Enterovirus Recovery with Vegetable Floc

¹ Food Research Laboratories, Microbiology Division, Health and Welfare Canada, Ottawa, K1A OL2, Canada

ABSTRACT

A lettuce floc was prepared and used for recovering enterovirus from an aqueous suspension. The method is simple, and the adsorption of coxsackievirus B5, echovirus 7, and poliovirus 1 is quantitative. The virus-floc complex may be removed from aqueous suspension by low-speed centrifugation and dissolved at an alkaline pH in a small volume of water; virus is then available for assay on cultured cells. Flocs from some other green vegetables also possess the property of virus adsorption
