13. The genetic diversity and phenotypic characterisation of Streptococcus agalactiae isolates from Rio de Janeiro, Brazil
Streptococcus agalactiae isolates are more common among pregnant women, neonates and nonpregnant adults with underlying diseases compared to other demographic groups. In this study, we evaluate the genetic and phenotypic diversity in S. agalactiae strains from Rio de Janeiro (RJ) that were isolated from asymptomatic carriers. We analysed these S. agalactiae

14. Prevalence of pneumococcal serotypes and resistance to antimicrobial agents in patients with meningitis: ten-year analysis
OBJECTIVES: To determine the prevalence of pneumococcal serotypes and antimicrobial susceptibility in patients with meningitis, and to evaluate the implications for vaccine coverage. METHODS: Pneumococcal strains obtained from normally sterile fluids from patients admitted with meningitis were isolated at the Hospital de Clínicas of the Universidade Federal

15. Sensibilidade a antimicrobianos e sorotipos de Streptococcus pneumoniae isolados de portadores e de indivÃduos com infecÃÃo sistÃmica em Fortaleza, Brasil. / Antibiotic Resistance and Serotypes of Streptococcus pneumoniae Isolated from Carriage and individuals with Sistemic Infection in Fortaleza, Brazil.
Streptococcus (S.) pneumoniae is considered the principal causative agent of morbidity and mortality in children younger than five years of age. All pneumococcal diseases are initiated by establishing a S. pneumoniae colonization in nasopharynx, the disease progressing to systemic disease if natural barrier are crossed. During the last decades, the increasin

16. Phenotyping and genotyping methods applied to investigate the relatedness of brazilian isolates of enterobacter cloacae
In order to evaluate the resolving power of several typing methods to identify relatedness among Brazilian strains of Enterobacter cloacae, we selected twenty isolates from different patients on three wards of a University Hospital (Orthopedics, Nephrology, and Hematology). Traditional phenotyping methods applied to isolates included biotyping, antibiotic se

17. Prevalência de sorotipos e resistência a antimicrobianos de cepas invasivas do Streptococcus pneumoniae em pacientes com diagnóstico de meningite admitidos em um hospital universitário
O objetivo deste trabalho foi avaliar o perfil dos sorotipos e a resistência a antimicrobianos de cepas de pneumococo obtidas a partir de espécimes clínicos de indivíduos admitidos com diagnóstico de meningite no Hospital de Clinicas da Universidade Federal de Uberlândia (HC-UFU). Cepas invasivas de pneumococo isoladas no Laboratório de Análises Clí

18. Prevalência, expressão de leucotoxina e sorotipos de Aggregatibacter actinomycetemcomitans e sua associação à doença periodontal / Prevalence, expression of the leukotoxin and serotypesspecific of the Aggregatibacter actinomycetemcomitans according to periodontal profile
Estudos indicam que indivíduos com lesões periodontais severas apresentam maior probabilidade de serem colonizados por aggregatibacter actinomycetemcomitans de máxima leucotoxicidade (max LTX), enquanto, clones de mínima leucotoxicidade (min LTX) se associam a indivíduos com reduzida perda de inserção conjuntiva e óssea alveolar. Além disso, a sever

19. Pulsed-field gel electrophoresis, virulence determinants and antimicrobial susceptibility profiles of type Ia group B streptococci isolated from humans in Brazil
Group B streptococci (GBS) infections occur worldwide. Although serotyping has been used for epidemiologic purposes, this does not accurately characterize enough members of a genetically heterogeneous bacterial population. The aims of this work were to evaluate the genetic diversity of 45 type Ia GBS strains isolated in Brazil by pulsed-field gel electrophor

20. Serology of flagellar antigens from strains of enteropathogenic Escherichia coli (EPEC) and Shiga Toxin producing E. coli (STEC) isolated from different animals and comparative analysis of the fliC gene by PCR-RFLP. / Sorologia de antígenos flagelares de amostras de Escherichia coli Enteropatogênicas (EPEC) e E. coli produtoras da Toxina de Shiga (STEC) isoladas de diferentes animais e análise comparativa do gene fliC por PCR-RFLP.
The Escherichia coli species consists of a group of typically non-pathogenic bacteria present in the intestinal tract of humans and animals. Strains are serotyped according to their O (somatic), H (flagellar) and K (capsular) surface antigens, in order to distinguish these microorganisms from the non-pathogenic members of the intestinal microbiota. The flage

21. Impacto dos novos pontos de corte de sensibilidade nas taxas de resistência antimicrobiana de cepas invasivas de pneumococo recupera das de pacientes com pneumonia
The aim of this search was to evaluate the impact of penicillin and ceftriaxone new susceptibility breakpoints in reporting resistance of pneumococcus invasive strains obtained from patients hospitalized for pneumonia. Pneumococcus strains obtained from normally sterile fluids from pneumonic patients were isolated and identified at Uberlândia Federal Univer

22. Study of the pneumococcal pneumonia of the childrens hospitalized in the pediatrics ward at the University Hospital of the University of São Paulo / Estudo das pneumonias causadas por Streptococcus pneumoniae em crianças internadas na enfermaria de pediatria do Hospital Universitário da Universidade de São Paulo
Introduction: Currently, the annual incidence of the acquired pneumonia in the developing country communities are around 150.7 million cases, among childrens under 5 years of age, and 11 to 20 million (7-13%) of those require hospitalization due to their gravity. In general, the treatments used to be empirical, however, it is important to be noted that Strep

23. FATORES DE RISCO E EPIDEMIOLOGIA MOLECULAR DE Streptococcus pneumoniae NÃO SUSCETÍVEIS À PENICILINA ISOLADOS DE NASOFARINGE DE CRIANÇAS QUE FREQUENTAM CRECHES EM GOIÂNIA-GO, BRASIL / Risk factors and molecular epidemiology of penicillin nonsusceptible Streptococcus pneumoniae isolates in nasopharynx of children attending day-care centers in Goiânia- GO, Brazil
Objectives: (i) to identify risk factors for S. pneumoniae penicillin nonsusceptible isolates (PNSp) in children attending day-care centers (DCCs) in Goiânia, Brazil and to assess the genetic patterns of pneumococcal isolates; (ii) to estimate the coverage for carriage serotypes for the 7-valente (PCV7) pneumococcal conjugate vaccine, and for the investigat

24. Multiplex-PCR serotyping of Listeria monocytogenes isolated from human clinical specimens
The genus Listeria is composed of six species of which Listeria monocytogenes is considered the single pathogenic species that causes listeriosis in humans. Of the 13 serovars of L. monocytogenes, 1/2a, 1/2b and 4b are responsible for the majority of clinical cases. The aim of this work was to detect L. monocytogenes in the cerebrospinal fluid sample of prem
