we have studied the replication of ecotropic murine leukemia viruses ( mulv ) in the spleens and thymuses of mice infected with the lymphocytic leukemia-inducing virus moloney mulv ( m-mulv ) , with the erythroleukemia-inducing virus friend mulv ( f-mulv ) , or with in vitro-constructed recombinants between these viruses in which the long terminal repeat ( ltr ) sequences have been exchanged .
