Objectives: To investigate clinical characteristics, bacterial characteristics, drug resistance status in patients with urinary tract infections treated at Department of Urology, Hue University Hospital. Materials and Method: The study was conducted in 474 patients with urological disease treated at Department of Urology, Hue Universiry Hospital from July 2017 to April 2018. Urine culture was done in the patients with urine > 25 Leu/ul who have symptoms of urinary tract disease or infection symptoms. Patients with positive urine cultures were analyzed for clinical and bacterial characteristics. Results: 187/474 (39.5%) patients had symptoms associated with urinary tract infections. 85/474 (17.9%) patients were diagnosed with urinary tract infection. The positive urine culture rate was 45.5%. Symptoms of UTI were varied, and no prominent symptoms. E. coli accounts for the highest proportion (46.67%), followed by, Staphycoccus aureus (10.67%), Pseudomonas aeruginsa (8,0%), Streptococcus faecali and Proteus (2.67%). ESBL - producing E. coli was 69.23%, ESBL producing Enterobacter spp was 33.33%. Gram-negative bacteria are susceptible to meropenem, imipenem, amikacin while gram positive are vancomycin-sensitive. Conclusions: Clinical manifestations of urinary tract infections varied and its typical symptoms are unclear. E.coli is a common bacterium (46.67%). Isolated bacteria have a high rate of resistance to some common antibiotics especially the third generation cephalosporins and quinolones. Most bacteria are resistant to multiple antibiotics at the same time. Gram (+) bacteria are susceptible to vancomycin, and gram (-) bacteria are susceptible to cefoxitin, amikacin, and carbapenem.

ABSTRACTA mouse model of cystitis caused by uropathogenicEscherichia coliwas used to study the distribution of gallium in bladder tissue following oral administration of gallium maltolate during urinary tract infection. The median concentration of gallium in homogenized bladder tissue from infected mice was 1.93 μg/g after daily administration of gallium maltolate for 5 days. Synchrotron X-ray fluorescence imaging and X-ray absorption spectroscopy of bladder sections confirmed that gallium arrived at the transitional epithelium, a potential site of uropathogenicE. coliinfection. Gallium and iron were similarly but not identically distributed in the tissues, suggesting that at least some distribution mechanisms are not common between the two elements. The results of this study indicate that gallium maltolate may be a suitable candidate for further development as a novel antimicrobial therapy for urinary tract infections caused by uropathogenicE. coli.

Abstract Background: Urinary Tract Infection (UTI) is the most common bacterial infection in the world. E. coli is the predominant Pathogen. This study evaluates the prevalence of ESBL in E. colis isolated from patients with urinary tract infections with phenotypic and genotypic methods.Methods: This descriptive-analytical study was done on 155 isolates of E. coli isolated from patients with urinary tract infection who had received the study consent. After accurate identification of E. coli strains. ESBL production for Escherichia coli isolates which are resistant to ceftriaxone or ceftazidime was evaluated by CDT method. TEM, SHV and CTX-M genes were identified by PCR.Results: The results showed that 30 strains from 155 strains of E. coli had ESBL. Strains of ESBL producer were more in males was lower in educated persons. 38.9% of ESBL producer had antibiotic use, 29.9% -producing Escherichia hospitalization and 31.6% uti history. The highest level of drug allergy in the ESBL was related to nitrofurantoin, and the highest resistance was related to cefazolin, co-trimoxazole. The CTX-M and the CTX-M15 gene were found in 92.7% and 57.1% of cases, respectively; also the SHV and TEM genes were not found in any of ESBL-producing Escherichia coli strains. Most therapeutic response in patients was related to cefexime, ciprofloxacin and nitrofurantoin 27.4%, 26% 21.9%, respectively.Conclusion: This study showed that the history of antibiotic use, hospitalization, uti related to increase of ESBL-producing in E. coli isolates., the CTMX-M gene is the most common gene in ESBL-producing E. coli strains.

Urinary tract infection remains a major public health problem in developing countries, where there are limited health-care services. Its prevalence is fueled by human immunodeficiency virus (HIV) infection. The emergence of antimicrobial resistance is now widespread and poses a serious clinical threat. This study investigated the prevalence, antimicrobial susceptibility pattern of bacterial isolates, and associated factors of urinary tract infections among HIV-positive adult patients. A cross-sectional study was conducted among 350 randomly selected HIV-positive patients at Hiwot Fana Specialized University Hospital from February to March 2016. Data were collected using a structured questionnaire. Clean-catch midstream urine samples were collected aseptically and examined using the recommended culture methods. Antimicrobial susceptibility testing was performed using the Kirby–Bauer disk diffusion technique. Data were analyzed using Statistical Package for the Social Sciences version 21.0. The logistic regression models were used to explore the predictors of the outcome. A p value < 0.05 was considered statistically significant. The overall prevalence of urinary tract infection was 18% (95% CI: 15.34–22.63). Individuals with age 35–44 years (Adjusted odds ratio (AOR): 4.07; 95% CI: 1.09, 5.10), income less than 46.7 USD (AOR: 2.76; 95% CI: 1.15, 6.07), and a CD4+ count less than 200 cells/mm3 (AOR: 2.07; 95% CI: 1.15, 3.73) had higher odds of UTI. Escherichia coli (38.1%), Klebsiella pneumoniae (23.8%), and Staphylococcus aureus (11.1%) were the predominant causes of urinary tract infection. E. coli was resistant to ampicillin (95.8%), ceftazidime (95.8%), cotrimoxazole (95.8%), amoxicillin (91.7%), ceftriaxone (87.5%), and tetracycline (87.2%). Multidrug resistance was observed in 46% of the isolates. The prevalence of urinary tract infection in this study was high compared to the previous reports in Ethiopia. Age 35–44 years, income less than 46.7 USD, and a CD4+ count < 200 cells/mm3 increase the odds of urinary tract infection. The most common isolates were E. coli, K. pneumoniae, and S. aureus. Almost half of the isolates were multidrug resistant. Actions to help mitigate the further spread of resistance are urgently needed in the study area.

Escherichia coli (E. coli) is the most common type of pathogen that causes Urinary tract infection disease. It can be presented as a pathogenic or non-pathogenic strain and found not only in the animal but also in the human intestine. This bacterium can cause opportunistic infection when the human host comprised of thalassemia patients or changes the healthy hemostatic flora. This study aimed to analyze the presence of bacteria in thalassemia patients with urinary tract infection. A total of 303 samples were collected during the period from August 2019 to January 2020 from thalassemia patients who suffered from urinary tract infection. The results showed that there were 6.9% of patients infected with E. coli, 2.6% of patients were infected with S. aureus, 0.7% with both Proteus and Klebsiella, while 89.1% of patients had a negative sample for bacteria. Also, the incidence of urinary tract infections in females is higher than in males. Besides, its occurrence in rural areas is higher than in city residents. Moreover, among 16 antibiotics tested to sensitize bacteria to antibiotics, Imipenem showed 100% efficacy on all isolated bacteria. In contrast, Netilmicin showed 80.1% efficacy, Gentamycin 80.1%, and Amikacin 76.2%. Ampicillin, Aztreonam, Amoxicillin-Clavulanic Acid, Tetracycline, and Ticarcillin-Clavulanic Acid, did not show any effectiveness toward the bacteria while other antibiotics showed different activities. Furthermore, the isolated microbes from thalassemia patients were the highest resistance to antibiotics in comparison with other studies, and this antibiotic-resistant may be due to the weakening of the patient's immune status and frequent blood taking and the antibodies it contains.

Background: Escherichia coli is considered as one of the causes of opportunistic infections. Nowadays, due to the increase in drug resistance, the treatment of these infections has become very difficult and they are recognized as the main causes of death in hospitalized patients. Objectives: The aim of this study was to determine the prevalence of blaTEM, blaSHV, and blaCTX-M genes in E. coli strains isolated from the urinary tract infection in patients in Intensive Care Units of three different hospitals in Qom, Iran. Methods: This study was conducted in three months from October to December 2014. A total of 200 E. coli samples were taken from the patients with urinary tract infections in Intensive Care units of Qom hospital. The disc diffusion method was used to determine the susceptibility pattern of antibiotic and phenotypic confirmatory tests for screening of the expanded spectrum beta-lactamase (ESBL) isolates. The presence of blaTEM, blaSHV, and blaCTX-M genes was evaluated by the polymerase chain reaction (PCR) assay. Results: Of 200 samples, ampicillin (96%) and nitrofurantoin (19.5%) showed the highest and lowest drug resistance, respectively. A total of 156 isolates (78%) were identified as ESBLs using the phenotypic method. Moreover, 76 (38%), 90 (45%), and 123 (61.5%) isolates consisted of blaCTX-M, blaSHV, and blaTEM, respectively. Conclusions: Overall, the findings of this study showed that blaTEM was the most common gene with a frequency of 61.5% in ESBL E. coli.

Urinary tract infection mainly occurs by microorganism when they overcome the human immune system. These microbes have caused the high rate of morbidity and motility effect all over the world to every age and gender. Lower urinary tract infection is more common among females than males. A prospective observational study was conducted in Pathology Department at Lady Reading Hospital Medical Teaching Institution, Peshawar, Pakistan in a 4th quarter (October, November, December) of the year 2017. Mid-stream urine samples were collected from 1357 patients from all hospital-admitted and outdoor patients. They were cultured on CLED agar, after isolation, uropathogens was identified through biochemical tests like oxidase, catalase and TSI tests. Only 205 samples were reported positive, with the prevalence of 15.10%. Females (51.70%) were more prone to UTI then males (48.29%). E.coli was most frequently isolated uropathogen with frequency of 90.24%. Other isolates were Pseudomonas aeruginosa (4.8%), Enterococcus faecium (2.92%), Enterobacter species (1.46%) and Proteus mirabilis (0.49%). Thirteen antibiotics were used to test the susceptibility of isolated microbes through Kirby Bauer Disc Diffusion method. Carbapenem drug like Imipenem (89.7%) was most effective against gram-negative microbes belonging to Enterobacteriaceae family. Other antibiotics like, Piperacillin + Tazobactam (84.86%), Cefoperazone /Sulbactam (84.3%), Amikacin (84.3%), Fosfomycin (83.7%) and Nitrofurantoin (77.2%) also showed sensitivity. Fluoroquinolones Drugs like Ciprofloxacin (82.1%) and Levofloxacin (81.6%) showed high resistivity followed by Co-trimoxazole (80.54%) and Cephalosporine drugs. For Gram positive Enterococcus spp, Glycopeptide antibiotics and protein synthesis inhibitor drugs had shown 100% sensitivity, but carbapenem and fluoroquinolones were highly resistant.

AbstractIntroduction: In pediatrics, the urinary tract infection is one of the most frequent bacterial infection, representing an important health problem due to its high incidence, wide etiology, asymptomatic evolution, and multiple and sever complications, relapses and sequelae.” Material and Method: We evaluated 45 children, aged between 6 months and 16 years, diagnosed and treated for urinary tract infection at the Clinical Infectious Diseases Hospital, of Constanta County, in a period of 3 years and 6 months. Results: During studied period, between January 2014 and June 2017 from a total of 9343 patients admitted to the Constanta Clinical Infectious Diseases Hospital, we selected 45 children (4.81‰) diagnosed with urinary tract infection. The average age of children with urinary tract infections was 5 years and 5 months. The gender distribution revealed a 2:1 balance in girl’s favor. The most affected group of age was 1-3 years. Fever was the dominating symptom. Urine cultures were positive for 37 cases, meanwhile for eight cases had been negative. The predominant germs are E. coli for female and for male Proteus. We noticed that for E. coli the highest sensitivity is preserved to Ertapenem -15 cases, followed by Ceftriaxone and Ciprofloxacin -10 cases each, and Gentamycin -9 cases. Conclusions: Pediatric urinary tract infection should be considered in every patient under 3 years with unexplained fever.

INTRODUCTION: Urinary tract infection (UTI) is considered as the most common bacterial infectious disease seen among the pediatric patients. Most commonly, members of Enterobacteriaceae, particularly uropathogenic strains of E. coli and Enterobacter spp. are the primary causative pathogens of UTI in the different part of the world. Emergence of antimicrobial resistance rates among pathogens recovered from urinary tract infections is an increasing problem in the specific region. MATERIALS AND METHODS: Prevalence and anti microbial susceptibility pattern of the bacterial uropathogens isolated from the children attending Gandaki Medical College Teaching Hospital and Reserch Center (GMC) Nepal. A total of 155 children aged upto 15 years were included in this study. Urine cultures were carried out and the isolates were identified by Gram staining and conventional biochemical methods. Antimicrobial susceptibility testing was performed by disk diffusion method according to the Clinical and Laboratory Standards Institute (CLSI). RESULTS: In the present study 21.3 % of the sample size, showed significant bacterial growth. E. coli was the most frequently occurring pathogen (39.40%), followed by Proteus spp. 21.2%, Citrobacter spp. and Streptococcus faecalis (12.1%) Klebsiella spp. (9.1%), and Staphylococcus aureus and Enterobacter (3.0%). Susceptibility rate of E. coli were 69.2% to Gentamycin and Amikacin, 53.8% to Norfloxacin, 38.4% to Nalidixic acid and Norfloxacin. CONCLUSIONS: Pediatric urine culture isolates were becoming increasingly resistant to commonly used antibiotics. Finally, we suggest that empirical antibiotic selection should be based on knowledge of the local prevalence of bacterial organisms and antibiotic sensitivities rather than on universal guidelines.
