Caseous lymphadenitis is a chronic contagious disease of sheep and goats with a worldwide distrubution. It is characterized by the formation of pyogranulomas in superficial lymph nodes and less frequently in visceral lymph nodes and organs. The aethiological 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 epizootiological 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, smples were taken and sent on bacteriological examination, which was carried out at the Department of Microbiology and Infectious Diseases at the Faculty of Veterinary Medicine in Zagreb. The aim of this study was to determine the presence and prevalence of caseous lymphadenitis in herds of small ruminants in the field covered by Veterinary Clinic Ozalj. 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. It is important to note that a survey conducted among sheep and goat owners found complete lack of awareness about the existence of this disease and the zoonotic potential of its causative agent. 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.
