Lactobacillus gallinarum is a species in the genus Lactobacillus.[1] Its type strain is ATCC 33199.
L. gallinarum is a native probiotic to chickens.[2] L. gallinarum adheres to the epithelial cells of the crop, ileum, and ceca of broilers.[3] L. gallinarum is most persistent in the ileum and ceca due to its sensitivity to bile.[4] Along with L. gallinarum, L. acidophilus, L. salivarius, L. fermentum, and L. reuteri, are found in high abundance in the ileum and crop of chickens.[3]
Lactobacillus gallinarum is a novel species of Lactobacillus, originally isolated from the crop of chickens.[5] Though closely related to other Lactobacillus species, L. gallinarum has evolved specifically to adhere to poultry epithelial lining, and is able to adhere to the chicken hepatoma cell line (LMH).[4]
Lactobacillus acts as a competitive inhibitor, preventing pathogens from colonizing the gastrointestinal tract. L. gallinarum, along with other Lactobacillus species, was found to reduce Salmonella in the ceca of broilers.[6] Salmonella free broilers were fed a Lactobacillus multi-species probiotic containing L. gallinarum. Twenty days after infection with Salmonella Enteritidis, there was significant reduction of the Salmonella in the ceca of probiotic fed chickens.[6]
