In 1950, the American Navy conducted a secret experiment called “Operation Seaspray” to study wind currents that might carry biological weapons.

They filled balloons with. Marcescens and is released over San Francisco shortly thereafter experienced doctors in this area a dramatic increase in pneumonia and urinary tract infections. We read about it in a treatise known history of the USA. Today we know that Serratia have more hospitals tend to colonize the respiratory and urinary tract than the gastrointestinal tract, because that is easily acquire resistance to antibiotics.
