Abstract
The current study was conducted to determine the commensal bacterial and fungal species isolated from eyes of clinically healthy Equines, the epidemiological patterns of ophthalmic bacterial and fungal Infection in Equines, and investigate the antibiotic resistance genes in the bacterial species. The present study was conducted on a total number of 100 equine species aged between 4 months to 22 years old. Of all, 28 animals were regarded as diseased and 72 clinically healthy animals. Detailed data concerned with fully case history, clinical findings, and medical record for each animal were investigated. The following results were obtained:1.The recorded clinical signs in horses with ophthalmic infetion were conjunctival hyperemia, continuous lacrimation, belpharospasm, eye lid edema, mucopurulent ocular discharge , and corneal opacity without any systemic reaction.2. The bacterial and fungal organisms are commensal and become opportunistic in the presence of any risk factors.3. Concerning Staphylococcus and Pseudomonas species, they were isolated from eyes of healthy animals as a commensal organisms however, the isolation percentage of them increased in animals with ophthalmic infection. On the other hand, E.coli isolated only from animals with ophthalmic infection. 4.For antibiotic sensitivity test of Staphylococcus, Pseudomonas species and E.coli there were a varying degree of resistance showed for different antimicrobials. 5.For fungal organisms they were commensals and become opportunistic in the presence of risk factors, also, there were a significant association between bacterial and fungal organisms and some of the studied risk factors.
