New Fronts on the War Against Harmful Bacteria

I find bacteria interesting. They can be our enemies or our friends. The Los Angeles Times article titled, New ways to fight bacteria, provides a brief overview on our war against harmful bacteria. Bacteria are constantly evolving resistance to our arsenal of antibiotics. We constantly develop new antibiotics while bacteria constantly evolve ways around them. To gain the upper hand in this frustrating war, scientists are currently looking at:

1. Employing viruses harmful to bacteria that are not infectious to humans. Bacterial viruses are known as phages.
2. Utilizing good bacteria, aka probiotics, to colonize areas where harmful bacteria attack, diminishing the effects of the harmful bacteria.
3. Learning what chemicals in frogs' skin protect frogs from harmful bacteria. Frogs live in warm moist climates and have evolved effective ways to protect against harmful bacteria.
4. Brains of cock roaches and locusts. This is the weirdest one. However, it turns out, a scientific experiment found insect tissue can kill 90% of MRSA (bacterium methicillin-resistant Staphylococcus aureus). One lab found the antimicrobials are concentrated in these two bugs' brains.
5. Drugs that mimic antimicrobial defense mechanisms employed by our immune system.
6. Blocking the harmful substances produced by bacteria to give our immune system time to mount a defense.
