They say April showers bring May flowers, but that’s not the only thing they bring. Rain rot, dew poisoning and abscesses are some of the less enjoyable products of spring’s rainy days and muddy pastures. While some horses seem to simply be more prone to wet weather-related ailments than others, there are a number of things horsemen can do to minimize the severity of ailments such as rain rot, or avoid them all together.
Though often mistaken as a fungal disease, rain rot (or rain scald) is a common bacterial infection of the skin (also known as Dermatophilosis). Dermatophilus congolensis, the bacteria that causes the infection, lives dormant in the outer layer of the skin. When the skin is exposed to prolonged moisture (high humidity, rain, sweat), the bacteria infects the compromised skin, resulting in crusty, puss-filled scabs between the living and dead layer of skin.
