GmPcides work by targeting gram-positive bacteria. These types of bacteria can cause various drug-resistant staph infections, toxic shock syndrome, and other bacterial illnesses that can turn deadly.

A bacteria can either be Gram-negative or Gram-positive. These terms come from the Gram-staining test developed by Hans Christian Gram in 1884, which involves applying a purple stain to bacteria.

Gram-positive and gram-negative bacteria differ in the composition of their cell walls. Gram-negative bacteria have a double layer of protection, making them more difficult to kill, Muñoz said.

First, gram-negative bacteria have a thin cell wall that is about 1.5 to 10 nanometers across, whereas gram-positive bacteria have a thick cell wall measuring about 20 to 80 nanometers.
