Results of investigations carried out between 1996 and 2000 are summarised. Bacteriological examinations of porcine lung samples yielded positive results in 59.4 % of the tested animals. The most frequently isolated species was Actinobacillus pleuropneumoniae (mostly serotype 9) alone or in combination with Pasteurella multocida. Resistance to tetracycline was demonstrated in 40.4 and 22.6 % of the serotypes 9 and 2, respectively. The corresponding proportions for penicillin were 36.3 % (serotype 9) and 16.1 % (serotype 2). Infections by more than one serotype were demonstrated in some herds.
