The OxyR regulon in nontypeable Haemophilus influenzae.
Nontypeable Haemophilus influenzae (NTHi) is a gram-negative bacterium and a common commensal organism of the upper respiratory tract in humans. NTHi causes a number of diseases, including otitis media, sinusitis, conjunctivitis, exacerbations of chronic obstructive pulmonary disease, and bronchitis. During the course of colonization and infection, NTHi must withstand oxidative stress generated...
متن کاملVaccine Candidates against Nontypeable Haemophilus influenzae: a Review
Nonencapsulated, nontypeable Hemophilus influenzae (NTHi) remains an important cause of acute otitis and respiratory diseases in children and adults. NTHi bacteria are one of the major causes of respiratory tract infections, including acute otitis media, cystic fibrosis, and community-acquired pneumonia among children, especially in developing countries. The bacteria can also cause chronic dise...
متن کاملModified Lipooligosaccharide Structure Protects Nontypeable Haemophilus influenzae from IgM-Mediated Complement Killing in Experimental Otitis Media
UNLABELLED Nontypeable Haemophilus influenzae (NTHi) is a Gram-negative, human-restricted pathogen. Although this bacterium typically colonizes the nasopharynx in the absence of clinical symptoms, it is also one of the major pathogens causing otitis media (OM) in children. Complement represents an important aspect of the host defense against NTHi. In general, NTHi is efficiently killed by compl...
متن کاملSurvival of nontypeable Haemophilus influenzae in macrophages.
In this study we have investigated the ability of nonencapsulated, nontypeable Haemophilus influenzae, NT477 to survive in the J774 mouse macrophage-like cell line. Viable, intracellular nontypeable H. influenzae could still be recovered from macrophages 72 h after phagocytosis. In contrast, H. influenzae strain Rd, an avirulent, nonencapsulated variant of a serotype d strain, was killed within...
متن کاملInvasive Disease Caused by Nontypeable Haemophilus influenzae.
such as sepsis and meningitis, has declined substantially since the introduction of the H. influenzae serotype b vaccine. However, the H. influenzae type b vaccine fails to protect against nontypeable H. influenzae strains, which have become increasingly frequent causes of invasive disease, especially among children and the elderly. We summarize recent literature supporting the emergence of inv...
