spp. are free-living amoeba found in a wide variety of natural habitats. The high percentage of the presence of in different environmental sources represents a sanitary risk for public health, especially immunocompromised patients and contact lens wearers. can cause granulomatous amoebic encephalitis, otitis, lung lesions, and skin infections in individuals with immune deficiencies. In the present study, the status of contamination of water sources in Isfahan, central Iran is analyzed through parasitological method. Totally 93 samples were utilized consisting of 59 samples of tap water and 34 samples of environmental water collected from Isfahan in May and June 2014. After filtering, cultivation was done in non-nutrient agar medium, and then the cultured media were kept at 25-30 °C. The samples were analyzed based on the morphological criteria. spp. were found in 25 (73.53 %) out of 34 environmental water samples and 17 (28.8 %) out of 59 tap water. Generally, spp. were found in 42 (45.16 %) of the samples. The results of the present study showed that the water contamination with spp. in different regions of Isfahan can be a potential infection source for at high risk people. It could be suggested that public education and precaution are quiet necessary.
某些种类是自由生活的变形虫，存在于各种各样的自然栖息地中。在不同环境来源中该生物的高出现率对公众健康构成了卫生风险，尤其是对免疫功能低下的患者和隐形眼镜佩戴者。在免疫缺陷个体中，某些种类可导致肉芽肿性阿米巴脑炎、中耳炎、肺部病变和皮肤感染。在本研究中，通过寄生虫学方法分析了伊朗中部伊斯法罕水源的污染状况。总共使用了93个样本，其中包括2014年5月和6月从伊斯法罕采集的59个自来水样本和34个环境水样。过滤后，在无营养琼脂培养基中进行培养，然后将培养基置于25 - 30°C下。根据形态学标准对样本进行分析。在34个环境水样中的25个（73.53%）以及59个自来水样本中的17个（28.8%）中发现了某些种类。总体而言，在42个（45.16%）样本中发现了某些种类。本研究结果表明，伊斯法罕不同地区被某些种类污染的水可能是高危人群的潜在感染源。可以建议公众教育和预防措施是非常必要的。 （注：原文中多次出现“spp.”，未明确具体指代，翻译时保留原样）
