An update on aspects of viral gastrointestinal diseases of dogs and cats.

摘要: Viruses commonly cause gastrointestinal illnesses in dogs and cats that range severity from mild diarrhoea to malignant neoplasia. Perpetual evolution of viruses is reflected changing disease patterns, so familiar are sometimes discovered new or unexpected diseases. For example, canine parvovirus (CPV) has regained the ability infect felids a panleucopenia-like illness. Feline panleucopenia virus (FPV) been shown “fading” young kittens recently implicated as possible feline idiopathic cardiomyopathy. Molecular scrutiny viral diseases permits deeper understanding pathogenesis epizootiology. lymphomas have not, past, strongly associated with retroviral infections, yet some these tumours harbour proviruses. leukaemia (FeLV) may play role lymphomagenesis, even diagnosed uninfected using conventional criteria. There strong evidence immunodeficiency (FIV) can also be oncogenic. The variant coronaviruses invariably-fatal infectious peritonitis (FIP) arise by sporadic mutation an ubiquitous only mildly pathogenic enteric coronavirus (FECV); finding substantial management implications for cat breeders veterinarians. Conversely, (CECV) shows considerable genetic antigenic diversity but causes mild, self-limiting puppies. Routine vaccination against this not recommended. Although parvoviruses, retroviruses most important known disease, other role. rotaviruses combined human produce new, reassortant, zoonotic viruses. Some companion animal humans directly. Undoubtedly, further await discovery. KEY WORDS: Parvovirus, panleucopenia, coronavirus, retrovirus, virus, enteritis, lymphoma, rotavirus, torovirus, dog, cat,
