Salmonella choleraesuis Vaccine

U.S. Vet. Lic. No.: 337

Active Ingredient(s): NITRO-SAL is an avirulent live culture offering protection to swine against naturally occurring field strains of Salmonella choleraesuis. NITRO-SAL is preserved as a frozen preparation.

Nitro-Sal Indications

Recommended for the subcutaneous vaccination of healthy, susceptible swine five weeks of age or older against disease caused by Salmonella choleraesuis. Pigs must be free from any outside stresses at the time of the vaccination.

Dosage and Administration

Thaw the vaccine at room temperature just prior to the vaccination. Shake well before using. Inject 1/2 mL subcutaneously at five (5) weeks of age or older.

NITRO-SAL will provide a successful vaccination, but the immune response in the pigs also depends upon the administration techniques, previous exposure to immunosuppressing agents and the environment.

Precaution(s): Store the frozen vaccine at a temperature of 14°F (-10°C). Freezing maximizes the number of organisms preserved and viability at the time of administration.

Trial Data: Twenty randomly selected four to five week old pigs were vaccinated subcutaneously with a dose of Salmonella choleraesuis vaccine (NITRO-SAL). Twenty more randomly selected pigs were held as controls. All of the pigs were challenged with a laboratory Salmonella culture from the National Veterinary Services Laboratory.

Results: All of the control pigs experienced clinical disease. Fourteen pigs died. Six pigs survived for two weeks exhibiting typical signs and lesions of salmonellosis. The vaccine provided protection to the vaccinated pigs. Clinical problems were not detected in the vaccinated pigs.

The field evaluation of NITRO-SAL in Salmonella choleraesuis infected herds resulted in reduced mortality, improved feed conversion and increased rate of gain. One shot protection provides a means of controlling a significant swine disease.

Presentation: 20 dose, 50 dose, 100 dose, and 500 dose.
