Staphylococcus aureus is a spherical bacterium (coccus) which on microscopic examination appears in pairs, short chains, or bunched, grape-like clusters. These organisms are Gram-positive. Some strains are capable of producing a highly heat-stable protein toxin that causes illness in humans.
Researchers investigating the effects of an organic compound on drug-resistant bacteria found how it can impede and destroy a germ that causes significant illness or even death in some situations.
During heavy rains, Hawaii's streams, rivers, and nearshore waters change on microscopic levels. Bacteria in these aquatic systems increase, and some of these bacteria can be harmful to human health.
Osaka Metropolitan University scientists have developed a simple, rapid method to simultaneously identify multiple food poisoning bacteria, based on color differences in the scattered light by nanometer-scaled organic metal nanohybrid structures (NHs) that bind via antibodies to those bacteria.
The use of less bleach and lower temperatures over washing machine cycles is promoted as a result of shifting societal attitudes toward the environment.
In hospitals, the Staphylococcus aureus bacteria can be transported from the skin or nasal cavity into open wounds and, possibly, the bloodstream, posing a fatal hazard. Staph infections killed over 20,000 Americans in 2017, according to the Centers for Disease Control and Prevention.
Scientists have revealed how antibiotics can regress certain fast-growing bacteria. The research was published in the journal eLife on June 8th, 2022.
Infectious-bacteria-killing molecular machines have been persuaded to reconsider their goal.
Researchers at Emory University have uncovered a mechanism for skin cell death that might lead to novel therapies for “flesh-eating” infections, alopecia, hives, and possibly even melanoma, the deadliest type of skin cancer.
Antibiotic-resistant hospital pathogens are not to be underestimated as a health risk. A research team has now introduced a new approach for treating multiple-drug resistant Staphylococcus in the journal Angewandte Chemie.
A study team developed an early-stage therapy that sabotages the pump and restores antibiotic efficiency by disclosing the structure of a protein needed by bacteria to pump out antibiotics.
Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial infection that has become resistant to most of the antibiotics used to treat regular staph infections.
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.
Cutibacterium acnes, a bacteria that is known to cause acne, is also widely spread on people with healthy skin.
Scientists have developed the first “living medicine” to treat antibiotic-resistant bacteria thriving on medical implants’ surfaces.
Researchers at the Institute of Organic Chemistry and Biochemistry of the CAS (IOCB Prague) and the Technical University of Liberec in collaboration with researchers from the Institute of Microbiology of the CAS, the Department of Burns Medicine of the Third Faculty of Medicine at Charles University (Czech Republic), and P. J. Šafárik University in Košice (Slovakia) have developed a novel antibacterial material combining nonwoven nanotextile and unique compounds with antibacterial properties.
A new Cornell study has found the antimicrobial properties of certain stem cell proteins could offer a potential treatment to reduce infection in skin wounds.
Similar to how a spider traps its prey, the cells of the human immune system cooperate to trap and “eat” bacteria.
Only 21 percent of patients with severe pneumonia caused by SARS-CoV-2 (the virus that causes COVID-19) have a documented bacterial superinfection at the time of intubation, resulting in potential overuse of antibiotics, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
Bacterial infections associated with medical implants place a major burden on healthcare and cause great suffering to patients across the world.
A new study has discovered a novel tactic used by the bacterium Staphylococcus aureus to resist the immune response, boosting hopes that a vaccine to prevent lethal MRSA infections is closer than previously thought.
