Nasal culture is performed to identify bacteria (except anaerobes) and Candida spp. fungi in patients with symptoms of rhinitis or rhinosinusitis. This helps to establish the exact cause of the disease and choose the most effective treatment.

Common pathogens of acute bacterial rhinosinusitis: Streptococcus pneumoniae (38%), Haemophilus influenzae (36%), Moraxella catarrhalis (16%), Beta-hemolytic streptococci group A, Staphylococcus aureus

Age-related anatomical and physiological characteristics of children contribute to the fact that rhinosinusitis occurs in children twice as often as in adults.
