DOI: 10.1016/j.vetmic.2018.06.007
Abstract: Specific nasopharyngeal bacterial communities can provide colonization resistance against respiratory pathogens in cattle. However, the role of bacterial communities of the lower airways in respiratory health remains largely unknown. Therefore, our objective was to compare… read more here.
