This work presents the results of findings for brucellosis in wild boars and domestic swine in two regions of Croatia. In the region of Djakovo the blood samples of 211 wild boars were analysed and in 29.4% of the samples serologically positive reactions were established. In the same region the blood samples of 1080 domestic swine on pastures were also analysed and positive serological reactions were established in 12.3%. In the regions around Lonjsko Polje the blood samples of 53 wild boars were analysed and in 22.6% of them positive serological reactions were established. On several locations around Lonjsko Polje the blood samples of 901 domestic swine were serologically analysed and 13.5% of the swine were found to be seropositive. Bacteriological analyses of submitted materials from 24 wild boars resulted in isolation of <i>Brucella</i> from seven (29.2%) samples, and from 43 samples originating from domestic swine that had aborted and had been serologically positive, <i>Brucella</i> were isolated from 25 (58.1%) swine, as well as from 10 (62.5%) out of 16 aborted piglets. In all the isolates <i>Brucella</i><i>suis </i>biovar 2 was identified. Wild boars are carriers and reservoirs of <i>Brucella</i><i>suis </i>biovar 2 in Croatia.
