(ed. 5) iii. 352/2 Johnson..has isolated and identified the virus of feline panleukopenia (or feline enteritis) as a parvovirus. 1974J. A. Rose in Fraenkel-Conrat & Wagner Comprehensive Virol. III. i. 50 The biological significance of most of the parvoviruses is still obscure. Only the feline and related viruses are known to cause disease naturally, but the pathogenicity of rodent viruses under experimental conditions indicates that other disease potentials may exist... Because of their latency and hardiness, parvoviruses must always be considered as potential contaminants of cells, other virus stocks, and certain vaccines. 1976Fenner & White Med. Virol. (ed. 2) xxii. 424 There is current controversy about whether two important human pathogens, hepatitis A virus and the Norwalk agent of gastroenteritis, are parvoviruses or picornaviruses, but the former seems more likely.
