New species of antibiotic-resistant bacteria found in infected wound

A hitherto unknown antibiotic-resistant bacteria species, in the same family as E. coli and Salmonella spp., has been found and classified in Sweden. The proposed taxonomic name of the species—the first of the new genus—is Scandinavium goeteborgense, after the city of Gothenburg, where the bacterium was isolated and the research was done. Knowing which bacteria cause infections and which antibiotics […]

Have you been taking your gut health for granted?

Bacteria, fungi and viruses — collectively called microbiome — in the gastrointestinal tract perform many important functions in the body. For a body to function properly, it must maintain the right balance of bacteria in the gut. You may not be aware, but there exist bacteria, fungi and even viruses — collectively called microbiome — in the gastrointestinal tract. They […]

Immune cells in skin kill MRSA bacteria before they enter the body

A type of immune cell called neutrophils could be responsible for controlling bacterial numbers of an antibiotic-resistant strain of Staphylococcus aureus (MRSA) on human skin before the bacteria get a chance to invade, according to a new study from Karolinska Institutet published in Cell Reports. The results could provide an explanation for why this superbug is only carried transiently by […]

Resistant bacteria may be lurking in the washing machine

In commercially available washing machines can apparently survive multi-resistant germs and pieces of clothing to be transferred. This happened recently in a children’s hospital in Bonn: The pathogen, Klebsiella oxytoca, have been repeatedly found on a neonatal intensive care unit. The Transmission of the germs is only able to be stopped, as the washing machine was removed from the hospital. […]

Bacteria injections help the immune system fight cancer

Cancers evade destruction by convincing some immune cells to suppress others. But a surprising interlocutor can persuade the suppressors to defect, and the destroyers to redouble. A review published in Frontiers in Oncology explains how bacteria can rally immune cells to attack tumors, via ancient lines of chemical communication with our immune system. Decoding these molecular signals is key to […]

Diet impacts the sensitivity of gut microbiome to antibiotics, mouse study finds

Antibiotics save countless lives each year from harmful bacterial infections — but the community of beneficial bacteria that live in human intestines, known as the microbiome, frequently suffers collateral damage. Peter Belenky, an assistant professor of molecular microbiology and immunology at Brown University, studies ways to minimize this side effect, which can lead to C. diff infections and other life-threatening […]

Infecting mosquitoes with bacteria prevents them carrying dengue

Dengue fever ‘could be defeated’ by infecting mosquitoes with bacteria that makes it harder for them to spread the life-threatening virus Male and female mosquitoes exposed to bacteria Wolbachia in the laboratory Released into the wild, bred and produced Wolbachia-carrying offspring  Vietnam in particular has seen a ‘remarkable reduction’ in cases  Scientists have raised hopes dengue fever may one day be defeated […]

Climate change will raise Florida’s risks of brain-eating amoeba and flesh-eating bacteria

When it’s blisteringly hot outside, splashing in the ocean, a lake or even a swimming pool is a popular way to beat the heat. But as global temperatures rise, scientists say, so do your chances of catching a nasty—or even deadly—bug. The scary one making headlines this summer is Vibrio vulnificus, also dubbed in media reports as “flesh-eating bacteria.” Historically, […]

Superbug virulence regulatory mechanism revealed: Pave ways for developing new antibiotics

As antibiotic resistance is growing and posing a threat on public health, developing new antibiotics has become more urgent than ever. Researchers at City University of Hong Kong (CityU) have recently revealed the virulence regulatory mechanism in Pseudomonas aeruginosa, a superbug which is common in patients with a weak immune system and is resistant to many antibiotics. The findings pave […]

Bacteria engineered as Trojan horse for cancer immunotherapy

The emerging field of synthetic biology—designing new biological components and systems—is revolutionizing medicine. Through the genetic programming of living cells, researchers are creating engineered systems that intelligently sense and respond to diverse environments, leading to more specific and effective solutions in comparison to current molecular-based therapeutics. At the same time, cancer immunotherapy—using the body’s immune defenses to fight cancer—has transformed […]
