Survival of < em > Campylobacter jejuni < /em > during < em > in vitro < /em > culture with mixed bovine ruminal microorganisms in the presence of methanogen inhibitors
The objectives of this experiment were to determine C. jejuni survivability in mixed in vitro rumen microbial populations and the impact on methane production with or without methane inhibitors 2-bromosulfonate (BES) and/or sodium nitrate. When inoculated into rumen microbial populations without or with 0.5 mM BES, 5.0 mM nitrate or their combination, C. jejuni viability decreased from 4.7 ± 0.1 log10 colony forming units (CFU)/mL after 24 h. Loss of C. jejuni viability was greater (P < 0.05) when incubated under 100% CO2 compared to 50% H2:50% CO2, decreasing 1.46 versus 1.15 log units, respectively. C. jejuni viabili...

Association between indoor bacterial communities, lung function and airway inflammation
Conclusion: We conclude that a higher microbial diversity is associated to higher lung function in males and increased inflammation and lower lung function in females. Further studies are needed understand the relation between exposure to specific types of bacteria and lung conditions. (Source: European Respiratory Journal)

The airway microbiome in Bronchiectasis-COPD overlap: data from the EMBARC-BRIDGE study
Conclusion: We demonstrate in two large cohorts that BE-COPD is associated with reduced microbial diversity and depletion of anti-inflammatory commensal taxa. (Source: European Respiratory Journal)
