Molecular epidemiology of group B streptococci in Ireland: associations between serotype, invasive status and presence of genes encoding putative virulence factors

Group B streptococcal isolates (n=159) from the three Dublin maternity hospitals, were serotyped and analysed for the bac, bca, hylB, pepB, and rib genes. The serotype distribution of the isolates was Ia, 19·5%; Ib, 18·9%; II, 10·7%; III, 29·5%; IV, 1·9%; V, 15·1%; non-typeable, 4·4%. There was a st...

The serotype distribution of the isolates was Ia, 19·5%; Ib, 18·9%; II, 10·7%; III, 29·5%; IV, 1·9%; V, 15·1%; non-typeable, 4·4%. There was a statistically significant association between the serotype and invasive status (carriage or infection) of isolates (P
