Biochemical and molecular characterization of a strain KA/S2 of Acnnthamoebc castellanii isolated from Korean soil

카스텔란니가시아메바(Acanthamoeba castellanii) 한국 토양분리주 KA/S2의 생화학적 및 분자생물학적 특성

A strain, KA/S2, isolated from Korean soil and morphologically assigned to Acanthcmoebc cQsteLlcnii, was characterized by isoenzyme analysis , and total proteins profile, End mitochondrial (Mt) DNA restriction fragment length polymorphism (RFLP) , and compared with four reference strains assigned to the species (the authenitic Castellani, Neff, Ma, and Chang strains). It was found that four isoenzyme, total proteins, and Mt DNA RFLP patterns by eight restriction endonucleases of the strain KA/S2 were identical with those of the Neff strain, isolated from soil of California, USA. The Chang strain was unique in its morphology and total protein patterns. Interstrain polymorphisms of isoensyme profiles and Mt DNA RFLP patterns were observed among the Castellani, Neff, Ma, and Chang strains. Mt DNA RFLP was confirmed to be highly appropriate for the strain characterization and identification of Acnnthamoeba spry.

형태적으로 Aconaqmoebcusteuon리로 동정된 한국토양분리주 KA/S2의 일부 특성을 파악하여 A. castellanii로 알려진 4가지 reference 주(Castellani, Neff, fna 및 Chang주) 와 비교하였다 K4/s2주의 mitochondria(Mt) DNARFLP와 isoelectricforusing(IEF)로 분석한 동위효소 양상은 California 토양에서 분리된 Neff주의 그것과 동일하였으나 고 외의 주들 사이에는 심한 다양성이 과찰되었다. Chang주의 형태 및 전 단백질 양상은 다른 주에 비해 독특하였다. Aconamoeba app. 분리주의 동정 및 특성 파악에 Mt DNA RFLP 분석이 매우 유용할을 확인하였다. Aconamoebacasteunil의 우리말 학명을 카스텔라니가시아메바로 제안한다.
