Author Abstract

Background: In the UK, diseases caused by gastrointestinal nematodes (GINs) are the most expensive endemic diseases, being a major cause of morbidity, mortality and lost production in sheep flocks. Control is complicated by the increasing prevalence of anthelmintic resistance in the GIN population and changes in epidemiology, partially driven by climate change. Therefore, there is great emphasis among sheep farmers and veterinarians to find methods to successfully control GINs and prevent associated diseases.

Aim of the article: This article outlines the different strategies that can be implemented on farm to try and sustainably control parasitic gastrointestinal nematodes of sheep.

Immunosuppressant Therapy in Small Animal Medicine: What, When, and Why
Immunosuppressant drugs are categorized into steroid medications (e.g., prednisone, prednisolone, dexamethasone, budesonide), calcineurin inhibitors (e.g., cyclosporine), antiproliferative medications (e.g., azathioprine, mycophenolate, leflunomide), and mechanistic target of rapamycin inhibitors (not currently used routinely in veterinary medicine). This article focuses on the first 3 categories.
Surgical Anatomy of the Gastrointestinal Tract in Cats.
The aim of the present review is to describe in detail the anatomy of the gastrointestinal tract in cats, highlighting the anatomical regions of significant importance in different surgical procedures.
Intrathecal mepivacaine after general anesthesia is an effective method of equine euthanasia when compared to intravenous pentobarbital.
Previous publications have shown that the risk of scavenger intoxication through consumption of the carcass is low with an intrathecal lidocaine method. In horses euthanized with intravenous pentobarbital, sodium pentobarbital residues were found in compost pile samples up to 367 days after euthanasia with no decrease in concentration, despite complete degradation of soft tissues.
Quality assessment and characterization of unregulated antiviral drugs for feline infectious peritonitis: implications for treatment, safety, and efficacy.
Some of the GS-441524 vials were 10% to 25% more concentrated than advertised, but most of the GS-441524 samples tested were similar in purity and composition, both between batches and between brands. We also tested 5 vials of GC376 and found that 1 of the 5 vials contained GS-441524 rather than GC376 and the other 4 vials contained molnupiravir. GC376 is used in cats that are unresponsive to GS-441524, and use of the wrong antiviral can cause serious side effects. We provide suggested methods for distinguishing one drug from the other in new batches.
A review of prevention and management of castration complications
Despite castration being one of the most frequently performed elective equine surgical procedures, complication rates are high and range from severe life-threatening conditions to mild complications that are of no consequence to the horse. This article will briefly review strategies to prevent complications and surgical castration techniques before reviewing, in-depth, the following complications: excessive scrotal swelling and seroma formation, scrotal infection, septic funiculitis, septic peritonitis, haemorrhage, evisceration, omental prolapse, pyrexia, tetanus, penile trauma, hydrocele, signs of colic, and continued stallion-like behaviour.
