[Isolation of R-phase strains of S. senftenberg form fish meal].
Studied are being a total of 40 strains of S. senftenberg, which at the time of isolation proved to be in R-phase z43, with an antigenic formula 3,19:z43:--. Splitting of the normal S-phase gst is possible at reseeding the cultures from 5 to 10 times in semisolid 0.7 per cent agar, adding no H-antiserum. This is essential for all diagnostic laboratories as not all of them have at their disposal a monofactor antiserum z43 (the production of which is rather difficult and expensive) for inhibiting the respective R-phase.
