The latest literature data concerning canine corona and rotavirus enteritis are summarised. Canine coronavirus was first isolated from feces of military dogs In 1971. CCV is fairly widespread throughout the canine population with up to 80% of adult dogs having serologic evidence of exposure. Dogs are infected via fecal-oral route. CCV is highly contagious and spreads rapidly through groups of susceptible dogs. Neonatal pups are more severely affected than those of weaning age and adult dogs. Inapparent infection often occures. The incubation period for CCV following oral infection ranges from 1-4 days. CCV attacks the mature epithelial cells on the tip of intestinal villi resulting In villous atrophy and fusion. Dogs can have CCV and canine parvovirus simultaneously, CCV infection makes CPV infection more severe. Infected dogs usually have mild to moderate diarrhea, which is very malodorous, orange in color, and sometimes contains blood. Morbidity and mortality are low. The detection of CCV In fresh feces can be done by EM, ELISA and PCR. Serum ELISA test for CCV antibody has also been developed. Treatment is only supportive, and aims primarily at the correction of dehydration secondary to diarrhea. Broad-spectrum antimicrobial agents can be given to treat secondary bacterial infections. The principles of therapy are the same as in the case of parvoenteritis. Inactivated and MLV vaccines are available for protection against CCV infection. CCV is a major factor in enhancing CPV pathogenicity, vaccinating dogs against CCV would be important not only to protect them from CCV infection but from dual infection as well. Canine rotavirus enteritis was first described in 1980. CRV is widespread throughout the canine population, most adult dogs have serologic evidence of exposure. Clinical disease has been reported primarily in puppies less than 6 weeks of age. Most natural infections are apparently either subclinical or cause only mild diarrhea, anorexia and lethargy. Diagnosis is based on an increase in serum rotavirus antibody titers in paired samples, or by identification of the virus through EM or by an ELISA system on the feces. Supportive care is the only treatment necessary. No vaccine is currently available against canine rotavirus.
