Bacterial enteritis in dogs and cats: diagnosis, therapy, and zoonotic potential.

A variety of bacteria are known or suspected of being able to cause enteritis in dogs and cats. Campylobacter spp, Clostridium difficile, Clostridium perfringens, and Salmonella spp are most commonly implicated, but many other organisms are likely involved. Poor understanding of the intestinal microflora and the fact that many, if not all, of these microorganisms can also be found in healthy individuals complicates testing, thereby affecting the use of specific treatments and assessment of potential infection control and zoonotic disease risks. An understanding of the strengths and limitations of various diagnostic options is important for the management of canine and feline enteritis.
