The dominant intestinal helminths in the Iranian villages of Kargar Malleh (hookworms), Bandar Abbas (hookworms) and Jazin (Ascaris lumbricoides and Trichuris trichiura), were recorded with their frequency distributions, in 80, 40 and 111 villagers, respectively in 1977-78. Anthelminthics were then used to remove all intestinal stages which were identified and counted. Analyses showed clumped or over-dispersed patterns in all cases. Each community contained 'wormy persons', 1 to 3% of the individuals carried 11, 16, 30, 38 or 84% of all the worms collected. 'Wormy persons' could only be identified for one parasite, thus those with the highest infestations of one species were not prone to higher infestation with another. In Jazin, 111 persons with measured initial worm burdens of A. lumbricoides, T. trichiura and Trichostrongylus spp. were followed without further therapy or change in habits for up to 12 months during re-infection. There was no significant correlation between those persons with high initial worm burdens and those with high burdens after 12 months. The public health significance of these findings is discussed.
1977 - 1978年，分别在卡尔加尔·马勒（钩虫）、阿巴斯港（钩虫）和贾津（蛔虫和鞭虫）这几个伊朗村庄中，记录了80名、40名和111名村民体内主要的肠道蠕虫及其频率分布情况。随后使用驱虫药清除所有已识别并计数的肠道阶段的蠕虫。分析表明，在所有案例中均呈现聚集或过度分散的模式。每个社区都有“蠕虫携带者”，1%至3%的个体携带了所收集到的全部蠕虫的11%、16%、30%、38%或84%。“蠕虫携带者”仅针对一种寄生虫被识别出来，因此，一种寄生虫感染程度最高的人并不容易感染另一种寄生虫。在贾津，对111名蛔虫、鞭虫和毛圆线虫初始蠕虫负荷量已测定的人，在再次感染期间，未进行进一步治疗或改变生活习惯，随访长达12个月。初始蠕虫负荷量高的人与12个月后蠕虫负荷量高的人之间没有显著相关性。本文讨论了这些发现的公共卫生意义。
