Bacterial infection takes hold in the body when a pathogenic microorganism delivers toxins to healthy cells. One way bacteria accomplish this is by releasing vesicles, which act as tiny envelopes transporting toxins and other virulence factors to host cells. These toxins allow the bacteria to "m...

Bacteria that cause tuberculosis trick immune cells meant to destroy them into hiding and feeding them instead. This is the result of a study led by researchers from NYU Langone Medical Center and published online April 18 in Nature Immunology. Read More

Breast milk provides an inexpensive, nutrient-filled source of food for babies. Because of this, the American Academy of Pediatrics and the WHO recommend new mothers to exclusively breast feed their babies for the first six months of life, and continue up to two years (supplemented with other fo...

April 15, 2016, Barcelona, Spain: A new study presented today demonstrates a potential link between treatment of long-term oral nucleos(t)ide analogues and an increased risk of colorectal (p=0.029) and cervical (p=0.049) cancer in patients with chronic Hepatitis B virus (HBV). The study results ... Read More
April 15, 2016, Barcelona, Spain: A new study, presented today at The International Liver Congress™ 2016 in Barcelona Spain, demonstrates that the use of antiviral therapy for patients in the immune tolerant phase of Hepatitis B (HBV) prolongs overall survival and reduces the risk of the most co...

Not long after the appearance of an outbreak of viral disease, first scientists, and then newswriters, blame it all on mutation of the virus. It happened during the Ebolavirus outbreak in West Africa, and now it’s happening with Zika virus.
The latest example is by parasitologist Peter Hotez,... Read More
For the first time, US disease experts have agreed that the mosquito-borne Zika virus does indeed cause babies to be born with abnormally small heads — a condition known as microcephaly. Until now, the two conditions were linked — but experts didn’t know for sure if Zika caused the brain-damaged... Read More
Researchers at the University of California, Berkeley, who have discovered more than 1,000 new types of bacteria and Archaea over the past 15 years lurking in Earth's nooks and crannies, have dramatically rejiggered the tree to account for these microscopic new life forms. Read More
As reported in a new study in the the journal Proceedings of Royal Society B: Biological Sciences, scientists have taken a step toward identifying the genetic mechanisms that makes some lowland leopard frogs in Arizona resistant to Batrachochrytrium dendrobatridis (Bd) infections that cause the ...

Lung ultrasound has been shown to be highly effective and safe for diagnosing pneumonia in children and a potential substitute for chest X-ray, according to a study conducted at the Icahn School of Medicine at Mount Sinai. Results are currently published in the medical journal Chest. Read More
Researchers at University of California, San Diego School of Medicine have received a five-year, $9.5-million award from the National Institute of Allergy and Infectious Diseases at the National Institutes of Health (NIH) to establish an interdisciplinary center to define the systems biology of ...

Like us, bacteria have their own microbial attackers, in the form of bacteria-specific viruses called bacteriophage, or phage. These phage come in a variety of flavors but can be broadly categorized into virulent, which immediately begin to replicate and lyse (burst) the infected cell quickly, a... Read More
A combination of artemisinin and another drug (artemisinin combination therapy, ACT) is currently the best malaria treatment recommended by the World Health Organization. In early 2015, artemisinin-resistant malaria was confirmed in five countries in Southeast Asia: Cambodia, Laos, Myanmar, Thai... Read More
The TWiPtastic trio solves the case of the Surfer from Switzerland, and reveal how taste-chemosensory tuft cells in the gut regulate immune responses to parasites.
A new study suggests that Neanderthals across Europe may well have been infected with diseases carried out of Africa by waves of anatomically modern humans, or Homo sapiens. As both were species of hominin, it would have been easier for pathogens to jump populations, say researchers. This might ... Read More
