Moraxella bovis, the causative agent of infectious bovine keratoconjunctivitis, exhibits several virulence factors, including pili, haemolysin, leukotoxin, and proteases. The pili are filamentous appendages which mediate bacterial adherence. Prior studies have shown that Q-piliated M. bovis Epp63 are more infectious and more pathogenic than I-piliated and non-piliated isogenic variants, suggest...

the aim of this study was to evaluate the efficacy of a hyaluronic acid containing eye drop in ameliorating ocular surface pathology and discomfort in canine keratoconjunctivitis sicca (kcs). twenty five dogs with kcs treated with a topical carbomer (ca)-based tear replacement gel were moved to treatment with a hyaluronic acid (ha)-containing tear replacement eye drop. dogs were subject to a fu...

Subepithelial infiltrates secondary to adenoviral keratoconjunctivitis may persist for years and cause blurred vision, halos, glare, and photophobia. These infiltrates arise from immune reaction against the virus, and few studies have reported topical cyclosporine A to be effective in the treatment of subepithelial infiltrates. Herein, we describe a patient with adenoviral keratoconjunctivitis-...

Epidemic viral conjunctivitis is a highly contagious disease that is encountered year-round. The causative agents are mainly adenoviruses and enteroviruses. It occurs most commonly upon infection with subgroup D adenoviruses of types 8, 19, or 37. For common corneal involvement of human adenovirus type 8 epidemic keratoconjunctivitis, full-layer epithelial detachment is rarely seen. Herein, we ...

Bovine herpes viruses belong to the family Herpesviridae. Bovine herpes virus 1 (BHV-1) is of world wide distribution and causes a wide range of diseases in cattle namely respiratory disease, keratoconjunctivitis and reproductive diseases including infectious pustular vulvovaginitis (IPV) in cows, infectious pustular balonoposthitis (IPB) in bulls and abortions. DNA studies of BHV-1 have reveal...

conjunctivitis This condition is manifested as congestion or oedema (chemosis) of the conjunctiva. It may be accompanied by an ocular discharge. Secondary conjunctivitis may occur with other ocular conditions, such as uveitis and glaucoma. In cats, conjunctivitis is frequently caused by an infectious agent, and multiple agents may be involved. Resident ocular bacterial flora is present; therefo...
