Study of in vitro inhibitory activity of Pseudomonas aeruginosa against methicillin-resistant Staphylococcus epidermidis and Enterococcus faecalis

Objective To evaluate the in vitro inhibitory activity of antibacterial material of Pseudomonas aeruginosa against methicillin-resistant Staphylococcus epidermidis(MRSE),and Enterococcus faecalis. Methods The in vitro inhibitory activity of antibacterial material of Pseudomonas aeruginosa against 10 MRSE,and 12 Enterococcus faecalis was performed by using the cross streak assay. Results The in vitro inhibitory activity of antibacterial material of Pseudomonas aeruginosa against MRSE,and E.faecalis was good.The inhibition rates of No.3,4,5,6 and 8,9 of P.aeruginosas against MRSE were up to 100%,and No.1,3,4,and 6 of P.aeruginosas against E faecalis up to 100%,too. Conclusion The antibacterial material of Pseudomonas aeruginosa against 10 MRSE,and 11 E faecalis had strong antibacterial activity,which brings the potential to open a new train of thoughts for the antibiotics research of MRSE,and Enterococcus infections.
