The objective of this study was to determine whether semen from male
domestic cats infected with feline immunodeficiency virus (FIV) can
transmit virus to females. Twelve inseminations were performed by an
intrauterine laparoscopic technique with fresh or cryopreserved
electroejaculates from asymptomatic males chronically infected with the
NCSU1 strain of FIV. Of six inseminations performed with fresh semen, three
resulted in infection of queens, as indicated by seroconversion, expression
of FIV gag provirus in peripheral blood leukocytes, and reduced peripheral
CD4+/CD8+ T-lymphocyte ratios. None of the six inseminates with thawed
cryopreserved semen resulted in infection. Two infected queens and one
uninfected queen became pregnant. Virus was not evident in the seven
offspring. We conclude that FIV can be transmitted horizontally by
artificial insemination with fresh semen.
