The human gut is home to 100 trillion bacteria, which, for millions of years, have co-evolved with both the digestive and immune systems.[more]

Avian influenza A viruses continue to cause disease outbreaks in humans, and extrapulmonary infection is characteristic. In vitro studies demonstrate the activity of oseltamivir against avian viruses of the H5, H7 and H9 subtypes.[more]

Rilpivirine, the non-nucleoside reverse transcriptase inhibitor in development by Tibotec, a Johnson & Johnson company, has proved to be as effective as efavirenz in two phase III trials.[more]

Salmonella, found to cause infections especially in African HIV positive populations, has been shown to be due to an excess in antibodies and not an immune system deficiency as previously speculated.[more]

HAMLET (Human Alpha-lactalbumin Made LEthal to Tumour cells) a tumoricidal complex of partially unfolded α-lactalbumin (HLA) and oleic acid was discovered by chance when researchers from University of Gothenburg were studying the antibacterial properties of breast milk.[more]

A group of researchers from Washington DC have conducted a study that shows that morphine may be neuroprotective in a subset of people infected with HIV[more]

Important advances in the fight against cancer have come about as researchers have shown that viruses and cancers interact in ways that were previously unknown. A new study led by UNC scientists shows that the commonly used cancer drug cyclophosphamide can activate a viral infection that, paradoxically, can help anti-viral medications eradicate virus-associated cancer. Researchers enrolled 21 patients aged 5-15 years with a confirmed diagnosis of Epstein Barr Virus (EBV)-related Burkitts ...[more]
