13. High prevalence of methicillin resistance and PVL genes amongStaphylococcus aureus isolates from the nares and skin lesions of pediatric patients with atopic dermatitis
Staphylococcus aureus is highly prevalent among patients with atopic dermatitis (AD), and this pathogen may trigger and aggravate AD lesions. The aim of this study was to determine the prevalence of S. aureus in the nares of pediatric subjects and verify the phenotypic and molecular characteristics of the isolates in pediatric patients with AD. Isolates were

14. Genetic diversity and antimicrobial resistance in Streptococcus agalactiae strains recovered from female carriers in the Bucharest area
For the first time, we used multilocus sequence typing (MLST) to understand how Romanian group B streptococcus (GBS) strains fit into the global GBS population structure. Colonising isolates recovered from adult human females were tested for antibiotic resistance, were molecularly serotyped based on the capsular polysaccharide synthesis (cps) gene cluster an

15. Análises in silico da filogenia e do perfil de genes associados à virulência, dos genomas de linhagens de Escherichia coli de origem aviária
As infecções causadas por linhagens de Escherichia coli de origem aviária (APEC) são responsáveis por perdas significativas na indústria avícola em todo mundo. Risco zoonótico tem sido atribuído às linhagens APEC, devido às semelhanças existentes entre elas e linhagens de E. coli patogênicas extraintestinais (ExPEC) de origem humana, causadoras

16. Acinetobacter baumannii produtor de oxacilinases (OXA) no Brasil: impacto clínico, epidemiológico e opções terapêuticas
Seguindo uma tendência mundial, no Brasil, infecções por cepas de Acinetobacter baumannii multirresistentes (MRs) produtoras de carbapenemases do tipo oxacilinases (OXA) classe D de Ambler são atualmente consideradas uma emergência clínica e epidemiológica. Cepas de A. baumannii produtoras de OXA têm sido reportadas nos estados de Alagoas, Amazonas,

17. Novel methicillin-resistant coagulase-negative Staphylococcus clone isolated from patients with haematological diseases at the Blood Bank Centre of Amazon, Brazil
Methicillin-resistant Staphylococcus remains a severe public health problem worldwide. This research was intended to identify the presence of methicillin-resistant coagulase-negative staphylococci clones and their staphylococcal cassette chromosome mec (SCCmec)-type isolate from patients with haematologic diseases presenting bacterial infections who were tre

18. Extended genetic analysis of Brazilian isolates of Bacillus cereus and Bacillus thuringiensis
Multiple locus sequence typing (MLST) was undertaken to extend the genetic characterization of 29 isolates of Bacillus cereus and Bacillus thuringiensis previously characterized in terms of presence/absence of sequences encoding virulence factors and via variable number tandem repeat (VNTR). Additional analysis involved polymerase chain reaction for the pres

19. Community-acquired methicillin-resistant Staphylococcus aureus carrying SCCmec type IV in southern Brazil
INTRODUCTION: Methicillin-resistant Staphylococcus aureus (MRSA) is an important pathogen commonly associated with nosocomial infections. However, it has also been associated with community-acquired skin and soft tissue infections (CA-MRSA). There are few data on the identification and prevalence of CA-MRSA infections in Brazil. METHODS: This is a cross-sect

20. Caracterização molecular e perfil de sensibilidade de Candida tropicalis isoladas em corrente sanguínea e cateter de pacientes internados em hospitais de ensino / Molecular characterization and susceptibility profile of Candida tropicalis isolated from bloodstream culture and catheter in nosocomial patients from teaching hospitals
Infecções causadas por Candida tropicalis (C. tropicalis) são associados à elevada morbi-mortalidade, e foram consideradas como importantes causas de infecção de corrente sanguínea no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HCFMUSP) de março de 1998 a março de 2001. Adicionalmente, são responsáveis pelo aumen

21. Determinação de sorotipos capsulares de Streptococcus pneumoniae por Multiplex-PCR sequencial / Determination of capsular serotypes of Streptococcus pneumoniae by Multiplex-PCR sequence
S. pneumoniae coloniza a nasofaringe e é um dos principais agente de otite média, pneumonia, bacteremia e meningite com altas taxas de morbidade e mortalidade. Estima-se que 1,6 milhões de pessoas morram de doença pneumocócica por ano, a maioria crianças menores de cinco anos de idade, principalmente em países em desenvolvimento. A cápsula polissarí

22. Diversidade genética de Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) e caracterização molecular das linhagens de Wolbachia associadas / Genetic diversity of Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) and molecular characterization of the associate strains of Wolbachia
Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) is an exotic insect in Brazil, first recorded in the 40s. Although it causes direct damage, D. citri only received attention as a pest in 2004, when the \"Huanglonbing\" (HLB) disease was confirmed infecting citrus in Brazil, and subsequently related to D. citri as vector. Currently, there is no cure for

23. A combined approach of VNTR and MLST analysis: improving molecular typing of Argentinean isolates of Leptospira interrogans
Leptospirosis is an emerging infectious disease that has been identified as both a human and animal health problem worldwide. Regular outbreaks associated with specific risk factors have been reported in Argentina. However, there are no available data concerning the genetic population level for this pathogen. Therefore, the aim of this work was to describe t

24. Emergence of clonal complex 5 (CC5) methicillin-resistant Staphylococcus aureus (MRSA) isolates susceptible to trimethoprim-sulfamethoxazole in a Brazilian hospital
In this study, genotyping techniques including staphylococcal chromosomal cassette mec (SCCmec) typing, pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST) and restriction-modification tests were used to compare the molecular characteristics of methicillin-resistant Staphylococcus aureus (MRSA) isolates recovered at two times within a
