Numerous small unenveloped rod-like particles and a few longer forms were seen in purified, concentrated preparations of infective virus, and associated with virus-infected mycoplasmal cells in culture. Observations on these virus particles are discussed in relation to their structure. %U https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-16-2-215
