Persistent Pathogens
"Pathogens can remain alive and active even on dry surfaces, and be picked up by hands, feet, etc. A large percentage of seemingly normal asymptomatic individuals can be carriers of pathogens. MRSA is a good example of this. Perhaps 15-30% of so-called normal individuals are carriers of MRSA; that is why the problem is so widespread."

This colorized scanning electron micrograph (SEM) depicted a flagellated Vibrio vulnificus bacterium; Mag. 26367x.
Vibrio vulnificus is a bacterium in the same family as those that cause cholera. It normally lives in warm seawater and is part of a group of vibrios that are called "halophilic" because they require salt. V. vulnificus can cause disease in those who eat contaminated seafood or have an open wound that is exposed to contaminated seawater. Among healthy people, ingestion of V. vulnificus can cause vomiting, diarrhea, and abdominal pain. In immunocompromised persons, particularly those with chronic liver disease, V. vulnificus can infect the bloodstream, causing a severe and life-threatening illness characterized by fever and chills, decreased blood pressure (septic shock), and blistering skin lesions. V. vulnificus bloodstream infections are fatal about 50% of the time.
