Serotyping Group B Streptococci in a Small Community Hospital: An Analysis of Distribution and Site of IsolationBiochemistry and Microbiology
AbstractObjective: To determine the prevalence and site of isolation of different serotypes of group B streptococcus (GBS) colonization or infection at a small community hospital. Methods: GBS isolates were obtained from a small community hospital and were then serotyped as la, Ib, II, III, IV, V or non-typeable. Hospital records were reviewed for patient sex, age and pregnancy status as well as the site of GBS isolation. Results: GBS serotypes Ia, III and V were most common and accounted for over 60% of the total number of isolates. Serotype Ia was most prevalent in reproductive-age females, while serotypes V and III were most prevalent in non-reproductive-age females and males, respectively. Serotype la was most frequent in both pregnant and non-pregnant females. Serotype IV was more common in this study population than in those from other locations. Conclusions: The GBS serotype distribution in this small community did not differ significantly from distribution described in larger North American centers. A GBS vaccine designed against multiple serotypes would be protective for most of this population.
