Intracellular bacterial penetration and growth

“Ce qui embellit le désert, c’est qu’il cache un puits quelque part.”

Antoine de Saint-Exupéry, (1900- 1944), French aviator and writer.

Half a century ago specialists considered that only viruses but not bacteria needed the cellular components of human organism for their proliferation. 

Despite this fact, for many decades bacterial intracellular penetration has been well known.

Recently interest has been attracted to this phenomenon, and it appears that this is by no way a minor fact in the development of disease.

Virulence and persistence depend largely on this fact.

Hence, viral and bacterial infection are in multiple cases not simply coexistent but appear as supporting each other.

On the other hand, some evidence points to the fact that exposition of our skin to sun rays prevents the intracellular penetration and growth of pathogens (Mycoplasma pneumoniae, Ureaplasma, the Mycobacteria, – and in similarity probably the Helicobacter pylori, and Staphylococcus aureus…).

Viruses appear to open tiny pores in cell walls, thus permitting bacterial penetration.

A higher basal metabolic rate (BMR), as for instance in children fights this event.

Sun rays act positively at increasing our BMR.
