Bangkok: Faculty of Tropical Medicine, Mahidol University; 2004. p.226.There are many natural hot springs widely in scattered localities in Thailand. Since, there may be possible risks of exposure to harmful agents. We, therefore, studied contamination of free-living amoeba in 79 sites of natural hot springs from 13 provinces namely; Lop Buri, Phetchabun, Kamphaeng Phet, Uthai Thani, Trang, Phatthalung, Nakhon Si Thammarat, Surat Thani, Rayong, Phang-Nga, Chumphon, Krabi, and Satun. Phthogenic free-living amoebae of the genera Naegleria and Acanthamoeba which can cause central nervous system infection wree found in 48.1% (38/79). Since natural hot springs are popular tourist attraction the health authourities concerned should be aware of those possible hazards and provide tactful measures and guidelines to ensure safety without causing undue alarm to foreign and Thai tourist.engMahidol UniversityAmoebaContaminatedProceeding Poster
