2 Anaerobic Bacteria Species Tied to Declining Lung Health in Adults

Two types of bacteria — Porphyromonas pasteri and Prevotella nanceiensis — were found to be highly prevalent in the mucus of adults with cystic fibrosis (CF) and associated with a progressive decline in lung health, a study reported. These two bacteria differ from previously identified, disease-exacerbating bacteria in being…

NIH Grants $2.7M for Research on Anaerobic Bacteria’s Role in CF Flare-ups

The National Institutes of Health (NIH) has granted $2.7 million to Michigan State University (MSU) scientist Robert Quinn to investigate, in collaboration with Spectrum Health, the role of anaerobic bacteria in the development of flare-ups among patients with cystic fibrosis (CF). Anaerobic bacteria are a type…

#NACFC2016 – CF Lung Exacerbations Driven by Fermentative Bacteria, Preferring Acidic pH

According to a new study, acute exacerbations of cystic fibrosis (CF) are associated with a surge of bacteria that do not depend on oxygen (called anaerobic or fermentative bacteria), which thrive when mucus becomes more acidic. Antibiotic treatment kills this bacteria, allowing Pseudomonas aeruginosa to thrive, but as the treatment effect wanes,…
