Bacteria isolated from patients infected with stealth-adapted viruses can produce complex solid and thread-like structures similar to the alternative cellular energy pigments (ACE pigments) seen in cultures of stealth-adapted virus infected patients. Bacteria replication of stealth-adapted viruses can explain why certain patients diagnosed as having delusional parasitosis insist that the particles that they believe are parasitic, increase in number even when outside of the body. Bacterial production of ACE pigments may also be contributing to the ACE pigments that can be isolated from the hair, sweat, and urine of such patients. The term viteria has been applied to stealth-adapted viruses that have acquired bacterial sequences. Viteria infected bacteria clearly pose an important public health problem and may lead to a wider dissemination of stealth-adapted viruses.
