Abstract

The present study was aimed at investigating the coexistence and interactions between free living amoebae of Naegleria and Hartmannella genera and pathogenic Legionella pneumophila bacteria in thermal saline baths used in balneotherapy in central Poland. Water samples were collected from November 2010 to May 2011 at intervals longer than 1 month. The microorganisms were detected with the use of a very sensitive fluorescence in situ hybridisation method. In addition, the morphology of the amoebae was studied. Despite relatively high salinity level, ranging from 1.5 to 5.0 %, L. pneumophila were found in all investigated baths, although their number never exceeded 10(6) cells dm(-3). Hartmannella were not detected, while Naegleria fowleri were found in one bath. The observation that N. fowleri and L. pneumophila may coexist in thermal saline baths is the first observation emphasising potential threat from these microorganisms in balneotherapy.

摘要

本研究旨在调查波兰中部温泉浴场中自由生活的纳格尔虫属和嗜热泉古虫属阿米巴虫与致病性嗜肺军团菌之间的共存和相互作用。水样于 2010 年 11 月至 2011 年 5 月间采集,采集间隔超过 1 个月。使用非常敏感的荧光原位杂交法检测微生物。此外,还研究了阿米巴虫的形态。尽管盐度相对较高,范围在 1.5 至 5.0%,但在所有调查的浴池中均发现了嗜肺军团菌,尽管其数量从未超过 10(6)细胞/dm(-3)。未检测到嗜热泉古虫,而在一个浴池中发现了福氏纳格尔虫。嗜肺军团菌和福氏纳格尔虫可能在温泉浴场中共存的观察结果首次强调了这些微生物在温泉疗法中的潜在威胁。
