Dermatophilosis
Rain scald (also known as dermatophilosis, tufailosis, rain rot or streptothricosis) is a Dermatology, dermatological disease affecting cattle and horses. Once in the skin, the bacterium ''Dermatophilus congolensis'' causes inflammation of the skin as well as the appearance of scabs and lesions. Symptoms and signs There are two different manifestations of rain scald: the winter form, which is more severe due to the longer coat of the horse, and the summer form, which is less severe. Horses are usually affected on the back, head, and neck where insects commonly bite, and the legs, which are commonly infected if the horse is kept in moist footing. Initially, the horse will display a matted coat and bumps which will progress to crusty scabs and lesions. The animal may also be Itch, pruritic and display signs of discomfort. Diagnosis Diagnosis is most commonly done with the identification of bacteria in the lesions by microscopic evaluation. A positive diagnosis of rain scald can be co ...

Dermatophilus Congolensis
''Dermatophilus congolensis'' is a Gram-positive bacterium and the cause of a disease called dermatophilosis (sometimes called mud fever) in animals and humans, a dermatologic condition that manifests as the formation of crusty scabs containing the microorganism. It has been erroneously called mycotic dermatitis. Rainscald is another condition often seen in animals, which is also caused by ''D. congolensis''. Morphology ''D. congolensis'' is facultative anaerobic actinomycete. It has two morphologic forms - filamentous hyphae and motile zoospores. The hyphae are characterized by branching filaments (1-5 µm in diameter) that ultimately fragment by both transverse and longitudinal separation into packets of coccoid cells. The coccoid cells mature into flagellated ovoid zoospores (0.6-1.0 µm in diameter). With the microscope, one can observe the characteristic "tramcar line"-like ''D. congolensis'' colonies together with Gram-positive thin filaments and coccoid forms. ...
