Capsular genotype distribution of Group B Streptococcus colonization among at-risk pregnant women in Sao Paulo, Brazil.

Background: Vaccines in development against Group B Streptococcus (GBS) should contain the most prevalent capsular genotypes screened in the target population. In low- and middle-income countries epidemiological data on GBS carriage among pregnant women, a prerequisite condition for GBS neonatal sepsis, is needed to inform vaccine strategies.

Objective: To investigate the prevalence of different GBS capsular genotypes that colonizes at-risk pregnant women in a private maternity hospital in São Paulo, Brazil.

Antifungal susceptibility of 1000 Candida bloodstream isolates to 5 antifungal drugs: results of a multicenter study conducted in São Paulo, Brazil, 1995-2003.

We evaluated all Candida sp. bloodstream isolates obtained from patients admitted to 4 tertiary care hospitals between 1995 and 2003 in the city of São Paulo, Brazil. Susceptibility to amphotericin B, 5-fluorocytosine, fluconazole (FCZ), itraconazole (ITZ), and voriconazole (VCZ) was determined using the Clinical Laboratory Standards Institute broth microdilution method.

A pseudo-outbreak of vancomycin-resistant Enterococcus faecium.

Five VRE isolates were reported from sterile samples. No infections were diagnosed among the patients, who were on different wards. PFGE showed that all five isolates were clonal.

A survey of the incidence of neonatal sepsis by group B Streptococcus during a decade in a Brazilian maternity hospital.

Group B Streptococcus (GBS) is the main etiological agent of neonatal sepsis in developed countries, however there is no detailed information on its incidence in Brazil. We registered the incidence and lethality of GBS infection in a Brazilian private maternity hospital from April 1991 to March 2000. Maternal risk factors contributing to neonatal infections were also scored.
