Erysipelas Vaccine For Pigs

Erysipelothrix Rhusiopathiae Vaccine, Avirulent Live Culture Ingelvac® ERY-ALC is a safe, effective, one dose, live Erysipelothrix rhusiopathiae (erysipelas) vaccine. It is administered orally. Ingelvac® ERY-ALC is recommended for the vaccination of healthy, susceptible swine 8 weeks of age or older as an aid in the prevention of disease caused by Erysipelothrix rhusiophathiae (erysipelas). Infectious disease caused by E rhusiopathiae in pigs is known as erysipelas and is one of the oldest recognized diseases that affect growing and adult swine. Up to 50% of pigs in intensive swine production areas are considered to be colonized with E rhusiopathiae. The organism commonly resides in the tonsillar tissue. These typical healthy carriers can shed the organism in their feces or oronasal secretions and are an important source of infection for other pigs. Infection is by ingestion of contaminated feed, water, or feces and through skin abrasions. When ingested, the organism can survive passage through the hostile environment of the stomach and intestines and may remain viable in the feces for several months.

On farms where the organism is endemic, pigs are exposed naturally to E rhusiopathiae when they are young. Maternal-derived antibodies provide passive immunity and suppress clinical disease. Older pigs tend to develop protective active immunity as a result of exposure to the organism, which does not necessarily lead to clinical disease. Recovered pigs and chronically infected pigs may become carriers of E rhusiopathiae. Healthy swine also may be asymptomatic carriers.

Description

Erysipelas in swine is caused by the bacteria Erysipelothrix rhusiopathiae and is found in most if not all pig farms worldwide. It is reported that up to 50% of animals may carry the bacteria in their tonsils which is why the disease continues to affect pigs worldwide, with economic losses stemming from disease outbreaks or animals being condemned at slaughter. The bacteria is always present in either the pig or in the environment because it is excreted via saliva, feces or urine making it nearly impossible to eliminate exposure to the herd. Infected feces is likely the main source of infection, particularly in growing and finishing pens. While the bacterium itself can cause Erysipelas, virus infections such as Porcine Reproductive and Respiratory Syndrome (PRRS) or swine influenza, may trigger Erysipelas outbreaks as well.

Erysipelas is uncommon in pigs under 8-12 weeks of age due to protection provided by maternal antibodies from the sow via the colostrum. The most susceptible however are growing pigs, non vaccinated gilts and up to 4th parity sows. Once the bacterium enters the body, the organism multiplies in the body invading the bloodstream resulting in septicemia. This multiplication blocks tiny blood vessels to the skin over the back and sides causing thrombosis. The result of this restricted blood supply, are visible small raised areas on the skin and abdomen that appear diamond shaped. The rapidity of multiplication and the level of immunity in the pig determines the clinical symptoms expressed as acute, subacute or chronic disease presentations.

Benefits of Erysipelas Vaccine For Pigs

  • Long duration of immunity, at least 128 days.
  • Aids in the prevention of disease caused by Erysipelothrix rhusiopathiae (erysipelas)

Dosage

Administer 1 dose in the drinking water to each pig. Thaw contents of vaccine bottle by placing bottle in trickling cool water bath until liquid (usually 30-40 minutes). Shake well and use entire contents immediately. See product insert for completedirections.

Administration

Each specific vaccine has a specific dose rate and administration protocol that must be followed if the vaccine is to be effective. The range of vaccines used in the herd will affect protocols but for the most important vaccines for the smaller producer, the following guidelines are applicable.

E.coli/Clostridial disease- combined vaccines exist (eg Porcilis 6C : Intervet Schering Plough, Gletvax6 : Zoetis) designed to be administered to the gilt/sow prior to farrowing with protection passed on to the piglets via colostrum. Two 5ml doses are required as a primary course with a specified interval between the two doses, the second dose given up to two weeks prior to farrowing. In subsequent parities a single booster dose is required two weeks prior to farrowing. (NB – sheep can be a reservoir for clostridial infection.) E.coli only vaccines also exist and require the same protocols for administration. However due to the more extensive husbandry that tends to apply in small herds the combination products are advisable. (NB – sheep can be a reservoir for clostridial infection and when kept with pigs the disease risk for both can be higher. Both species should be vaccinated with appropriate vaccines)
