[Objective]

Green nails, a type of bacterial infection, are one of the causes of nail problems such as green discoloration. This green color is caused by Pseudomonas aeruginosa infection of nails. We examined the antimicrobial activity of OM-X extract against Pseudomonas aeruginosa.

[Methods]

Pseudomonas aeruginosa was propagated on a petri dish. A paper disk soaked with OM-X was placed in the center of the petri dish and cultured. If an antibacterial reaction occurs, an inhibition ring against bacteria is formed. We examined the antibacterial activity by measuring the size of the inhibition ring.

[Results]

OM-X formed a large inhibition ring against Pseudomonas aeruginosa. This means that it showed an antibacterial activity against Pseudomonas aeruginosa.
