Intermediate size papovavirus particles in pregnancy urine.
By electron microscopy of negatively stained urinary sediments, papovavirus particles of size intermediate between papillomavirus and polymavirus have been detected in the urine of a pregnant woman. The excretion of size variants of these viruses and the absence of detectable papillomas in any of the women who were found to excrete only papillomavirus represent new findings.
