Isoenzymes of phosphoglucomutase and hexokinase were repeatedly evaluated using starch gel electrophoresis in polyxenic cultures of Entamoeba histolytica. In two out of 18 strains spontaneous changes of isoenzyme patterns were recorded. While originally they were categorized into virulent group of zymodemes, following isoenzyme analysis classified them as non-virulent. The relation between virulence and isoenzyme pattern is questionable.
Résumé
Les isoenzymes PGM et HK ont été évaluées sur plusieurs générations par électrophorèse sur gel d’amidon de cultures polyxéniques de Entamoeba histolytica. Deux souches sur 18 présentent un changement de profil isoenzymatique. A l’origine ces souches ont été classées dans le groupe virulent selon les zymodèmes, alors que les souches correspondantes des autres générations sont classées comme non-virulentes. La relation entre la virulence et le profil isoenzymatique est remise en question.
