 AB    The defective murine AIDS (MAIDS) virus has unique sequences in its
       p15gag and p12gag regions. To clarify whether these sequences are
       responsible for the development of MAIDS, we constructed recombinant
       viruses by replacing various regions of the gag gene of the
       nonpathogenic replication-competent LP-BM5 ecotropic virus with those of
       the MAIDS virus. Recombinants containing both unique sequences of the
       MAIDS virus were replication defective and induced MAIDS. However, a
       recombinant containing either the p15gag or p12gag region of the MAIDS
       virus was also replication defective but nonpathogenic in mice. A
       recombinant virus containing only the p30gag region of the MAIDS virus
       was replication competent and nonpathogenic. These results indicate that
       the p15gag and p12gag regions of the MAIDS virus do not function like
       those of replication-competent viruses and that both of the unique
       sequences in the p15gag and p12gag regions are required to develop
       MAIDS.
