1. Incidence and risk factors for major infections in hospitalized children with nephrotic syndrome
RESUMO Introdução: Crianças com síndrome nefrótica apresentam maior risco de infecções devido ao próprio status da doença e ao uso de vários agentes imunossupressores. Em grande parte, as infecções desencadeiam recidivas que exigem hospitalização, com risco aumentado de morbidade e mortalidade. Este estudo teve como objetivo determinar a incid

2. Vaccination coverage in a cohort of HIV-infected patients receiving care at an AIDS outpatient clinic in Espírito Santo, Brazil
Abstract This cross-sectional study assessed the immunization status of human immune deficiency virus (HIV)-infected patients receiving care at an outpatient clinic in Brazil. The sociodemographic characteristics, CD4 count and HIV viral load of 281 out of 612 adult outpatients were analyzed. A total of 331 patients were excluded because of no availability o

3. Clinical and microbiological implications of invasive pneumococcal disease in hospitalized patients (1998–2013)
Abstract Introduction Infections caused by Streptococcus pneumoniae (pneumococcus) still represent a challenge for health systems around the world. Objective The objective of this study was to assess microbiological and clinical aspects in hospitalized patients with invasive pneumococcus disease between 1998 and 2013. Materials and methods This was a retr

4. 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

6. 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

7. Nasopharyngeal colonization and penicillin resistance among pneumococcal strains: a Worldwide 2004 update
Surveillance of nasopharyngeal pneumococcus has proven to be a valuable tool for the monitoring of antibiotic resistance. We reviewed the latest information on colonization rate and penicillin resistance by making a MEDLINE search, using the terms "nasopharyngeal carriage" and "Streptococcus pneumoniae". Out of 225 articles found, data from 109 recent public

8. Cloning, expression and purification of proteins of surface, PsaA and fragments of PspA from Streptococcus pneumoniae / Clonagem, expressão e purificação das proteínas de superfície, PsaA e fragmentos de PspA de Streptococcus pneumoniae
Streptococcus pneumoniae is the main causative agent of bacterial pneumonia. The current vaccines available contain capsular polysaccharide conjugated or not with carrier proteins. However these are either too expensive or do not protect the high-risk groups. Surface proteins of S. pneumoniae, such as PsaA and PspA, are considered strong vaccine candidates.

10. Etiology of childhood community acquired pneumonia and its implications for vaccination
Pneumonia is an important cause of morbidity and mortality among children throughout the world. Vaccines are available for some organisms, but they are underutilized and/or still in development. To evaluate the potential impact of vaccines, we review studies in which the etiology of childhood community-acquired pneumonia was recorded. In North America and Eu

11. Community acquired pneumonia among pediatric outpatients in Salvador, Northeast Brazil, with emphasis on the role of pneumococcus
Pneumonia is one of the leading causes of hospitalization and death among children in developing countries, and mortality due to pneumonia has been associated with S. pneumoniae infection. This investigation was designed to describe the antimicrobial susceptibility and serotype patterns of pneumococcal strains recovered from the blood of children with commun

12. Host defense against the pneumococcus in T-lymphocyte-deficient, nude mice.
Resistance to pneumococcal infection was tested in T-lymphocyte-deficient, nude (nu/nu) mice. Pneumococcal serum opsonizing activity, in vivo phagocytosis of the pneumococcus, and the mean lethal dose for the pneumococcus were all found to be the same in nude mice as in control (+/+) mice. T-lymphocytes do not appear to play a significant role in the host's
