Quizplus · Accepted Answer

Haemophilus influenzae is a Gram-negative bacterium that commonly causes acute upper respiratory infections such as otitis media, sinusitis, and bronchitis. In infants aged 3-18 months, it can also cause meningitis, which is a serious infection of the brain and spinal cord. Infants of this age group are more susceptible to invasive infections due to their immature immune systems. Vaccines are available to prevent infections with H. influenzae.
