The effect of D1 (chlorine-based), D3 (hydrogen peroxide/peracetic acid), D4 (isopropyl alcohol), D5 (glutaraldehyde solution), and D6 (peracetic acid-based) against spores of tested strains using the European and French standard NF EN 13704, in dirty conditions, with a standard initial bacterial charge of 1 × 106 CFU/mL. Untreated samples were used as a control for experimental conditions. The spore was suspended in sterile deionized water with the addition of (3% bovine serum albumin and 0.3% sheep erythrocytes); after 20 min of contact, the spore suspension was filtered and incubated. (C.S.) indicates reference strains used as control.
