Enzymo-Serological Comparison of Proteolytic Enzymes Produced by Salmonella Species and Other Enterobacteria

Acta Veterinaria Scandinavica volume 10, pages 225–233 (1969)Cite this article

Summary

The proteolytic enzymes produced by 11 Salmonella species of the Sub-genera I, II and IV, have been compared by a so-called enzymo-serological procedure. In sub-genus I, the enzymes of S. schleissheim and S. abortus-bovis showed an identical, or closely related, serological picture, whereas S. texas was serologically distinct.

All the 7 examined strains of sub-genus II produced proteolytic enzymes which were serologically very similar, or identical. No enzymo-serological cross-reactions were observed between these organisms and the members of sub-genus I. The only examined species of sub-genus IV, S. argentina, was enzymo-serologically distinct from all other species.

Intergeneric cross-reactions occurred between the enzymes from Salmonella species, Enterobacter (Aerobacter) cloacae and Serratia marcescens. The significance of these cross-reactions is discussed.
