Researchers at the London School of Hygiene & Tropical Medicine are trying to find out if the antibodies we all have to fight parasites might be attacking harmless triggers as well. Could the “hygiene” hypothesis, that we now have fewer parasites to fight so the immune system attacks allergens as well, be the reason there is such a large increase in allergies? 

Protein analysis suggests that antibodies that evolved to fight parasites might be turning their focus to otherwise harmless agents.

New Treatment May Help Children with Peanut Allergy

Could desensitization be the holy grail of treating children with peanut allergies? Pediatric allergist Dr. Billy Tao of Flinders Medical Centre in South Australia is showing promising results with a two-step desensitization process that first involves boiling peanuts for an extended length of time to make them less allergenic. If the child shows no signs of an allergic reaction, roasted peanuts are given to increase their tolerance. But don’t try it at home! Read about this exciting research here.

Scientists have warned for decades that the overuse of antibiotics leads to the development of drug-resistant bacteria, making it harder to fight infectious disease. The Centers for Disease Control and Prevention estimates that drug resistant bacteria cause 23,000 deaths and two million illnesses each year.
