Biofilm formation by <em>P. aerugin</em>osa has an important role in the bacterial pathogenesis as well as persistence in the environment. The antibacterial and antibiofilm activities of AgNPs and NaOCL were evaluated against <em>P. aerugin</em>osa isolated from chicken farms. MIC and MBC of AgNPs against planktonic cells of <em>P. aeruginosa </em>were 15 and 20µg/ml, respectively. While those of NaOCL were 2200 and 2600 µg/ml, respectively. The highest inhibition percentages of biofilm formation (97.9%) was observed when <em>P. aeruginosa</em> treated with AgNPs (25µg/ml). While, 87.5% biofilm removal percentage was achieved after treating the established biofilm with 25 µg/ml AgNPs for 2.5 h. Moreover, NaOCL (2800 µg/ml) was able to cause 96.6% inhibition of biofilm formation and 90.3% biofilm removal after 1.5 h contact. The current study revealed that AgNPs and NaOCL were able to promote a significant reduction and removal of the mature biofilms formed by <em>P. aeruginosa</em> and the antibiofilm efficiency increased with the increase of its contact times with the biofilms.</p>}, number={4}, journal={Journal of Advanced Veterinary Research}, author={Ismail, Abd El-Moez A. and Kotb, Saber A.H. and Mohamed, Israa M.A. and Abdel-Mohsein, Hosnia Swafy}, year={2019}, month={Oct.}, pages={178-186} }
