Agglutination of African primate and rodent erythrocytes by adenoviruses, reoviruses, and enteroviruses.

African nonhuman primate and rodent erythrocytes were tested for agglutination by adenoviruses, reoviruses, and enteroviruses. Squirrel erythrocytes were agglutinated by reovirus serotypes and adenovirus types 3, 11, 16, and 21. Adenoviruses also agglutinated brazza monkey erythrocytes to the same titers as those obtained with either rhesus or grey monkey cells. Prototype reovirus types 1 and 2 agglutinated grey monkey erythrocytes to much lower titers than either squirrel or human group O red cells. Among the enteroviruses tested, only echovirus types 7 and 12 agglutinated grey, red-tail, brazza, and rhesus monkey erythrocytes. The specificity of agglutination of squirrel, grey, and brazza monkey erythrocytes by reoviruses, echoviruses, and adenoviruses, respectively, was confirmed by hemagglutination-inhibition tests. The titers obtained were similar to those obtained with erythrocytes usually used in these tests. Erythrocytes of bush babies, potto unstriped grass mice, swamp rat, rusty-nosed rat, bush rat, harsh-furred mice, soft-furred rat, and giant rat were not agglutinated by adenoviruses, reoviruses, or enteroviruses.
