This study presents evidence to propose that some human infections may derive Independent of contamination by invading pathogens.


Diverse data suggest multiple pathways Independent of contamination may generate human infections. For instance, the first microorganisms that emerged from lifeless organic matter 3.6 billion years ago indicated transformation of lifeless organic matter to micro organisms. Viral infections do correspondent to a lifeless protein particle in a cell of a complex multi- cellular organism reproducing and spreading infections to other complex multi- cellular organisms.


Some microbes -such as pseudomonas aeruginosa with a larger genome and greater functional complexity than common bacteria -may evolve from human flora as observed in mammalian decomposition in sterile soil. For, decomposer species are not foreign Invaders from the environment and they represent evolution of common microorganisms during mammalian decomposition. Human cells may produce microorganisms consistent with a proven genetic link between humans cells and the Christensenellaceae (a family in the phylum Firmicutes). Human stem cells which are capable to differentiate to epithelial cells and cancer and have the essentials to produce microbes are the most likely candidates to produce microorganisms.


What may be almost certain and not experimentally validated is the possibility that infections have multiple pathways of origin independent of contamination. Most nosocomial and opportunistic infections may be endogenous. Our knowledge may demolish the dogma of contamination by foreign microbes as the exclusive source of infections and pave novel avenues to prevent and treat diverse infections.
