The presence of serum antibodies to Entamoeba histolytica was detected by indirect hemagglutination in a representative sample of the 32 federal entities of the Mexican Republic. This study was designed to include biologic, geographic, social, economic, and educational variables. The total percentage of positive sera was 8.41%. Seroprevalence varied with geographic zones, with the South Central, South Pacific, and Yucatan Peninsula areas showing the highest values (> or = 9%), and the North, Northeast, and Gulf of Mexico areas showing the lowest values (< or = 8.0%). Seroprevalence of anti-E. histolytica antibodies seemed to increase from the northern regions to the southern areas of Mexico. These results indicated that amebiasis is endemic in the Mexican Republic, with areas of high seroprevalence not related to climatic conditions. Exposure to infectious contact with E. histolytica occurred at all ages, with a higher frequency at school age.
通过间接血凝试验在墨西哥共和国32个联邦实体的代表性样本中检测到抗溶组织内阿米巴血清抗体。本研究旨在纳入生物学、地理、社会、经济和教育变量。阳性血清的总百分比为8.41%。血清阳性率随地理区域而异，中南部、南太平洋和尤卡坦半岛地区的血清阳性率最高（≥9%），而北部、东北部和墨西哥湾地区的血清阳性率最低（≤8.0%）。抗溶组织内阿米巴抗体的血清阳性率似乎从墨西哥北部地区向南部地区升高。这些结果表明，阿米巴病在墨西哥共和国呈地方性流行，血清阳性率高的地区与气候条件无关。所有年龄段的人都有接触溶组织内阿米巴感染源的情况，学龄期的接触频率更高。
