Characterization of bacillus thuringiensis isolates form soil in wonju area: Yoo, Kwan Hee , Kim, Soo Young , Kang, Min Ho , Cho, Myung Hwan , Lee, Hyung Hoan; J. Microbiol. 1996;34(4):370-373.

Abstract PDF: There strains (KW-1, KW-14, KW-15) of Bacillus thuringiensis were isolated from soil in Wonju area and characterized. The three strains produced parasporal inclusion bodies (crystals) and spores in their cells. The KW-1 strain produces spherical crystals. The crystals of strain KW-14 are bipyramidal crystal. The KW-15 strain harbors irregular crystals. Only minor biochemical characteristics of the three isolates were different and distinctive, however general characteristics were similar to the known serotypes of B. thuringiensis. Three strains were resistant to penicilin G, oxacillin and cephalothin. This strains were highly toxic to Bombyx mori larvae, but not to the Culex pipiens larvae.

Production of a monoclonal antibody and ultrastructure of the sporozoite of cryptosporidium parvum: Choi, Young Sook , Lee, Sung Tae , Cho, Myung Hwan; J. Microbiol. 1996;34(4):379-383.

Abstract PDF: Cryptosporidium Parvum causes a life-threatening diarrhea in acquired immunodeficiency syndrome (AIDS) patients. The sporozoite stage of C. parvum has been known to be a target in treating cryptosporidiosis in AIDS patients as it is an extracellular stage. A sporozoite was ultrastructurally observed. It has a crescent shape with a rounded posterior end and a tapering body. The compact nucleus was located at the posterior end. A monoclonal antibody was produced, which recognized a 43 kDa of sporozoite antigens in a western blot analysis and showed the surface labeling in immunofluorescence.
