Effects of the Dibenzofuran, Usnic Acid, on Inhibition of Ocular Biofilm Formation Due to Coagulase-Negative Staphylococci

Abstract: Background:Coagulase-negative staphylococci (CoNS) are gram-positive, aerobic, commensal bacteria found on the skin and mucous membranes, including the conjunctiva. Usnic acid (UA) is a dibenzofuran derivative isolated from lichens. This study aimed to investigate the effects of usnic acid on inhibition of ocular biofilm formation due to CoNS. Material/Methods:Nine Staphylococcus epidermidis isolates, 5 Staphylococcus hominis isolates, 2 Staphylococcus saprophyticus isolates, and 1 Staphylococcus capitis and S… Show more

“…Staphylococcal biofilms represent a critical issue in device-related eye infections and in ocular diseases like keratitis [9,11]. In fact, most S. aureus and S. epidermidis ocular isolates have been shown to be biofilm-proficient on abiotic surfaces, including ocular prostheses and contact lenses, and on ex vivo human corneas [29][30][31][32][33][34][35][36].…”
