Distribution of group B streptococcal serotypes in Malaysia

A total of 350 strains of group B streptococci (308 from adults and 42 from neonates) were serotyped. The majority of the isolates from adult patients were from the genito-urinary tract and most of the neonatal isolates were from babies less than 10 days old. Serotype III was the predominant type among all groups of patients and accounted for 50.9% of all serotypes. The second and third most frequently occurring serotypes were II and Ic respectively. Together with type III they made up 87% of the isolates.
