1. Evaluation of Haemophilus influenzaetype b carrier status among children 10 years after the introduction of Hib vaccine in Brazil
The aim of the present study was to assess the prevalence of Haemophilus influenzaetype b (Hib) nasopharyngeal (NP) colonisation among healthy children where Hib vaccination using a 3p+0 dosing schedule has been routinely administered for 10 years with sustained coverage (> 90%). NP swabs were collected from 2,558 children who had received the Hib vaccine, o

2. Tipagem molecular da cápsula de Haemophilus influenzae isolados da nasofaringe de crianças de creches de Goiânia / Molecular typing of the capsule of Haemophilus influenzae isolated from the nasopharynx of children in daycare centers in Goiânia
Haemophilus influenzae (Hi) causes infection in children, and is presented in two ways: with six encapsulated serotypes a-f and non-encapsulated or nontypeable (NTHi). Capsulated strains are responsible for a variety of invasive diseases, with meningitis being the most frequent. Nontypeable strains are responsible for respiratory tract infections and acute o

3. Tipagem molecular de Streptococcus pneumoniae isolados da nasofaringe de crianças no contexto da vacinação pneumocócica / Molecular typing of pneumococcal isolated from the nasopharyngeal from children
Objetivos: (i) Apresentar uma revisão focando as vacinas pneumocócicas e o portador de S. pneumoniae na nasofaringe; (ii) realizar a tipagem capsular de pneumococos colonizadores de nasofaringe de crianças de creches pela técnica de multiplex PCR; (iii) identificar o perfil MLST dos pneumococos isolados na nasofaringe; (iv) identificar os tipos capsulare

4. 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

6. Ineffectiveness for infants of immunization of mothers with pneumococcal capsular polysaccharide vaccine during pregnancy
Pneumococcal (Pnc) carriage is associated with pneumococcal diseases. Breast feeding and maternal vaccination may be a useful approach to prevent pneumococcal infection in young infants. We examined the risk of Pnc carriage by infants at six months of age after pneumococcal polysaccharide vaccination of pregnant women. We selected 139 pregnant woman. The wom

7. 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

8. Prevalência de bastonetes gram-negativos isolados da nasofaringe de crianças de creches do município de Goiânia / Prevalence of gram-negative rods isolated from the nasopharynx of children in daycare centers in Goiânia
Introduction: the nasopharynx (NP) constitutes the primary ecological reservoir or source of dissemination of microorganisms as Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus aureus and Gram-negative bacilli (GNB). Several studies demonstrated that asymptomatic nasopharyngeal (NP) carriage of pathogens is prevalent in young infants and prec

9. 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

10. Naturally acquired immunity to Haemophilus influenzae type B in healthy Cuban children
We have evaluated the prevalence of antibody to immunogenicity of Haemophilus influenzae type b (Hib) in a group of 4 to 5 years old healthy children, who were too old to be included in the first vaccinated cohort when Hib vaccination begun in Cuba in 1999. Serum capsular polysaccharide specific IgG antibody concentrations were measured in 974 healthy childr

11. An epidemiological study of Haemophilus influenzae at a Brazilian day care center
Day care centers are a relatively new phenomenon in Brazil that bring together large numbers of young children susceptible to contagious diseases. Haemophilus influenzae (Hi) is an important infection in the age range of those attending day care centers. In the present study, the carriage rate of Haemophilus influenzae was identified in 38 day care attendees

12. Nasopharyngeal carriage of pneumococci in children with sickle cell disease.
Nasopharyngeal carriage of Streptococcus pneumoniae was studied in children with sickle cell disease. The incidence of nasopharyngeal isolation was 17.8%. Groups 23 and 6 and type 14 predominated.
