Introduction: Urinary Tract Infection (UTI) is one of the most common bacterial diseases worldwide that can present as asymptomatic or symptomatic characterized by a wide range of symptoms from mild irritative voiding to bacteremia, sepsis or even death. Increase in resistance of urinary pathogens to conventional antimicrobial agents is gaining the attention of many microbiologists worldwide in respect to treatment of urinary tract infection. Since the pattern of bacterial resistance is continuously changing, the monitoring of antibiotic susceptibility pattern becomes more important.Objective: The objective of this study was to update the distribution of current urinary pathogens and to find out their antimicrobial susceptibility pattern.Methods: A Cross sectional descriptive study was conducted at Border Guard Hospital (BGB Hospital) Peelkhana, Dhaka during the period of February 2013 to September 2013. A total of three hundred ninety urine samples were collected from patients with suspected UTI. All the samples were clean catch mid stream urine. Urine samples were cultured on MacConkey agar medium and blood agar medium. Colony counts yielding single type of bacterial growth of 105 CFU/ml were deemed significant.Results: Out of 390 samples, 49(12.56%) samples were culture positive. The isolated organisms were identified by conventional methods and were subjected to determine antimicrobial susceptibility testing by Kirby Bauer’s disc diffusion method. Escherichia coli (E.coli) was found as the most prevalent isolates 31(63.26%) followed by klebsiella spp 06(12.24%), Enterobacter spp o4(8.17%), Pseudomonas aeruginosa 04(8.17%), Staphylococcus aureus (Staph aureus) 02(4.08%) and Enterococcus spp 02(4.08%). Eight antimicrobial agents namely Amoxycillin, Co-trimoxazole, Levofloxacin, Nitrofurantoin, Gentamicin, Ceftriaxone, Imipenem and Amikacin were used for antimicrobial susceptibility testing. The most effective drug found against urinary isolates was Imipenem (95.91%), followed by Amikacin (81.63%) and Ceftriaxone (69.38%). None of the drug found was 100% effective against urinary pathogens. E.coli was found to be fairly sensitive to Ceftriaxone, Gentamicin and Nitrofurantoin.Conclusion: Urinary tract infection remains one of the most common bacterial infections. Antimicrobial drug resistance is increasing among urinary pathogens. This study updated the current occurrence of urinary pathogens and their antibiotic sensitivity pattern. We recommend periodical determination of antimicrobial sensitivity pattern of urinary pathogens in a particular hospital or area.Journal of Armed Forces Medical College Bangladesh Vol.10(2) 2014

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.

Correction: On 10th August 2017 due to typographical errors, the period of the study was changed from May 2016 to June 2017 and the caption of the red segment in Figure 1 was changed from No UTI, 41% to UTI, 59%Background: Urinary tract infection (UTI) is one of the common bacterial infections in mankind. The changing antimicrobial sensitivity in UTI demands use of appropriate antibiotics.Objective: This study was conducted to determine the distribution and antimicrobial susceptibility of uropathogens.Materials and method: This was a prospective study conducted in Bangladesh Medical College & Hospital, Dhaka, Bangladesh between May 2016 and June 2017 to identify the organisms causing UTI and their antibiotic susceptibility. Clean catch midstream urine samples were collected from 95 patients presenting with symptoms of UTI. Antimicrobial susceptibility was performed by disc diffusion method.Results: Out of 95 urine samples, 56 (58.9%) were found positive. The prevalence was significantly higher in females than in males (females: 58.9%; males: 41%). Age group of >48 years showed higher prevalence of UTI. The most common organisms isolated were Escherichia coli, Klebsiella, Pseudomonas, Proteus and Staphylococcus aureus. These represented 44.6%, 21.4%, 14.3%, 12.5%, and 7.14% of isolates respectively. Imipenem and Meropenem were found the most susceptible drug against isolated uropathogens.Conclusion: Most powerful antibiotics in our study were imipenem and meropenem. In conclusion, one can truly affirm that the choice of drugs in the treatment of UTI is becoming quite narrow today due to the wide scale resistance that the common UTI pathogens show to drugs which have been used previously.Delta Med Col J.

   Urinary tract infection is the most common infection in females worldwide. One in three women experiences at least one episode of urinary tract infection during their lifetime. The objective of this study was to determine the etiology and antimicrobial profile of urinary tract infection. A cross-sectional study was conducted at a tertiary care hospital in Nepal. Thirteen hundred clean catch mid-stream urine samples were tested through standard microbiological techniques. The isolates from urine samples were identified from biochemical tests. Antibiotic susceptibility testing was performed through the Kirby-Bauer disc diffusion technique following CLSI guidelines. The prevalence of urinary tract infection was found at 24.23%. Escherichia Coli was a predominant etiological agent followed by Staphylococcus aureus. The majority of the infection was found between the age group 21-40, with females mostly infected. Most of the microorganisms were isolated from emtergency, obstetrics-gynecology, and nephrology wards. Most of the isolates were resistant to ampicillin, whereas the majority of the gram-positive isolates were resistant to penicillin.A large number of isolates were found to be sensitive to Gentamycin and nitrofurantoin. Routine antimicrobial susceptibility testing of the isolates causing urinary tract infection is recommended to reduce antimicrobial resistance and for the  proper treatment of infection.

Abstract Back ground: Urinary tract infection are one of the most common bacterial infections in the community and in the hospital. Nowadays, little is known about the status of community and hospital acquired urinary tract infection, antimicrobial susceptibility pattern and associated factors among urinary tract infection patients in Ethiopia, particularly in our study area. Methods A hospital based cross sectional study was carried out in Dessie referral hospital. A total of 422 urine samples were enrolled using systematic random sampling technique. All isolates were identified by standard microbiological techniques and their antibiotic susceptibility was done by Kirby Bauer disc diffusion method. Data was entered using Epi data version 3.1 and analyzed by SPSS software version 20. P- Value < 0.05 at 95% CI was considered as statistically significant. Result Of 422 urine samples processed 100 (23.7%) yielded bacterial isolates. About50(30.7%) and 50(19.3%) samples from hospitalized and community showed significant bacteriuria respectively. E. coli 44/103(42.7%), predominated across the two groups followed by S. aureus 25/103(24.3%), CONs,14/103(13.5%), Klebsiella spps 7/103(6.78), proteus spps 3/103(2.91), and Entrococcus spps 3/103 (2.91%). Pseudomonas spps 3/103 (2.91), Citrobacter spps 2/103(1.94%) and Acinetobacter Spp 1/103(0.999), which were isolated from only the hospitalized samples. Meropenem susceptibly was 100% in both study groups and Ampicillin resistance was documented as 83.3–100% and 76.9–100% in hospitalized and community acquired respectively. Among risk factors previous use of antibiotics, female gender, Age, Diabetics, catheterization were associated with the infection. Conclusion The present study revealed that slightly high prevalence of urinary tract infection. High antimicrobial resistance was observed to most antimicrobial drugs tested. Meropenem and Nitrofurantoin were the most active drugs for urinary tract infection. Empirical selection of antimicrobial agents should be based on antibiotic sensitivity pattern of uropathogens that prevalent in that area. Female sex, age, previous use of antibiotics, catheterization and diabetics were at risk of urinary tract infection.

Background: The genus Enterococcus is of increasing significance as a cause of nosocomial infections and this trend is exacerbated by the development of antibiotic resistance.Objective: The aims of this study was to find out the susceptibility pattern and the prevalence of virulence genes in Enterococcus strains isolated from urinary tract infection in Bangladesh.Methodology: This cross-sectional study was conducted in the Department of Microbiology at Dhaka Medical College, Dhaka from January 2015 to December 2015 for a period of one (01) years. All the admitted patients in the Dhaka Medical College & Hospital, Dhaka and Banghabandhu Sheikh Mujib Medical University, Dhaka who were  presented with clinical features of urinary tract infection at any age with both sexes were included as study population. The antimicrobial susceptibility of the strains was determined using the disk diffusion method; vancomycin susceptibility pattern was detected by MIC method. PCR was performed for the detection of genus-species, vanA, vanB gene and potential virulence genes.Result: Out of 84 Enterococci, majority (71.42%) of the isolates were E. faecalis followed by 23.81% were E. faecium. Regarding antimicrobial susceptibility pattern, 100% isolated Enterococci were sensitive to vancomycin, linezolid and teicoplanin. Most of the Enterococci were resistant to ciprofloxacin and ceftriaxone (92.86%) followed by 88.10% to gentamicin and 85.71% to azithromycin and rifampicin. No VRE was identified and the range of MIC for vancomycin was 1-4 µg/ml. None of the Enterococci was positive for vanA and vanB genes. Out of total E. faecalis and E. faecium, 87.50% were positive for ebp and 77.5%, 72.5%, 55.0%, 45.0%, 40.0% and 10.0% of isolates were positive for gelE, esp, ace, cyl, asa and hyl respectively.Conclusion: Almost all the virulence genes were more prevalent in E. faecalis isolates.Bangladesh Journal of Infectious Diseases 2017;4(2):30-34

Urinary tract infections represents one of the most common diseases encountered in medical practice affecting people of all ages from the neonate to the geriatric age group. The aim of this study was to determine and evaluate the antimicrobial susceptibility patterns for most common strains of bacterial urine isolates taken from patients at Azadi teaching hospital laboratories in Duhok city/Kurdistan region in Iraq, for two years (2014 and 2015). A retrospective survey study was conducted and 1003 data of urine culture sensitivity test were collected from recorded archives of the Azadi hospital of two years; 2014 and 2015.  The study included all recorded positive urine samples cultures isolated from inpatients and outpatients. Results revealed that the female to male ratio for urinary tract infection was 2.7:1 and the most common microorganisms isolated were Escherichia coli (52%), Staphylococcus aureus (11%), Staphylococcus haemolyticus (9.6%) and Klebsiella pneumoniae (8.1%). In general maximum sensitivity was seen for Meropenem (94.9%), followed by Imipenem (89.7%) and Ertapenem (88.7%). The maximum resistance was seen against Cefazolin (79.7%) and Amoxicillin/clavulanic acid (77.5%). The antibiotic sensitivity pattern of E. coli reveals that the maximum sensitivity was seen for Meropenem (97.3%) and Imipenem (95.6%). The maximum resistance was seen against Amoxicillin/clavlanic acid (83.1%). The resistance against many commonly used antibiotics have been increased which limit the options for treating urinary tract infection. This is resulted from uncontrolled use of the antibiotics and lack of policies and guidelines for their use in public health.

Background: Urinary tract infection (UTI) is a common cause of hospital visits. There is an increasing trend of resistance of uropathogens to antibiotics worldwide. The aim of this study was to identify the common uropathogens, along with their antimicrobial susceptibility. Methods: This retrospective cross-sectional study was conducted from April 2018 to April 2020 at Beni hospital. All patients with urinary tract infection visiting Beni hospital during this time and who had urine culture sensitivity tests done were included in this study. Urine samples were first cultured on cystine lactose electrolyte-deficient agar by a semi-quantitative technique, and then incubated aerobically for 18–24 h at 37 °C. The identified bacterial isolates were tested for antimicrobial susceptibility by the Kirby–Bauer disc diffusion technique. Results: Of the 1173 samples, 164 (14%) samples showed significant growth. Escherichia coli (74%) was the most common causative organism. E. coli was sensitive in 113 cases (95%) out of 119. Amikacin was tested in 87 isolates that showed 99% sensitivity. Other commonly used antimicrobial agents had lower sensitivity rates: gentamicin (83%), ciprofloxacin (75%), ceftriaxone (59%), cefixime (56%), cotrimoxazole (55%), cefotaxime (41%), and ampicillin (38%). Conclusions: E.coli is the most common pathogen associated with urinary tract infection. Nitrofurantoin and amikacin can be good empirical agents for treating UTI in patients coming to Beni hospital.
