What is Pythiosis?

Pythiosis, caused by Pythium, is a fungal-like infection affecting primarily dogs, but cats and other animals can also be infected. Pythiosis is found on multiple continents around the world and can be diagnosed anywhere in the U.S. Pythium likes warm temperatures and is most common in southern states. Pythiosis is not contagious to other animals or humans, but occurs when a dog or cat wades in, or ingests, water where Pythium lives. Pythiosis most commonly infects young animals (<5 years) which could be due to the fact that they are more likely to roam around and wade in water. If other animals are showing signs of illness, or if you have concerns, it is important to talk with your veterinarian. Early diagnosis can help with successful treatment. If you have concerns for yourself, or other people in the household, you should talk with your physician.
