Bacterial topography and factors shaping the porcine respiratory microbiome. The porcine respiratory microbiome is divided into the URT (upper pie chart) and the LRT (lower pie chart), which are mainly colonized by members of the Proteobacteria, Firmicutes, and Bacteroidetes. Under physiological conditions, the respiratory tract hosts a rich and diverse microbial community (left circle). Several factors, including respiratory disease onset, farm management practices and antimicrobial treatment, contribute to reducing the bacterial diversity in the imbalance state (right circle)
