NovaVive Amplimune MCWF Immunostimulant for Calves

Amplimune for Calves – MCWF Immunostimulant for E. coli K99 Scours

Amplimune is a USDA-licensed immunotherapeutic treatment for neonatal calves 1 to 5 days of age. It is indicated for the reduction of mortality and clinical signs associated with calf scours caused by Escherichia coli (E. coli) K99.

Amplimune contains mycobacterium cell wall fraction (MCWF), an immunostimulant that stimulates non-specific innate immune response early in the disease process. It is administered as a single 1 mL intravenous (IV) dose per calf.

This product may be used as part of a calf scours management program and is commonly used as an alternative approach to traditional antibiotic therapy for enterotoxigenic E. coli (ETEC) K99 diarrhea.

Indications & Key Benefits

• For calves 1 to 5 days of age
• Reduction of mortality associated with E. coli K99 scours
• Reduction of clinical signs of enterotoxigenic E. coli (ETEC) K99 diarrhea
• Single 1 mL dose per calf
• Supports innate immune response during early disease challenge
• Low-volume IV administration

Available Sizes

• 5 mL vial (5 single 1 mL doses)
• 20 mL vial (20 single 1 mL doses)
• 100 mL vial (100 single 1 mL doses)

Each calf receives one 1 mL intravenous dose.

How It Works

Neonatal calves have an immature immune system and may be highly susceptible to enterotoxigenic E. coli infections, especially in cases of failure of passive transfer (FPT). Amplimune stimulates non-antigen specific defense mechanisms, enhancing innate immune response during early disease challenge.
