An investigation (clinical, immunological and epidemiological) of the workers of various fowl-farms was carried out in various regions of Kazakhstan for a number for years; the sera of domestic fowl and birds was studied as well. On the basis of examination of 6264 persons the greatest percentage of ornithosis was revealed among the workers of the slaughter house and the shop for the processing of the fowl. Examination of 4749 sera of bird blood showed that the highest incidence of ornithosis was among doves and ducks (43.2 and 11.6%), and the least--in chickens (5.3%); there proved to be a direct relationship between the infection of man and birds. Thus, it was shown that domestic fowl and also doves served as the source of ornithosis infection; foci of ornithosis were revealed in a number of Kazakhstan regions as a result of these investigations.
多年来，在哈萨克斯坦的各个地区对不同家禽养殖场的工人进行了一项调查（临床、免疫学和流行病学方面）；同时也研究了家禽和鸟类的血清。在对6264人进行检查的基础上，发现屠宰场和家禽加工车间的工人中患鸟疫的比例最高。对4749份鸟类血液血清的检查表明，鸟疫发病率最高的是鸽子和鸭子（分别为43.2%和11.6%），最低的是鸡（5.3%）；事实证明人与鸟类的感染之间存在直接关系。因此，表明家禽以及鸽子是鸟疫感染的来源；通过这些调查，在哈萨克斯坦的一些地区发现了鸟疫疫源地。
