This study was carried out to determine the presence of Entamoeba histolytica in water sources of Niğde province in Turkey, between June and November 2021.
A total of 90 water samples were taken from 15 different water sources (drinking water, well water, spring water, wastewater and dam water) every month and the presence of E. histolytica antigens in the samples was examined by ELISA.
The positivity for E. histolytica was determined in 7 (7.7%) of 90 samples. While no antigens were found in any of the samples in June and September, E. histolytica was positive for three samples (20%) in July, one sample (6.6%) in August and October and two samples in November (13.3%). One of 24 dam samples (4.1%), 1 of 12 wastewater samples (8.3%), 1 of 12 well samples (8.3%), and 4 of 24 fountain samples (16.6%) that examined by ELISA were found positive. On the other hand, none of the examined 18 spring samples were positive. In addition, 4 (8.8%) of 45 samples that examined in summer and 3 (6.6%) of 45 samples that examined in autumn were detected positive by using ELISA. Entamoeba histolytica positivity in samples was statistically insignificant in terms of months, water resources and seasons (P > 0.05).
As a result, the presence of E. histolytica, which is an important public health problem in water sources, was determined for the first time in Niğde province of Türkiye with this study.
本研究旨在 2021 年 6 月至 11 月期间，确定土耳其尼代省水源中是否存在溶组织内阿米巴。
每月从 15 个不同水源（饮用水、井水、泉水、废水和水坝水）中采集 90 份水样，并通过 ELISA 检查样品中溶组织内阿米巴抗原的存在。
在 90 份样本中，有 7 份（7.7%）检测出溶组织内阿米巴阳性。6 月和 9 月的所有样本均未检出抗原，7 月 3 份样本（20%）、8 月和 10 月 1 份样本（6.6%）、11 月 2 份样本（13.3%）检测出溶组织内阿米巴阳性。通过 ELISA 检查的 24 个水坝样本中有 1 个（4.1%）、12 个废水样本中有 1 个（8.3%）、12 个井水样本中有 1 个（8.3%）和 24 个喷泉样本中有 4 个（16.6%）呈阳性。另一方面，检查的 18 个泉水样本均为阴性。此外，通过 ELISA 检测，夏季采集的 45 个样本中有 4 个（8.8%）、秋季采集的 45 个样本中有 3 个（6.6%）呈阳性。样本中溶组织内阿米巴的阳性率在月份、水源和季节方面无统计学意义（P>0.05）。
本研究首次在土耳其尼代省确定了水源中存在溶组织内阿米巴，这是一个重要的公共卫生问题。
