Examining of blood samples on leptospirosis were carried out at big public
property farms located in four Belgrade municipalities: Palilula, Surcin,
Zemun, Obrenovac, as well as in private sector which, besides the above
mentioned, included the additional five municipalities: Mladenovac, Grocka,
Cukarica, Zvezdara and Lazarevac. Research on leptospira infections in cattle
was carried out in the period from 2000. to 2010., at the territory of
Belgrade. Serological examination of 123.971 cattle blood samples was done.
The number of seropositive animals was 1.132 (0.91%). The biggest number of
seropositive samples was noticed at Palilula (498), then in Surcin (245),
Obrenovac (183), Zemun (177), and the least, only two in Zvezdara
municipality. In the cattle, serovariety Leptospira grippotyphosa found in
459 blood samples (40.54%) dominated, then came Leptospira
icterohaemorrhagiae 356 (31.44%), Leptospira pomona 258 (22.79%), Leptospira
bataviae 53 (4.68%) and Leptospira hardjo 6 (0.53%). In cattle blood serums
no specific antibodies against L.canicola, L.serj?e and L.australis were
determined. Titre height of antibodies against leptospires ranged from 1:100
to 1:300000. Examining of cattle blood serums showed that the percentage of
infected aminals ranged from 2.82 to 0%, what globally is not a significant
percentage for this infection. Observing the disease course of spreading, it
can be noticed that it has been decreasing since 2000. when it was at its
peak (2.82%), what can be the result of a continual control, as well as of
measures that are conducted with the aim of eradication the zoonosis.
