Objective:
To identify the prevalence of colonization of mexican pregnant women with Group B streptococci, based on a mexican literature review.
Methods:
Trials of prevalence for Group B Streptococci colonization in mexican pregnant women were indentified using a MEDLINE, Artemisa, LILACS and Imbiomed search. Studies were elected only if in the result considered prevalence of Group B Streptococci colonization.
Results:
Nine studies describing prevalence of Group B Streptococci colonization in Mexico. The global prevalence of Group B Streptococci colonization in pregnant women was 9.5% with range of 0.46 to 38.7%. The 9.5% rate of maternal colonization with Group B Streptococci found in our revision is significantly bigger than the rates found by many authors (chi2 < 0.05).
Conclusions:
The variability rates of prevalence for Group B Streptococci colonization in Mexico, to implicate different decisions about the perinatal management. The 9.5% rate of maternal colonization in our review is similar to 10.3% rate, national reference since some years ago.
