“Tick Toc”

The clinic phone rings…………………Hello………..Oh my gosh I woke up this morning and found ticks in my bed!!!!!!!!!!!!! How did they get there??? This is so disgusting!! Yuck, Ick….what can I do??

Yep we get those calls frequently. Ticks definitely have a big “Ick” factor. Ok so we all agree that ticks are totally gross. Besides being very good at creeping people out what true medical significance do they represent?

That’s the purpose of this series on ticks and tick borne diseases. We all need to be well-informed. Know thy enemy! Ticks are not only gross – they carry diseases like Lyme, Rocky Mountain Spotted Fever, Anaplasmosis, Ehrlichiosis, and  Babesiosis.

Yeah I know that you have probably never heard of most of these diseases but that is because they are spread by ticks and NE Ohio has been pretty much tick free…..until recently. Believe me you and your pets do not want any of these diseases!

I cannot explain why Ashtabula County had always been relatively tick free. The “experts” always thought I was simply stupid or incompetent when I would explain to them that our tick population was negligible to the point of almost nonexistent. To the bug guys this was absurd.

Well they didn’t live and practice veterinary medicine here. I am a lifelong resident of Ashtabula County and have spent most of my life in the outdoors as well as having practiced veterinary medicine here for 36 years. And I am telling you the number of ticks was simply irrelevant….. until a few years ago.

All that has changed in the last few years and now we are seeing a rapid explosion of ticks throughout the region. It began in the extreme north-east by Conneaut and now is basically everywhere.

The primary hosts for ticks are deer. One white tail deer can support enough tick reproduction to add 750,000 ticks to the environment next year. Enough said. They are carried around by birds. Birds are highly mobile and they migrate. Enough said.

We have identified several different types of ticks here. The black-legged tick or commonly called the deer tick, the Lone Star tick and the American Dog Tick are the most common. By far the dog tick is the one most commonly found by people. This is because they are present in large numbers and are quite big so people easily find them.

Let’s review some tick facts and fallacies.

Ticks are bugs. Bugs lay eggs (thousands of eggs) which hatch into larvae, which turn into young adults called nymphs which finally become adult ticks. This four stage life cycle can take up to 3 years to complete and involves a wide variety of hosts.

A host is the animal upon which the tick lives and feeds on their blood. The only thing ticks eat is blood. They are slow feeders and consequently stay attached to the host for long periods. The larvae, nymphs and adults are all blood feeders. They have an anesthetic in their mouth parts so the host doesn’t even feel the bite. Pretty treacherous isn’t it!

The larvae and nymphs prefer to feed on small mammals and birds. This may take two years. The nymph deer tick must feed on the white footed mouse in order to become infected with Lyme disease. We have these mice in NE Ohio. Sometimes they will also get on a larger mammal such as a dog or human. They are primarily responsible for spreading Lyme disease. These nymphs are very small and hard to see.

The adult ticks prefer large mammals such as deer, people etc. It is here that they complete their life cycle mating etc. and finally drop off to deposit eggs in the ground so the whole process can start over.

The American Dog Tick is the most common tick reported in Ohio. It is most active April through July is quite large and is responsible primarily for transmitting Rocky Mountain Spotted Fever. I have personally had Spotted Fever and believe me you do not want it. I got from a tick bite in Southern Ohio many years ago.

The next most common tick in Ohio is the black-legged or deer tick. This is a very small but very dangerous tick which spreads Lyme Disease, Anaplasmosis, Ehrilichiosis and Babesiosis. Dogs and humans are most impacted by these diseases. I believe many more species are affected as well but we aren’t looking for it in other species.

As I have already said the larvae and nymphs prefer small mammals and birds but they are opportunist like all parasites and will feed on people, pets and livestock given the chance. The adults prefer to feed on large mammals like us, dogs and deer.

Even the adults are tiny and hard to see. The nymphs and larvae are even smaller. This makes it very unlikely that you will find them on heavy coated animals. They are hard enough to find on your own skin.

The larvae and nymph deer ticks are most active in the spring and early summer. The adults are active late summer and fall.

The Lone Star Tick is more common in southern Ohio but we are beginning to find them here as well. They are most active April through August and they transmit two diseases to pets and people. These are Ehrlichiosis and STARI (Southern Tick Associated Rash Illness). These ticks are relatively large like the American Dog Tick.

Myths and Facts

Myth: Ticks jump or fly.

Truth: Ticks are rarely found above your knees. They wait on grass or brush for a host to pass. Upon detecting the host body heat they wave their front legs around and grasp onto a hair or thread then climb on. Deer ticks do not have eyes………..so jumping is out of the question!

Myth: A hot match, fingernail polish, rubbing alcohol, or petroleum jelly will cause a tick to back out.

Truth: None of this works. They will only allow the tick to remain alive and attached longer increasing the risk of disease transmission.

Stay tuned for the next article about tick prevention.

Lyme Disease and Ticks

A series to educate people about this emerging health threat in North East Ohio

By: Dr. Charles Curie DVM

Country Doctor and Geneva Veterinary Clinics Ticks

Representative Patterson hosted a Lyme symposium in conjunction with the Lyme Bites support group. The symposium was held at Ashtabula Kent State University Campus and was attended by nearly 100 people from NE Ohio. I was one of the speakers on the panel.

Most in attendance had been directly or indirectly affected by Lyme disease. The testimonials were heart wrenching. Lyme disease is nothing to take lightly and unfortunately it is most often misdiagnosed in humans.

I think we were all moved to near tears by the testimony of a brave 14-year-old girl named Megan who had been confined to a wheel chair because of Lyme disease. Now under the care of a Lyme literate physician she is slowly improving and can now stand and walk again.

Another young woman from Perry told her story about her three children who contracted Lyme disease from her in utero. This is where an infection is transmitted to the unborn fetus. She had no idea that she was infected. The children were misdiagnosed for a long time until she finally pieced the puzzle together and took them to a Lyme specialist in Connecticut. They are all making some progress now.

I shared with the audience the unbelievable rise in ticks and Lyme disease which I have witnessed at my two veterinary clinics. Both the Country Doctor Vet Clinic in Jefferson and the Geneva Vet Clinic in Geneva have experienced an absolute explosion in the number of ticks and Lyme infected dogs.

This is a new phenomenon for North East Ohio. I was born and raised here. I have literally spent my life pursuing outdoor activities with a passion and have practiced veterinary medicine here for the last 36 years. I never dealt with ticks until 6 or 7 years ago.

At that time we began seeing the tick population emerge in the Conneaut area. Initially it was just very sporadic reports. However now it is rampant.  The ticks are spreading from east to west and now moving south. We are now seeing many ticks from South County as well, Andover, Williamsfield, Orwell, Rome, Rock Creek. They are everywhere.

We are finding ticks on animals from Conneaut to Perry in amazing numbers. Last year I found my first Jefferson tick on a dog which had never left the village. This year it is becoming more common in Jefferson. We have people in the northern part of our practice areas who tell us they remove 10 -15 ticks from their dog every time they go out in the yard.Ticks in dogs ears

And yes I said the yard! These are not farm dogs that are running the fields and woods. They are pets who live in town. Of course the farm and hunting dogs are even more exposed to ticks and Lyme disease.

We have recently diagnosed numerous cases of Lyme disease in dogs and all but one of these lived in town. The exception was a farm dog from the Monroe township area.

These dogs are sick! They have swollen joints, enlarged lymph nodes, lameness, lethargy, depression and poor appetites. Fortunately they have all responded well to treatment. But the long-term effects are yet to be seen.

The purpose of this series on Ticks and Lyme disease is to make the general public aware of these new realities here in NE Ohio. They are here to stay. Nobody can make them go away and the problem is only going to get worse. You can count on that.

It is my goal to make every one Tick and Lyme literate. Know thy enemy! We all need to learn about ticks and Lyme in order to protect ourselves, our family and our pets. We need to be smarter than the bug.

Ticks and Lyme are new to us but they are nothing new to the North East and North West United States. We can learn so much from the knowledge already discovered in these endemic areas.

The next article in the series we will discuss what makes ticks …………tick!

Happy Halloween

Posted on Updated on

The thing about blogging is you need to figure out what you want to blog about, and to be truthful I don’t feel comfortable blogging. Not yet anyway but maybe it will be something that will grow on me as I go along. I sure hope so! Anyway I’m sitting here thinking that today is Halloween. There are many important topics about this spooky day that pet owners should be aware of, but instead of blogging about them I think I’ll talk about my problems. Why doesn’t anyone respond to fantastic promos (in my opinoin) that we come up with for clients and their pets.

Today is Halloween and we came up with a pretty simple idea to celebrate it. Stop into the clinic with your pet and receive a treat if your pet is dressed up we will take its photo and post it on face book. At the end of the day the pet with the cutest costume will receive a goodie bag! This sounds simple and easy right? I thought so but it is 10:30 am and no one has yet walked through our doors. I’m so sad, it seems so easy to me I mean who wouldn’t want a treat for their pet? Who doesn’t want to see their pet’s photo on face book? Of course I’m clueless as usual. Does anyone else ever have these great ideas (in my opinion) and it flops?

Maybe I’m over reacting I mean it is only 10:30 am! There is still hope that we will get cute little ghost and goblins through our door. I hope so because this is a part of the job that is so much fun, getting to socialize with clients and their pets. Well keep your fingers crossed just maybe this event will not be a flop! Wait I think I hear the door open, could it be….?

Hello is anyone out there?

Posted on Updated on

Okay, so this is kinda of a test? Considering the fact that I have been trying to get a blog up since March. I recognize that I am not social media savvy, but I’m really not as dumb as word press makes me feel! OK, great this feels good, I pray it works or my co-workers may find my body at my desk because I’m afraid of what I may do if it doesn’t.

That being said we would like to welcome you to our blog, we hope it continues but I can’t promise anything! We will attempt to keep blogging about veterinary issues, whatever they may be from all points of view. Some blogs will be funny, some serious and some informative. You’ll just have to follow us to find out! Thanks for reading this far and welcome.
