A new study published in Veterinary Ophthalmology has examined antimicrobial resistance within veterinary ophthalmology.
The authors highlighted that antimicrobial resistance is a “growing challenge” in veterinary practice – with some bacterial species having ‘zoonotic potential’ (the ability to transfer between animals and humans).
“Antimicrobial resistance has evolved from an abstract public health concern into a daily clinical challenge in veterinary ophthalmology,” the researchers reflected.
By examining studies from North America, Europe, Asia, South America, and Australia, the researchers highlight that Staphylococcus pseudintermedius, beta-hemolytic streptococci, and Pseudomonas aeruginosa are among the most frequently isolated pathogens among companion animals.
The researchers noted that there have been documented cases of Staphylococcus pseudintermedius – the most commonly isolated bacterial strain among dogs – in humans.
They highlighted that veterinary clinics and veterinary staff may form part of the transmission network.
“Resistant organisms can persist on hands, examination tables, tonometer tips, diagnostic lenses, drop bottles, and other ophthalmic instruments if disinfection protocols are inadequate,” the authors noted.
“Close contact during restraint, topical drug administration, and postoperative care increases opportunities for bidirectional exchange between animals and humans,” the researchers shared.
The authors present a series of principles underpinning antibiotic stewardship in veterinary ophthalmology, including avoiding routine broad-spectrum prophylaxis, reserving systemic treatment for rare, justified circumstances and embedding infection control procedures within workflows.
“In ophthalmology, where intensive topical therapy, fast disease dynamics, and close human-animal contact coexist, even small steps can have a significant clinical and public health impact,” the researchers highlighted.
