Abstract

Bluetongue virus (BTV) was biologically transmitted by the bites of colonized gnats to recipient sheep from a Hereford bull with latent infection. Four biological recoveries of BTV were mediated over 2 years by multiple feedings of the vector during a 4- to 72-hour interval. Initial stimulation by gnat bites at 0 hour permitted biological recovery of BTV by gnats that fed at later intervals. The 4th biological recovery of the virus from the bull clearly indicated a vector-mediated viral recovery mechanism in which initial vector bites at 0 hours stimulated a “showering” of BTV into the blood stream of the bull. The BTV carrier bull developed no overt signs of illness during these studies. The pertinent BTV assay and serologic results for the 4 ⅓ years of the bull's life are summarized in this report.
