Absence of an important vaccine and diagnostic target in carriage- and disease-related nontypeable Haemophilus influenzae

Clin Vaccine Immunol. 2014 Feb;21(2):250-2. doi: 10.1128/CVI.00632-13. Epub 2013 Nov 27.

Abstract

Nontypeable Haemophilus influenzae (NTHi)-associated disease is a major health problem globally. Whole-genome sequence analysis identified the absence of hpd genes encoding Haemophilus protein D in 3 of 16 phylogenetically distinct NTHi isolates. This novel finding is of potential clinical significance, as protein D and hpd represent important NTHi vaccine antigen and diagnostic targets, respectively.
