Bovine leukemia virus (BLV) was transmitted by rectal inoculation of BLV-infective whole blood into cattle and sheep. Two cows and 2 sheep each were given 500 ml and 50 ml of blood, respectively, by rectal infusion. Two sheep which served as positive controls each were given 1 ml of the same blood, IV. All animals became seropositive to BLV by postinoculation week 5. Although relatively large volumes of blood were used for rectal inoculation, a base line for infectivity was established for the rectal route.
通过将感染牛白血病病毒（BLV）的全血经直肠接种到牛和羊体内来传播BLV。分别给两头牛和两只羊经直肠输注500毫升和50毫升血液。作为阳性对照的两只羊分别静脉注射1毫升相同的血液。接种后第5周时，所有动物的BLV血清学检测均呈阳性。尽管经直肠接种使用了相对大量的血液，但还是确定了经直肠途径的感染性基线。
