Cloning of conserved regions of nontypeable Haemophilus influenzae hmw1 core binding domain
Colonization of nontypeable Haemophilus influenzae (NTHi) in nasopharynx causes respiratory tract disease. In 80% of clinical isolates, HMW proteins are the major adhesions and induce protective antibodies in the hosts. Therefore, it can be used as a vaccine candidate. The aim of this study is designing and cloning of the conserved regions of NTHi hmw1 core binding domain.In this study, the sta...
متن کاملNaturally Acquired HMW1- and HMW2-Specific Serum Antibodies in Adults and Children Mediate Opsonophagocytic Killing of Nontypeable Haemophilus influenzae.
The HMW1 and HMW2 proteins are highly immunogenic adhesins expressed by approximately 75% of nontypeable Haemophilus influenzae (NTHi) strains, and HMW1- and HMW2-specific antibodies can mediate opsonophagocytic killing of NTHi. In this study, we assessed the ability of HMW1- and HMW2-specific antibodies in sera from healthy adults and convalescent-phase sera from children with NTHi otitis medi...

متن کاملSerial isolates of persistent Haemophilus influenzae in patients with chronic obstructive pulmonary disease express diminishing quantities of the HMW1 and HMW2 adhesins.
In patients with chronic obstructive pulmonary disease (COPD), the lower respiratory tract is commonly colonized by bacterial pathogens, including nontypeable Haemophilus influenzae. The H. influenzae HMW1 and HMW2 adhesins are homologous proteins that promote bacterial adherence to respiratory epithelium and are the predominant targets of the host immune response. These adhesins undergo graded...
متن کاملEvolutionary and functional relationships among the nontypeable Haemophilus influenzae HMW family of adhesins.
Nontypeable Haemophilus influenzae (NTHi) is a common cause of localized respiratory tract disease and initiates infection by colonizing the nasopharynx. Approximately 75 to 80% of NTHi clinical isolates produce proteins that belong to the HMW family of adhesins, which are believed to facilitate colonization. The prototype HMW adhesins are designated HMW1 and HMW2 and were identified in NTHi st...
