Bovine papillomavirus gene expression and inflammatory pathway activation vary between equine sarcoid tumour subtypes.

Equine sarcoids are common non-metastasising skin tumours in horses, associated with bovine papillomavirus (BPV) infection. Six subtypes are recognised (occult, verrucose, nodular, fibroblastic, mixed and malevolent lesions), with variable clinical behaviour. The pathophysiology underlying varying tumour phenotype is poorly understood, and previous data on associations with viral load have been conflicting.

Ex vivo comparison of barbed sutures for pelvic flexure enterotomy in horses.

Objective: To evaluate two different barbed sutures for closure of pelvic flexure enterotomies and compare results achieved with two previously described closure techniques.

Study Design: Ex vivo.

Sample Population: Twenty-four fresh cadaver adult equine large colons.

Environmental surveillance identifies multiple introductions of MRSA CC398 in an Equine Veterinary Hospital in the UK, 2011-2016.

Bacterial environmental and surgical site infection (SSI) surveillance was implemented from 2011-2016 in a UK Equine Referral Veterinary Hospital and identified 81 methicillin-resistant Staphylococcus aureus (MRSA) isolates. A cluster of MRSA SSIs occurred in early 2016 with the isolates confirmed as ST398 by multilocus sequence typing (MLST), which prompted retrospective analysis of all MRSA isolates obtained from the environment (n = 62), SSIs (n = 13) and hand plates (n = 6) in the past five years. Sixty five of these isolates were typed to CC398 and a selection of these (n = 38) were further characterised for resistance and virulence genes, SCCmec and spa typing.

Diagnosis and treatment of dynamic collapse of the cricotracheal ligament in thoroughbred racehorses.

Objective: To describe (1) diagnosis of dynamic collapse of the cricotracheal ligament in a group of horses and (2) treatment and outcome of affected horses.

Study Design: Retrospective case series.

Animals: Thoroughbred horses (n = 8).
