Background. Bacterial overgrowth syndrome (BOS) is a term that describes clinical manifestations that occur when the normally low number of bacteria that inhabit the stomach, duodenum, jejunum, and proximal ileum significantly increases or becomes overtaken by other pathogens.

Secondary bacterial diseases are caused by invasion of bacteria after a predisposing condition, such as viral infections, stresses, tissue injuries, and dietary upsets.A bacterial disease may affect a single tissue or organ, or it may affect multiple tissues and organs of the animal.econdary bacterial diseases are caused by invasion of bacteria after a predisposing condition, such as viral infections, stresses, tissue injuries, and dietary upsets.
