Researchers in Norway have identified new insights into a deadly dog disease that caused the sudden death of over 40 dogs in 2019, pinpointing the bacterium Providencia alcalifaciens as a significant factor.
In the fall of 2019, dog owners across Norway faced a health crisis when numerous dogs were suddenly afflicted by acute bloody diarrhea, leading to the tragic deaths of more than 40 dogs. Veterinarians were initially at a loss regarding the cause, which alarmed pet owners and sparked immediate concerns about canine health. The unpredictability and rapid severity of the disease prompted urgent investigations by veterinary professionals and researchers alike.
A recent study conducted by researchers at the Veterinary Institute and NMBU has unveiled crucial findings regarding the bacterium Providencia alcalifaciens, which was suspected of being the cause of the illness. Although this bacterium was initially identified as a potential culprit, the specific conditions that made it dangerous were unclear. Bjarne Bergsjø, a laboratory leader at the Veterinary Institute, mentioned that the bacterium was rarely detected outside of the fall season, hinting at potential environmental or seasonal factors influencing its virulence.
By analyzing the DNA sequences of 273 bacterial samples collected from across Norway and comparing them with international samples, the research team was able to categorize the strains into two genetic groups. They discovered that a specific genetic group, identified as group A, was overrepresented in the sick dogs. These findings not only aid in understanding the dynamics of this dangerous bacterium but also equip veterinarians with better tools to diagnose and manage future outbreaks effectively, thereby enhancing dog health safety measures across Norway.
