In a premature infant nursery 3 infants died of E. coli infections and 5 babies contracted urinary tract infection due to E. coli within a 5-month period. The causative organisms were found to be resistant to tetracycline, streptomycin, chloramphenicol, and sulfisoxazole, and sensitive to kanamycin, polymyxin B, and nitrofurantoin. From throat and stool cultures of 25 infants in the nursery, E. coli with this susceptibility pattern were recovered from 13. Of these, 9 were serotype 04:H5 and one was group 04 but nonmotile. Isolates from the urine of 3 infants with urinary tract infection and meninges of one fatal case were serotype 04:H5. Stool cultures revealed group 04 E. coli only in infants with that organism in the throat. The findings indicate that an outbreak of infections due to E. coli 04:H5 had occurred as a consequence of widespread colonization with that organism in a premature infant nursery. The unusual incidence of urinary tract infection due to a specific E. coli serotype indicates that urosepsis in the newborn can occur in epidemic form.

Objective: This work aimed to detect the antibiotic susceptibility pattern of Escherichia coli isolated from children, as it is the most predominant pathogen of urinary tract infection (UTI). Methods: About 530 urine samples were collected and tested using the modified Kirby–Bauer disk diffusion method to find the susceptibility pattern of isolated bacteria. Results: Out of a total of 530 samples, 114 (21.50%) showed significant growth. A total of 8 different types of bacteria were isolated from the growth of positive samples. Among the isolates, E. coli 66 (57.8%) was found to be the most predominant organism followed by Klebsiella pneumoniae 18(15.8%), Proteus spp. 10 (8.8%), Staphylococcus aureus 8 (7.0%), Acinetobacter spp. 4 (3.5%), CoNS 4 (3.5%), Enterobacter spp. 2 (1.8%), and Pseudomonas aeruginosa 2 (1.8%). In the present study, out of 66 E. coli, 37 (56.1%) were multidrug-resistant strain. E. coli showed 94.0% resistance to ceftriaxone followed by ceftazidime 86.5% and cefotaxime 70.3%. Imipenem (91.9%) followed by amikacin (89.2%) seems to be the effective drug against UTI causing E. coli in children. Conclusion: Multidrug resistance may possess difficulties with the choice of therapeutic options for the treatment of severe infections.

Background: Urinary tract infection (UTI) is the most common bacterial infection, it causes morbidity as well as financial burden. There is a role of empirical treatment of UTI while awaiting urine culture and sensitivity result. The type of empirical antibiotics given varies from place to place depending on susceptibility pattern of the particular area. According to Tanzania standard treatment guidelines and essential medicine list of 2013, cystitis in adult is treated by ciprofloxacin while pregnant women and children are treated by amoxicillin/clavulanate. In case of pyelonephritis, women of reproductive age who does not require referral are treated by ciprofloxacin while all other cases that fulfill criteria for referral are given single dose of ceftriaxone before referral. However, most studies have shown increasing resistance to commonly used antibiotics as a result of misuse and overuse. The study aimed at describing the microbiological profile and susceptibility pattern among patients with UTI at KCMC. Methods: This was a seven-month hospital based descriptive, cross-sectional study conducted from June 2016 to December 2016 by using structured data extraction sheet. Data analysis was performed using SPSS after cleaning and checking for error(s). Results: A total of 270 samples that tested positive for UTI were analyzed. Majority 233(86.3%) of the sample were obtained from male subjects, age of study subjects ranged from 1-94 years with the median of 64 years. Majority 235 (87%) of the sample came from urology department with E. coli being most common cause of UTI (39.3%), followed by Klebsiella spp, 20%. E. coli demonstrated high sensitivity against amikacin, ceftazidime and Nitrofurantoin Conclusion: The commonest cause of UTI in our set up is E. coli that showed high resistance against most commonly used antibiotics in our setting.

A total of 27 isolates from patients with urinary tract infection (UTI) were screened and of these 12 were found to be Escherichia coli. All the E. coli isolates were multidrug resistant. Among the antibiotics, imipenem and polymyxin B were found to be the best, while oxacillin, cefsulodine and methicillin proved to be worst in effectiveness against the studied E. coli isolates. Only 42% of the E. coli were susceptible to trimethoprim-sulfamethoxazole (TMP–SMX), the current drug of choice for treating UTI. Middle ranged plasmids were observed in the studied isolates. Five strains expressed curli fimbriae and two elaborated cellulose; two other strains produced both curli and cellulose as extracellular matrix component.

Background: Antibiotic resistance emerged as clinical problem challenge the effective treatment of infections. Virulence factor may play an important role in the influence of antimicrobial resistance. Objective: To determine the frequency of resistance gene in E. coli clinical isolates from women with urinary tract infection. Materials and Methods: Fifteen E.coli clinical isolates were tested by PCR to determine their molecular characterization. Results: The bla CTX –M gene was not detected in 6.7% out of the tested 15 E. coli clinical isolates from women with urinary tract infection. However, bla OXA gene was detected in all E. coli tested clinical isolates from pregnant women, female student and diabetic women with urinary tract infection. While bla TEM gene and bla SHV gene were not detected in 33.3% and 40% out of the tested E. coli clinical isolates respectively. Conclusions: Four types of ESBL genes were detected, and shows new trend of distribution, which indicated the predominance of OXA and CTX-M genes.

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.

ABSTRACT Extraintestinal Escherichia coli strains cause meningitis, sepsis, urinary tract infection, and other infections outside the bowel. We examined here extraintestinal E. coli strain CFT073 by differential fluorescence induction. Pools of CFT073 clones carrying a CFT073 genomic fragment library in a promoterless gfp vector were inoculated intraperitoneally into mice; bacteria were recovered by lavage 6 h later and then subjected to fluorescence-activated cell sorting. Eleven promoters were found to be active in the mouse but not in Luria-Bertani (LB) broth culture. Three are linked to genes for enterobactin, aerobactin, and yersiniabactin. Three others are linked to the metabolic genes metA, gltB, and sucA, and another was linked to iha, a possible adhesin. Three lie before open reading frames of unknown function. One promoter is associated with degS, an inner membrane protease. Mutants of the in vivo-induced loci were tested in competition with the wild type in mouse peritonitis. Of the mutants tested, only CFT073 degS was found to be attenuated in peritoneal and in urinary tract infection, with virulence restored by complementation. CFT073 degS shows growth similar to that of the wild type at 37°C but is impaired at 43°C or in 3% ethanol LB broth at 37°C. Compared to the wild type, the mutant shows similar serum survival, motility, hemolysis, erythrocyte agglutination, and tolerance to oxidative stress. It also has the same lipopolysaccharide appearance on a silver-stained gel. The basis for the virulence attenuation is unclear, but because DegS is needed for σE activity, our findings implicate σE and its regulon in E. coli extraintestinal pathogenesis.
