Pets that chase rodents, especially into burrows, might be at an increased risk.A.D.A.M., Inc. Since fungi are everywhere it is almost impossible to prevent exposure. In some pets the disease may resolve by itself. Our doctor will let you know if they are needed in your case. These include ketaconazole and itraconazole. Oral anti fungal medications are also used in select cases. Specific anti fungal cremes are also used when a pet is infected in an area that already has sparse hair growth, or there are small, discrete lesions. These baths will also remove infected hairs that can be the source of an infection to people or other animals. It is common to clip some or all of the hair in some pets to make it more effective. Topical shampoo therapy is used in almost every case, especially in longer haired pets. Positive fungal growth after 10 days of incubation at room temperature. The culture media prior to the start of the test. This color change must occur at the same time the fungal growth appears. The first is the cottonish fungal growth, and the second is the reddish color of the culture media. The positive culture on the right, from our in-house lab, demonstrates two findings that are needed for a positive diagnosis. Since a fungus is a slow growing organism it can take up to four weeks to determine if there is growth or not. This culture can be sent to our outside lab or done in-house. These hairs are cultured in a special media that inhibits bacterial growth and enhances fungal growth. The first step in the culture process is to gently remove hair follicles in the area of the lesion 50% of the Microsporum canis species will fluoresce when the Woods lamp is placed near the area of hair loss. One of the simplest ways to diagnose Ringworm is with the Woods lamp, which is an ultraviolet lamp, also know as a black light. We will culture these pets using the culture technique we describe below, but in this case, we might run a new toothbrush over the hair coat to obtain a sample for culture. This is especially important in multiple cat households. If a person in a household has been positively identified with Ringworm by their physician it is possible they obtained it from their pet, even if their pet has no symptoms of the disease. This concept holds true for all skin conditions making a diagnosis of a skin disease requires all of the aspects of the diagnostic process. All require some type of test because it is impossible to make the diagnosis just by looking at the skin. There are several different ways to diagnose Ringworm. A diagnosis of this disease can not be made based just on the appearance of this lesion because other skin conditions ( Demodex for example) can show similar lesions. This patch is typical of the lesion seen in Ringworm. If the hair loss occurs on the face or feet there is a chance it is due to digging habits or exposure to rodents. There might be scratching due to itchiness. as time goes on the patches may disappear or appear at other locations on the skin. There will be hair loss, usually in small patches at first. The skin lesions that appear with Ringworm are variable, and do not necessarily form a ring. Which of these 3 main dermatophytes causes the Ringworm in dogs depends on geographic location. In dogs the majority of cases are caused by Microsporum canis. ![]() In cats, almost all cases of Ringworm are caused by Microsporum canis. ![]() Trichophyton mentagrophytes – This species infects dogs and cats when they are exposed to rodents or the burrows they live in.Microsporum gypseum – This species of Ringworm is usually from dogs and cats that dig into contaminated soil.Microsporum canis – The source of this species of Ringworm is almost always a cat.There are 3 specific fungi of significance in this disease: A dog or cat can transmit Ringworm to a person without showing any symptoms at all. People will sometimes pick up a case of Ringworm from their pet, but just because a pet has Ringworm does not necessarily mean that the people that interact with that pet will develop the problem. We tend to see the problem more in young animals. These pets might be carriers of the disease to other pets along with people. The fungus that causes Ringworm can be cultured from the hair coats of normal dogs and cats. Since fungi are everywhere in our environment, it is difficult to determine what pets will develop the problem. The scientific name for this disease is Dermatophytosis. Ringworm is caused by a fungus, not a worm, and the lesion is not always in the shape of a ring.
