title: [Group immunity against tularemia in employees of the Zelenina Processing Plant in Brno].
abstract: The authors examined, using the tularin test of Soviet make a total of 1380 employees of 14 work places of the national enterprise Zelenina in Brno. These work places are concerned with the purchasing, storage, distribution and sale of fruit and vegetables, grown among others also in South Moravian areas contaminated with tularaemia. They detected a total of 71 positive reactions concentrated mainly among long-term workers of the main storage places and transport departments of eight plants, i.e. Boskovice, Prostĕjov, Brno-town, Breclav, Trebíc, Brno-rural area, Slavkov and Znojmo, where the total tularaemia immunity rate varied between 4.88 and 12.30%. The distribution of positive cases signalizes with a high probability the occupational character of thus retrospectively detected cases, similarly as in the sugar plants and in the enterprise Fruta where products from the above area are processed. The source of infection are most probably rodents and the medium of transmission is probably fruit and in particular vegetables from the South Moravian area with tularaemia. The author recommends to introduce provisions to protect workers with risk occupations and possibly also consumers buying these products in retail shops.
