The study developing a mathematical model; that showing how bias distorts results when measuring bacterial communities through metagenomic sequencing. The proof-of-concept model could be the first step toward developing calibration methods; that could make metagenomic measurements more accurate. Metagenomic sequencing identifies the number and type of bacteria present in a particular community for example, in a…
A new study in healthy adults suggests that antibiotics; may reduce the effectiveness of the flu vaccine. The depletion of gut bacteria by antibiotics appears to leave the immune system less able to respond to new challenges, such as exposure to previously unencountered germs or vaccines. This is the first demonstration of the effects of…
According to the study, microbiologist showing that disease causing bacteria; compete with their human hosts for a key micronutrient. Although queuine (pronounced KYOO-in) has been identified as essential to human health a 2018 study by Bruce Ames referred to it as a longevity vitamin much is still unknown about the compound; that humans must obtain…
The research study discovering antibiotic resistance does not spread only where; and when antibiotics are used in large quantities, ETH researchers conclude from laboratory experiments. Reducing antibiotic use alone is therefore not sufficient to curtail resistance; and should be done in conjunction with measures to prevent infection with resistant germs. Bacteria are becoming increasingly resistant…
Bacteria usually clone themselves to reproduce, but they are also known to swap DNA. A donor bacteria cell can transfer genes to a recipient cell in a process called lateral gene transfer, which can happen through three mechanisms: transduction, conjugation, and transformation. The research group thinks this DNA exchange (and transformation in particular) could be governed…
According to the study this showing the role of environmental factors; and internal regulation in determining the growth of an organism. As the body size of a living creature has a direct impact on its fitness from the simplest animal and plant organisms right up to human beings. The individual size or height is therefore…
The bacteria attacking phages could provide clues to antibiotic resistance; In fact that army bacteria-attacking viruses known as phages outnumber bacteria nearly ten-fold; making them the most abundant biological entity on earth. They are intricately adapted to invading; weakening and controlling their targets; then keeping them alive long enough to feed off them and use…
The study exploring the impact of gut bacteria on gut health; certain gastrointestinal bacteria cause disease in some people but not others. By this underlying the mechanisms responsible for this impact. Findings from this research should help to improve; the targeting of measures aimed at preventing gastrointestinal diseases. The human gastrointestinal tract is colonizing by…
The study explaining that the threat of the antibiotic resistant strains of infection is an escalating global health concern; and improving targeting of antibiotics is crucial in reducing the spread of resistance. But current susceptibility testing methods typically take two to three days to arrive back with a GP from hospital laboratories because they rely…
Studying the main obstacle in microbiology had been the fact; that it is not always possible to grow microorganisms in laboratory conditions in fact; it is thought that the majority of microorganisms which exist are unculturable. This leads to a bias when examining environmental microorganisms in the laboratory, where a group of organisms will rapidly…
The study showing that bacterial sex driving evolution of microbes to conquer; and colonize the gut in the body. Bacterial sex drives evolution of microbes to conquer and colonize the gut. This discovery constitutes a paradigm shift and opens the possibility to design phage targeting therapies capable of dealing with the aftermath of infection and…
The study stating that the adaptation to life inside cattle; may be driving Escherichia coli to develop harmful features. A large-scale study of the genetic differences and similarities among E. coli bacteria from cattle; and humans indicates that features causing food poisoning in humans; may continuously be emerging in bacteria from cattle as a means to…
