TL;DR: Disease-specific recommendations include incentives to undertake research aimed at the development of new diagnostic tests, veterinary-specific antimicrobial products and vaccines, as well as initiatives to promote best practices in veterinary diagnostic laboratories and prudent antimicrobial usage.

TL;DR: The main parasitic zoonoses in Europe related to dogs and cats are described, with particular emphasis on their current epidemiology, with an emphasis on parasite life cycle, transmission, pathogenicity, prevention and identification of knowledge gaps.

TL;DR: In small dogs, the risk of developing mammary tumours was three times higher than in large dogs, however, small dogs were less likely to be affected by many other tumour types (e.g. tumours of the skeletal system).

TL;DR: The present review provides a basis for comparison (even retrospectively) of lesions evaluated using different lung scoring systems, and a formula of equivalence between lung scoring methods was developed in order to compare the results obtained with these methods.

TL;DR: Findings confirm the participation of SenV-A in the multiple lesions observed in these piglets, and several theories are proposed.

TL;DR: Overall, bacterial infection was the most frequently diagnosed cause of death in captive birds, most commonly in Psittaciformes, followed by Passeriformes and Galliformes.

TL;DR: Tail docking of neonatal pigs is widely used as a measure to reduce the incidence of tail biting, a complex management problem in the pig industry, but concerns exist over the long-term consequences of tail docking for possible tail stump pain sensitivity due to the development of traumatic neuromas in injured peripheral nerves.

TL;DR: The present study analyses the influence of sex, neutering status, breed, time and age on the development of the most common tumour types and on their locations, using a multiple logistic regression model.

TL;DR: Results from this study suggest that IMinj challenge methods are not only suitable to induce streptococcosis in tilapia, but they may be the preferred method to study the pathogenesis of the naturally-occurring disease in this species.

TL;DR: The histopathological classification of inflammatory and neoplastic lesions of the canine stomach is reviewed and an update on the application of molecular techniques within the field of canine gastric pathology is provided.

TL;DR: The present study shows that caninegliomas form a range of immunohistochemical patterns that are similar to those described for human gliomas and might constitute an animal model for further characterization of these tumours.

TL;DR: Although the clinical significance of dental and TMJ pathology in the walrus remains unknown, the occurrence and severity of these lesions may play an important role in the morbidity and mortality of this species.

TL;DR: It is concluded that nasal pythiosis occurs sporadically in horses in the semi-arid region of northeastern Brazil where cutaneous pythium insidiosum is prevalent.

TL;DR: Prioritization of companion animal transmissible diseases was performed by the Companion Animals multisectoriaL interprofessionaL Interdisciplinary Strategic Think tank On zoonoses (CALLISTO) project, finding there were not enough assessments for any of the 15 diseases investigated.

TL;DR: The mission of the CALLISTO project was to provide an overview of the current situation on the role of companion animals as a source of infectious diseases for people and food animals and to identify knowledge and technology gaps for the most important zoonoses.

TL;DR: The results demonstrate the occurrence of FIV infection in inflammatory cells in the myocardium of five cats with myocarditis and HCM.

TL;DR: The current list of viruses provides an objective basis for more in-depth analysis of the risk of companion animals as sources of viruses for human and food production animal health.

TL;DR: Skulls from 277 California bobcats were examined macroscopically and by radiography and the most prevalent dental lesions found in the California bobcat were attrition/abrasion, periodontitis, and tooth fractures.

TL;DR: Severe foot lesions in dairy goats associated with digital dermatitis treponemes were characterized macroscopically, radiographically and histologically and the spirochaetal microorganisms located extracellularly in the superficial horn were identified.

TL;DR: Although the clinical significance of dental and TMJ pathology in the polar bear remains elusive, the occurrence and severity of these lesions may play an important role in the morbidity and mortality of this species.

TL;DR: It is concluded that INP inoculation and standardized systems of direct contact exposure provide effective alternatives to conventional (needle) inoculation systems for studies in which it is desirable to simulate the natural biology of FMDV infection.

TL;DR: This report represents the first documentation of disseminated HS in this species and supports a diagnosis on post-mortem examination of a 1.5-year-old African hedgehog presented in poor physical condition and with diarrhoea.

TL;DR: Pax8 was as sensitive as TTF-1 and slightly less sensitive than thyroglobulin for identification of follicular tumours, but had low sensitivity for C-cell tumours.

TL;DR: In this paper, a new method and its associated questionnaire and scoring system were designed based on methods described by the World Organisation for Animal Health (OIE) for the prioritization of transmissible diseases in companion animals.

TL;DR: This report provides the best evidence to date of chlamydial infection causing pneumonia in a koala, and the first evidence that C. pecorum is capable of infecting the bronchiolar epithelium of the koala.

TL;DR: In both species COX-2 and VEGF expression was correlated with the progression of the disease, but not with the presence of lymphatic invasion, tumour grading or tumour classification in the cutaneous tumours.

TL;DR: Cutaneous and subcutaneous soft tissue tumours have been rarely described in detail in snakes and several malignant entities show strikingly similar histological patterns and therefore the term soft tissue sarcoma (STS) has become a standard histopathological diagnosis.

TL;DR: Investigation of the expression of PGP and BCRP in the components of hyperplastic and neoplastic canine mammary glands showed that both markers are potentially expressed by epithelial cells, myoepithelial cells in complex tumours and mesenchymal cells in mixed tumours, but expression of both proteins was significantly higher in malignant epithelium or the epithelia of benign tumours.

TL;DR: In unaffected Friesian horses, the thickness of the tunica media, as well as the percentage area comprised of collagen type I, were significantly higher compared with the warmblood horses, supporting the hypothesis of a primary collagen disorder in the Friesia horse breed.

TL;DR: Pyogranulomatous rhinitis associated with an algal infection was diagnosed in a 25- year-old gelding and a 23-year-old mare had necrotizing sinusitis with intralesional algae and pigmented fungi.
