Parasites as the treatment

Helminth infection promotes colonization resistance via type 2 immunity

Parasitic worms affect gut microbes
Improved hygiene practices in high-income countries may come with an increased risk of developing inflammatory bowel disease (IBD) or other similar disorders. Ramanan et al. show that intestinal helminth infection, caused by parasitic worms, protects IBD-susceptible mice from developing the disease.
The infection increases specific protective species and limits other inflammatory members of the microbiota.
People from helminth-endemic regions harbored a similar protective microbiota, and their deworming led to an increase in inflammatory Bacteroidales species, similar to what the authors observed in the mice. Thus, a changing microbial environment may shape susceptibility to inflammatory disease.

Bite Me

Volunteers Who Say ‘Bite Me’ Are Helping To Win The War Vs. Mosquitoes

The mosquitoes are even outsmarting the bed nets by learning to dine at an earlier hour.

“Instead of biting in the middle of the night now, when people are sleeping, they’re biting in the evening when they’re sitting outside by the fire,” Clark says. “So the bed nets are becoming less and less effective.”
