Analysis of the stigmata of congenital syphilis in two study populations indicates that the imprints of the disease are the same, whether the patient population is of Caribbean or of North American origin. If the Columbian theory of origin of syphilis were correct, the longer syphilization of the West Indies might have tended to lessen the effects of the disease by attenuating Treponema pallidum. The presence of yaws and pinta in the West Indies may even have had an immunizing effect. The similar findings in the two population groups suggests that the events postulated by the Columbian theory did not take place.
对两个研究群体中先天性梅毒特征的分析表明，无论患者群体是加勒比裔还是北美裔，该病的印记都是相同的。如果梅毒起源的哥伦布理论是正确的，那么西印度群岛较长时间的梅毒感染可能会通过削弱梅毒螺旋体来减轻疾病的影响。西印度群岛存在雅司病和品他病甚至可能具有免疫作用。这两个人群组的相似发现表明，哥伦布理论所假设的事件并未发生。
