Serologic evidence of Leptospira spp. serovars in cattle in Croatia

Bovine leptospirosis occurs throughout the world, but it is most commonly in warm climates. It is economically significant disease that results in abortions, stillbirths and loss of milk production. Therefore, the implementation of surveillance and control measures is of particular importance for the suppression of this important zoonosis. According to annual orders issued by Ministry of Agriculture for years 2008, 2009 and 2010, all bulls used for natural breeding and production of semen for artificial insemination must be serologically tested for leptospirosis twice each year. In addition, all cases of abortion in cattle must be reported and blood of each animal serologically tested for leptospirosis. Also according croatian legislation, after treatment we carry out serological blood tests twice at intervals of 21 days after completion of treatment. During the year 2008. 3024 (485 positive) cattle blood samples were tested for leptospirosis, in 2009. 3150 (538 positive) blood samples and 5373 (475 positive) in 2010. All sera were tested by microscopic agglutination test (MAT) for the presence of 12 leptospiral antigens. As antigens for testing the sera were used serovars (sv.): sv. icterohaemorrhagiae – RGA, sv. ballum – Mus 127, sv. australis – Ballico, sv. pomona – Pomona, sv. grippotyphosa – Moskow V, sv. sejroe – M84, sv. saxkoebing – M24, sv. tarassovi – Perepelicin, sv. canicola – Hond Utrecht IV, sv. bataviae – Van Tienen, sv. hardjo – Hardjoprajitno and sv. hardjo – Hardjo-bovis. An initial sera dilution of 1:100 was considered as a cut-off point for a positive reaction. In 2008. the highest prevalence had Osijek-Baranja 126 (26%), Sisak-Moslavina 108 (22.3%), Vukovar-Srijem 71 (14.6%) and Varaždin 48 (9.9%) counties. In 2009. the highest prevalence had Sisak- Moslavina 236 (43.9%), Zagreb 92 (17.1%), Bjelovar-Bilogora 46 (8.6%) and Pozega-Slavonia 38 (7.1%) counties. In 2010. counties with the the highest prevalence were Pozega-Slavonia 154 (32.4%), Osijek-Baranja 80 (16.8%), Bjelovar-Bilogora 75 (15.8%) and Sisak-Moslavina 72 (15.2%). Positive reactions for leptospirosis during the study period were not found in the Dubrovačko-neretvanska, Lika-Senj, Primorje-Gorski Kotar and Zadar County. The most frequent serovars in cattle during the three years were sv. hardjo (22.32%), sv. sejroe (22.32%), sv. saxkoebing (21.93%) and sv. hardjobovis (21.38%). Results indicate that the cattle in the continental part of the Croatia due to leptospirosis natural foci (Lonjsko Polje i Kopački rit) and the joint holding cattle, pigs and horses in the same area are exposed to leptospira infection more than animals from the croatian coast. In order to control the spread of disease within the same breeding and on the other breedings it is necessary to continue to control the disease, treat breedings with the aim of reducing the carrier state, as well as to the availability, change management to reduce the possibility of re-infection.
