How the Immune System Combats Superinfection

New research from Yale University shows how the immune system combats superinfections, revealing a biological basis for new vaccines against sexually transmitted diseases and possibly HIV. The immune system is great at making sure infections such as the herpes virus do not repeatedly infect a person, a condition known as a superinfection. Yet how the […]

Researchers Discover New Tick Borne Infection

Similar to Lyme disease, a new tick-borne infection known as Borrelia miyamotoi has been discovered in people in the United States. A new tick-borne infection that shares many similarities with Lyme disease has been discovered in 18 patients in southern New England and neighboring New York by researchers at the Yale Schools of Public Health […]

Scientists have developed fully sterile fabrics by using enzymes that adhere antimicrobial particles with textiles. These fabrics could help eliminate infectious bacteria from medical textiles. Researchers at the Unversitat Politècnica de Catalunya BarcelonaTech (UPC) in Spain were able to use an enzymatic pre-treatment, which was combined by the deposition of nanoparticles and biopolymers under ultrasonic […]

According to a new study, more than 40% of tuberculosis infections that are resistant to front-line antibiotic treatments have also become resistant to some common backup drugs. Efforts to control tuberculosis are being hindered by the emergence of multi drug-resistant (MDR) strains, making it harder to combat. Researchers published their findings in the journal The […]

Pathogens that cause plague or cholera use miniature syringes to introduce molecular agents into their host cell, disabling the immune defense of the infected cell. Scientists have now revealed the structure of this miniature syringe at atomic resolution, which may lead to the development of drugs and strategies to prevent this process. The plague, bacterial […]

The flu can be lethal in some patients, but benign in others. The reason that this is the way that flu infections work might be the cause of a protein, which might be mutated in patients who are more easily affected by the flu than others. The new study was published in the journal Nature, […]

It’s been reported that the common fruit fly, Drosophila melanogaster, drinks alcohol to kill the wasps that have hatched inside of its body, which would otherwise eat it alive. Drosophila melanogaster gets the alcohol from eating yeasts that grow on rotting fruit that can contain up to 6% alcohol. The flies have even developed a […]

Neurocysticercosis is caused when people ingest pork that has gone bad and is the root cause of several types of seizures. In a new study that was published in the journal PLoS Pathogens, scientists at the Baylor College of Medicine have discovered that Substance P is the culprit of neurocysticerosis. Neurocysticercosis is the main reason […]

In Indian hospitals, over 50% of bacterial infections are now resistant to commonly used antibiotics. Surveys have shown that many widespread pathogens in India are also resistant to powerful, broad-spectrum antibiotics. In 2010, a team of scientists analyzed bacterial infections in New Delhi and found that 24% could resist the hospital’s last resort intravenous antibiotics, […]

A new study published in Science shows that prion diseases, such as bovine spongiform encephalopathy (BSE) and variant Creutzfeldt-Jakob disease (vCJD), are able to jump species a lot easier than previously thought, because they can replicate in the spleen without necessarily affecting the brain. Thousands of silent carriers of prion diseases in the UK might […]
