Beta-lactamase-negative ampicillin-resistant Haemophilus influenzae type b meningitis in partially immunized immunocompetent child: a case report

Haemophilus influenzae is a Gram-negative coccobacillus that can cause many different kinds of infection, ranging from mild ear infection to life-threatening diseases like epiglottitis and meningitis. Encapsulated type b Haemophilus influenzae was most commonly responsible for Haemophilus influenzae meningitis in children before introduction of Haemophilus influenzae conjugate vaccine. None or partially immunized children are acquiring meningitis owing to resistant strains of Haemophilus influenzae, namely beta-lactamase-negative ampicillin-resistant strain.

We reported the case of a 2-year-old Emirati boy who presented to our emergency department with fever, diarrhea, vomiting, and fluctuating levels of consciousness.
