Arcanobacterium haemolyticum is rarely isolated from clinical),material either in human or veterinary medicine. As for our country, there is only one official report with regard to the isolation of A. haemolyticum from material of animal origin. Pathologically altered parts of the lungs from piglets with pneumonic symptoms, were streaked aerobically and microaerophilically and the suspect colonies were tested with a double CAMP test. The positive inverse CAMP with Staphylococcus aureus and synergistic haemolysis with Rhodococcus equi prompted us to direct our investigations to A. haemolyticum. The API Coryne Bio Merieux set was used to make the diagnosis and later evaluated using a software programme from the same manufacturer. The diagnosis was: Arcanobacterium haemolyticum with an identity probability of 99,9 % and 7= 0,75. The only departure from the identification table was recorded for a -glucosidase, which was negative in all the tested isolates
