title: Genotyping of mouse hepatitis virus strains by restriction endonuclease analysis of amplified nucleocapsid protein genes.
abstract: Restriction endonuclease analysis of amplified nucleocapsid protein genes from mouse hepatitis virus (MHV) was used to differentiate 12 strains isolated from mouse liver or transplantable tumors from five facilities, and the restriction patterns of the isolates were compared with those of five well-defined MHV strains, A59, JHM, 2, S and Nu-67. The patterns of 10 isolates from three facilities were the same as that of Nu-67. The remaining two isolates revealed different patterns from the five reference strains. This study showed that reverse transcription and the polymerase chain reaction assay based restriction analysis are feasible for the detection and genotyping of MHV, and the Nu-67 related strain was the most prevalent type found in the clinical samples.
