Cytopathogenic agents have been isolated in a search for viruses in the feces of apparently healthy mice (an inbred strain DK1) by using mouse kidney tissue culture. This report is concerned with the identification of strain K87, one of our isolates, as an adenovirus. Strain K87 was cytopathogenic to mouse kidney tissue culture but not to monkey kidney tissue culture, FL, and HeLa cells. The K87 strain was not able to grow in bacterial media and was resistant to penicillin, streptomycin and tetracycline. 5‐Bromodeoxyuridine inhibited the occurrence of the cytopathogenic effect and virus replication in infected cells and the inhibitory effect was reversed by thymidine, suggesting that the virus contains DNA. Strain K87 was resistant to ethyl‐ether but did not have the property of cationic stabilization to thermal inactivation. Electronmicroscopic observations of thin‐sections of the K87‐infected cells showed virus particles in crystalline array in the nuclei. Each virus particle was an icosahedron of about 75 mμ in diameter composed of 252 capsomeres, and without an envelope. By the complement fixation test, K87 was related serologically to a human adenovirus. All the facts indicate that strain K87 belongs to the adenovirus group. The problem whether strain K87 may be a new mouse adenovirus with pathogenicity and antigenicity different from that of a mouse adenovirus previously reported by Hartley and Rowe is discussed.
