SERRATIA MARCESCENS by Carter Stanley is a background research paper for a science fair project based on the virus Serratis Marcescens and its antibiotics Tetracycline and Streptomycin.

SERRATIA MARCESCENS Serratia marcescens is a pathogen that at atomic cast 53 time, was considered to be harmless. However, testing conducted in the 20th ampere-second accidentally revealed just the opposite. The pivotal think over called doing Sea Spray was conducted in the early 1950s. The unify States array was testing how wind currents affected the spread of biochemical weapons. giant star balloons were filled with Serratia marcescens and floated over the city of San Francisco. The balloons were after fl atomic number 18 up and the supposed harmless Serratia marcescens was released over the city. within a matter of days, markedly high increases in pneumonia and urinary footpath infections were reported by local doctors. Serratia marcescens was no daylong thought to be innocuous. Serratia marcescens is actually a miserly pathogen. A pathogen is an agent that causes disease or infection. Pathogens can usually be identified by their ability to metabolize milk sugar. Fermenters of lactose argon non-pathogenic and non-fermenters argon pathogenic. Anti-pathogenic agents, called antibiotics, ar used to fight these diseases and infections. Antibiotics go away by targeting special diseased cells and not sanguine full of life cells. Each antibiotic is usually adequate to fight one type of organism. Two examples are of antibiotics are Tetracycline and Streptomycin.         The ubiquitous Serratia marcescens is a member of the family Enterobactieriaceae.

Members of this family are known to be some of the to the highest degree pathogenic and rough-cut organisms encountered in microbiological studies. These bacterium are gram negative, ro d shaped, and are most commonly seen causin! g intestinal infections. Although usually shew in the intestine, they are also found in most natural habitats. few other sicknesses caused by these organisms are: Meningitis, bacilliform Dysentery, Typhoid, and food poisoning. Since legion(predicate) of the species in this family are very much alike, biochemical tests are necessary to say among them. Laboratory tests used to differentiate among the species are...
