Summary: In the paper the findings of leptospira antibodies in swine of four biocenoses and in cattle of two biocenoses are presented as well as in small terrential mammals from their environment.Antibodies were faund in 3318 swinw out of 12566 examined and in 174 cattle out of 1010 examined.Out of 536 small mammals examined the antibodies werw found in 106 and 47 were established as carriers.In 436 cattle of I biocenosis antibodies for sv.gripp.were found in 56 and in 3 small terrential mammals out of 151 examined.Out of 574 cattle of biocenosis II antibodies for sv.icterohaemorr. were found in 4, 56, 45 and sej.and 2 of them.In 3O small terrential mammals antibodies for sv.pom.were found in one of them and 2.In 3685 swinw in biocenosis I antibodies for sv.icterohaemorr.were found in 695,pom.in6, 619, 26 and ball.and one of them.In 151 small terrential mammmals serovar for icterohaemorr.was found in 72 of them,ball.in4, 6, 5 and aust.and 1 1671 swine of biocenosis II antibodies for sv.icterohaemorr.were found in 39 of them and 5.In 100 small terrential mammals examined antibodies forsv.icterohaemorr.were found in7,aust.and 5 respectively,hardjo in 4,can.,ball.,gripp.,sej.and 3 and 2 of them.In 4889 swine of biocenosis III antibodies for sv.icterohaemorr.were found in 451,pom.in311, 712, 832, 3 sej. and 2 and gripp.and 1 of them.In 113 small terrential mammals antibodies for sv.pom.were found in 12 of them,for 4,bat.and 2 respectiveli,and icterohaemorr.in1.In 2323 swine of biocenosis IV antibodies for sv.icterohaemorr.were found in 119 of them, 64, 184 and 22 of them.In 47 small terrential mammals antibodies for sv.pom.were found in 3 two of them. Comparing the anibody findings for serovar in cattle and small terrential mammals it iis evident that antibodies for sv.hardjo and icterohaemorr.were not found in small terrential mammals. Antibodies for sv.can.were found in swine but not in small terrential mammals where antibodies for sv.hardjo were found,which however were not found in swine ,and also the same sv.leptospirosis were not present in all biocenosis.The findings of same antibodies for sv.leptospires in cattle,swine and small terrential mammals indicate that the infection was transferred from one species to another,which was supported by the findings of carriers in small terrential mammals.

Research goals: In endeavoring to eradicate contagious diseases in domestic animals or at least minimize their outbreaks,it can happen that the results wished cannot be always achieved.In some cases the cause lies in the connection between game,the carrier of the contagious disease,and domestic animals.That means that the infection in wild animals in one biocenosis could effect the incidence and spreading of infective disease in domestic animals. Hence,the chain of transferring the carrier of the disease is maintained muttualy by domestic and wild animals.One of such diseases is also leptospirosis.Although it is well known that domestic and wild animals are the carriers of leptospirosis, it is not known to which extent in particular biocenoses wild animals influence the incidence and spreading of leptospirosis in domestic animals and whether the same sv.leptospires occur by them.In our country leptospirosis is spread in breedings of domestic animals.The percentage of infected animals even exceeds 30%.The varieties of sv.leptospires incidence in particular breedings make the control even more difficult.It can happen that in breedings infected with one serovar another infection occurs and an explanation can hardly be found.For that reason despite the precautions taken for preventing the incidence and spreading of the infection in breedings the infection cannot be eradicated. Our aim is to continuously monitore the presence of antibodies for leptospires in cattle and swine breeding.After that,to establish the presence of antibodies of leptospires in small terrential mammals living in the area where domestic animal are kept,and to isolate leptospires from their organs.By continuous monitoring one biocenosis we could get a picture on the frequency of leptospirosis in them and their identity or dissimilarity in particular species.By this investigation a cognition could be reached on which furter strategy for protection of domestic animals from leptospirosis could be based.
