title: Rapid semiquantitative method for screening large numbers of virus samples by negative staining electron microscopy.
abstract: A rapid, semiquantitative method for screening large numbers of virus samples by negative staining electron microscopy is presented. Results obtained by this method are compared with results obtained by the pseudoreplica method and a measureddrop method. A figure is presented which represents the limit of detectability for virus by negative staining.
