Vaccine For Sore Mouth In Sheep

Sore mouth is caused by a virus. It commonly affects nursing or recently weaned lambs, but sheep of all ages can be affected. The disease is characterized by the formation of lesions, which progress into thick crust or scabs, on the lips. Often, an entire group of lambs will become infected. However, mortality is low.

Sore mouth is spread by direct contact. The incubation period depends on the amount of virus present and varies from 8 to 10 days. Lesions begin as small red spots on the lips, and scabs develop two or three days later. Occasionally, the nostrils, eyelids, and mouth also are involved. When the scabs are prominent on the lips, lambs may eat less because eating is painful. Loss of body weight can be noticeable. Occasionally, a lamb might die from starvation or secondary pneumonia induced by sore mouth. Nursing lambs may spread the infection to the teats of the ewes. When this occurs, it is not unlikely for mastitis to follow. Use extreme care and sanitation in treating infected sheep because the virus can affect humans. Lesions are sometimes found on the hands and faces of people working with infected sheep.

Description

Treating sheep with sore mouth has not proven very effective. However, applying a topical antibiotic ointment may help reduce the potential for secondary infection. Commercially available vaccines also can be used on infected premises or in feedlots to prevent sore mouth. Apply vaccines as directed on the label. Generally, the application entails creating a small lesion (scratch) on the inside of the thigh, and applying the vaccine to the lesion. Vaccination of lambs at tail-docking time is a good management procedure. Vaccinate show flocks at least one month before the beginning of the show season. Ovine Ecthyma (Sore Mouth) Vaccine is recommended for vaccinating both sheep and goats against disease caused by ovine ecthyma virus or against sore mouth infection.

Features of Vaccine For Sore Mouth In Sheep

Ovine Ecthyma (Sore Mouth) Vaccine is recommended for vaccinating both sheep and goats against disease caused by ovine ecthyma virus or against sore mouth infection. Dosage: 1 drop to 1″ scarified area. Do not vaccinate within 21 days of slaughter.

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.

Treatment

No specific treatment is available for scabby mouth but generally affected animals recover spontaneously with scabs healing in about 3–4 weeks. Try to determine what is damaging the skin and allowing the virus entry, and remove the source. Where harsh dry feed is a problem, provide sheep with a softer, more palatable feed. It is also important to monitor animals for flystrike and secondary infection. If scabby mouth is occurring regularly in a feedlot, consider either starting a vaccination program or moving the feedlot to a new site.

Prevention

While animals infected with scabby mouth usually recover uneventfully, it is particularly important to ensure animals being supplied for export do not have scabby mouth (see below). Animals previously infected with scabby mouth develop immunity provided there is regular exposure to the virus. A live vaccine which introduces a controlled volume of live virus to the sheep is available to protect against scabby mouth. To apply it, scratch the bare skin on the inside of the leg or brisket with a special applicator. Follow the vaccine manufacturer’s recommendations carefully as correct vaccination technique is important for development of protective immunity. The vaccine produces a ‘take’, a small row of pustules that appears along the vaccine scratch line, mimicking natural infection.
