[Results of serological surveys for leptospirosis in animals and people in the environs of 2 water reservoirs in eastern Slovakia].

The authors present the results of serological surveys for leptospirosis in rodents, cattle and humans, carried out in the vicinity of two large water reservoirs in Eastern Slovakia. Of the total number of 243 rodents covered by the surveys, 8.2% yielded positive reactions with leptospiral antigens. In most cases the sera reacted with L. grippotyphosa and L. sejroe . Of 168 samples of cattle serum, 13 serum samples, i.e. 7.7.%, yielded positive reactions, also with L. sejroe and L. grippotyphosa. In the group of serum samples obtained from humans, 28 out of 876 samples studied in the surveys, i. e. 3.1%, were positive. Among humans 6 serotypes were established; of these, L. sejroe occurred most frequently among humans, and also among domestic animals and rodents, then followed L. bratislava and L. grippotyphosa. The positive results obtained in humans, cattle and rodents with the prevalence of the same serotypes indicate the existence of close contacts of humans with animals, as well as the possibility of acquiring water-borne infection in recreation zones.
