Bacterial Superbug MRSA Arose in Hedgehogs Long Before the Use of Antibiotics Began
The findings are not a reason to fear hedgehogs, say the researchers. Credit: Pia B. Hansen Scientists have found evidence that a type of the antibiotic resistant superbug MRSA arose in nature long before the use of antibiotics in humans and livestock, which has traditionally been blamed for its emergence. Hedgehogs carry a fungus and…
Bacterial Builders Churn Out Lengthy Muscle Proteins
Bacteria may soon be muscling in on new kinds of manufacturing. Researchers have developed a technique that uses the common bacterium Escherichia coli to synthetically produce a muscle protein called titin, which could someday build tough and pliable fibers. Uses could range from medical sutures to impact-resistant or biodegradable fabrics. The titin is dozens of…
Assemblages of bacterial communities depend on depths in paddy soils
Depth effects on bacterial community assembly processes in paddy soils. Credit: Li Weitao Bacterial communities in soil play a key role in carbon (C) and nutrient cycling. It is not clear how geographic divergence in bacterial community composition depends on soil depth, which processes underlie community assembly, and which are the main factors. In a…
