Special Issue Information

Dear Colleagues,

Infectious diseases remain a significant challenge in veterinary medicine, particularly in the context of companion animals, where they significantly impact animal health, welfare, and the broader One Health landscape. The dynamic interactions between pathogens, hosts, and the environment—further amplified by global mobility, antimicrobial resistance, and climate change—call for focused, interdisciplinary research.

This Special Issue, titled "Infectious Disease in Companion Animals," aims to collect high-quality contributions that address infectious diseases affecting companion animals, including viral, bacterial, fungal, and parasitic agents. We welcome original research and review articles on various topics such as epidemiology, diagnosis, pathogenesis, molecular characterization, surveillance, prevention, and control.

Special attention will be given to studies investigating the zoonotic potential of pathogens in companion animals and how environmental or anthropogenic factors influence the emergence and spread of diseases. Innovative approaches involving advanced diagnostics, molecular tools, and integrative surveillance strategies are highly encouraged.

We look forward to receiving your contributions to help advance our understanding of infectious diseases in companion animal populations.

Dr. Olga Szalus̈-Jordanow

Raw meat-based diets (RMBDs) have become increasingly popular among pet owners, despite well-documented risks of contamination with pathogenic bacteria capable of causing severe illness in companion animals. This report describes a fatal case of botulism in a 3-year-old female Labrador Retriever weighing 37 kg that was fed exclusively RMBD. The dog presented with acute-onset flaccid paralysis of the limbs approximately 48 h after possible ingestion of decomposing raw meat discarded in household waste. Supportive therapy, including fluid administration, nutritional support and eventual mechanical ventilation was provided. However, the patient developed progressive respiratory failure and died. The presence of Clostridium botulinum type C neurotoxin was confirmed in the dog serum by neutralization test in mice. The case suggests RMBD as a potential source of botulism toxins, particularly when derived from improperly stored meat products. The findings underscore the importance of detailed dietary history in dogs presenting with acute flaccid paralysis and reinforce the need for heightened awareness regarding the microbiological risks associated with raw feeding practices.
