【摘要】 用改良加藤法和试管滤纸培养法,对漳州市郊区蕉园社员进行粪检,共检查2069人,其中钩虫感染者1402例,其感染率为67.8％。人群的钩虫感染有随年龄增长而增高的趋势,而70岁以上年龄组的感染率有所下降,这可能与参加劳动多少有关。926例钩虫幼虫培养结果,单纯十二指肠钩虫占67％,美洲钩虫占13％,两种钩虫混合感染占20％。十二指肠钩虫与美洲钩虫之比为2.6:1。表明漳州郊区系以十二指肠钩虫为主的两种钩虫混合感染地区。更多还原

【Abstract】 An investigation on hookworm infection was pursued in 4 pilot areas of Zhang-zhou, Fujian Province. Using Kato-Katz method, the mean hookworm infection rate was recorded 67.8% in 2069 people. A trend of increase of incidence with the upgrading of age was indicated, but the decline of the incidence in age group above 70 was an exception, which was attributed to the frequency of farming labor. The result of larva cultivation evidenced a proportion of 67% for Ancylostoma duodenale, 13% for Necator americanus and 20% for mixed infection. Species identification revealed a ratio of 2.6:1 for A. duodenale versus Necator americanus, demonstrating A. duodenale is the predominant species of hookworm in Zhangzhou.更多还原
