title: [Relation between the incidence of antibodies against Leptospira interrogans in working dogs and in free-living small mammals].
abstract: Three localities were chosen in the borderland of the South Bohemian Region to investigate the problems and relations (if there are any) between the incidence of antibodies to Leptospira interrogans (L. i.) in wild ground small mammals and dogs moving in the same environment. In these regions, service dogs work as border guards every day. Blood samples of dogs at these localities were taken at about three-month intervals (from the June 1982 to the October 1984) to investigate the antibodies to L. i. serovars. Parallelly, wild ground small mammals and wild birds were caught at the same localities to be subject to the same examinations. A close relationship between the incidence of L. i. antibodies in ground small mammals and in service dogs was demonstrated at all three localities. At localities no. 1 and 2, the serovar grippotyphosa was found to be dominant in service dogs, which was also found in small rodents. On the other hand, the serovar icterohaemorrhagiae dominated in service dogs at locality no. 3. When changes in the incidence of L. i. antibodies were studied in service dogs and in wild small mammals, the peak of incidence at localities 1 and 2 was in the other half of the year; this relates to the usual maximum incidence in the natural reservoir of the serovar grippotyphosa, i.e. in rodents. On the contrary, at the third locality the peak of incidence of L. i. antibodies was recorded in the winter 1983-1984.(ABSTRACT TRUNCATED AT 250 WORDS)
