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.

Self-Reported Management of Incidentally Detected Heart Murmurs in Puppies: A Survey among Veterinarians.
Data from 452 respondents were analyzed. Though 88% of the respondents find detecting a heart murmur easy, only 9% find differentiating innocent murmurs from pathologic murmurs in puppies easy. Of the respondents, only 80% recommend immediate additional examination when detecting a loud heart murmur during the first veterinary health check at 6 weeks of age. Of the respondents, 31% were uncertain whether early surgical intervention could lead to improved outcomes.

Computed tomography findings of nasal cryptococcosis in Australia (2008-2020): 12 dogs and 9 cats.
Dogs were more likely to have a nasal mass, whereas cats were more likely to have a nasopharyngeal mass. Cribriform plate lysis was common in dogs, but not observed in cats. Sinonasal osteolysis was a common feature in both species. Mandibular lymph nodes were commonly enlarged in dogs, whereas in cats, the retropharyngeal lymph nodes were more likely enlarged.

Endoparasites of rabbits and hares.
Accurate gross and microscopic identification of endoparasites in rabbits and hares is an important element of the diagnostic work of veterinary anatomic pathologists. Given the zoonotic nature of rabbit and hare endoparasites, such as C. hepatica, E. cuniculi, and others, veterinary pathologists are ideally poised to make valuable contributions to the understanding of the disease ecology of these pathogens in the context of a One Health research program.

Common Neurologic Diseases in Geriatric Dogs.
Neurological diseases are common in geriatric dogs, and although they can present with dramatic clinical signs, in a high percentage of cases, adequate management and a good quality of life for the patient can be achieved with symptomatic treatment.
