Bacteria are winning the war

One interesting piece of this puzzle is that one of the body's own antibiotics (well, technically it's an anti-microbial peptide) is cathelicidin [1], and it is regulated by vitamin D. Anywhere from 1/3 to 2/3 of Americans are deficient in vitamin D, depending on what cutoff you use to determine deficiency.

In other words, doctors may want to ease up on prescribing antibiotics until they have checked a patient's vitamin D and taken care of that problem. Some of the infections will likely go away after the body has enough fuel to fight back.

Glad to see phage therapy mentioned. It is time to begin investigating it again. While most of the world was focused on antibiotics, the Soviets were researching phage therapy. Much of that work fell with the Wall.
