infections can significantly impact the health and productivity of dairy cattle. Asymptomatic carriage of can make it difficult to identify and monitor this pathogen across a herd. Therefore, a more focused census on dairy farms is needed to better understand the dynamics of asymptomatic carriage.

- Using oral swabs to collect remnants of stomach content during rumination in dairy cows can closely replicate ruminal bacterial communities, making it beneficial for large-scale studies on the rumen microbiome.
- The quality of these swabs can vary, affecting their ability to accurately reflect the microbiome due to factors such as sampling time, cow behavior, and swab color.
- Our research shows that darker swabs correlate with increased bacterial diversity while lighter swabs display greater variation; darker swabs also relate to the ruminal fungal community, indicating their potential as a more accurate representation of the ruminal environment.
Disturbance events can impact ecological community dynamics. Understanding how communities respond to disturbances and how those responses can vary is a challenge in microbial ecology. In this study, we grew a previously enriched specialized microbial community on either cellulose or glucose as a sole carbon source and subjected them to one of five different disturbance regimes of varying frequencies ranging from low to high.
