title: Prevalence of ornithosis and other Chlamydia-like infections in the Ukrainian SSR.
abstract: The prevalence of ornithosis and other Chlamydia infections among various groups of the population, some species of birds and mammals was studied in several regions of the Ukrainian SSR. Among the town population having no occupational contact with domestic fowl and farm animals, complement-fixing antibodies to group ornithosis antigen were found in 6.5% of the examined, among the inhabitants of rural localities in 8.4% and among the workers of poultry farms in 19.9%. During the examination of the immunological state of the workers of cattle-breeding farms, antibodies were detected in 15.1%. Pigeons, hens and ducks were investigated as probable sources of infection. The number of positively reacting individuals was 53.7, 13,7 and 24.9%, respectively. This indicates that they play a role in the spread of infection. The obtained data point out a considerable spread of Chlamydia infections among farm animals. Positive results of serological examination were recorded in pigs in 25.7%, in calves in 15.1% and in 8.6% of cases examined.
