BCO diagnoses are listed along with necropsy comments.

Abbreviations: FHN, femoral head necrosis; FHS, femoral head separation; KB, kinky back; LF, left femur; LT, the left tibia; N, normal; RF, right femur; RT, right tibia; T4, vertebral joint; THN, tibial head necrosis; THNS, THN severe; TD, tibial dyschondroplasia.

High Colony Counts lists the Species diagnosis from 16S rRNA gene sequencing where a large number (>50) of same color colonies were recovered from one or more Site(s) indicating high probability of infection.
