Mycobacterium Paratuberculosis Bacterin

Mycopar is a whole cell bacterin containing inactivated M. paratuberculosis bacteria suspended in oil. For vaccination of calves as an aid in the control of clinical disease due to Mycobacterium paratuberculosis. Vaccination will confer protection against clinical disease, but does not necessarily prevent infection.

Shake the vial well prior to withdrawing the contents. Administer the 0.5 mL dose subcutaneously to healthy calves less than 35 days of age in the brisket-dewlap area. A granulomatous lesion may develop at the injection site. To avoid injury or trauma to this lesion, it is recommended that the injection be made in the dewlap approximately 1 inch above the brisket. Proper restraint of calves must always be exercised.

In the United States, distribution and administration of the product in each state is limited to veterinarians designated by State Animal Health officials. Only replacement heifer and bull calves, between one and 35 days of age, shall be vaccinated in herds participating in a State program.

Store at temperatures between 0° and -5°C for extended periods, but between 2° and 7°C for a maximum of one year prior to use.

The use of a biological may produce allergic reactions. The antidote is Epinephrine.

Do not vaccinate within 60 days before slaughter.

Caution: In the event of accidental human exposure by inoculation of the bacterin, the possible hazard to human health should be considered. State public health officials should be consulted for specific recommendations.

Accidental inoculation of humans may cause an intense granulomatous reaction. Granulomas may occur not only at the site of injection but may also metastasize if adjuvant enters the blood stream. The extent of lesions is dependent upon subsequent trauma to the area. Literature and reports from experienced physicians indicate curettage or total excision of the lesion is the only effective treatment. Every reasonable effort should be made to remove the bacterin from the freshly inoculated area by thorough washing (and suction). Do not squeeze or traumatize the site.
