Microbiologists investigated the microbiome of a sessile free-living ciliate Stentor coeruleus. This is one of the first studies addressing prokaryotic communities associated with unicellular eukaryotes through metagenomic analysis.
The discovery could one day let doctors prevent the infection by allowing E. coli to pass harmlessly through the body.
Researchers have shown that three genes from a probiotic Lactobacillus species, used in some commercial probiotic vaginal capsules, are almost certainly involved in mediating adhesion to the vaginal epithelium. This is likely critical to how this species benefits vaginal health.
Cooperative study conducted by University of Jyväskylä and Natural Resources institute Finland (Luke), revealed that enriched rearing of juvenile fish significantly enhances the survival of fish from bacterial infection commonly seen in rearing conditions. That may also improve the post release survival of the fish after stocking into the wild. The study has been published in Journal of Applied Ecology.
Bacteria, like people, have complicated relationships. A group of researchers was able to engineer the genomes of 4 species of gut bacteria to make them rely on each other for essential nutrients rather than competing for them, and the whole community was stronger and more balanced as a result. This technology could enable bacteria-based therapies and tools that could be used to improve human health, produce valuable substances, or repair microbial ecosystems.
Staphylococcus aureus bacteria are a major cause of serious infections that often persist despite antibiotic treatment, but scientists at the UNC School of Medicine have now discovered a way to make these bacteria much more susceptible to some common antibiotics.
A higher standard of wastewater treatment in the UK has been linked to substantial improvements in a river's biodiversity over the past 30 years. The Centre for Ecology & Hydrology analysed data from the regular monitoring of both chemicals and invertebrates in the River Ray in Wiltshire -- downstream from Swindon's large wastewater treatment plant - between 1977 and 2016.
Research conducted at the University of Hawai'i (UH) at Mānoa School of Ocean and Earth Science and Technology (SOEST) on a marine sponge in Kāneʻohe Bay, Oahu revealed a unique feeding strategy, wherein the sponge animal acquires important components of its diet from symbiotic bacteria living within the sponge.
To combat the rise of drug-resistant bacteria, researchers in Houston are examining how one superbug adapts to fight an antibiotic of last resort. They're hoping to find clues that can prolong the drug's effectiveness.
Bacteria can swim against the current -- and often this is a serious problem, for example when they spread in water pipes or in medical catheters. An international research team was able to answer this question: With the help of experiments and mathematical calculations, a formula was found that describes all essential aspects of this amazing bacterial motion behavior. This could make it possible to prevent or at least slow down the spread of bacteria by designing special tube surfaces.
