A highly discriminatory multi-typing scheme for Proteus mirabilis and Proteus vulgaris Senior, B. W. and Larsson, P.,, 16, 193-202 (1983), doi = https://doi.org/10.1099/00222615-16-2-193, publicationName = Microbiology Society, issn = 0022-2615, abstract= SUMMARY Strains of Proteus mirabilis and P. vulgaris isolated in England, Scotland and Sweden were characterised by proticine production-proticine sensitivity (P-S) typing, O serotyping and Dienes typing methods. The determinants of O antigenicity were independent of those determining proticine production and proticine sensitivity. Because of this independence, the combination of P-S typing and O serotyping for the analysis of the 133 serotypable strains separated them into 81 distinct types whereas P-S typing and O serotyping methods alone separated them into only 56 and 19 types respectively. There was a relationship between the Dienes type and the P-S type; the determinants of Dienes compatibility were the proticine production-proticine sensitivity characters. The determinants of O antigenicity appeared to play no role in the Dienes reaction. Some strains that were indistinguishable by P-S typing and O serotyping methods were distinguished by Dienes typing., language=, type=
