Abstract The advent of next-generation sequencing technologies has uncovered the importance commensal microbial populations in lower respiratory tract (LRT) for mucosal health and their role development bovine disease (BRD). In this study, we aimed to characterize compare LRT microbiota healthy BRD-affected calves Egypt. After assessing clinical scores both groups, post-mortem lung samples from cranial lobes six clinically affected by BRD were collected following slaughter. most prevalent...
