, we have tested 15 antimicrobial agents on Muller Hinton agar by the disk diffusion method. Results: The percentage of MDR isolates (resistant to at least three drug classes such as fluoroquinolones, penicillins and cephalosporins) was 55.5% in the hospitalized patients and the outpatients. Antibiotic resistance to ampicillin, ceftazidime, nalidixic acid and trimethoprim/ sulfamethoxazole was higher than 60%. Meropenem, Imipenem and norfloxacin indicated markedly greater activity (93.3%, 80% and 85.6%, respectively) than other antimicrobial agents. Conclusions: Urinary tract infection due to MDR E. coli may be difficult to treat empirically due to high resistance to commonly used antibiotics, so, empirical antibiotic treatment should be reviewed periodically at local studies.

Background: Urinary tract infection (UTI) is one of the commonest health problem encountered in clinical practice. The biofilms play major role in decreasing the susceptibility to the antimicrobial agents. The present study aimed at isolation and identification of Escherichia coli from cases of urinary tract infection, and to find out production of biofilms by these isolates and to correlate it with antimicrobial resistance.Methods: This study was a cross sectional study. Urine specimen from patients suspected of UTIs were collected and processed by standard operative procedure, antibiotic susceptibility test was done by Kirby Bauer disc diffusion method. Biofilm production in isolates was done by Tissue culture plate (TCP) method, Christensen’s test tube (CTT) method, and Congo red agar (CRA) method.Results: Out of the total of 250 isolates 191 (76%) showed biofilm positive by TCP method, 180 (72%) showed biofilm positive by CTT method, 161 (64%) showed biofilm positive by CRA method. 90% of total extended spectrum beta lactamase (ESBL) producing Escherichia coli were biofilm producers. There is more resistance for each and every antibiotic among biofilm producers in comparision to biofilm non producers.Conclusions: The microbial biofilms may pose a public health problem, as the microorganisms in the biofilms are difficult to be treated with antimicrobial agents.

Background : Urinary tract infection (UTI) is one of the most important causes of morbidity and mortality in the developing countries like Bangladesh. Antimicrobial agents are the frequently used drug for its treatment. Periodic evaluation of antimicrobial activity of different antibiotics is essential as the pattern of antibiotic sensitivity may vary over periods. Increasing antibiotic resistance among urinary pathogens to commonly prescribed drugs has become a global reality today.Objective : To determine the prevalence and to find out the causative agents of UTI and their antibiotic sensitivity pattern among suspected UTI patients attending Northern International Medical College Hospital (NIMCH), Dhaka.Methods : A retrospective study was conducted at Northern International Medical College Hospital, Dhaka, Bangladesh by analyzing the records of urine samples collected for culture and sensitivity tests over a period of six months (January 2014 to June 2014). Of the total 878 clean catch mid-stream urine samples collected from suspected cases of UTI patients of all ages and both sexes. Urine specimens were cultured for isolation of microbial agents of urinary tract infection. The isolated bacteria were identified using biochemical test. The diffusion susceptibility test was used to determine susceptibility of bacterial agents to antibiotics. Computerized data was collected from Microbiology department of NIMCH and analyzed by Microsoft Excel Version 2013.Results : In this study, 182 (20.73%) out of 878 urine sample were positive for pathogenic organisms. Of the various pathogenic organisms isolated, Escherichia coli constituted for 85.16% followed by Pseudomonas sp, Acinatobactersp, Group D Streptococcus, Staphylococcus aureus, Klebsiellasp, Enterobactersp and others. E.coli was found to be most sensitive to Imipenem, Amikacin and Meropenem and resistant to most commonly used oral drugs like Azithromycin, Cefexime, cotrimoxazole and Ciprofloxacin and Levofloxacin.Conclusion : Mainly Gram negative bacilli is responsible for UTI and most frequent isolated bacteria was E-coli. The most effective antibiotics were Imipenem, Amikacin, Meropenem,all of them are parentral. Majority E-coli were resistant to commonly used oral drugs like Azithromycin, Cefexime, cotrimoxazole and Ciprofloxacin. Therefore the choice of antibiotic therapy in UTI should be depends on the local sensitivity pattern of the infecting organisms.Northern International Medical College Journal Vol.7(1) Jul 2015: 105-109
