Some bacterial pathogens, including those that cause strep throat and pneumonia, are able to create the components necessary to replicate their DNA without the usually required metal ions. This process may allow infectious bacteria to replicate even when the host’s immune system sequesters iron and manganese ions in an attempt to slow pathogen replication. A […]Continue Reading ...
A newly discovered toxin that some bacteria deploy to fend off competing bacteria stands out from others in the battle for microbial domination. While many deadly substances have been identified among bacteria, this previously unknown toxin behaves in a familiar way. “What is special about this toxin,” noted UW Medicine microbiologist Brook Peterson, “is that […]Continue Reading ...
In the fight against drug-resistant bacteria, MIT researchers have enlisted the help of beneficial bacteria known as probiotics. In a new study, the researchers showed that by delivering a combination of antibiotic drugs and probiotics, they could eradicate two strains of drug-resistant bacteria that often infect wounds. To achieve this, they encapsulated the probiotic bacteria […]Continue Reading ...
A new study from the University of Helsinki shows that babies that are breastfed for at least six months have less antibiotic-resistant bacteria in their gut compared with infants breastfed for a shorter time. In addition, antibiotic use by mothers increases the number of antibiotic-resistant bacteria in infants. A recent study completed at the University […]Continue Reading ...
To fight your enemies, it helps to know their weaknesses. And, the more specific your knowledge, the easier it is to undermine their defenses. If your enemy sits safe behind a giant wall, for example, its valuable to know how your foe constructed it, what materials they used, and what cracks you could exploit. We […]Continue Reading ...
A new study from National Institutes of Health scientists and their Thai colleagues shows that a “good” bacterium commonly found in probiotic digestive supplements helps eliminate Staphylococcus aureus, a type of bacteria that can cause serious antibiotic-resistant infections. The researchers, led by scientists at NIH’s National Institute of Allergy and Infectious Diseases (NIAID), unexpectedly found […]Continue Reading ...
Approximately $1.7 million in new funding from the National Institutes of Health will enable a multidisciplinary team of University of Illinois at Chicago researchers to build a reference library of bacteria to help scientists quickly identify bacterial strains and analyze their disease-fighting potential. Coupled with a novel web-based bioinformatics pipeline, the researchers hope the library, […]Continue Reading ...
During a nationwide outbreak of healthcare-associated infections of an antibiotic-resistant bacteria, an Israeli hospital traced repeated infections of patients in its intensive care unit (ICU) to an unexpected source–sink traps, according to a study published today in Infection Control & Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. “Understanding the source […]Continue Reading ...
Dr Alan Yu and Associate Professor Seth Masters. Credit: Walter and Eliza Hall Institute of Medical Research Australian researchers have uncovered clues in the immune system that reveal how the balance of ‘good’ gut bacteria is maintained. The information could help in the prevention and treatment of inflammatory bowel disease (IBD). The study, published in […]Continue Reading ...

The bacteria hide from antibiotics inside the very immune cells that are supposed to kill them, making treatment long and difficult. But in the November issue of ACS Infectious Diseases, UConn chemists report a new antibiotic that can find and […]Continue Reading ...

Carnegie Mellon University researchers have identified a molecule that plays a key role in bacterial communication and infection. Their findings add a new word to pneumococcus’ molecular dictionary and may lead to novel ways to manipulate the bacteria and prevent infection. The findings, from the lab of Associate Professor of Biological Sciences Luisa Hiller, are […]Continue Reading ...
Tuberculosis is a sneaky disease. The bacteria hide from antibiotics inside the very immune cells that are supposed to kill them, making treatment long and difficult. But in the November issue of ACS Infectious Diseases, UConn chemists report a new antibiotic that can find and kill tuberculosis bacteria where they hide. Tuberculosis is the number […]Continue Reading ...
A team of researchers are gathering bacteria from across the world to create a microbiota vault that would preserve the myriad of strains of bacteria that inhabit the human gut and other mucosal levels. Image Credit: urfin / Shutterstock The bacteria that will be stored in the vault play a major role in the immune […]Continue Reading ...
