Asymptomatic infection of mouse hepatitis virus in the rat	1979		.txt	text/plain	954	70	59	After intranasal inoculation of suckling rats mouse hepatitis virus multiplied mostly in the nasal epithelium; though there were no symptoms, antibodies were produced. Bar represents 0.1 mm Two-, 4-, 6-and t0-week-old rats were also inoculated i.n. with t05 PFU of MHV-S and infectious viruses were assayed in the lung, brain, salivary glands and liver. So far only mice have been considered to be natural hosts of MHV and rat; has been excluded because highly virulent MHV inoculated by various routes did not cause any sy~lptomatic infection like that produced in the mouse (7, 13) . B~tATT and his eoworkers showed that SDAV multiplied in mice producing some histopathological changes in the respiratory system after i.n. inoculation (3) and we demonstrated in the w e s e n t paper that 3{HV infected rats of any ages.
