Molecular Epidemiology of Strains with Reduced Susceptibility and Genetic Profiles of Resistance in the Postvaccination Period.

serotype b has been the main cause of invasive infections in children, during the prevaccination period. More than 20 years after the introduction of the conjugate vaccine against Hib, HiNT has emerged as the cause of localized infections in children and adults. The main objective of this work is to evaluate the susceptibility and resistance mechanisms of strains from carriers and describe the molecular epidemiology and their clonal relationships by multilocus sequence typing (MLST).
