“…This worldwide variability is related to different sociocultural, geographic, climatic, biological and methodological determinants. Brazilian studies have found rates ranging from 5 to 25% (3,5,22,23,26,29,30). Our finding of a 32.6% rate of GBS prevalence using the genetic detection directly from the enrichment culture is worrisome and the highest reported in the country to our knowledge so far.…”

Group B Streptococcus (GBS) is still not routinely screened during pregnancy in Brazil, being prophylaxis and empirical treatment based on identification of risk groups. This study aimed to investigate GBS prevalence in Brazilian pregnant women by culture or polymerase chain reaction (PCR) associated to the enrichment culture, and to determine the antimicrobial susceptibility patterns of isolated bacteria, so as to support public health policies and empirical prophylaxis. After an epidemiological survey, vaginal and anorectal specimens were collected from 221 consenting laboring women. Each sample was submitted to enrichment culture and sheep blood agar was used to isolate suggestive GBS. Alternatively, specific PCR was performed from enrichment cultures. Antimicrobial susceptibility patterns were determined for isolated bacteria by agar diffusion method. No risk groups were identified. Considering the culture-based methodology, GBS was detected in 9.5% of the donors. Twenty five bacterial strains were isolated and identified. Through the culture-PCR methodology, GBS was detected in 32.6% specimens. Bacterial resistance was not detected against ampicillin, cephazolin, vancomycin and ciprofloxacin, whereas 22.7% were resistant to erythromycin and 50% were resistant to clindamycin. GBS detection may be improved by the association of PCR and enrichment culture. Considering that colony selection in agar plates may be laboring and technician-dependent, it may not reflect the real prevalence of streptococci. As in Brazil prevention strategies to reduce the GBS associated diseases have not been adopted, prospective studies are needed to anchor public health policies especially considering the regional GBS antimicrobial susceptibility patterns.

“…That is the question Eliana Amaral* Os estudos sobre a prevalência da colonização pelo estreptococo do grupo B (EGB) refletem a preocupação dos grupos de pesquisa nacionais com as complicações associadas a este agente, quando há intervenções eficazes para seu controle. Em artigos publicados na RBGO, sendo um neste fascí-culo, foram avaliadas as prevalências da colonização pelo EGB entre gestantes com mais de 35 semanas realizando pré-natal em hospitais-escola do Paraná e de Santa Catarina 1,2 . Os dois estudos coletaram amostras anal e vaginal e utilizaram meio específico para isolamento e identificação da bactéria, conforme recomendação internacional (Schrag et al, 2002) 3 .…”

“…Nos eventos científicos e publicações de obstetras, neonatologistas e infectologistas observa-se o interesse crescente pelo tema. A preocupação de quantificar inicialmente o problema, como o fizeram Beraldo et al 1 e Pogere et al 2 , é louvável e necessária para embasar discussões no país. 7 .…”

“…Beraldo et al 1 e Pogere et al 2 não encontraram nenhuma associação entre idade, paridade e escolaridade com colonização materna. Pogere et al 2 observaram maior prevalência entre mulheres com mais de um parceiro sexual no último ano e maior freqüência de relações sexuais (55,6% ), uma associação que não tem sido consistentemente relatada na literatura.…”
