Abstract: | The frequency of capsulated or non-capsulated Haemophilus influenzae strains colonisation among children attending day-care centres or orphanages has been studied. Detection of capsulated or non-capsulated H. influenzae strains has been compared for agglutination test and PCR. Misdiagnosing of H. influenzae serotype with agglutination found in the study suggest that the frequency of Hib strains colonizing the nasopharynx might be lower that previously evaluated. Due to perspectives of the wider use of Hib Immunisation in the future, more efficient diagnosis scheme for identification/differentiation of capsulated and non-capsulated H. influenzae strain should be undertaken. |
