This Rotavirus is widespread in pig populations. It is present in most if not all pig herds with virtually a 100% sero-conversion in adult stock. A further epidemiological feature is its persistence outside the pig where it is resistant to environmental changes and many disinfectants. Maternal antibodies persist for 3-6 weeks after which pigs become susceptible to infection but exposure does not necessarily result in disease. It is estimated that only 10-15% of diarrhoeas in pigs are initiated by a primary rotavirus infection. In a mature herd disease appears after piglets are 7 to 10 days of age. It becomes progressively less important with age. However if pathogenic strains of E. coli are present severe disease can occur with heavy mortality.
Rotaviruses are a mayor cause of diarrhoea in intensively reared farm animals throughout the world. The clinical signs, diagnosis and epidemiology of disease are similar in all species. Its severity ranges from subclinical, through enteritis of varying degrees, to death. Disease is usually seen only in young animals, 1-8 week old, but rarely during the first week after birth.
The use of diagnosis methods permits to determinate the presence of antibodies to Rotavirus in serum of the infected animals.The kit is based on an indirect enzymatic immunoassay (Indirect ELISA).
