Microbiological and Chemical Exposure Assessment
Adenovirus and Parvovirus
Note the two virus types present in the photograph. The larger virus particles with prominent capsomeric detail on their surface are adenovirus particles. The small featureless particles seen mostly clumped between the adenovirus particles are parvovirus particles. Bar = 100 nanometers.
