Prevalencia de colonización vaginorrectal por Streptococcus agalactiae y su perfil de sensibilidad en mujeres embarazadas atendidas en un hospital de tercer nivel

摘要: Introduction: Streptococcus agalactiae is the main etiological agent causing invasive infection of newborn with symptoms that may be associated septicemia, pneumonia or meningitis and prevalences up to 50% worldwide where there an increase in antibiotic resistance. Objective: To estimate prevalence vagino-rectal colonization by S. its sensitivity profile pregnant women attending a third-level hospital. Materials methods: One hundred twenty one were sampled vaginal rectal swabs. The cultures carried out following methodology recommended CDC, chromID Strepto B agar was added. suggestive colonies identified biochemically profiles according CLSI determined. As control, pneumoniae ATCC 49619 12403 used. Results: Pregnant 20.66%, total 40 isolates which 12.5% non-sensitivity penicillin. Sensitivity levofloxacin, clindamycin erythromycin 100%, 92.5% y 87.5%, respectively, phenotypes iMLSB (3/40) M (2/40). No tetracycline found. Conclusions: study population obtaining not sensitive penicillin resistance macrolides lincosamidas Kirby-Bauer technique, so importance carrying active colonized perform constant epidemiological surveillance detect changes isolates.
