Animals including dogs and cats can also be affected by ringworm, and the disease can be transmitted between animals and humans, making it a zoonotic disease. Specific signs can be: red, scaly, itchy or raised patches; patches may be redder on outside edges or resemble a ring; patches that begin to ooze or develop a blister
Trichophyton mentagrophytes is one of three common fungi which cause ringworm in companion animals and frequently isolated from dogs, cats, rabbits, guinea pigs and other rodents. [2] [3] [4] It is the most common or one of the most common fungi that cause zoonotic skin disease (i.e., transmission of mycotic skin disease from species to species ...
Ringworm is a fungal infection that can be contagious to other dogs as well as humans. [10] It is one of the most frequent skin diseases. [ 11 ] A dog can become infected by direct contact with another infected dog, brushing up against a surface that an infected dog has touched, [ 12 ] as well as coming in contact with species of ringworm that ...
The disease in dogs can affect the lungs and skin, but more commonly the eye and central nervous system. [ 20 ] Ringworm is a fungal skin disease that in dogs is caused by Microsporum canis (70%), Microsporum gypseum (20%), and Trichophyton mentagrophytes (10%).
Microsporum gallinae is a cosmopolitan zoophilic fungi that very rarely affects humans. [10] It obtains nutrients from keratin-rich skin, nails and hair, releasing enzymes during its digestion that elicit a host immune response as seen in ringworm. [11] [12] Microsporum gallinae infection is diagnosed by culturing the scrapings from skin ...
Hence, animals, cats and dogs are believed to be the population hosts of this fungus, while humans are occasional hosts, in which the fungus can induce secondary infections. [4] Microsporum canis has been identified as a causal agent of a ringworm infection in pets, tinea capitis and tinea corporis in humans, children in particular. [2] [3] [5 ...
Zoophilic organisms are found primarily in animals and cause marked inflammatory reactions in humans who have contact with infected cats, dogs, cattle, horses, birds, or other animals. Infection may also be transmitted via indirect contact with infected animals, such as by their hair. [6] This is followed by a rapid termination of the infection.
Trichophyton verrucosum is very slow-growing compared to other dermatophytes. [4] In culture, it is characterized by being flat, white/cream colour, having an occasional dome, with a glabrous texture, known as the variant album, however other variations are also found: T. verrucosum var. ochraceum has a flat, yellow, glabrous colony; T. verrucosum var. discoides has a gray-white, flat, and ...
