Among obese women undergoing cesarean delivery, a postoperative 48-hour course of antibiotics significantly decreased the rate of surgical site infection within 30 days after delivery, according to a study.
Bacteria release membrane-derived vesicles (MVs), which are small particles that can transport virulence factors to neighboring bacteria or to the cells of a mammalian host. This special MV-based system for delivering toxic proteins and nucleic acids in a protected manner to the target cells may have different specific functions depending on whether the bacterium acts as an extracellular or intracellular pathogen.
In mice, an infection-induced condition known as sepsis may increase the risk of life-threatening secondary infection by preventing recruitment of infection-fighting cells to the skin, according to new research.
Nearly one out of every three humans on earth has a lifelong infection with the brain-dwelling parasite Toxoplasma gondii. In a new report, researchers from multiple institutions describe efforts to learn how infection with the parasite Toxoplasma gondii may alter, and in some cases amplify, several brain disorders, including epilepsy, Alzheimer’s and Parkinson’s diseases as well as some cancers.
In response to infection the immune system produces unique antibodies to target each illness. To make these new antibodies, cells in the immune system must intentionally damage their own genes, meaning they run the risk of becoming cancer cells. New research reveals how a proteins called Tia1 acts as a hair-trigger for DNA repair, allowing the immune system to walk the line between health and harm.
The presence of the bacterium Kingella kingae in children’s throats was strongly linked to bone and joint infection with the same bacterium, according to new research.
During major epidemics, cramped airplane cabins are fertile ground for the spread of infection, but new research suggests changing routine boarding protocols could be a key to reducing rampant transmission of disease.
By studying a worm infection, scientists have discovered how lymphatic vessels grow within lymph nodes, with major implications for cancer and inflammation.
Scientists have filled a research gap by developing a laboratory model to study ticks that transmit flaviviruses, such as Powassan virus. Powassan virus was implicated in the death of a New York man earlier this year. The unusual model involves culturing organs taken from Ixodes scapularis ticks and then infecting those organ cultures with flaviviruses.
Scientists used a novel live-cell fluorescent imaging system that allowed them for the first time to identify individual viral particles associated with HIV infection.
