Abstract

Abstract

strains are usually defined by biological parameters such as pathogenicity in mice. A characterization of toxoplasma strains by biochemical techniques has not been reported. In this study, extracts of tachyzoites of 7 toxoplasma strains were compared on the basis of their isoenzyme patterns for 39 enzymes by means of isoelectrofocusing in polyacrylamide gels. Eighteen enzymes gave clear and reproducible bands. Of these, 14 had identical electrophoretic patterns for all strains. Two different isoenzyme types were found for the enzymes aspartate aminotransferase, glutathione reductase, glucose phosphate isomerase, and amylase. This allowed the description of 3 isoenzyme pattern groups among the 7 toxoplasma strains. The possible relationship between biological behavior and isoenzyme pattern groups is discussed.
