To date, infection by free-living amoebae has not been described in Myanmar, Laos or Cambodia. Thailand reported its 1st case of primary amoebic meningoencephalitis in 1983, and by 1987, an additional 5 cases had been reported. 22 cases were reported up to 2004: 10 due to _Naegleria fowleri_, 11 Acanthamoeba, and one _Balamuthia mandrillaris_.
A study performed during 2001 to 2004 found that amoebae accounted for
2 percent of ulcerative keratitis cases in Bangkok; and as of 2005, Acanthamoeba, Naegleria, Hartmanella, Vahlkampfia and Vannella had been identified in soil and water samples from 14 provinces. [1,2]
