Nontypeable H. influenzae, lacking a capsule, cause URTI like otitis media, sinusitis, bronchitis, and conjunctivitis and are not vaccine-preventable. Typeable strains, such as Hib, cause invasive diseases like epiglottitis, pneumonia, and meningitis in the unvaccinated.
Nontypeable H. influenzae, which lack a capsule and thus cannot be vaccinated against, are associated with upper respiratory tract infections like acute and chronic otitis media, rhinosinusitis, bronchitis, and conjunctivitis. In contrast, typeable strains like H. influenzae type b (Hib) can cause invasive diseases such as epiglottitis, pneumonia, and meningitis in unvaccinated individuals.
| Front | Name (3) diseases which are caused by nontypeable H.influenzae |
|---|---|
| Back | Rhinosinusitis Bronchitis Conjunctivitis H.influenzae (nontypeable strains meaning they lack a capsule) are associated with URTI such as acute and chronic otitis and sinusitis. Nontypeable species lack a capsule so no vaccine can be made Typeable strains such as H. influenzae type b (Hib) cause invasive disease such as epiglottitis | pneumonia | meningitis in unimmunized individuals |
