Sheep had viremias that were first detected on day 3 (+/- 1) after infection with several strains of bluetongue virus (BTV) representing United States serotypes 10, 11, 13, and 17. Diphasic peaks of infectivity were attained on days 6 and 10 (+/- 2).

A standard colonized population (000 line) of Culicoides variipennis (Coquillett) was used as the control for comparing the infection rate (IR) responses of different field populations of the vector to oral infection with several strains of bluetongu

A tracer method has been used to determine the relative amounts of phosphorus that a range of short-term crops and fallows derive from different parts of their root zone when growing on a phosphorus deficient latosol. The short-term crops made little

Abnormalities were commonly observed in spermatozoa, and bluetongue virus (BTV) was isolated from semen of 2 known BTV carrier bulls and 2 of 4 BTV seropositive field bulls. The spermatozoal abnormalities ranged from a small cavity between the acroso
