Dear to whom this may concern,

I am about to inoculate a viral suspension (infectious bronchitis) into embryonated egg but I need to know the concentration of viral particle in the suspension. Since my lab has limited consumable and equipments, what is the easiest and most comfortable methods to do this? Note; the suspension is made by homogenizing affected tracheas tissue with PBS+Antibiotics.

Regards and your replies are highly appreciated!
