The role of chronic infection in lung disease
The lungs of individuals with cystic fibrosis are colonized and infected by bacteria from an early age. These bacteria, which often spread amongst individuals with CF, thrive in the altered mucus, which collects in the small airways of the lungs. This mucus encourages the development of bacterial microenvironments (biofilms) that are difficult for immune cells (and antibiotics) to penetrate. The lungs respond to repeated damage by thick secretions and chronic infections by gradually remodeling the lower airways (bronchiectasis), making infection even more difficult to eradicate.[1]
Over time, both the types of bacteria and their individual characteristics change in individuals with CF. In the initial stage, common bacteria such as Staphylococcus aureus and Hemophilus influenzae colonize and infect the lungs. Eventually, however, Pseudomonas aeruginosa (and sometimes Burkholderia cepacia) dominates. Once within the lungs, these bacteria adapt to the environment and develop resistance to commonly used antibiotics. Pseudomonas can develop special characteristics that allow the formation of large colonies, known as "mucoid" Pseudomonas and rarely seen in people that do not have CF.[1]
One way in which infection has spread is by passage between different individuals with CF.[2] In the past, people with CF often participated in summer "CF Camps" and other recreational gatherings.[3][4] Hospitals grouped patients with CF into common areas and routine equipment (such as nebulizers)[5] was not sterilized between individual patients.[6] This led to transmission of more dangerous strains of bacteria among groups of patients. As a result, individuals with CF are routinely isolated from one another in the healthcare setting and healthcare providers are encouraged to wear gowns and gloves when examining patients with CF in order to limit the spread of virulent bacterial strains.[7] Often, patients with particularly damaging bacteria will attend clinics on different days and in different buildings than those without these infections.
