Some pepole are look normal, and were found abnormalities on physical examinations. Others were sever ill, some of them died. On examing the samples taking from lung or liver punctures, bronchioloalveolar lavage fluid(BLF), faeces, urine,and blood, we found single celled parasites which showing various forms, which caused tissue necrosis. With PCR technique, the amplified fragment proved to be Acanthamoeba sp., having highly similarity(99%) with A. griffini, and A. polyphagus, on sequence alignment. Microscopically, parasites in the samples had morphological diversity. Those with forms inconsistant with Acanthamoeba sp. had not been identified.
