title: Multi locus sequence type comparison of invasive and commensal Haemophilus influenzae isolates from Delhi.
abstract: Haemophilus influenzae is a major public health concern in the developing world. The most virulent strain is H. influenzae Type b (Hib). Hib also constitutes a major portion of nasopharyngeal commensal flora in otherwise healthy individuals. Through dendogram based on composite gene sequences of seven multi locus sequence type genes, it was observed that invasive and commensal isolates made two completely separate clusters which are indicative of independent evolution of these two groups of H. influenzae in the Indian subcontinent.
