S. Gatti et al., FIRST ISOLATION AND CHARACTERIZATION IN HUMANS OF ENTAMOEBA-HISTOLYTICA (LABORATORY-MADE) ZYMODEME-XX, Parasitology research, 83(7), 1997, pp. 716-718
Isoenzyme analysis by starch-gel electrophoresis has proved to be a us
eful method for the biochemical differentiation of pathogenic Entamoeb
a histolytica and non-pathogenic E. dispar isolates, Of the 24 known z
ymodemes, 3 are laboratory-made and have not previously been identifie
d in humans. Parasitology screening was carried out in a psychiatric i
nstitution. Two amebic stocks were isolated and characterized that had
never previously been found in humans and that have protein patterns
identical to that of the laboratory-made zymodeme XX.
