Helpful Buckeye appreciates the patience and understanding shown by all of our readers as a consequence of the necessity of changing the format for last week's issue of Questions On Dogs and Cats. Actually, the "Snow Bound...." issue allowed for the opportunity to run a few informative pieces of information that otherwise might have not fit in with our regular weekly topics. Helpful Buckeye appreciates all the e-mails about the different topics last week.
If you haven't already read the title for this week's issue, you might be thinking this photo is from one of the science fiction movies so popular today. No, this is something that some of you may have experienced yourself or perhaps your dog and/or cat had the misfortune to encounter. This is a dermatophyte....more about this later in this issue.
Questions On Dogs and Cats is bringing back the weekly poll question this week. We haven't run a poll question for a couple of weeks and it was nice to get so many e-mails asking why not. Due to the structure of the 2 previous issues, it just wasn't feasible. So, be sure to answer this week's poll question in the column to the left.
As a reminder, readers can send an e-mail to Helpful Buckeye at: email@example.com and you can also register a comment at the end of each issue by clicking on the "Comment" icon and proceeding as directed.

DISEASES, AILMENTS, AND MEDICAL CONDITIONS
Sometimes the name of a disease can be misleading. This week's featured disease is one of those. Ringworm doesn't always have to appear as a round ring and it for sure does NOT involve a worm. The name ringworm arose several hundred years ago when early physicians thought the circular lesions on humans were the result of a skin worm infestation.
Ringworm in dogs and cats is caused by a small group of fungus organisms. There are numerous fungal infections seen in dogs and cats, ranging from the more serious systemic (affecting the entire body, mainly the internal organs) diseases like Histoplasmosis, Blastomycosis, Cryptococcosis, and Coccidiodomycosis to the more superficial skin infections like ringworm. In dogs, ringworm can be cause by any of 3 species of fungus, with 70% of infections being caused by Microsporum canis. In cats, 98% of ringworm infections are caused by Microsporum canis.
The main mode of transmission for ringworm is by direct contact with another infected animal or with a human who has the disease. Ringworm can go from human to animal, animal to animal, and from animal to human (zoonotic). Fungal spores from infected animals can be shed into the pet's environment and survive on their own for more than a year. These spores can be found in carpeting, bedding, furniture upholstery fabric, and on grooming equipment that has been used on an infected animal. Contact with these items can also lead to the spread of ringworm.
The clinical appearance of ringworm varies from animal to animal. The characteristic circular appearance seen in humans isn't always the way it appears on dogs and cats. These photos show the classic appearance usually seen in humans:
Even though this circular form can be seen in dogs and cats, the lesions can also be irregular in shape. Dogs usually show a scaly patch of skin that is devoid of hair or perhaps has just a few broken hairs present. These lesions may or may not be itchy and the exposed skin may or may not be reddened and inflamed. They are most commonly found on the face, ears, tail, and paws, but can be on the torso as well. There may be infected pustules present, especially in the center of the lesion. Cats usually don't show much of the itchiness, reddening, or infected pustules and most ringworm infections are found on the ears, face, and legs. This photo of a dog with ringworm shows a fairly large affected area on the torso in addition to the spot on the tail.
This photo of a cat with ringworm shows the more typical location of the hairless spots.
The diagnosis of a ringworm infection would be accomplished by your veterinarian as part of the examination. There are 3 main tests for determining if ringworm is the culprit behind the skin problem of your dog or cat. The first of these is called a Wood's lamp, which is a type of ultraviolet light also known as a black light. About 50% of ringworm infections will give off a fluorescent yellowish-green glow when illuminated by the Wood's lamp and that would be indicative of a ringworm infection. However, the other 50% of ringworm infections will not cause this glow. The second test involves mixing a sample of the broken and surrounding hairs with a chemical and examining the preparation with a microscope in search of actual fungal elements. Again, this method doesn't always produce diagnostic results. The most reliable and accurate test involves culturing some of the scales, crust, and hairs from one of the spots in a special culture medium that turns red when a ringworm infection is present. This test takes a few to several days to complete, so the results aren't known for a while. The positive result is on the right:
Veterinarians can perform all of these tests in the office.
As far as treatment is concerned, most of the smaller lesions on healthy animals will heal on their own within 2-4 months. The only problem with this wait-and-see approach is that there is the concern of the fungal infection being contagious to other pets or the humans in the household. The resolution of these infections can be sped up by certain treatments. Your veterinarian has several types of medications available for consideration, depending on many factors. Since most dogs and cats are healthy enough to never get infected with ringworm, an infected pet needs to be evaluated for any other possible health complications before treatment is begun. There are several types of rinse and shampoos available, although their overall effectiveness has never been confirmed. There are also a few creams which do provide effective treatment for individual lesions. For the truly chronic or severe cases, your pet might require some of the systemic medications, which are usually given orally. These also have the additional concern of certain side effects which your veterinarian would have to discuss with you.
Every pet owner should be aware of the signs, possibility of transmission, and treatment of ringworm in their dog and/or cat.
There has been a lot of news coverage of the terrible aftermath of the earthquake in Haiti and many of the rescue stories are heartbreaking. One small, but very important, aspect of the rescue effort has been the canine search-and-rescue teams. This is a summary of those efforts presented by Matthew Margolis, who, among other endeavors, reports on dog stories for NPR.
