Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

Journal of Fish Diseases, EarlyView.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

Differences in Feeding Management of Pet Rabbits by Owners and Hobby Breeders and Their Impact on Animals' Health: A Survey

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Over the last decades, the population of pet rabbits in Europe has increased significantly, but to date studies into feeding management of these species have been mainly conducted in production animals. This study aimed to evaluate the feeding practices of both pet rabbit owners and hobby breeders in Germany and how these may affect animal ...

Infection with the Neorickettsial Organism Stellantchasmus falcatus Agent in an Arctic Fox (Vulpes lagopus)

Veterinary Clinical Pathology, EarlyView.
ABSTRACT A 1‐year‐old female‐intact arctic fox (Vulpes lagopus) presented for diarrhea, lethargy, severe thrombocytopenia, and hyperbilirubinemia. Blood film evaluation revealed intracytoplasmic coccoid bacteria within moderate numbers of leukocytes consistent with infection by a rickettsial organism.
