Quizplus · Accepted Answer

The presence of Dane particles, filamentous, and spherical virion particles indicates infection with Hepatitis B virus. Dane particles are the complete infectious particles of Hepatitis B virus that contain the genome and capsid, while filamentous and spherical virion particles are produced during replication and release of the virus. Human herpesvirus 1, EBV, VZV are all enveloped viruses and do not produce Dane particles, while hepatitis D virus is a defective virus that requires the presence of hepatitis B virus for replication.
