Abstract
|
|
|
A total of 113 Staphylococcus hyicus subsp. hyicus which had been isolated from healthy and diseased pigs were examined for their ability to produce staphylococcins. For selection of staphylococcin indicator strains, 80 strains were randomly selected from 113 strains, and were tested as indicator and as donator. The 8 indicators were chosen and used to type all of the strains.
The ability to produce staphylocpccin could be demonstrated in 43 strains (38.1%) of 113 Staph hyicus subsp. hyicus. The frequency of activity was higher in diseased pig strains (44.4%) than in healthy pig strains(36.8%). 43 staphylococcin producer strains were differentiated into 10 reaction types.
The inhibitory effects of the staphylococcin (N27 and R 3) on other staphylococci differed by the staphylococcal species tested. All the gram-negative species were completely resistant to the three producing strains.
