Final answer:
The bacteria strain that can cause croup rarely is Haemophilus influenzae Type b, which can also lead to meningitis in young children without adequate vaccination.
Explanation:
The bacteria strain that can cause croup (rarely) is Haemophilus influenzae Type b. Although Haemophilus influenzae Type b is now uncommon in most countries due to the effective Hib vaccine, it can be the primary cause of meningitis in children aged between 2 months and 5 years without vaccination.
The bacteria strain that can cause croup rarely is Haemophilus influenzae Type b, which can also lead to meningitis in young children without adequate vaccination. This encapsulated pleomorphic gram-negative coccobacilli can also be found in the throats of healthy individuals, but infants older than 2 months are susceptible to serious disease if not sufficiently immunized.
Furthermore, Haemophilus influenzae infections can lead to high intracranial pressure, resulting in a considerable mortality rate and the possibility of deafness or brain damage in survivors.
