Učestalost goveđe enzootske leukoze u jugoistočnoj Bugarskoj tijekom razdoblja od 1998. do 2000.

During the period 1998-2000, 200518 individual bovine blood sera were tested using the immunodiffusion test for detection of antibodies against the bovine leukosis virus in South-eastern Bulgaria. The results showed that this infection was widespread – 17.02% on average (from 2.78% in the region of Haskovo to 33.07% in the region of Burgas). Those data are evidence that enzootic bovine leukosis is an important epidemiological problem in the light of new conditions for the development of cattle breeding. The incidence of enzootic bovine leukosis must be limited and eventually eradicated through strict execution of the national EBL eradication programme.U razdoblju od 1998. do 2000. pretraženo je 200518 uzoraka seruma metodom imunodifuzije radi dokazivanja protutijela za virus goveđe enzootske leukoze u jugoistočnoj Bugarskoj. Rezultati su pokazali da je zaraza proširena u prosječno u 17,02% goveda (u rasponu od 2,78% na području Haskova pa sve do 33,07% na području Burgasa). Ovi podaci potvrđuju da bolest predstavlja veoma važan epizootiološki problem posebice u uvjetima suvremenog uzgoja goveda. Za suzbijanje i iskorjenjivanje bolesti važno je provoditi sve propisane programe
