Evaluation of the celite secondary concentration procedure and an alternate elution buffer for the recovery of enteric adenoviruses 40 and 41

► Celite and organic flocculation method recovered similar levels of adenovirus. ► Sodium phosphate produced significant PCR inhibition compared to that of PBS. ► Heat was inefficient compared to chemical extraction for aggregated adenovirus. ► Celite technique recovered 69% of adenovirus 40 and 65% of adenovirus 41.
