Abstract
Three isolates of Breda virus of calves were compared morphologically and antigenically. The isolates demonstrated similar morphology and shared common antigens, as determined by enzyme-linked immunosorbent assay and immunoelectron microscopy. On the basis of results of the hemagglutination-inhibition test, ELISA, and immunoelectron microscopy, the 3 isolates were further subdivided into 2 serotypes: serotype I (Breda virus 1) represented by the Iowa [USA] isolate 1; and serotype 2 (Breda virus 2), by the Ohio [USA] isolate and the Iowa isolate 2. The 3 isolates caused diarrhea in gnotobiotic calves.
