Performance of Malaria Rapid Diagnostics Tests Evaluated Post-Treatment

The performance of different malaria rapid diagnostic tests (RDT) may be influenced by transmission intensity and by the length of time each test requires to become negative after treatment and patient’s recovery. More...

Rapid Blood Test Can Rule Out Serious Childhood Infections

The care for acutely ill children has traditionally been a primary care responsibility, but increasing numbers are being seen in secondary care, but a simple decision rule and a finger prick to test blood, general practitioners can now detect serious infections in children very quickly. More...

Image: A diagram of the newly discovered mechanism of action of the bacterial superantigen toxins: Superantigens bind to both B7-2 and CD28, the major costimulatory receptors expressed on human immune cells. This binding enhances B7-2/CD28 receptor engagement, thereby inducing a powerful immune signal that evokes a harmful inflammatory storm (Photo courtesy of Professor Raymond Kaempfer).

Groundbreaking Immune Approach Targets Humans Instead of Bacteria

Staphylococcal and streptococcal infections affect millions of individuals each year and they are a leading cause of sepsis and account for many cases of pneumonia and post-surgical infections. More...

Fungus Identified As Key Factor in Crohn’s Disease

Researchers have for the first time identified a fungus, Candida tropicalis, as a key factor in the development of Crohn’s disease in humans. They have also linked a new bacterium to the bacteria previously associated with Crohn’s. The groundbreaking findings could facilitate development of new treatments and ultimately cures for the debilitating inflammatory bowel disease More...

Rapid Adaptation of Aspergillus Presents Doctors with Dilemma

Aspergillus fumigatus causes a range of diseases in human beings, some of which are characterized by fungal persistence and the fungus can persist by adapting to the human lung environment through physiological and genomic changes. More...
