Eye Illness in an Animal Model improved by an Oral Probiotic Bacterial Strain
animal model of dry eye illness was found to be improved by ingestion of a
readily accessible probiotic bacterial strain in a study by a research team at
Baylor College of Medicine. The results have been presented at ASM Microbe
2023, the American Society for Microbiology’s annual meeting. One in twenty individuals suffer from
dry eye, an issue in which the tears generated by the eye are insufficient to
fully lubricate the eye. It may result in inflammation, eye itching and
burning, vision impairment, and light sensitivity. If severe cases go
untreated, the surface of the eye may be harmed. Applying eye drops, gels, or
ointments is one of the most popular therapies. The intestinal tract’s bacteria
are involved in this novel, unusual treatment. “The
‘friendly’ bacterium that inhabit the gastrointestinal tract of humans are
being associated with wellness and defence from infection in numerous areas of
the human body, including the intestines, nervous system, and lung,”
stated the presentation’s author Laura Schaefer, Ph.D., of Baylor College of
Medicine in Houston, Texas. As a result, it is not strange that the gut
microbiota also influences our vision. Previous studies by the aforementioned
group demonstrated that animals given gut bacteria from Sjögren syndrome
patients with extremely dry eyes who also had severe eye disease under dry
settings had worse eye disease than mice who were given gut bacteria from
healthy human patients. This shows that in dry conditions, the exterior of the
eye is protected by the gut bacteria of healthy individuals. Probiotic
microorganisms with comparable protective benefits could be one approach to
treating dry eyes.
Kalinga Plus is an initiative by Kalinga University, Raipur. The main objective of this to disseminate knowledge and guide students & working professionals.
This platform will guide pre – post university level students.
Pre University Level – IX –XII grade students when they decide streams and choose their career
Post University level – when A student joins corporate & needs to handle the workplace challenges effectively.
We are hopeful that you will find lot of knowledgeable & interesting information here.
