Heatmap of OTUs found in lamb lung fluids, oropharyngeal swabs, extraction kit reagent and PBS controls. OTUs were included when they were > 5% abundant in at least one sample. Oropharyngeal swabs partitioned into rumen-like bacterial communities are indicated by green whereas those which were upper aerodigestive tract-like are indicated by a red line. The lung fluid samples from the oropharyngeal-like animals are indicated by blue whereas those from the rumen-type animals are indicated by pink
