Article Synopsis
- Group B Streptococcus (GBS) is a significant cause of contagious bovine mastitis (CBM) in Brazil, with two main lineages (host-generalist and host-specialist) prevailing, which exhibit differences in antimicrobial resistance and zoonotic potential.* ! -
- A study on 156 GBS isolates from Brazil revealed a shift in dominance from clonal complex (CC) 61/67 in the 20th century to CC91 and CC103 in the 21st century, indicating evolving resistance patterns and potential issues with biosecurity within herds.* ! -
- The majority of GBS strains were linked to serotype Ia or III and showed varied resistance to antibiotics, with opportunities for improving
is an important agent of urinary tract infection (UTI) in young women, but information about this pathogen in human microbiota and in common environment is lacking. The aim of this study was to characterize isolates from genitoanal microbiota of 621 pregnant women, 10 minas cheese packs, and five beaches in Rio de Janeiro city and compare PFGE profiles of these isolates with five UTI PFGE clusters described in this city. We investigated 65 isolates from microbiota, 13 from minas cheese, and 30 from beaches and 32 UTI isolates.

Among the 59 isolates, 9 (15%) isolates were mannitol-negative; all of these isolates were categorized as staphylococcal cassette chromosome mec (SCCmec) type IVa. This report emphasizes that mannitol fermentation on mannitol salt agar should not be used as the sole criterion when screening nasal swab specimens for S.

Mem Inst Oswaldo Cruz
February 2013
The epidemiology of urinary tract infections (UTI) by Staphylococcus saprophyticus has not been fully characterised and strain typing methods have not been validated for this agent. To evaluate whether epidemiological relationships exist between clusters of pulsed field gel-electrophoresis (PFGE) genotypes of S. saprophyticus from community-acquired UTI, a cross-sectional surveillance study was conducted in the city of Rio de Janeiro, Brazil.

It is believed that most cases of listeriosis are acquired in the community. A cluster of listeriosis in hospitalized patients prompted the present investigation.
