Article Synopsis
  • The European hedgehog is declining in population, prompting conservation efforts, and this study focused on understanding the causes of death in hedgehogs admitted to a French rehabilitation center.
  • Out of 159 dead hedgehogs analyzed, 92% had identifiable causes of death, with impaired condition (30%), bacterial infections (26%), and trauma (20%) being the most common.
  • The study also found significant exposure to toxicants, such as anticoagulant rodenticides in 42% of hedgehogs, alongside a low prevalence of blood pathogens, emphasizing the need for further investigations into the health and ecological factors affecting hedgehog populations.

The last few years have seen a surge of interest from field ecologists and evolutionary biologists to study neoplasia and cancer in wildlife. This contributes to the One Health Approach, which investigates health issues at the intersection of people, wild and domestic animals, together with their changing environments. Nonetheless, the emerging field of wildlife cancer is currently constrained by methodological limitations in detecting cancer using non-invasive sampling.

Article Synopsis
  • This study investigates the occurrence of cutaneous apocrine gland tumors (CATs) in 16 captive African wild dogs (AWDs) from various countries between 1997 and 2022, focusing on those aged 5 to 14 years old.
  • The majority of affected AWDs were females, presenting as distinct, raised, hairless masses along the dorsal midline, primarily identified as malignant with potential for lymphatic spread.
  • The research indicates that older age and female sex increase the risk for CATs, suggesting the necessity for regular monitoring and surgical intervention, while also calling for further exploration of genetic, endocrine, and husbandry factors in their development.

The reduced species richness typical of oceanic islands provides an interesting environmental setup to examine in natura the epidemiological dynamics of infectious agents with potential implications for public health and/or conservation. On Amsterdam Island (Indian Ocean), recurrent die-offs of Indian yellow-nosed albatross (Thalassarche carteri) nestlings have been attributed to avian cholera, caused by the bacterium Pasteurella multocida. In order to help implementing efficient measures for the control of this disease, it is critical to better understand the local epidemiology of P.

The riparian European mink (Mustela lutreola), currently surviving in only three unconnected sites in Europe, is now listed as a critically endangered species in the IUCN Red List of Threatened Species. Habitat loss and degradation, anthropogenic mortality, interaction with the feral American mink (Neovison vison), and infectious diseases are among the main causes of its decline. In the Spanish Foral Community of Navarra, where the highest density of M.

Gastric ulcers are common in domestic horses and foals, affecting at least 90% of unmedicated racehorses in active training. Despite these high prevalences in domestic horses, literature about this condition in wild equids is almost nonexistent. The presence of gastric ulcers was evaluated at necropsy in six species of wild equids that died at the Réserve Africane de Sigean, a safari park in the south of France from 2010 to 2016.

To investigate cases of acute oxalate nephrosis without evidence of ethylene glycol exposure, archived data and tissues from cheetahs ( Acinonyx jubatus) from North America ( n = 297), southern Africa ( n = 257), and France ( n = 40) were evaluated. Renal and gastrointestinal tract lesions were characterized in a subset of animals with ( n = 100) and without ( n = 165) oxalate crystals at death. Crystals were confirmed as calcium oxalate by Raman spectroscopy in 45 of 47 cheetahs tested.

Squamous cell carcinoma (SCC) is well documented in snow leopards ( Uncia uncia ) and most common locations are oral, facial, or pedal. These two cases illustrate an unusual auricular presentation, which is more often reported in white domestic cats. The animals were aged and presented clinical signs of otitis such as head shaking and ear scratching.
