title: The Dienes phenomenon: identification of the determinants of compatibility.
abstract: Two hundred and four isolates of swarming strains of Proteus species which had been typed for their ability to produce bacteriocin (proticine) and also their proticine sensitivity (P/S typing) were tested in all combinations for their Dienes compatibility with each other. Ninety-eight distinct Dienes compatibility groups were found. Physiological and genetic experiments supported the evidence of typing results that, irrespective of species, both the type of proticine a strain produces (P type) and the sensitivity of the strain to proticine (S type) were determinants of Dienes compatibility. Strains showing compatibility in the Dienes test were of the same P/S type, whereas those of different P/S types were incompatible.
