Disinfectants used: Disinfectant A (Potassium peroxymonosulfate,1%), Disinfectant B (peracetic acid and hydrogen peroxide, 1%), Disinfectant C (17.2% isopropanol), Disinfectant D (quaternary ammonium compounds, 0.5%), and Disinfectant E (quaternary ammonium compounds & glutaraldehyde, formaldehyde, 1%).
Different zones of different superscript letters (a,b,c & ab) of the same column are significantly different at P ≤ 0.05.
