An evaluation of the API ZYM system as a means of classifying spirochaetes associated with swine dysentery

Abstract

Thirty-one strains of spirochaetes from pigs and two strains from poultry were tested in the API ZYM enzyme system. The spectrum of enzymatic reactions provided a means of differentiating between strains related to swine dysentery and strains not so related from pigs. The numerical coding system simplified the interpretation of the results.
