Sažetak
Caseous lymphadenitis is a chronic contagious disease of sheep and goats with a worldwide distribution. It is characterized by the formation of pyogranulomas in superficial lymph nodes and less frequently in visceral lymph nodes and organs. The etiological agent that causes the disease is Corynebacterium pseudotuberculosis. The visceral form of caseous lymphadenitis is one of the most common causes of ˝thin ewe syndrome˝. Although, caseous lymphadenitis is not a zoonosis it is important to be aware of the fact that C. pseudotuberculosis has a certain zoonotic potential. During this research, an epizootiology survey of owners and a clinical examination of 25 flocks of sheep and 8 flocks of goats from the area of the Veterinary Clinic Ozalj were conducted. In cases when caseous lymphadenitis was suspected, samples were taken and sent on bacteriological examination. During the study, abscesses were found in nine animals, but the presence of C. pseudotuberculosis was confirmed in only one goat, which gives a disease prevalence of 3 % (1/33) in the total number of examined herds, and 12.5 % (1/8) in the goat herds. Knowledge about this disease among the respondents is very scarce and raising awareness and educating small ruminant owners about this disease would help in the earlier detection of symptoms as well as its diagnosis and further suppression. On the one hand, it shows willingness of owners to actively participate in its detection and control. As a conclusion, we believe that more efforts should be made to better educate farmers about the importance of recognizing and controlling caseous lymphadenitis.
