With its epizootiological characteristics, the territory of the municipality of Belgrade city is a potentially important locality for the maintenance and spreading of a number of serovars of Leptospira interrogans. In order to evaluate the epizootiological situation as far as animal leptospirosis in the Belgrade region is concerned, from January 2012 until June 2013 the prevalence of cat leptospirosis has been evaluated. The standard microagglutination test (MAT) was used to determine animals sero positive to different serovars that belong to L. interrogans sensu lato complex. The antigens used were: Icterohaemorrhagiae, Grippotyphosa, Pomona, Canicola, Bratislava, Batavie, Sejroe, Pyrogenes, Australis and Autumnalis. Out of the total number of tested animals, there were 43 (26.7%) positive to one, two or three serovar(s). Out of a total of 43 positive sera 20 (46.5%) samples were positive to more than one leptospira serovar

Introduction: Recently in Europe an increase in the population of red deer (Cervus elaphus), roe deer (Capreolus capreolus), and fallow deer (Dama dama) has been observed. Research on the prevalence of Leptospira infections in Polish cervids has been performed for the first time.
Material and Methods: During 2014/2015 hunting season, 147 blood samples from red deer, roe deer, and fallow deer were collected. The animals originated from different geographical regions across Poland. Serum samples were tested by microscopic agglutination test (MAT) for the presence of specific antibodies to the following Leptospira serovars: Icterohaemorrhagiae, Grippotyphosa, Sejroe, Tarassovi, Pomona, Canicola, Bratislava, Hardjo, Ballum, Zanoni, Hebdomadis, and Poi.
Results: Serum antibody titres specific to Grippotyphosa, Pomona, and Zanoni serovars were found; none of the sera were positive for any of the other serovars. Out of 147 serum samples only 7 were positive, which gave an overall prevalence of 4.8% in the tested animal population.
Conclusion: The low Leptospira antibody titres along with the low number of positive serum samples in deer indicate that these animals may not act as significant reservoirs of Leptospira for either humans or animals in Poland.

Blood serum samples collected from randomly selected groups of 32 pigs and 41 cows reared in farms belonging to the rural community “A” located in eastern Poland and exposed to the Vistula river floods, and serum samples from groups of 41 pigs and 40 cows from farms belonging to the rural community “B” located also in eastern Poland but not in the area exposed to floods, were examined by the microscopic agglutination test for the presence of antibodies against 18 Leptospira serovars. The percentage of serum samples presenting positive results with at least one serovar were higher in pigs and cows from community “A” comparing to community “B” (34.4% vs. 4.9% and 26.8% vs. 15.0%, respectively). In the case of pigs, the difference was statistically significant (P=0.0015). The reactions with 12 Leptospira serovars (Australis, Bataviae, Bratislava, Canicola, Hardjo, Hebdomadis, Icterohaemorrhagiae, Pomona, Poi, Cynopteri, Grippotyphosa, Celledoni,), belonging to four species (L. interrogans, L.borgpetersenii, L. kirschneri, L. weili) were found in the examined animals. In community “B”, six reactions with one serovar and two reactions with two serovars were noted whereas in community “A” - 19 reactions with one serovar, one reaction with two serovars and two reactions with six serovars were observed. The titres in animals reared in community “A” were significantly higher (up to 25,600) compared to community “B” (up to 200, P=0.0094). The obtained results suggest that the exposure to flooding may increase the infection rate in pigs and cows from afflicted areas to some extent.
