	abstract = {<p>A monoclonal antibody (MAb) produced against trophozoites of Entamoeba histolytica strain HM-1:IMSS, reacted with all of 42 isolates and 4 clones showing pathogenic zymodeme (Z) patterns, i.e., Z-II, Z-II alpha-, Z-II (glucose phosphate isomerase: gamma +), Z-VII, Z-VII (glucose phosphate isomerase: alpha lack, gamma +), Z-XI, Z-XIV, and Z-XIX, regardless of culture conditions, geographical origins, or host symptoms in an indirect fluorescence antibody test. In contrast, the MAb failed to react with 14 isolates possessing nonpathogenic zymodemes Z-I and Z-VIII and did not react with other enteric protozoan parasites, such as E. histolytica-like Laredo, Entamoeba hartmanni, Entamoeba coli, Endolimax nana, Dientamoeba fragilis, Trichomonas hominis, and Giardia lamblia. Western immunoblotting analysis showed that the molecular weight of the antigenic component recognized by the MAb was exclusively 30,000 in pathogenic isolates of different zymodemes. These results suggest that the 30,000-molecular-weight antigen is a marker of pathogenic isolates and that the indirect fluorescent-antibody test with the MAb is useful for the accurate discrimination of pathogenic amebae.</p>},
