Haemophilus Influenzae

Haemophilus influenzae can cause serious invasive disease especially in young children. invasive disease is usually caused by encapsulated strains of the organism. H. influenzae commonly causes ear, eye or sinus infections and pneumonia. The bacterium H. influenzae live in the upper respiratory tract and are usually transmitted by close contact with an infected person. expulsion of air from a sneeze can be inhaled and can also cause infection. In general, there are six types of H. influenzae. Naturally acquired disease caused by H. influenzae seems to occur in humans only. In infants and toddlers, H. influenzae type b (Hib) causes bacteremia, pneumonia and acute bacterial meningitis. Sometimes causes of cellulite, osteomyelitis, epiglottitis, and common infections. Hib disease has no sexual predilection, but women are at risk of puerperal sepsis, chronic salpingitis and tubo-ovarian abscess caused by NTHi colonize the gastrointestinal tract. Hib disease has decreased to 1. 3 / 100, 000 in children. However, Hib remains a major cause of lower respiratory infections in infants and young children in developing countries, where vaccination is not widely used. H. unencapsulated influenzae (non-B type) causes ear (otitis media) and pink eyes () and sinus infections in children and is associated with pneumonia. Treatment of H. influenzae is highly dependent on what area of the body is infected. Antibiotics and supportive care is also useful for this disease. Parenteral antibiotics (eg, ceftriaxone, ceftazidime, cefotaxime, ampicillin-sulbactam, fluoroquinolones, and azithromycin) for patients with uncomplicated meningitis for 7-14 days. Dexamethasone is an important adjunct treatment in patients with meningitis who are older than two months. The use of Hib conjugate vaccines has reduced the number of cases. Hib vaccines are made from capsular polysaccharides were extracted from cultures of Hib bacteria. Several types of Hib conjugate vaccines available for use. All vaccines approved for use in children 15 months old and some were approved for use in children 2 months of age. All vaccines are considered effective. The vaccines are administered by injection.
