This sassy little rat snake recently arrived at MARS after being found by Lavender Moon Garden & Studio with several unusual raised lumps on its scales. While there are a number of possible causes for skin abnormalities in snakes, one concern is Snake Fungal Disease (SFD), an emerging disease that has been documented in multiple wild snake species throughout Michigan.
Because we already have another snake in our care undergoing testing for SFD, we made the decision to admit this patient and collect diagnostic swabs as well. The presence of skin lesions, crusting, swelling, or abnormal lumps can sometimes be associated with the disease, and testing helps us better understand what we're seeing, not just for the individual animal, but for snake populations as a whole.
Snake Fungal Disease is caused by the fungus Ophidiomyces ophidiicola and can affect many species of snakes. In severe cases, it may lead to significant skin damage, difficulty shedding, facial swelling, reduced ability to hunt, and even death. While not every snake with skin abnormalities has SFD, identifying and tracking cases is critical for understanding how the disease is impacting wild populations.
Wildlife rehabilitators occupy a unique position on the front lines of wildlife health monitoring. Every injured, sick, or abnormal animal that comes through our doors represents an opportunity to gather valuable information that may contribute to broader conservation efforts. Diseases don't respect county lines or property boundaries, and early detection often depends on observations made by people working directly with wildlife.
At MARS, we take that responsibility seriously. Whenever possible, we pursue diagnostic testing for diseases that may have implications beyond a single patient. The information gained from these cases can help researchers, wildlife agencies, veterinarians, and rehabilitators better understand emerging threats facing Michigan's native reptiles and amphibians.
We'll share updates on this snake's results when they become available. In the meantime, this little patient is hanging out with us while we wait for answers.
At MARS, we provide expert rehabilitation for cold-blooded animals, both wild and domestic. By working alongside a veterinarian who specializes in reptiles and amphibians, we’re able to ensure that every patient who comes through our doors receives the specialized, compassionate, and often life-saving care they deserve.
