These Patescibacteria in the human oral microbiome reside on the surface of another, larger host microbe. Found in many water and land environments, Patescibacteria in general lack the genes required to make many molecules necessary for life, such as the amino acids that make up proteins, the fatty acids that form membranes, and the nucleotides in DNA. This has led researchers to speculate that many of them rely on other bacteria to grow. In a new study, researchers present the first glimpse into the molecular mechanisms behind their relationship with their host cells. They also share details gleaned from fluorescent, time-lapse microsopic imaging of these bacteria as they bud and send out swarms of tiny progeny, only a fraction of which are able to establish a host relationship.

After exposing the strains to components of the human immune system in a laboratory 'test tube' setting, scientists found that some strains were more likely to survive in blood and serum than others, and that neutrophils (white blood cells) are more likely to ingest and kill some strains than others.

Now, a 4-month randomized controlled trial in people with non-alcoholic fatty liver disease (NAFLD) indicates that daily intake of resistant starch can alter gut bacteria composition and lower liver triglycerides and liver enzymes associated with liver injury and inflammation.

Researchers developed their living material using a seaweed-based polymer and bacteria that have been programmed to produce an enzyme that transforms various organic pollutants into harmless compounds.

The research identifies gut microbiome features and early life influences that are associated with children developing any of four common allergies -- eczema, asthma, food allergy and/or hay fever. The findings could lead to methods of predicting whether a child will develop allergies, and ways to prevent them from developing at all.

The disease can also jump from animals to humans, mainly through consumption of unpasteurized dairy products or inhaling the spores from the tissues of infected animals. While the disease can cause arthritis, inflammation of the heart and flu-like symptoms in humans, the bacteria can also enter the brain and cause neurobrucellosis, which can lead to long-term neurological complications, headaches, nausea, disorientation, swelling of the brain and sometimes death. Now, a new study has highlighted the protective power of both innate lymphoid cells and specific signaling proteins, known as interferons, in reducing the harmful neurological effects of Brucella.

In fact, a study of Seattle-area women over age 50 who had not taken any antibiotics for at least a year discovered that the incidence of gut-colonizing ciprofloxacin-resistant E. coli actually increased. About 1 in 5 women in the study were affected. The results are consistent with theoretical models indicating that, once a drug-resistant form of E.coli emerges, it will continue to spread by taking up long-term residence in individuals' gut microbiomes. Antibiotic resistant E. coli in the gut is of concern because the bacteria can enter the urinary tract and cause difficult-to-treat infections, particularly in women. Evidence from studies such as this one may be changing paradigms on how to fight the rise in antibiotic resistance. 星期一,2023年8月28日22:38:07美国东部时间 //www.koonmotors.com/releases/2023/08/230828223807.htm //www.koonmotors.com/releases/2023/08/230825165925.htm Researchers have developed and demonstrated a new method for high-throughput single-cell sorting that uses stimulated Raman spectroscopy rather than the traditional approach of fluorescence-activated cell sorting.

Staphylococcus was prevalent on 85 percent of the wristbands; researchers found Pseudomonas on 30 percent of the wristbands; and they found E. coli bacteria on 60 percent of the wristbands, which most commonly begins infection through fecal-oral transmission.

For scientists, it is also where molecules or tiny building blocks meet to form materials. Researchers take it to the next level and use the energy of swimming bacteria to forge materials. A recent study shows us how this works and the potential sustainability benefits that may arise from this innovative approach.

Not only did they demonstrate the strategy's abundance, but they also discovered tools that control it and send signals that tell bacteriophage viruses to flip from chill (lysogeny) into kill (lysis) mode. They showed that in polylysogeny, phages can coexist, their viral DNA or RNA hidden tucked inside the bacterium's own, replicating right along with the cells. But the infiltrating phages aren't exactly peaceful; it's more like mutually assured destruction. And the tenuous detente lasts only until something triggers one or more of the phages to switch into kill mode.

In some species, mothers produce a special type of nutrient-rich skin that juveniles consume, similar to the way in which humans breastfeed their children. A new study shows this behavior passes on microbes to juvenile caecilians, inoculating them to jump-start a healthy microbiome.
