Ticks and Vector borne Diseases
Lyme Disease is transmitted by the deer tick (often referred to as the black-legged tick) and the western black legged tick. The disease is an infection of the skin tissue that often leads to lameness. Lyme disease is zoonotic and can be very serious for both people and pets.
In general, symptoms in dogs are difficult to detect and may not appear until several months after infection. Also, symptoms may come and go and can mimic other health conditions. Cases vary from mild to severe with severe cases sometimes resulting in kidney failure and death.
What Are the Symptoms of Lyme Disease?
A “bull’s eye” rash at the site of the tick bite is common with human Lyme disease infection. Dogs have no such indicator. In fact, a dog infected with Lyme disease may show few if any signs, but some of the more common symptoms of this disease can include any of the following:
- Spontaneous and shifting leg lameness that lasts 3 to 4 days, sometimes accompanied by loss of appetite and depression
- Reluctance to move
Common areas to find Lyme Disease
The most common areas to find Lyme Disease is commonly found in many areas across Australia and throughout the United States and Canada. The most frequently infected areas in the United Stares are diagnosed in the North Eastern states, Mid Atlantic, North Central states and most of California.
Is there a treatment for Lyme Disease ?
Patients treated with appropriate antibiotics in the early stages of Lyme disease usually recover rapidly and completely. Most patients recover well with early treatment of Lyme disease. When treated with a few weeks of antibiotics taken orally, patients can recover quite quickly.
Antibiotics commonly used for oral treatment include doxycycline, amoxicillin, or cefotaxime axetil. Patients with certain neurological or cardiac forms of illness may need intravenous treatment with drugs such as ceftriaxone or penicillin.
In a small percentage of cases, these symptoms can last for more than 6 months. Although sometimes called “chronic Lyme disease,” this condition is properly known as “Post-treatment Lyme Disease Syndrome” (PTLDS).
Vector borne Zoonotic Diseases and Human Activity
Several articles, warn that human activities are spreading vector borne zoonotic diseases. The Lancet have published a number of articles about vector borne zoonotic diseases and their effects on humans. These articles discuss how rapid changes in land use, trade globalization, and “social upheaval” are causing a resurgence in zoonotic disease around the world.
Examples of vector-borne zoonotic diseases include:
Many factors affect the incidence of vector borne diseases. These factors include animals hosting the disease, vectors and people.
Humans and Zoonotic Diseases
Humans and non-canine family members can also become infected with the same tick borne diseases as dogs. Zoonotic is the cross over species of these diseases. If you live in an area infected by ticks or if you have ever found a tick on your pet, you should also check yourself and your family.
Pets and Tick Bites
There is simply no way for pet owners to tell if a tick is carrying disease or not. It only takes one tick bite to infect your dog. Ticks can carry more than one of these diseases. This can lead to multiple infections, or co-infection.
What is common among all vector borne diseases, however, is that symptoms can be vague and difficult to recognize. As a result, pet owners often don’t know their pet is suffering from a debilitating tick disease until it is too late.
