What is Vesticular Stomatitis?

What is Vesticular Stomatitis?

Vesicular Stomatitis

Vesicular stomatitis is a viral disease that primarily affects cattle, horses, swine and occasionally sheep and goats. Humans can also become infected with vesicular stomatitis when handling affected animals.

Vesicular stomatitis is most likely to occur during warm months in the Southwest, particularly along riverways and in valleys. The Southwestern United States experienced a vesicular stomatitis outbreak from May 1998 through January 1999. It is essential that veterinarians and livestock owners be on the alert for animals displaying clinical signs characteristic of the disease.

In affected livestock, vesicular stomatitis causes blisterlike lesions to form in the mouth and on the dental pad, tongue, lips, nostrils, hooves, and teats. These blisters swell and break, leaving raw tissue that is so painful that infected animals generally refuse to eat or drink and show signs of lameness. Severe weight loss usually follows, and in dairy cows, a severe drop in milk production commonly occurs. Affected dairy cattle can appear to be normal and will continue to eat about half of their feed intake.

Epidemiology:

Vesicular stomatitis has been confirmed only in North and South America. It is known to be an endemic disease in the warmer regions of the Western Hemisphere, but outbreaks of the disease occasionally occur in temperate geographic areas.

How vesicular stomatitis spreads is not fully known; insect vectors, mechanical transmission, and movement of animals are probably responsible. One type of vesicular stomatitis virus is known to be spread by phlebotomine sandflies. Once introduced into a herd, the disease apparently moves from animal to animal by contact or exposure to saliva or fluid from ruptured lesions.

Humans can contract vesicular stomatitis when handling affected animals if proper biosecurity methods are not followed. Prevalence of this disease in humans may be underreported because it may often go undetected or be misdiagnosed. In people, vesicular stomatitis causes an acute influenza-like illness with symptoms such as fever, muscle aches, headache, and malaise.

Why is it so important to promptly recognize animals with vesicular stomatitis?

We live in an area where this disease has often been seen in past years, and in fact Fort Collins was the epicenter of the last U.S. outbreak in 1998. Thus, we have an increased risk of seeing cases in Colorado this year as cases have recently been confirmed in horse premises in Texas and New Mexico. Vesicular stomatitis is recognized internationally as a reportable disease, which means that there are serious economic and regulatory repercussions associated with the diagnosis, and several countries have already taken action to block movement of U.S. horses as a result of the TX and NM cases. If a VS case were diagnosed at the VTH and it appeared that transmission might have occurred within the VTH then we could be quarantined for several months. In 1998, the average duration of quarantine of affected premises was 120 days, and it was generally longer at large operations! Be on the look out for recent horse events.

While vesicular stomatitis can cause economic losses to livestock producers, it is a particularly significant disease because its outward signs are similar to (although generally less severe than) those of foot-and-mouth disease, a foreign animal disease of cloven-hoofed animals that was eradicated from the United States in 1929. The clinical signs of vesicular stomatitis are also similar to those of swine vesicular disease, another foreign animal disease. The only way to tell these diseases apart is through laboratory tests. Horse owners can also receive other treatments.

What are clinical signs of vesicular stomatitis?

In affected livestock, the incubation period for vesicular stomatitis ranges from 2 to 8 days. Often, excessive salivation is the first sign. Body temperature may rise immediately before or at the same time lesions first appear. Initially, close examination of the mouth reveals blanched and raised vesicles. If there are no complications such as secondary infections, then affected animals recover in about 2 weeks. Vesicular stomatitis does not generally cause animals to die.

Clinical signs of vesicular stomatitis and other vesicular diseases include:

Excessive salivation

Blanched raised or broken vesicles of various sizes in the mouth:

Horses: upper surface of the tongue, surface of the lips and around nostrils, corners of the mouth and the gums.

Cattle: tongue, lips, gums, hard palate, and sometimes muzzle and around the nostrils

Pigs: snout.

Lesions involving feet of horses and cattle are not exceptional.

Teat lesions occur in dairy herds.

Foot lesions and lameness are frequent in pigs.

Recovery in around 2 weeks.

Complication: loss of production and mastitis in dairy herds due to secondary infections, lameness in horses. Erosions and exudate in the nares. Cow drooling because of mouth lesions.

Erosions – ruptured vesicles – of the gingiva. Erosions on a teat. Erosions and dried exudate on the coronary band and heal.

Hyperemia and beginning erosions on the coronary bands.

Erosions – ruptured vesicles – on the tongue. Vesicles on the tongue.

What can we do to protect our animals?

There is no specific treatment or cure for vesicular stomatitis. Owners can protect their animals from this disease by avoiding congregation of animals in the vicinity where vesicular stomatitis has occurred. Mild antiseptic mouthwashes may bring comfort and more rapid recovery to an affected animal. Good sanitation and quarantine practices on affected farms usually contain the infection until it dies out of its own accord.

In order to protect our hospital and our patients, we will include appropriate questions related to vesicular stomatitis when taking all patient histories, and we will purposefully look for characteristic lesions when performing admission examinations for all susceptible patients. We will also ask the owners of susceptible animals to have their animal examined by a referring veterinarian for the presence of characteristic lesions within 48 hours before arriving at the hospital.

When a definite diagnosis of vesicular stomatitis is made on a farm, the following procedures are recommended:

Immediately contact your local veterinarian or State or Federal animal health authorities.

Separate animals with lesions from healthy animals, preferably by stabling. Animals on pastures apparently are affected more frequently with this disease.

As a precautionary measure, do not move animals from premises affected by vesicular stomatitis—unless they are going directly to slaughter—for at least 30 days after the last lesion found has healed.

Implement on-farm insect control programs that include the elimination or reduction of insect breeding areas and the use of insecticide sprays or insecticide treated eartags on animals.

Use protective measures when handling affected animals to avoid human exposure to this disease.

Not just horsing around: Beverly Smith-Embry found her niche providing insurance for horse owners

Small Business Snapshot

Author: Ed Green
Business First Staff Writer

Beverly Smith-Embry thinks most insurance jobs sound boring. But by starting an insurance agency in an unusual niche, she found a way to enjoy her work.

Beverly A. Smith-Embry, president of Smith-Embry Insurance Associates Inc.

Beverly A. Smith-Embry, president of Smith-Embry Insurance Associates Inc.

“Every once in a while, you need a horse fix when you are dealing insurance papers on a day-to-day basis,” said Smith-Embry, an independent insurance agent who exclusively writes policies for horse owners. “You feel like you are overwhelmed with paperwork, so it’s nice to be able to get out and see a horse other than at the racetrack.”

Smith-Embry Insurance Associates Inc., was founded in 1991. Besides Smith-Embry, the agency has two other employees: Chuck Smith, her son, and Tamara Embry, her sister-in-law.

Smith-Embry said she never expected to work in the equine insurance industry until she found a job as an assistant for Edward McGrath, the former owner of E.J. McGrath Insurance Co. He wrote equine insurance policies for Lloyd’s of London and other insurers of Thoroughbred racehorses.

She joined McGrath’s firm in 1978 and left the agency not long after McGrath sold it in 1991. She had helped sell insurance to owners of many well-known Thoroughbreds, including Kentucky Derby winners Affirmed and Genuine Risk.

That experience gave her connections to the equine industry and the motivation she needed to form her own agency later in 1991, she said.

Her initial efforts involved “going to the Keeneland sales and going to the horse sales in Ocala, Fla.,”

“Once it is in your blood, it is kind of hard to leave because it is kind of an exciting career. It is insurance, but kind of with a little twist,” Smith-Embry said.

A big difference in her job and typical insurance sales is that it’s difficult to determine the insurable value of horses. That is because that value is based not only on the price the owner paid for the horse and its breed but also criteria such as its potential earnings and its value to the individual client’s business.

“Every year, you have to reapply for coverage and determine the value” of the horse, she said. “It’s my job to make sure we are valuing them correctly in a way that keeps the (insurance) company happy and the client happy.”

Smith-Embry talks about her agency, which is a breed apart

Are most of your clients Thoroughbred owners?

“No. It is very, very competitive. … The competition in the Thoroughbred industry makes it really difficult to get into. So, I decided you have to go where the business takes you. There are a lot of other breeds, and we focus mostly on those. A lot of my clients have breeding farms” for show horses and breeds such as Arabians and Saddlebreds.

Do you own horses?

“No. My husband and I were in one of those little racing partnerships for a while. He loves that end of it, and I, sitting in my chair, see that you hear about the people who make money … but you don’t hear about all the money you have to put in to make money.
