Ok 0 y e J. O. A., U c he U. E.: S~ologieal Evidenee 06 In6ecUo1L6 8wL.\a.t. VLlelMle VLw.6 In6ecUon in Wad Rw. Acta Vet. Brno. 55, 1986: 207-209. A total of 23 wild rats (Rattu6 ~) were caught dead by traps set in 4 different poultry farms with history of outbreak of infectious bursal disease (IBD). The internal. organs were suspended in phosphate buffered saline (PBS) and assayed for IBD precipitins and antigens by agar gel diffusion precipitation test (AGDT). Six samples were positive for pre-cipitins. These observations indicate that IBD virus multiples in wild rats and these rats may play some role in the spread of the disease among poultry farms.
