In the Gram-positive bacteria, the cell wall is thick (15-80 nanometers), consisting of several layers of peptidoglycan complexed with molecules called teichoic acids. In the Gram-negative bacteria, the cell wall is relatively thin (10 nanometers) and is composed of a single layer of peptidoglycan surrounded by a membranous structure called the outer membrane.

Gram staining of bacterial cells is neither an accurate nor elaborate technique, but nevertheless it is practically useful to distinguish two big domains of eubacteria species: Gram-positive bacteria that include most of the Firmicutes, and Gram-negative bacteria that include the rest.

The cell wall envelope of gram-positive bacteria is a macromolecular, exoskeletal organelle that is assembled and turned over at designated sites. The cell wall also functions as a surface organelle that allows gram-positive pathogens to interact with their environment, in particular the tissues of the infected host. All of these functions require that surface proteins and enzymes be properly.

In PRTK’s OASIS most skin and skin structure infections were caused by gram-positive bacteria, such as Staphylococcus aureus. IV-to-oral or oral-only omadacycline both resulted in high.
