Yudhi Nugraha

Hi Im

I think you can isolate by inoculation your sample into embryonated eggs or with tissue culture systems. you can check this link article.

Hi Im,

as Yudhi mentions you would need to culture the virus...

Isolation in embryonated eggs is (in my experience) the best approach for avian influenza viruses.
