(2018). Colonization of the skin and the nasophaynx can occur shortly after birth. Normal flora, if disrupted, can multiply and turn into pathogens that cause infection. 8. When disrupted, this membrane releases toxic substances called endotoxins. Researchers are developing new treatments for rare lung diseases. If P. aeruginosa is the predominant organism growing in a tracheal aspirate culture from a ventilated patient with symptoms of pneumonia, it is likely the causative pathogen. Rare lung diseases impact your breathing and tend to worsen over time. Treatment is based on the results of the culture. A procedure called bronchoscopy is used to get a sample (biopsy or brush) of lung tissue or fluid.

URT is inhabited by a diverse group of commensal bacteria and fungi species. Some rare lung diseases, such as PAH, are no longer considered orphan diseases after researchers and providers give them more attention. It is a Gram-negative, aerobic rod belonging to the bacterial family Pseudomonadaceae. Staphylococcus, Streptococcus, and Haemophilus species may also be part of the normal oropharyngeal flora, but they are also more likely to be pathogenic.
