ADSORPTION OF INFLUENZA A VIRUS BY AEROBACTER AEROGENES SPHEROPLASTS

ABSTRACT

BROWN, RONALD J. (University of Kansas, Lawrence), ALBERT A. BENEDICT, AND NANCY ARMSTRONG. Adsorption of influenza A virus by Aerobacter aerogenes spheroplasts. J. Bacteriol. 83:1124–1130. 1962.—Aerobacter aerogenes spheroplasts adsorbed virus at a greater rate than whole A. aerogenes cells or cell-wall preparations. The largest fragments of sonic-disrupted spheroplasts were responsible for adsorption. Adsorption was characterized by rapid disappearance of viral hemagglutinin in about 8 min, elution of hemagglutinin, and followed again by complete adsorption of hemagglutinin. Viral activity was not recovered from spheroplasts after the final adsorption phase. Spheroplasts treated with heat, dilute periodate, or formaldehyde did not adsorb virus, and treatment of spheroplasts with receptor-destroying enzyme resulted in delayed adsorption.
