scholarly journals Isolation and Identification of Microbes on Hands and Mobile Phones Causing Urinary Tract Infections

Background: Hands and cell phones are the major source of cross-transmission of urinary tract infections. The aim of this study was to isolate, identify and evaluate Gram-negative bacteria from hand and mobile phones. Methods: This study was conducted in visiting area of Civil Hospital Karachi, Pakistan. Analysis was done by 100 wet sterile cotton tipped swabs, 50 each from mobile phones and hands of their owners. Samples were transported in a Cary Blair transport media, Swabs were streaked on Nutrient agar, Blood agar and MacConkey agar. Organisms were identified by cultural, biochemical, and microscopic characteristics. Results: Total samples n=100 was collected from hand and mobile phones samples (50 hand and 50 mobile swabs) from the Dow university Hospital and Civil Hospital Karachi were tested. Six species of bacteria were isolated along with their identification during the research study. The isolated bacteria were Serratia, Klebsiella, Pseudomonas, Proteus, Shigella and Escherichia coli. The participants’ hands showed high bacterial contamination (50%-56%) in comparison to mobile phones. The frequency (%) of bacteria isolated from mobile phone and hand swabs included Serratia, 12 (24%) with the highest quantity and frequently found bacteria. While, the rest of the results reported Escherichia coli 10 (20%), Klebsiella 9 (18%), Pseudomonas 5 (10%), Shigella 4 (8%) and Proteus 10 (20%) respectively. Conclusion: Patient attendants in hospitals and visitors are more susceptible to nosocomial infections through exchange of mobile phones n=12(24%). Therefore, hygienic practice of hands cleaning while mobile using may help to break the transmission cycle of pathogenic bacteria.

Introduction: The frequency of Enterobacteriaceae involved in urinary tract infections (UTI) has increased significantly since the early 1990s, particularly in at-risk facilities such as resuscitation, surgery, urology and nephrology. The objective of this study was to evaluate the antimicrobial susceptibility of Enterobacteriaceae causing urinary tract infections (UTIs)at the University Hospital Centre of Benimessous in Algiers. Methodology: The study was designed as a retrospective study (between January 1st 2010 and December 31st 2012) and a prospective study (between January 1standApril 30th 2013) on 13,611 urine samples. Antimicrobial resistance phenotyping was conducted on the bacterial isolates using disk-diffusion method. Results: On 13,611 urine samples analysed, 1,790 (13.15%) fulfilled the criteria for urinary tract infection. Enterobacteriaceae were identified in 1,561 analysed samples (87%). Escherichia coli was the dominant uropathogen (66,15%) in both hospitalized and non-hospitalized patients. The other main detected Enterobacteriaceae members were Klebsiella pneumoniae (11,96%) and Proteus mirabilis (5,42%). Analysis of results showed also that women were more prone to UTI than men with sex ratio of 3.76(W/M). The susceptibilities of isolated Enterobacteriaceae to antibiotics revealed that they had acquired resistance to several classes, particularly toward β-lactams. Resistance frequencies were relatively high to ampicillin and sulfomethoxasole, while being very low to aminoglycosides and furans. Results obtained revealed also that 7% of isolates where resistant to third generation cephalosporins by production of extended spectrum β-lactamases (ESBL). Conclusions: The continuous monitoring of antibiotic resistance of uropathogenic Escherichia coli is crucial to guide the clinician to choose the best empiric treatment.

Background: Urinary tract infection is a common pathology during pregnancy due to hormonal and morphological changes. Objective of this study was to improve management of urinary tract infection during prenatal care.Methods: A total of 987 pregnant women who have been in prenatal care have freely accepted to participate in cross-sectional study carried out from 1st May 2016 to 30th April 2017 at Yopougon University Hospital (Abidjan Côte d’Ivoire) were included. Patients were submitted to questionnaire by one of investigators for epidemiological component and then physical examination was carried out by her attending physician for clinical component. Then at laboratory urine was taken for culture after dipstick test.Results: Of the 987 patients included 9.4% had a urinary tract infection of which 81.7% were asymptomatic. Significant risk factors retained were existence of a history of urinary tract infection (OR=0.46; p=0,038) and gestational age of pregnancy (OR=0.44; p=0.05). Urine culture isolated germs were mainly Escherichia Coli (51.6%) and Klebsiella pneumoniaie (23.6%). These germs were all susceptible to cephalosporins. They had resistances of more than 50% to penicillins.Conclusions: Escherichia coli and Klebsiella pneumoniae are most common germs of urinary tract infections in pregnant women. Escherichia coli is not susceptible to penicillins with a resistance of 70% for penicillins except for clavulanic acid amoxicillin. It appears as first choice antibiotic for our prescriptions in case of probabilistic antibiotic therapy.

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. Key words: urinary tract infection

Introduction: The aim of the current study was to investigate the prevalence of virulence genes in uropathogenic Escherichia coli (UPEC) isolates in Ilam. Materials and Methods: For this purpose, a total of 80 UPEC isolates were collected for patients with UTIs during a 6 months period. The multiplex polymerase chain reaction (multiplex PCR) was used to detect the papEF, fimH, iucD, hlyA, fyuA, and ompT genes. Results: The prevalence of fimH, papEF, iucD, fyuA, hlyA, hlyA, and ompT genes were 87.5%, 47.5%, 60%, 67.5%, 27.5%, 47.5% and 71.2%, respectively. Among all of the isolates, 27 profiles were obtained. Conclusion: Our findings demonstrated that the most prevalence was found for fimH, and different distribution of virulence genes suggested different ability of pathogenicity.

ABSTRACT In a randomized crossover study, 16 volunteers (8 men, 8 women) received single oral doses of 320 mg of gemifloxacin and 400 mg of ofloxacin on two separate occasions in the fasting state to assess the urinary excretion and urinary bactericidal titers (UBTs) at intervals for up to 144 h. Ofloxacin showed higher concentrations in urine compared with those of gemifloxacin. The median (range) cumulative excretion of gemifloxacin was 29.7% (8.4 to 48.7%) of the parent drug administered, and median (range) cumulative excretion of ofloxacin was 84.3% (46.5 to 95.2%) of the parent drug administered. The UBTs, i.e., the highest twofold dilutions (with antibiotic-free urine as the diluent) of urine that were still bactericidal, were determined for a reference strain and nine uropathogens for which the MICs of gemifloxacin and ofloxacin were as follows:Escherichia coli ATCC 25922, 0.016 and 0.06 μg/ml, respectively; Klebsiella pneumoniae, 0.03 and 0.06 μg/ml, respectively; Proteus mirabilis, 0.125 and 0.125 μg/ml, respectively; Escherichia coli, 0.06 and 0.5 μg/ml, respectively; Pseudomonas aeruginosa, 1 and 4 μg/ml, respectively; Staphylococcus aureus, 0.008 and 0.25 μg/ml, respectively; Enterococcus faecalis, 0.06 and 2 μg/ml, respectively;Staphylococcus aureus, 0.25 and 4 μg/ml, respectively;Enterococcus faecalis, 0.5 and 32 μg/ml, respectively; and Staphylococcus aureus, 2 and 32 μg/ml, respectively. Generally, the UBTs for gram-positive uropathogens were higher for gemifloxacin than for ofloxacin and the UBTs for gram-negative uropathogens were higher for ofloxacin than for gemifloxacin. According to the UBTs, ofloxacin-resistant uropathogens (MICs, ≥4 mg/liter) should also be considered gemifloxacin resistant. Although clinical trials have shown that gemifloxacin is effective for the treatment of uncomplicated urinary tract infections, whether an oral dosage of 320 mg of gemifloxacin once daily is also adequate for the treatment of complicated urinary tract infections has yet to be confirmed.
