In a study announced on May 21, 2007, at the 38th annual Digestive Disease Week conference, a naturally occurring bacteria (Bifidobacterium infantis 35624) showed anti-inflammatory properties in a mouse model of arthritis.
This bacteria has previously been shown to modulate the inflammatory response in a clinical trial in irritable bowel syndrome. Data released from this study indicate that the probiotic (a potentially beneficial bacteria or yeast) may have anti-inflammatory action outside of the digestive tract.
Researchers at the National University of Ireland in Cork fed four different bacterial strains to mice that are specially bred to develop collagen-induced arthritis, a model of rheumatoid arthritis. The mice were fed the bacteria for at least two weeks before induction of arthritis. Of the four bacterial strains, only Bifidobacterium infantis 35624 delayed the onset of arthritis and resulted in less severe arthritic symptoms.
The results of this study have not yet been published in a peer-reviewed medical journal. The data need to critically reviewed by other scientists before any conclusions can be drawn.
