Tick-borne Diseases: Lyme Disease by Dr. Carter

Following the lead of our colleague, Dr. Miller, we will take a closer look at Lyme disease, our area's most common tick-borne disease. Lyme disease (named for the Connecticut town) has been around for over a century but did not gain public notoriety until the 1980s. The Northeastern US and upper Midwest represent disease “hotspots,” but with warming temperatures, the disease is spreading. While we see scattered cases throughout our clinic's areas, the Goose Lake region especially represents a regional/local hotbed. Lyme disease is caused by a bacterium, Borrelia burgdorferi, which is transmitted by Ixodes ticks, in our area better known as the deer tick.

Lyme disease, or Borreliosis, while also a well-known human disease, manifests itself differently in our canine patients. Greater than 90% of dogs who are infected with the organism are not “sick” because of it and are asymptomatic. In dogs, the disease may not manifest itself for weeks to months after infection and they may present with signs of arthritis or perhaps a fever. Fortunately, symptoms of the disease respond quickly to a course of appropriate antibiotics. Although rare, the most serious potential long-term effect is kidney disease. Due to this potential risk, in some cases we may recommend a urinalysis be checked to look for any possible indications of kidney involvement. Lastly, while cats may become infected with the organism, they appear more resistant to its effects, do not develop clinical signs and currently, the disease is not regarded to be of clinical concern in our feline patients.

As noted earlier, the deer tick transmits the bacterium, causing infection. There are three life stages involved: larvae, nymph and adult, that utilized various-sized 'hosts' for their feeding (blood sucking!). These hosts range from small (white-footed mouse) to large (dogs, deer, humans) depending on the life stage of the tick. Not surprisingly, the mouse and deer are quite prevalent in our area. Whit the tick feeds on its host, it requires a minimum of 48 hours to pass the bacterium, thus, if the tick is removed within 48 hours of attachment, the bacterium cannot be transmitted and the host will not get the disease.

Diagnosis of Lyme disease is confirmed through blood testing. When performing our recommended yearly heartworm testing, the test also checks for three tick-borne diseases: Lyme, Ehrlichiosis and Anaplasmosis, the latter two being less common in our are. Remember, simply having a positive result does not constitute illness. However, if the patient is exhibiting joint pain and maybe a fever, we may prescribe a course of antibiotic therapy. Treatment does not eliminate the organism, it will remain in a low latent state, similar to the 90% of infected dogs who do not experience illness.

Tick control is the hallmark of Lyme disease prevention. Ticks can be active year-round and continuous protection is recommended. We carry and utilize monthly topical applications or a new chewable monthly medication, all of which kill ticks before they can transmit disease. In addition to these products, vaccination offers additional protection against Lyme disease. The vaccine inactivates the bacterium within the tick. While we do not vaccinate ever canine patient, it is recommended for patients who reside in regional hotspots, those individuals whose lifestyle is higher risk such as hunting dogs, or individuals who travel to other geographical hotspots such as Wisconsin.

Remember, prevention is the key to protecting both our canine companions AND their human friends, as we take to the woods and fields in our area!

Cats! by Dr. Joachim

 It is no secret that I am a cat lover. Don't get me wrong, dogs are great, too, but there is a special place in my heart for the furry felines (and the not so furry, for that matter...I'm looking at you sphinxy)! I could go on to say that if they happen to be orange this only ups the ante. The staff here for the most part knows that if there is an orange cat in the facility I am to be notified right away. The technicians have gone out of their way to come out of an exam room to plop an orange cat in my lap, especially when they know I am having a particularly stressful day. I owe my love for cats to my own orange cat, Oliver. I adopted him my first year of vet school, and he has been with me ever since. He was my shadow all throughout vet school; keeping me company while I spent countless hours studying, even if only to sleep on his bed next to my desk till all hours of the night and early morning...and in true cat fashion to often sleep ON my desk or ON my books, keyboard, lap, back of my desk chair, etc. (cat people, you know what I am talking about)! 

Now that I am part of the family at Pine Bluff Animal Hospital, I have been working on educating myself about a cat-friendly practice. There are 86 million owned cats in the US and 78 million owned dogs yet there are twice as many cats than dogs that never see a vet. 39% of people say they would only bring their cat to the vet if the cat was sick. It is just as important that a cat sees us at least yearly for health checks and preventative care such as vaccines, fecal tests, etc. Senior cats, cats that go outdoors, have exposure to outdoor cats, or already have chronic diseases such as Feline Immunodeficiency Virus (FIV or feline AIDS) and/or Feline Leukemia Virus (FeLV) are among the many that should visit the vet even more frequently than just the basic yearly health checks. Just because a cat is healthy as perceived by their owner does not mean it does not need to see a vet. We see sick AND healthy pets and checking in with our fantastic felines once a year can increase the likelihood that we will catch an early disease state while it is still manageable.

Some of the hallmarks of a cat-friendly practice are found in the waiting room and traced all the way to the very back of the hospital where pets are boarded. Staff that is knowledgeable about the least stressful restraint and handling techniques and understand the little idiosyncrasies of cats can make all the difference in our feline visits. We've already made some small changes at our hospitals and will be working towards more in the coming months. My ultimate goal is to increase our feline visits by making them as minimally stressful on our owners AND their special cats. In the meantime, I encourage you to bring your cat in if it hasn't been seen by a vet in awhile (or ever). And if it is orange...be prepared :)
