  • Title: Enterotropic mouse hepatitis virus infection in nude mice.
    Author: Barthold SW, Smith AL, Povar ML.
    Journal: Lab Anim Sci; 1985 Dec; 35(6):613-8. PubMed ID: 3005764.
    Abstract:
    The cause of emaciation and diarrhea in athymic nude mice was found to be hyperplastic typhlocolitis resulting from infection with enterotropic mouse hepatitis virus (MHV). The disease was reproduced in experimentally-inoculated nude mice using intestinal homogenates from affected mice and cell culture-derived virus. Material derived from an experimental mouse was passed into neonatal Swiss mice and caused acute typhlocolitis. Virus failed to grow in NCTC-1469 cells and 17Cl-1 cells, which are normally permissive for MHV, but grew to low titer in a mouse rectal carcinoma cell line, CMT 93. These results show that an enterotropic strain of MHV can cause chronic enteric disease in athymic nude mice. The pattern of infection differs markedly from the more common MHV wasting syndrome in nude mice caused by non-enteric strains of MHV.
