A. Examples of Useful Model Viruses:
1. Nonspecific model viruses representing a range of physico-chemical structures:
SV40 (Polyomavirus maccacae 1), human polio virus 1 (Sabin), animal parvovirus or some other small, nonenveloped viruses;
a parainfluenza virus or influenza virus, Sindbis virus or some other medium-to-large, enveloped, RNA viruses;
a herpes virus (e.g., HSV-1 or a pseudorabies virus), or some other medium-to-large, DNA viruses.
These viruses are examples only and their use is not mandatory.
2. For rodent cell substrates murine retroviruses are commonly used as specific model viruses.
