sciencedaily : reported that New study shows how bacteria get into the lungs: Findings could help disease research -- ScienceDaily

Unlike the gut, healthy lungs are an inhospitable environment for bacteria, with little nutrition, and constant surveillance by the lung's immune system. "This is the most comprehensive topographic survey of the healthy lung microbiome to date. Suspicion of such contamination has kept some researchers from fully accepting the results of previous lung microbiome research. "I certainly look at my kids with their constantly runny noses and wonder if their lung microbiome look more 'nasal' than 'oral.'" The team got samples of lung bacteria using two different techniques to sample nine separate sites in the lungs of each volunteer.

Gut bacteria could be affecting the body's response to a new type of cancer treatment

Cancer immunotherapy - treatments that harness the body's immune system to fight cancer - has been gaining traction in recent years as a new approach to treating the disease. First, they had more diverse gut bacteria and a larger concentration of a specific type of bacteria called Clostridiales bacteria, specifically in the Ruminococcaceae family. Other factors could influence how people respond too, so even if targeting the microbiome did help some, others still might not benefit from the cancer immunotherapy. Even so, Wargo considers the results a "paradigm shifter", when it comes to considering new approaches to get people to respond to these cancer immunotherapy drugs. Of that group, 43 patients had contributed faecal samples and were on anti-PD-1 therapy - a type of cancer immunotherapy that involves what are called checkpoint inhibitors.
