Antibiotics are drugs used to treat infections caused by bacteria and other microorganisms.
Methicillin-resistant Staphylococcus aureus (MRSA) infections are caused by a type of staph bacteria that has become resistant to the antibiotics used to treat ordinary staph infections.
Engineers at the University of California San Diego have developed a desktop diagnosis tool that detects the presence of harmful bacteria in a blood sample in a matter of hours instead of days.
A landmark report by the World Health Organization in 2014 observed that antibiotic resistance -- long thought to be a health threat of the future -- had finally become a serious threat to public health around the world.
Day in and day out, in our bodies, the DNA in cells is damaged for a variety of reasons, and thus intercellular DNA-repair systems are fundamental to the maintenance of life.
Researchers at the University of Southampton have developed a new 3D system to study human infection in the laboratory.
Colistin is used as the "last-resort antibiotic" for dreaded multidrug-resistant pathogens, especially in hospitals. However, gut bacteria that have become insensitive to colistin now exist -- owing to the mobile resistance gene mcr-1. In early 2016, bacteria carrying this resistance gene were detected in Germany for the first time.
With the first detailed analysis of a cellular component from a close relative of the pathogen that causes tuberculosis, Rockefeller scientists are suggesting strategies for new drugs to curb this growing health problem.
A Michigan State University researcher has developed a faster way to detect the bacteria causing patients to become sick, giving physicians a better chance at saving their lives.
No magic elixir can prevent children from developing occasional colds and viruses, but takings steps to boost their immune system can minimize their chances of catching every bug that winds its way through the daycare center or school.
An international team led by the University if Barcelona has identified a new antibacterial mechanism that protects macrophages - defense cells in the immune system- from the infection of the bacteria Salmonella enterica serovar Typhimurium, a pathogen associated with several gastrointestinal diseases.
Oral administration of a cocktail of three viruses, all of which specifically kill cholera bacteria, prevents infection and cholera-like symptoms in animal model experiments, report scientists from Tufts University School of Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts in Nature Communications on Feb. 1.
When a cell is dividing, two identical structures, called centrosomes, move to opposite sides of the cell to help separate its chromosomes into the new cells.
As human diseases become alarmingly antibiotic resistant, identification of new pharmaceuticals is critical.
The mcr-1 gene--a gene that makes bacteria resistant to colistin, an antibiotic of last resort, and that is transferrable between bacteria--has been found in a wide variety of strains of Escherichia coli in China following widespread use of colistin in agriculture.
Scientists have discovered a key 'survival gene' that prevents strains of tuberculosis (TB) from mutating into drug-resistant 'superbugs'.
A recent review of research suggests that changes to the microorganisms (microbiota) in the gastrointestinal (GI) tract may be a cause of irritable bowel syndrome (IBS).
Klebsiella bacteria cause about 10 percent of all hospital-acquired infections in the United States. K. pneumoniae sequence type 258 (ST258) is one of the Carbapenem-Resistant Enterobacteriaceae organisms labeled an urgent threat by the Centers for Disease Control and Prevention.
A new treatment for Clostridium difficile (C.diff) infections reduces recurrent infections by nearly 40%, a large study has found.
A cutting edge, portable DNA sequencing device is being brought into North Hospitals for the first time by scientists fighting against anti-microbial resistance.
Staphylococcus aureus is one of the most feared, multi-resistant pathogens. The bacterium often causes life-threatening infections, particularly in people with a weakened immune system.
