Abstract

Horizontal transmission of La Crosse (LAC) arbovirus in colonized was first observed in mating cages. LAC antigen was visualized by fluorescent antibody technique in multiple organs of 5 (2.5%) of 198 females dissected after contact in mating cages with males, with a transovarial infection rate of 31%. Venereal transmission of LAC virus was demonstrated by limited contact induced mating. Antigen was detected in bursal contents of 35 (53%) of 66 females dissected within 24 h after induced mating by males previously infected by intrathoracic inoculation. Antigen was observed in ovaries, heart, gut, salivary glands, or other organs in 13 (3.4%) of 379 females dissected 1 to 14 days post-mating. LAC virus was isolated from infected males, from contents of the bursa copulatrix of females following mating, and from dissection remnants of 6 of the 13 females in which disseminated antigen had been observed. Venereally infected females were shown to be capable of transmission of LAC virus by bite to mice and to eggs.
