Background: Group B Streptococcus (GBS) is major cause of serious life threatening
infections including sepsis, pneumonia and meningitis in neonates as well as in pregnant
women. Capsular polysaccharide typing is significant and essential for epidemiological
studies of GBS. Objectives: The aim of the current study was to differentiate genotypes of
GBS clinical isolates based on the polymerase chain reaction (PCR) to acquire information
about distribution of GBS types in Hamedan, Iran. Methods: In this experimental study we …

Background: Group B streptococcus (GBS) is the major cause of serious life threatening
infections in neonates, pregnant women, and other adults with underlying diseases.
Capsular polysaccharide typing is a significant way for epidemiological studies of GBS, the
pathogenesis, and other studies associated with GBS infections including surveillance
programs and vaccine development in future. Molecular serotyping (MS) methods offer more
accurate and reliable typing of bacteria. The aim of current study was to differentiate …
