The aim of this study was to characterise and compare Pasteurella multocida isolates originating from pigs (n = 43), calves (n = 31), rabbits (n = 27), and to a lesser extent from other hosts (n = 6). A total of 107 P. multocida isolates were obtained from various locations in the Czech Republic. They were analysed by capsular PCR typing and ribotyping, and tested for the production of dermonecrotoxin. Most frequently, serogroup A isolates (n = 74) were found, followed by serogroup D (n = 25) and serogroup F (n = 8) isolates. From a total of fifteen different ribotypes (1–15) generated by restriction endonuclease MspI, four ribotypes (1, 3, 4, and 7) were predominant. The prevalence of predominant ribotypes was different in isolates originating from different hosts. Ribotype 1 was characteristic for rabbit isolates, ribotype 3 was primarily found in pig isolates, and ribotype 7 dominated among calf isolates. Sixteen (mainly porcine) isolates produced dermonecrotoxin but significant correlation among ribotypes and dermonecrotoxin production was not observed.
