Characterization of two serotypes of adenovirus isolated from sheep in the central United States.

: Two serotypes of adenovirus were isolated from lambs assembled at a ram testing station. The isolates were identified as adenoviruses on the basis of their morphologic and physicochemical characteristics. One isolate (RTS-42) was neutralized by antiserum to ovine adenovirus serotype 5, whereas the other strain (RTS-151) was not neutralized by the antisera to ovine adenovirus serotypes 1 through 5 or bovine adenovirus 1 through 8.
