Canine pigmented viral plaques associated with application of potent topical glucocorticoids.

A six-year-old atopic boxer presented with pigmented viral plaques on the interdigital spaces and pinnae following treatment with potent topical glucocorticoids. The lesions regressed after treatment was discontinued, and recurred each time a topical glucocorticoid was resumed. A Chipapillomavirus was amplified from lesional tissue.

[Food hygiene and safety - What is your diagnosis?].

A healthy, 1,5 year old female wild boar (Sus scrofa) was shoot in a hunting district in Switzerland on June 22, 2023. The meat inspection revealed noticeable skin changes on all four distal extremities which were described histologically as multifocal epidermal hyperplasia and moderate orthokeratotic hyperkeratosis. The rest of the animal body, the organs and the lymph nodes were without any obvious lesions.

Equine Parvovirus-Hepatitis Screening in Horses and Donkeys with Histopathologic Liver Abnormalities.

There is strong evidence that equine parvovirus-hepatitis (EqPV-H) is associated with the onset of Theiler's disease, an acute hepatic necrosis, in horses. However, the impact of this virus on other hepatopathies remains unknown. The objective of this retrospective study was to evaluate the prevalence and quantify the viral loads of EqPV-H in formalin-fixed, paraffin-embedded equine and donkey livers with various histopathologic abnormalities.

Establishment of a Three-Dimensional In Vitro Model of Equine Papillomavirus Type 2 Infection.

There is growing evidence that equine papillomavirus type 2 (EcPV2) infection is etiologically associated with the development of genital squamous cell carcinoma (SCC) and precursor lesions in equids. However, the precise mechanisms underlying neoplastic progression remain unknown. To allow the study of EcPV2-induced carcinogenesis, we aimed to establish a primary equine cell culture model of EcPV2 infection.
