SNAP provides a model for ensuring a right to food

Alleviating food insecurity is often seen as one of the fundamental roles a country should fulfill. The Supplemental Nutrition Assistance Program (SNAP) is effective in addressing the right to food in the US, and that the program can serve as an example for countries that struggle to provide food for all citizens.

Engineered viruses could fight drug resistance

Biological engineers can program bacteriophages to kill different strains of E. coli by making mutations in the protein that the viruses use to bind to host cells. These engineered phages are less likely to provoke resistance in bacteria, and could help to overcome antibiotic resistance.

Protozoans and pathogens make for an infectious mix

The new observation that strains of V. cholerae can be expelled into the environment after being ingested by protozoa, and that these bacteria are then primed for colonization and infection in humans, could help explain why cholera is so persistent in aquatic environments. The disease-causing bacteria are protected in the protozoan gut and ejected into the environment in membrane-bound expelled food vacuoles (EFVs).

How fungus-farming ants could help solve our antibiotic resistance problem

For the last 60 million years, fungus-growing ants have farmed fungi for food. In their cultivation of those fungi, they've successfully relied on bacteria-produced antimicrobial ingredients to protect their crops from other species of parasitic fungi. Now, researchers say they are looking to these ants to find new ways to stop or slow the evolution of antibiotic resistance that now presents a threat to modern medicine.

Salmonella causing bloodstream infections in central Africa resistant to nearly all drugs

The first extensively drug-resistant (XDR) strains of Salmonella Typhimurium, a pathogen which is responsible for millions of bloodstream infections per year in sub-Saharan Africa, have been identified in the Democratic Republic of Congo (DRC). Drug-resistance has increased in successive groups of S. Typhimurium over time. These new strains are resistant to all but one of the commonly available drugs in the DRC, with one sample showing reduced susceptibility to this final antibiotic.
