Yeast Infection


Most people are familiar with the phrase “yeast infection.” However, many people don’t actually know what a yeast infection is. Yeast is a general term that refers to a kind of single-celled fungus that reproduces by a process called budding. Budding is a type of asexual or genderless reproduction in which a portion of the organism’s cell body becomes separated, pinching off to form a whole new yeast organism. Skin yeast infections are extremely common in domestic dogs. The species that cause most of these infections is Malassezia pachydermatis. This type of yeast is a normal inhabitant of a dog’s skin, in manageable numbers. It likes to live in the host dog’s fatty tissues and is especially fond of the ears. A yeast infection occurs when the yeast start to reproduce uncontrollably, over-populating the areas of skin where they normally live, but in much smaller numbers.
