SERRATIA MARCESCENS

Serratia marcescens bacteria on a cracker. This is a common microbe living in the soil, water, on plants, and in animals. Because of its bright red color and because it may grow on bread and crackers stored in a damp place, it has contributed to miracles, simulating the blood of Jesus Christ on communion wafers. In a study called Operation Sea-Spray, the US Army filled balloons with S. marcescens and burst them over San Francisco in 1951 and 1952. A severe incidence of pneumonia and urinary tract infections followed shortly afterwards, and the bacterium was not considered harmless anymore. Enhanced SEM. Image width: 8.5 micrometers. Magnification: 11,765x if the image is printed 10 cm wide.
