Which bacterium is most commonly associated with acute sinusitis?

• A. Staph aureus
• B. Streptococcus pneumoniae
• C. Moraxella catarrhalis
• D. Haemophilus influenzae

Answer: (B)

Streptococcus pneumoniae is recognized as one of the most common pathogens involved in acute sinusitis. This bacterium is a leading cause of bacterial infections of the respiratory tract, including sinusitis, particularly in adults and children. Its prevalence can be attributed to its virulence factors that enable it to colonize the nasopharynx and lead to the obstruction of sinus drainage, which fosters a suitable environment for infection. In acute sinusitis, the inflammation of the nasal passages can lead to blockage and mucus accumulation, creating an ideal condition for bacterial growth. Streptococcus pneumoniae is notably prevalent among patients experiencing these infections, often presenting with symptoms like nasal congestion, facial pain, and purulent nasal discharge. Other bacteria mentioned, while they may also be associated with sinus infections, typically do not have the same prevalence as Streptococcus pneumoniae in cases of acute sinusitis. Understanding the microbial etiology of sinusitis helps guide effective treatment strategies, as identifying Streptococcus pneumoniae as the common culprit allows healthcare providers to tailor their antibiotic choices accordingly.
