Bacteria: Eat And Breathe Electricity

Last August, Abdelrhman Mohamed found himself hiking deep into the wilderness of Yellowstone National Park. Unlike thousands of tourists who trek to admire the park’s iconic geysers and hot springs every year, the WSU graduate student was traveling with a team of scientists to hunt for life within them. However, after a strenuous seven mile…

The Microbiota Controls Neutrophil Activity: Study Finds

A host protein called Serum Amyloid A (Saa) is a major factor mediating the effects of the microbiota; on the function of immune cells called neutrophils; according to a study published in the open-access journal PLOS Pathogens by John Rawls of Duke University School of Medicine, and colleagues. Experiments in zebrafish showed that Saa produced…

Fluconazole: Fungi Sexually Active

The yeast Candida albicans occurs in most healthy people as a harmless colonizer in the digestive tract. However, it can also cause life-threatening infections, especially in immunocompromised patients. These infections are usually treated with the drug fluconazole, which inhibits the synthesis of ergosterol in Candida. Ergosterol fulfils similar important functions in fungi as cholesterol in humans.…

Novel Enzyme: In Intestinal Bacteria

In the human intestinal system, a complex community of microorganisms, the intestinal microbiome, metabolizes food components that have not readily been digested. However, there are also microbial degradation processes occurring in the colon that may have negative effects on the human host. In the research team Microbial Ecology, headed by biologist Dr David Schleheck, a…

Machine Learning: To ID Source Of Salmonella

A team of scientists led by researchers at the University of Georgia Center for Food Safety in Griffin has developed a machine-learning approach that could lead to quicker identification of the animal source of certain Salmonella outbreaks. In the research, published in Emerging Infectious Diseases, Xiangyu Deng and his colleagues used more than a thousand…

2,000 unknown bacteria discovered in the human gut

Researchers at EMBL’s European Bioinformatics Institute and the Wellcome Sanger Institute have identified; almost 2000 bacterial species living in the human gut. These species are yet to be cultured in the lab. The team used a range of computational methods to analyse samples; from individuals worldwide. So, the results, published in the journal Nature; highlight…

Yeast & Fungi: Do These Benefit The Infant?

Investigators have now shown that the breast milk microbiome contains fungi. Multiple previous studies had found bacteria in breast milk. Certain fungi and bacteria have been shown to be important probiotics for infant health. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.”Our research demonstrates the presence…

Genes in bacteria

Genes Help Harmful Bacteria Thwart Treatment

A Rutgers-led team has discovered two genes that make some strains of harmful Staphyloccocus bacteria resistant to treatment by copper, a potent and frequently used antibacterial agent. The discovery shows that Staphyloccocus aureus can acquire additional genes that promote infections and antibacterial resistance and may open new paths for the development of antibacterial drugs, according…

Yeast study prompts rethink of DNA safekeeping

DNA replication is more prone to errors at times of stress leading to mutations that could cause disease. Cells go to great lengths to keep their genomes intact. But when resources are scarce, errors start creeping into the DNA code with potentially catastrophic consequences, new research suggests. At no time is the DNA more vulnerable…

In Human Microbiome: New Gut Bacteria Discovered

Scientists working on the gut microbiome have discovered and isolated more than 100 completely new species of bacteria from healthy people’s intestines. The study from the Wellcome Sanger Institute, Hudson Institute of Medical Research, Australia, and EMBL’s European Bioinformatics Institute, has created the most comprehensive collection of human intestinal bacteria to date. This will help…

Depression: Linked to Gut Microbiome

The human gut contains trillions of bacteria that form the gut microbiome or microbiota. A new research has linked the composition of this gut microbiome and depressive disorder. The study titled, “The neuroactive potential of the human gut microbiota in quality of life and depression,” was published in the latest issue of the journal Nature Microbiology this…

Microbes: The Coffee Maker

When it comes to processing coffee beans, longer fermentation times can result in better taste, contrary to conventional wisdom. Lactic acid bacteria play an important, positive role in this process. Other species of microbes may play a role in this process as well, but more research is needed to better understand their role. The research…
