ABSTRACT Studies were conducted to characterize Klebsiella pneumoniae isolates from urinary tract infection (UTI) patients in Sylhet city of Bangladesh. At the same time, all isolates were screened for some common virulence genes and four significant isolates were searched for plasmid number and sizes by mini alkaline-lysis method. Among five tested isolates from female UTI patients, gyrase subunit B2 (gyrb2) amplified in all isolates, lipase and nuclease detected in three isolates and serine protease amplifies in two isolates and gave the expected band of 1130 bp, 517 bp, 1055 bp and 211 bp respectively. Two of four isolates showed 9.82 kb plasmid band on agarose gel. Isolates bearing 9.82 kb plasmid were found to be resistant to multiple commercial...

Autores: Cruz,Rita de Cássia Reis; Tanajura,Davi; Almeida,Delvone; Cruz,Marla; Paraná,Raymundo.
Bacterial infections are important factors in decompensation, and they increase the mortality rate of patients with liver cirrhosis. The most common infections among these patients are spontaneous bacterial peritonitis, pneumonia, skin infections and urinary tract infections (UTI). This transversal study evaluated the frequency of UTI in non-hospitalized patients with cirrhosis followed in a hepatology outpatient unit. Patients with clinical, laboratorial, echographic and/or histological diagnosis of cirrhosis were evaluated from April 2002 to August 2004. Patients who accepted participating in this study were submitted to clinical evaluation and the following laboratorial examinations: urine analysis, urine culture, blood culture and hepatic function...

Provedor de dados: 55
Autores: Ramos,Lya Duarte; Lima,Marinus de Moraes; Carvalho,Maurício de; Silva Júnior,Geraldo Bezerra da; Daher,Elizabeth De Francesco.
Pyelonephritis is a pyogenic infection of renal parenchyma that involves the renal pelvis. It is generally of easy diagnosis. The present case report aims to describe two different manifestations of this infection: xanthogranulomatous pyelonephritis and emphysematous pyelonephritis, which have poor prognosis and require a more effective treatment. The two cases were women in the fiftieth and sixtieth decade of life, with diabetes mellitus and history of weight loss. The diagnosis of the renal infection was established through computed tomography and the treatment was based in surgical procedure, with favorable outcome.

A case of urinary tract infection caused by Raoultella planticola after a urodynamic study
Provedor de dados: 55
Autores: Tuğcu,Murat; Ruhi,Caglar; Gokce,Ali M.; Kara,Melih; Aksaray,Sebahat.
Abstract Here we report the case of a patient who developed urinary tract infection after a urodynamic study. The causative agent was Raoultella planticola, a rare opportunistic pathogen that usually invades immunocompromised patients. While a urinary tract infection with R. planticola has been previously described, this is the first report in which an R. planticola infection developed after a urodynamic study. We postulate that the mechanism of infection was direct invasion of the urinary tract from contaminated urodynamic study equipment. Here, we discuss the role played by isotonic solutions in facilitating bacterial reproduction.

Evaluation of urinalysis parameters to predict urinary-tract infection
Provedor de dados: 55
Autores: Santos,Juliana Conrad dos; Weber,Liliana Portal; Perez,Leandro Reus Rodrigues.
We evaluated the performance of automated-flow cytometry, urinalysis dipsticks and microscopic urine sediment analysis as predictors of urinary tract infection. Urine cultures were used as a reference method for comparison. Six-hundred-seventy-five urine samples from hospitalized and not hospitalized patients attended at Hospital Mãe de Deus, Porto Alegre, in south Brazil, were included in the study. Among the individual measures analyzed, intense bacteriuria in the microscopic analysis of urinary sediment gave an accuracy of 92.9%. A combination between intense bacteriuria (microscopic analysis) and &gt;20 leukocytes per µL of urine (flow cytometry) gave a higher accuracy (97.3%). We conclude that though it is laborious, microscopic urinalysis is a good...

Provedor de dados: 55
Autores: Marques,Luiz Paulo José; Flores,Juliana Timóteo; Barros Junior,Onofre de Oliveira; Rodrigues,Giovana Breda; Mourão,Carla de Medeiros; Moreira,Rosa Maria Portella.
BACKGROUND: Urinary tract infections (UTIs) in elderly patients can be a complex problem in terms of approach to diagnosis, treatment, and prevention, because the patients often present nonspecific symptoms. The epidemiological and clinical characteristics of UTI in elderly women were studied, in order to make early diagnosis and prevent serious clinical complications secondary to UTI. METHODS: This was a prospective population-based study, with elderly women, during their first medical office visit. Medical records were obtained by clinical history and physical examination in order to detect signs and symptoms of UTI and the presence of comorbidities. Clean-catch midstream urine specimens for urinary dipstick test, sediment, and culture were collected;...

Autores: Cuba,Gabriel Trova; Pignatari,Antonio Carlos Campos; Patekoski,Katya Silva; Luchesi,Lucimila Jorge; Kiffer,Carlos Roberto Veiga.
Since antimicrobial resistance among uropathogens against current first line agents has affected the management of severe urinary tract infection, we determined the likelihood that antibiotic regimens achieve bactericidal pharmacodynamic exposures using Monte Carlo simulation for five antimicrobials (ciprofloxacin, ceftriaxone, piperacillin/tazobactam, ertapenem, and meropenem) commonly prescribed as initial empirical treatment of inpatients with severe community acquired urinary tract infections. Minimum inhibitory concentration determination by Etest was performed for 205 Brazilian community urinary tract infection Escherichia coli strains from 2008 to 2012 and 74 E. coli bloodstream strains recovered from a surveillance study. Pharmacodynamic exposure...

Provedor de dados: 55
Autores: Guidoni,Eliana Biondi Medeiros; Berezin,Eitan N.; Nigro,Stanley; Santiago,Nataly A; Benini,Vanda; Toporovski,Julio.
Knowledge about antimicrobial resistance patterns of the etiological agents of urinary tract infections (UTIs) is essential for appropriate therapy. Urinary isolates from symptomatic UTI cases attended at Santa Casa University Hospital of São Paulo from August 1986 to December 1989 and August 2004 to December 2005 were identified by conventional methods. Antimicrobial resistance testing was performed by Kirby Bauer's disc diffusion method. Among the 257 children, E. coli was found in 77%. A high prevalence of resistance was observed against ampicillin and TMP/SMX (55% and 51%). The antibiotic resistance rates for E. coli were: nitrofurantoin (6%), nalidixic acid (14%), 1st generation cephalosporin (13%), 3rd generation cephalosporins (5%), aminoglycosides...

Nocardia veterana: disseminated infection with urinary tract infection
Provedor de dados: 55
Autores: Poisnel,Elodie; Roseau,Jean-Baptiste; Landais,Cécile; Rodriguez-Nava,Veronica; Bussy,Emmanuel; Gaillard,Tiphaine.
Nocardia spp. are a group of aerobic actinomycetes widely distributed in soil, and associated with severe opportunistic infections, essentially pulmonary infections. We report the ﬁrst case of disseminated infection associated with urinary tract infection caused by Nocardia veterana . The diagnosis was difﬁcult; despite the presence of pulmonary nodules, the lung biopsies remained negative while only one aerobic blood culture and the urine culture were positive for N. veterana , identiﬁed after a 16S rDNA gene sequence analysis. Few cases of clinical importance due to N. veterana have been published since its characterization. The bacteriological diagnosis of nocardiosis can be difﬁcult to establish because of the delayed growth and the speciﬁc techniques...

Provedor de dados: 58
Autores: Ferreira,Adriano Martison; Martins,Katheryne Benini; Silva,Vanessa Rocha da; Mondelli,Alessandro Lia; Cunha,Maria de Lourdes Ribeiro de Souza da.
Abstract Staphylococcus aureus and Staphylococcus saprophyticus are the most common and most important staphylococcal species associated with urinary tract infections. The objective of the present study was to compare and to evaluate the accuracy of four phenotypic methods for the detection of beta-lactamase production in Staphylococcus spp. Seventy-three strains produced a halo with a diameter ≤28 mm (penicillin resistant) and all of them were positive for the blaZ gene. Among the 28 susceptible strain (halo ≥29 mm), 23 carried the blaZ gene and five did not. The zone edge test was the most sensitive (90.3%), followed by MIC determination (85.5%), but the specificity of the former was low (40.0%). The nitrocefin test was the least sensitive (28.9%)....

Provedor de dados: 58
Autores: Higuchi,Cristian Kendi; Corrêa,Carlos Roberto; Rall,Vera Lucia Mores; Fernandes Junior,Ary.
The use of the Diramic system in microbiological diagnosis of urinary tract infections (UTI) was evaluated. This system was developed at the National Center for Scientific Research of Cuba, and it reads turbidimetric changes of microbial growth in culture media at 37ºC incubated for 4 hours. A total of 396 urine specimens were tested in the Laboratory of Microbiology of the School of Medicine - UNESP, Brazil using the Diramic system and the counting of colony forming units per urine millimeter (calibrated loop) as the reference method. The coincidence rate between the two methods was 96.46% (382 urine samples), and the differences in results were not significant (p&lt;0.05). Sensitivity and specificity rates were 84.37% and 98.80%, respectively. False...
