1950        A secret Army experiment spread the Serratia marcescens bacteria onto San Francisco from a mine laying
ship on the bay for 6 days. The bacteria was thought to be harmless, but the germs sent 11 people to hospitals and
killed one person, Edward J. Nevin, from a heart infection. In 1977 Senate subcommittee hearings the Army revealed
that it had staged the mock biological attack.

/Ser·ra·tia/ (se-ra´she-ah) a genus of bacteria (tribe Serratieae) made up of gram-negative rods which produce a red
pigment. For the most part, they are free-living saprophytes, but they cause a variety of infections in
immunocompromised patients.

Serratia genus were once known as harmless organisms that produced a characteristic red pigment. Today, Serratia
marcescens is considered a harmful human pathogen which has been known to cause urinary tract infections, wound
infections, and pneumonia. Serratia bacteria also have many antibiotic resistance properties which may become
important if the incidence of Serratia infections dramatically increases
