Group A Streptococcus: Two genes linked to ‘flesh-eating’ bacterial infections

By

Group A Streptococcus bacteria cause a variety of illnesses that range from mild nuisances like strep throat to life-threatening conditions including pneumonia, toxic shock syndrome and the flesh-eating...

NIST physicist Ward Johnson observes signals generated by bacteria coating quartz crystals, a novel method of sensing whether an antibiotic kills the bacteria. The new NIST technique senses mechanical fluctuations of bacterial cells and any changes induced by an antibiotic. With further development, the technique could hasten the identification of effective medical treatments in clinical settings and drug development. Image/Burrus/NIST

Rapid test may determine whether an antibiotic combats a given infection

By

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a potential new tactic for rapidly determining whether an antibiotic combats a given infection, thus hastening...

Group A streptococcus: Researchers unlock potential pathway to treat

By

Researchers at Houston Methodist have solved a 100-year-old mystery, providing them a possible key to unlock a pathway for treating diseases caused by flesh-eating bacteria. This is timely news, given...

Leprosy hijacks our immune system, turning it against itself: Researchers

By

Leprosy is an infectious disease that affects the skin and peripheral nerves and is caused by Mycobacterium leprae and, less commonly, Mycobacterium lepromatosis. According to the World Health Organization,...

Lassa fever: UTMB researchers develop treatment effective eight days after infection

By

A collaborative team of scientists, led by a group at The University of Texas Medical Branch at Galveston, have successfully protected nonhuman primates against one of the most deadly viruses in the world,...

Kingella kingae is a fastidious Gram-negative coccobacillus that colonizes the respiratory and oropharyngeal tract in children. K. kingae occasionally causes invasive disease, primarily osteomyelitis/septic arthritis in young children, bacteremia in infants, and endocarditis in school-aged children and adults Image/CDC

Kingella carriage in children’s throats strongly linked to bone and joint infection: Study

By

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 published in the Canadian...
