Three isolates of bovine astrovirus, one from the United Kingdom and two from the United States, possessed common antigens by immunofluorescence and strain-specific antigens by neutralization and were designated as two, and probably three, distinct serotypes. The isolate US2, despite being a different serotype, possessed the same restrictive cell tropism and cytopathology as previously reported for isolate US1, of the M cells of the dome epithelium of the Peyer's patches. Serotyping of 16 field isolates indicated the presence of more undefined serotypes.
三株牛星状病毒，一株来自英国，两株来自美国，通过免疫荧光法显示具有共同抗原，通过中和试验显示具有菌株特异性抗原，被指定为两种，可能是三种不同的血清型。尽管分离株US2属于不同血清型，但它具有与先前报道的分离株US1相同的限制性细胞嗜性和细胞病理学特征，即派伊尔结圆顶上皮的M细胞。对16株现场分离株进行血清分型表明存在更多未明确的血清型。
