Circumflex left aortic arch: a new vascular ring anomaly in dogs.

Objective: To describe the circumflex left aortic arch as a new form of canine congenital vascular ring anomaly leading to esophageal constriction.

Animals: 3 large-breed dogs of variable age: a 9-month-old entire male German Shepherd Dog-Rottweiler cross, a 17-week-old entire male German Shepherd Dog, and a 9-year-old neutered female Labrador Retriever, seen between April 2022 and May 2023.

Clinical Presentation: Dogs presented for chronic postprandial regurgitation and poor growth.

Staphylococcus caeli sp. nov., isolated from air sampling in an industrial rabbit holding.

Strain 82, a Gram-stain-positive, coagulase-negative staphylococcus was isolated from an air sample obtained from an industrial rabbit holding in Italy. It is phylogenetically closely related to the coagulase-negative species Staphylococcus saprophyticus, Staphylococcus xylosus and Staphylococcus edaphicus. However, it could be distinguished from these species by sequence differences between the 16S rRNA, hsp60, rpoB, dnaJ and gap genes.

Genome analysis of methicillin resistance in Macrococcus caseolyticus from dairy cattle in England and Wales.

Species of the genus Macrococcus are widespread commensals of animals but are becoming increasingly recognised as veterinary pathogens. They can encode methicillin resistance and are implicated in its spread to the closely-related, but more pathogenic, staphylococci. In this study we have identified 33 isolates of methicillin-resistant Macrococcus caseolyticus from bovine bulk tank milk from England and Wales.

A retrospective analysis of urethral rupture in 63 cats.

The aim of this study was to investigate the short- and long-term morbidity and mortality associated with urethral rupture in cats. Medical records were reviewed from four veterinary hospitals. Diagnosis was made from retrograde urethrography or direct visualisation during surgery.
