Numbers (log10 CFU/filter) of Escherichia coli O157:H7 (A and B) and Staphylococcus aureus (C and D) surviving on the surfaces of glass fiber filters as adhered cells (filled circle), biofilms formed at 28 °C for 3 days in TSB (type I) (filled inverted triangle), biofilms formed at 28 °C for 1 days on TSA (type II) (open circle), or biofilms formed at 28 °C for 3 days on TSA under 100% RH (type III) (open triangle) and stored at 43% (A and C) or 68% (B and D) RH for 7 days. Detection limit (dotted line) is 1.30 log CFU/filter
