 AB    OBJECTIVE: It was examined whether the unique sequences of defective
       murine AIDS virus in its gag p15 and p12 regions are responsible for the
       development of MAIDS. METHODS: Recombinant viruses by replacing various
       regions of the gag gene of nonpathogenic ecotropic virus, with those of
       the MAIDS virus were constructed and its pathogenicity was examined.
       RESULTS: Recombinant containing both unique sequences of the MAIDS virus
       were replication defective and pathogenic. However, a recombinant
       containing either the gag p15 or p12 region of the MAIDS virus was
       replication defective and nonpathogenic. DISCUSSION AND CONCLUSION: The
       gag p15 and p12 regions of the MAIDS virus do not function as those of
       replication-competent viruses, and that both of the unique sequences in
       the gag p15 and p12 regions are required to develop MAIDS.
