This treatment applies to the following species:
Company: Colorado Serum

Ovine Ecthyma Vaccine, Live Virus

U.S. Vet. Lic. No.: 188

Active Ingredient(s): Contains dried ovine ecthyma vaccine and a bottle of sterile rehydrating fluid labeled as sterile diluent.

Penicillin and streptomycin are added as preservatives.

Ovine Ecthyma Vaccine Indications

Recommended for vaccinating both sheep and goats against disease caused by ovine ecthyma virus or against sore mouth infection.

Dosage and Administration

It is advisable to vaccinate each new lamb and kid crop because dried scabs retain the infective virus which is resistant to heat and cold and can be expected to survive from year to year. Exposure to infection can occur during shipping. Range lambs moving into feedlots should be vaccinated at least 10 days before shipment to prevent the spread of the disease after arrival.

Normally only healthy animals should be vaccinated but experience has shown that in outbreaks of sore mouth, vaccination of the infected sheep and lambs tends to shorten the course of disease.

OVINE ECTHYMA VACCINE is a live virus vaccine. Do not use within 24 hours of dipping or spraying.

Rehydrating: Rehydrate the vaccine just prior to use. Contents of the diluent vial may be withdrawn with a sterile syringe and needle, without removing the stoppers, and transferred to the bottle of dried vaccine. If a syringe is not convenient the aluminum seals may be pried off the bottles with a pocket knife and the diluent poured into the vaccine bottle.

Shake the vaccine bottle until the dried virus substance is completely restored to liquid form. Live virus products contain a stabilizer that may slow rehydration slightly but complete liquefaction will take place within a few moments. The vaccine is then ready to use. When rehydrating the vaccine use only the diluent that is supplied with the product.

The bottle of vaccine contains 100 doses. Select a wool free area of skin, such as the inside of the flank and scarify the outer layer by scratching with the notched handle of the applicator furnished as a part of the package. Scratching need not be deep enough to cause bleeding but should be sufficient to adequately roughen the skin. An area of at least one (1) square inch should be scarified. The vaccine can be applied by dipping the brush into the vaccine bottle or by placing a drop of vaccine on the scarified area and brushing vigorously.

Reddening and a slight swelling of the site of administration should be observed a few days after vaccination. This will develop into raised areas that will rupture and scab over representing a take that indicates successful vaccination. Scabs will dry and fall of in about three (3) weeks.

Precaution(s): Store in the dark at 2-7°C. Do not use chemical disinfectants with the vaccine.

Use the entire contents when the bottle is first opened. Burn the container and all unused contents.

Caution(s): Humans have been accidently infected with ovine ecthyma virus. Lesions that have been described in man are most often on the hands and arms. Usually such infections are not serious but all individuals handling the vaccine should take precautions against infecting themselves with the virus.

Brushes and scarifiers should be used only in a single flock of sheep. If there is a need to use the instrument a second time, it should be sterilized by boiling in water for several minutes.

For veterinary use only.

Warning(s): Do not vaccinate within 21 days before slaughter.

Discussion: Ovine ecthyma (sore mouth) is a contagious disease of sheep and goats caused by a virus. Most commonly this is characterized by vesicular and pustular lesions that progress to the formation of thick scabs on the lips or the skin. The disease exists wherever sheep and goats are raised.

Infected suckling young may transmit the infection to the udder of susceptible ewes. Sores on the mouths of the young and on the udders of the ewes greatly limits feeding and there is a severe economic impact from loss of weight and condition. Uncomplicated cases heal spontaneously in four to five weeks, usually without treatment. If secondary bacterial infections and maggot infestation develop, such invaders can cause fatalities ranging from 10 to 50 percent of the animals.

Treatment is difficult. In small flocks scabs can be removed and the lesions cleansed of maggots. A penetrating antiseptic may be of limited value with respect to bacterial infections. The use of a fly spray will help to restrict maggot re-infestation.
