A defective intestinal tight junction barrier, sometimes known as "leaky gut," plays an important role in exacerbating and prolonging intestinal inflammation. New research reported in The American Journal of Pathology, published by Elsevier, shows that the probiotic Lactobacillus acidophilus (L. acidophilus) strain known as LA1 can generate a rapid and sustained enhancement of this defective intestinal barrier and effectively treat intestinal inflammation by preserving and restoring the intestinal barrier.
Handwashing is shaping communities of bacteria that live and grow in the plumbing of domestic sinks, scientists have found.
Researchers from the Max Planck Institute for Chemical Ecology and the University of Mainz, together with an international team, showed that the genome of symbiotic bacteria of beewolves is in the process of being reduced to their important protective function: the production of antibiotics. The bacterial genome is of great interest for understanding genome erosion and elucidating how the cooperation between bacteria and their host insects has evolved over long periods of time.
The downward trajectory of plant and animal diversity constitutes a key issue of the Anthropocene. Whether diversity is changing also in the world of microbes is unknown, however -- a "profound ignorance" -- because the importance of these microorganisms maintain Earth's habitability. A paper published today frames the rate of change of microbial biodiversity as an important question on which progress is possible.
Collaborative research of the University of Jyväskylä and Natural Research Institute Finland presents new evidence of the effects of enriched rearing on well-being of aquaculture fishes. The research demonstrates that stone enrichments that have been previously conditioned in lake water significantly improve survival of fish compared to clean stones. Also a higher number of stones has a similar positive effect. The results have practical implications for prevention of aquaculture diseases. The study was published in Antibiotics in March 2021.
Australian pineapple, Danish trout, and Midwestern U.S. corn farmers are not often lumped together under the same agricultural umbrella. But they and many others who raise crops and animals face a common problem: excess nitrogen in drainage water. Whether it flows out to the Great Barrier Reef or the Gulf of Mexico, the nutrient contributes to harmful algal blooms that starve fish and other organisms of oxygen.
To better understand how RNA in bacteria gives rise to protein--and potentially target these processes in the design of new antibiotics--researchers are turning their attention to the unique way this process happens in bacteria. University of Michigan researchers have directly observed previously hidden RNA regulatory mechanisms within bacteria. The results are published in PNAS.
A study led by researchers at the University of Campinas reinforces the need for prevention and follow-up treatment starting in early childhood to avoid development of this inflammatory disease of the gums.
The extent to which the composition of the microbiome of apples and oil pumpkins depends on the geographical location and what insights can be derived from this for breeding, health and shelf life of the fruits is shown in two recent publications by researchers at TU Graz.
A team of UBC Okanagan researchers has determined that the type of fats a mother consumes while breastfeeding can have long-term implications on her infant's gut health.Their study suggests that the type of fat consumed during breastfeeding could differentially impact an infant's intestinal microbial communities, immune development and disease risk.
