Current Evidence of Coryneform Bacteria on The Ocular Surface of Immunocompromised Cats
Journal Title: Journal of Applied Veterinary Sciences - Year 2021, Vol 6, Issue 3
Abstract
Monomicrobial and polymicrobial infections may occur on the cornea, conjunctiva and the eyelid of cats.<em>Corynebacterium</em> species are categorized as nonpathogenic bacteria that are regularly detected in the conjunctiva of healthy cats. It has been reported that <em>Corynebacterium</em> species have been shown to be potentially harmful in a variety of tissues including ocular tissues, skin, and mucous membranes. The purpose of the current study was to investigate the presence of <em>Corynebacterium</em> spp. on the ocular surface and its antimicrobial sensitivity and susceptibility pattern. We investigated <em>Corynebacterium</em> species on the ocular surface and reviewed various species of <em>Corynebacterium</em> in terms of their antimicrobial susceptibility and the underlying molecular resistance mechanisms. The risk for Corynebacterium-related ocular infections in cats with low immunity, such as poor nutrition, corneal epithelial damage due to trauma, corneal perforation, lagophthalmos, chronic incurable glaucoma, long-lasting corneal sequestrum, and long-term use of topical steroids have been identified. 64 cats (78 eyes) of different ages and both sexes with various ocular disorders were swabbed. <em>Corynebacterium </em>spp. represented 34.6 % (n=27) of the collected sample and found to be susceptible to common antibiotics. Therefore, the use of antimicrobials for the treatment of ocular infections caused by <em>Corynebacterium</em> species should be a rational and sensible strategy along with provision of immunostimulants.
