A syphilis co-infection study in human papilloma virus patients attended in the sexually transmitted infection ambulatory clinic, Santa Casa de Misericórdia Hospital, Rio de Janeiro, Brazil 55
Souza,Lúcia Maria de Sena; Miller,William Meihack; Nery,José Augusto da Costa; Andrade,Arnaldo Feitosa Braga de; Asensi,Marise Dutra.
Despite the prevalence of syphilis worldwide, little is known about its manifestations when associated with other Sexually Transmitted Infections (STI), specifically the Human Papilloma Virus (HPV). Current epidemiological studies show that there is a high incidence of both diseases in ambulatory clinics all over Brazil. This study aims to estimate the incidence of syphilis - HPV co-infections, among patients from the STI ambulatory clinic at the Santa Casa da Misericórdia Hospital, Rio de Janeiro, Brazil. Two-hundred and seven patients were seen in the clinic between March and December 2005, of which 113 (54.6%) sought care for an HPV infection. Blood samples were taken from all patients to check syphilis serology using the flocculation and the...

Diversity of genotypes in CTX-M-producing Klebsiella pneumoniae isolated in different hospitals in Brazil 55
Chagas,Thiago Pavoni Gomes; Alves,Ronaldo Mendes; Vallim,Deyse Christina; Seki,Liliane Miyuki; Campos,Leila Carvalho; Asensi,Marise Dutra.
OBJECTIVE: The present study was undertaken to characterize CTX-M ESBL-producing Klebsiella pneumoniae collected from hospitals in different cities of Brazil. MATERIAL AND METHODS: Eighty-five K. pneumoniae strains isolated from hospitalized patients in six different hospitals of three cities of Brazil were analyzed. ESBL production was confirmed by the standard double-disk synergy test and the Etest®. The MIC50 and MIC90 for ESBL-producing isolates were determined by the Etest® method. The antimicrobial susceptibilities of bacterial isolates were determined using the agar diffusion method according to the CLSI. Screening for blaTEM, blaSHV, blaCTX-M genes and class 1 integron was performed by PCR amplification. To determine the genomic diversity of...

Gomes,Marisa Zenaide Ribeiro; Oliveira,Raquel Vasconcellos C. de; Machado,Carolina Romero; Conceição,Magda de Souza da; Souza,Cristina Vieira de; Lourenço,Maria Cristina da Silva; Asensi,Marise Dutra.
INTRODUCTION: Infections caused by multiresistant Pseudomonas aeruginosa (MR-PA) have been associated with persistent infections and high mortality in acquired immunodeficiency syndrome (AIDS) patients. Therefore, understanding the predisposing factors for infection/colonization by this agent is critical for controlling outbreaks caused by MR-PA in settings with AIDS patients. OBJECTIVEAND METHODS: To analyze the presence of factors associated with the acquisition of an epidemic MR-PA strain in a hospital with AIDS-predominant admission. A case-control study was carried out in which cases and controls were gathered from a prospective cohort of all hospitalized patients in an infectious disease hospital during a five-year study period. RESULTS: Multivariate...

Rodrigues,Ana Claudia Souza; Chang,Marilene Rodrigues; Nóbrega,Gabriela Dorn; Rodrigues,Mayara Souza; Carvalho,Nadia Cristina Pereira; Gomes,Beatriz Garcia; Almeida,Dênio Lopes de; Carvalho,Karyne Rangel; Asensi,Marise Dutra.
Infection by Pseudomonas aeruginosa has spread worldwide, with limited options for treatment. The purpose of this study was to investigate metallo-β-lactamase-producing P. aeruginosa strains and compare their genetic profile using samples collected from patients in intensive care units. Forty P. aeruginosa strains were isolated from two public hospitals in Campo Grande, Mato Grosso do Sul State, from January 1st, 2007 to June 31st, 2008. Profiles of antimicrobial susceptibility were determined using the agar diffusion method. Metallo-β-lactamase was investigated using the double-disk diffusion test and PCR. Molecular typing was performed by pulsed-field gel electrophoresis (PFGE). Respiratory and urinary tracts were the most common isolation sites. Of the...

OBJECTIVE: The present studywas designed to evaluate the molecular epidemiology of CTX-M producing Klebsiella pneumoniae, Enterobacter cloacae and Escherichia coli isolated from bloodstream infections at tertiary care hospitals in the State of Rio de Janeiro, Brazil. MATERIAL AND METHODS: A total of 231 nonduplicate Enterobacteriaceae were isolated from five Brazilian hospitals between September 2007 and September 2008. The antimicrobial susceptibility testing was performed by disk diffusion method according to the Clinical Laboratory Standard Institute. Isolates showing resistance to third-generation cephalosporins were screened for ESBL activity by the double-disk synergy test.

Next-generation sequencing virulome analysis of a Yersinia enterocolitica subsp. palearctica bioserotype 4/O:3 ST18 isolated from human blood in Brazil 55
Rusak,Leonardo Alves; Junqueira,Ricardo Magrani; Hofer,Ernesto; Vallim,Deyse Christina; Asensi,Marise Dutra.
Abstract Yersinia enterocolitica is a widespread Gram-negative bacterium that causes gastrointestinal disease and other clinical manifestations in humans. Potentially pathogenic Y. enterocolitica has been isolated in Brazil, from human, environmental, food, and animal sources. Herein we report a genome sequence of Y. enterocolitica subsp. palearctica strain YE 19, serotype O:3, biotype 4, sequence type 18, with virulence determinants isolated from human blood in Rio de Janeiro in 2005. The results corroborate other findings that this strain harbors a set of virulence determinants that could play a role in host pathoadaptation and may also justify the successful dissemination of bioserotype 4/O:3 in Brazil. The presence of strains harboring all of these...

Gomes,Marisa Zenaide Ribeiro; Machado,Carolina Romero; Conceição,Magda de Souza da; Ortega,Jois Alves; Neves,Sonia Maria Ferraz M; Lourenço,Maria Cristina da Silva; Asensi,Marise Dutra.
INTRODUCTION: Authors have reported increased incidence of multiresistant Pseudomonas aeruginosa (MR-PA) infections worldwide over the last decade. Researchers have proposed multifaceted approaches to control MR-PA infections, but none have been reported in the acquired immunodeficiency syndrome (AIDS) setting. OBJECTIVE AND METHODS: Herein we report the impact of a multifaceted intervention for controlling MR-PA over five years in a hospital with AIDS-predominant admissions and describe the clinical characteristics of MR-PA infection in our patient population. The clinical outcomes of infected patients and molecular characteristics of the isolated strains were used as tools for controlling MR-PA infection rates. RESULTS: Significant temporary decrease of...
