Acute Urinary Tract Infection

Urinary tract infection in children is still an important problem in uronephrology. The disease.tends to develop recurrently and results in chronic progressive renal disease in the future. Pipemidic acid is a bactericidal quinolone derivate, with a wide spectrum against gram positive and negative bacteria. Compared with nalidixic acid, pipemidic acid proves to be more effective against Pseudomonas, E. coli, Alkali genes and Salmonella. Thirty one cases with acute urinary tract infection had been studied descriptively. The etiology revealed as follows: E. coli (45.2%), Alkaligenes (16.2%), Enterobacter (9.6%), Staphylococcus (9.6%), Pseudomonas (9.6%), Paracolon (6,5%), and Proteus (3.3%). Pipemidic acid was administered orally to these patients, 15-20 mg/kg/day divided in 2 equal doses for 10 days. Bacteriological examinations was repeated on the 6th day and 11th day treatment. The result revealed that on the 6th day of treatment, in 27 patients (87, 09%) there was no bacteriuria while on the 11th  day the urine of 29 patients (93.54%) were sterile. In conclusion, a 5 day treatment of acute urinary tract infection in children with pipemidic acid is quite effective.

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.

Virulence Attenuation

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.

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.

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.
