A study published by Brazilian researchers describes one of Xanthomonas citri's secretion systems and a signaling pathway that enhances its resistance against amoebae. Investigations might contribute for future forms of intervening and putting a stop on the development of X. citri, known for its persistency.
In response to antibiotics, a gene regulation network found in the bacterium Acinetobacter baumannii acts to boost both virulence and antibiotic resistance. Edward Geisinger of Tufts University School of Medicine and colleagues present new insights into this system in a study published in PLOS Pathogens.
Researchers have recently published results identifying the major sources of E. coli breakouts on several beaches on Lake Michigan. They have also researched an effective method of reducing the breakouts and the resulting beach closings.
Clear, plastic aligners have been growing in popularity as alternatives to bulky, metal braces. And once the teeth are straightened, patients graduate to plastic retainers to maintain the perfect smile. But these appliances can become contaminated, so one group is now reporting in ACS Applied Materials & Interfaces that they have developed a film to prevent bacteria from growing on them.
Antimicrobial resistance (AMR) is a major medical problem worldwide, impacting both human health and economic well-being. A new strategy for fighting bacteria has now been reported in the latest online issue of Nature by a research group headed by Professor Ivan Dikic at the Goethe University Frankfurt. The scientists revealed the molecular action mechanism of a Legionella toxin and developed a first inhibitor.
So much for survival of the fittest -- diversity is the key: a team of researchers from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) has succeeded in demonstrating experimentally that genetic diversity makes populations more resistant to disease.
Antimicrobial resistance is on the rise worldwide. This is becoming a problem for infectious diseases like tuberculosis as there are only a few active substances available to combat such diseases. Pharmacists at Martin Luther University Halle-Wittenberg (MLU) have now found a way to increase the efficacy of a common tuberculosis agent while, at the same time, reducing resistance to it. The research group presents its latest developments in the international journal Molecules.
The large and small, beautiful and bizarre are among the newly discovered animals, plants and microbes announced by the College of Environmental Science and Forestry (ESF) as the Top 10 New Species for 2018.
The mechanism our immune cells use to clear bacterial infections like tuberculosis (TB) might also be implicated in Parkinson's disease, according to a new study. The findings provide a possible explanation of the cause of Parkinson's disease and suggest that drugs designed to treat Parkinson's might work for TB too.
Most of what we know today about deadly bacteria such as Pseudomonas aeruginosa was obtained from studies done in laboratory settings. Research reported May 14 in the journal Proceedings of the National Academy of Sciences shows that this laboratory-based information may have important limits for predicting how these bugs behave once they've invaded humans.
