Because of the difficulties people with Immotile Cilia Syndrome have with expelling mucous from parts of the respiratory tract, mucous, infected with bacteria, tend to persist in the bronchial tubes and sinuses all the time. From time to time, the number of bacteria in the bronchial tubes or sinuses increase, leading to acute bronchitis or pneumonia, or acute sinusitis.


common bacteria found in people with Immotile Cilia Syndrome: Streptococcus pneumonia, Staphylococcus aureus, Hemophilus Influenzae and Hemophilus species, and Pseudomonas aeruginosa
