Hookworm was a previously dominant parasitic infection in Southern Thailand. The changing population to an aging society in Yo Island has never been investigated for intestinal parasites. This study aimed to estimate the prevalence of hookworm and intestinal parasitic infections on Yo Island, a small island in Songkhla Province of southern Thailand.
A cross-sectional study was conducted among volunteers aged 15 and above to give one stool sample that was screened by wet mount for intestinal parasites and the modified Harada-Mori culture (mHMFPC) which is adapted from HMFPC, using local plastic bag containers instead of test tubes for hookworm detection.
Two hundred forty-seven volunteers (females = 160) gave one stool. The highest participation was in age group higher than 60 years. Most were Buddhism (89.1%), agriculturist (71.4%), non-education (87.9%), and income lower than 9000 baht (50.2%). The prevalence of intestinal parasites was 13/247 (5.3%) of which 6/247 (2.4%) were positive for hookworm species One volunteer was coinfected with hookworm and and another with and . The mHMFPC detected more positive stool samples than wet mount and wet mount: 5 vs. 2.
Parasite prevalence was low in this urban community of mostly low-income village dwellers. The mHMFPC appeared better at detecting hookworm but numbers were small. Combined techniques are suitable for field use.
钩虫曾是泰国南部的主要寄生虫感染。约岛人口向老龄化社会转变，但其肠道寄生虫情况从未被研究过。本研究旨在估计泰国南部宋卡府一个小岛——约岛的钩虫及肠道寄生虫感染患病率。
对15岁及以上的志愿者进行横断面研究，他们提供一份粪便样本，通过湿片法筛查肠道寄生虫，并采用改良的原田-森氏培养法（mHMFPC），该方法是在原田-森氏培养法基础上改进而来，使用当地塑料袋容器而非试管来检测钩虫。
247名志愿者（女性 = 160名）提供了一份粪便样本。参与度最高的是60岁以上年龄组。大多数人是佛教徒（89.1%）、从事农业（71.4%）、未接受教育（87.9%）且收入低于9000泰铢（50.2%）。肠道寄生虫患病率为13/247（5.3%），其中6/247（2.4%）钩虫种类呈阳性。一名志愿者同时感染了钩虫和 ，另一名同时感染了 和 。mHMFPC检测出的阳性粪便样本比湿片法多，湿片法检测出2例阳性，mHMFPC检测出5例阳性。
在这个主要由低收入村民组成的城市社区中，寄生虫患病率较低。mHMFPC在检测钩虫方面似乎效果更好，但数量较少。联合技术适用于现场使用。
