Virus canine coronavirus and canine parvovirus, the two leading causes of viral diarrhea, have now joined forces to cause acute diarrhea that can lead to death in puppies and dogs. This phenomenon of two or more infectious agents combining in the intestinal tract to cause more severe symptoms is often referred to as the “enteritis complex,” veterinarians have recently discovered.
Parvovirus is a highly contagious disease which causes severe diarrhea, vomiting and often leads to death. Coronavirus, the second leading cause of viral diarrhea, is being diagnosed more often. This disease affects dogs of all ages but is most severe in puppies. Symptoms include diarrhea, vomiting, excessive thirst, weight loss, listlessness and loss of appetite.
Coronavirus, while not a new virus, is difficult to diagnose, requiring new sophisticated techniques involving electron micropsy and/or immunofluorescence. Coronavirus can occur simultaneously with parvovirus to cause even more severe symptoms which lessens the chance of recovery.
Preliminary studies conducted by Cornell University indicates that coronavirus is playing a more important role in the infectious canine enteritis complex than previously thought. This study demonstrated that a dual infection''«f both coro* navirus and plttVbWrttS canproduce acute viral diandiMk-with a 100 percent mortality rate.
