| Abstract: | As a result of immunological examination of 658 domestic ducks of 6 poultry farms and 269 doves caught in Vilnius, antiornithosis antibodies were revealed in 3.1 +/- 0.7% of ducks and in 36.4 +/- 2.9% of doves. They were also found in 20 of 34 wild waterfowl. The causative agent of ornithosis was isolated in virological examination of the organs of a coot. Ornithosis nature of an epizootic outbreak among ducks of a poultry farm was proved by virological examination. The population was examined immunologically (2285 persons) and by intradermal test with the ornithosis antigen (80 persons). Positive specific reactions were revealed in 32.6% of persons engaged in poultry tending, and in 7.6% of other rural population. A case of ornithosis in man engaged in fowling (of doves) for their examination is described. |
