Pathogen Control

Lactobacillus acidophilus and BT1386

• L. acidophilus is a lactic acid producing bacteria.
• In the rumen, this can lead to more rapid adaptation of the rumen microbes to lactic acid and increase the number of lactic acid utilizing bacteria.
• It has been recently shown that L. acidophilus BT1386 is also effective in reducing the number of both acid sensitive and acid resistant E. coli O157:H7 present in rumen fluid:

Beyond Rumen Health

• The health benefits of intestinal pathogen inhibition in livestock through direct-fed microbial feeding are seen not only in increased efficiency in the animal, but serve as a pre-harvest food safety intervention.
• A recent University of North Dakota study showed that feeding L. acidophilus resulted in:

• A 32% reduction fecal shedding of E. coli O157:H7 among the steers treated with the Lactobacillus Acidophilus BT1386.
• Steers being almost three times less likely to shed E. coli in their feces when compared to steers fed no direct-fed microbial.

• A significant reduction in the probability of new infections with Salmonella.
• This pathogen inhibition occurs by attachment of L. acidophilus BT1386 bacteria to intestinal surface, thereby inhibiting the attachment and proliferation of pathogenic bacteria in the intestine, and through production of lactic acid that causes a reduction in pH in the intestine.
