Haemophilus influenzae (H. influenzae) is a type of bacteria that can cause several different kinds of infections. These bacterial infections can range from mild, such as ear infections, to severe, such as bloodstream infections. The infections typically affect children younger than 5 years old.

Haemophilus is a genus of Gram-negative, pleomorphic, coccobacilli bacteria belonging to the family Pasteurellaceae. [2][3] While Haemophilus bacteria are typically small coccobacilli, they are categorized as pleomorphic bacteria because of the wide range of …

Bacteria called Haemophilus influenzae can cause many types of infections. Some of these infections are mild, while others are serious. In spite of its name, H. influenzae doesn't cause the flu. Vaccines can prevent infections from one type of H. influenzae, type b or Hib.

Haemophilus influenzae (formerly called Pfeiffer's bacillus or Bacillus influenzae) is a Gram-negative, non-motile, coccobacillary, facultatively anaerobic, capnophilic pathogenic bacterium of the family Pasteurellaceae. The bacteria are mesophilic and grow best at temperatures between 35 and 37 °C. [1]

Haemophilus influenzae is a bacterium that causes often-severe infections, particularly among infants. It was first described by Richard Pfeiffer in 1892. During an outbreak of influenza, he found H. influenzae in patients' sputum and proposed a causal association between this bacterium and the clinical syndrome known as influenza.

Haemophilus influenzae are gram-negative bacteria that can cause infection in the respiratory tract, which can spread to other organs. Infection is spread through sneezing, coughing, or touching.

The gram-negative coccobacillus bacteria Haemophilus species cause numerous mild and serious infections, including bacteremia, meningitis, pneumonia, sinusitis, otitis media, cellulitis, and epiglottitis. Diagnosis is by culture, nucleic acid amplification tests, and serotyping.
