Lyme Disease
(Borreliosis)
Lyme Disease is a bacterial disease affecting both humans and animals.
It is caused by a corkscrew-shaped spirochete called Borrelio burgdorferi
and spread by ticks - the deer tick (Ixodes dammini) in the northeast USA.
Different named ticks spread the disease in other parts of the country.
In 1975 the disease was first reported in humans in the U.S. The cases
were in Lyme, Connecticut, from whence it gets its name. In 1984 it was
discovered in dogs. It has spread rapidly and is in almost every state,
each year claiming more victims.
Ticks are bloodsucking parasites. When an infected tick bites it's victim,
the bacteria is transferred into the blood of the human or dog. Clinical
signs of Lyme disease in dogs are sudden lameness or pain, arthritis, fever,
depression, lethargy and loss of appetite, but other symptoms may occur.
It is not unusual for dogs with Lyme disease to differ in their symptoms.
The same is true in humans.
After walking your dog or dogs, particularly in wooded areas or high
grass, go over the dog dogs carefully and feel for ticks. For dogs with
heavier coats, you will have to use a brush or comb. If you search promptly
on returning home, you can sometimes find the ticks before they are attached
to the animal. However if they are attached, promptly remove the tick with
tweezers, being careful to remove the whole tick, including the mouth.
Wash the areas with betadine and be sure to wash your own hands. If you
find a small deer tick, mark the date on your calendar. Remember not all
deer ticks are infected. If any unusual symptoms occur, you can report
to your veterinarian the date you removed the tick.
To protect your animals, be sure to mow regularly and keep brush areas
cut in your yard, trimming any long grass where ticks hide waiting for
a host.
Several broad spectrum antibiotics have proven effective in the treatment
of Lyme disease - such as Ampicillin, Tetracycline, ect. - which should
be given as directed by your veterinarian.
Many people bitten by an infected deer tick develop a round circle around
the bite mark, but not everyone. Dogs do not develop such symptoms and
therefore should be watched carefully for signs of lameness, lethargy,
ect.
Even following treatment for Lyme disease, when your dog is acting normally,
the animal should be watched for a recurrence which happens with some dogs,
but not all of them.
Ticks are active until the temperature drops below 40 degrees F. so
be aware of this fact and observe your dog. Contact your veterinarian immediately
should you suspect your dog has Lyme Disease or is exhibiting any unusual
symptoms. The sooner the dog is treated, the treatment is usually more
effective.
There is a vaccine available against Lyme Disease - recommended by some
but not all veterinarians. If your dog is in a high risk area and constantly
picks up ticks, perhaps you should discuss the vaccine with your veterinarian.
