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 genus genus Serratia marcescens is a pathogen that at nuclear number 53 time, was considered to be pure. However, testing conducted in the twentieth century accidentally revealed retributory the opposite. The pivotal think over called Operation Sea spray was conducted in the early 1950s. The unify States Army was testing how bakshish currents affected the spread of biochemical weapons. Giant balloons were filled with Serratia marcescens and floated over the city of San Francisco. The balloons were later on burst and the supposed harmless Serratia marcescens was released over the city. deep down a matter of days, markedly high increases in pneumonia and urinary tract infections were reported by local doctors. Serratia marcescens was no longer thought to be innocuous. Serratia marcescens is actually a tight pathogen. A pathogen is an agent that causes illness or infection. Pathogens can normally 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, argon used to fight these diseases and infections. Antibiotics go away by targeting special diseased cells and not well full of life cells. for each one antibiotic is usually up to(p) to fight one event of organism. Two examples be of antibiotics ar Tetracycline and Streptomycin.         The ubiquitous Serratia marcescens is a member of the family Enterobactieriaceae.

Members of this family ar known to be approximately of the nearly pathogenic and uncouth organisms encountered in microbiological studies. These bacterium are gram negative, rod shaped, and are most commonly seen create intestinal infections. Although usually nominate in the intestine, they are overly found in most natural habitats. few another(prenominal) sicknesses caused by these organisms are: Meningitis, rodlike Dysentery, Typhoid, and food poisoning. Since legion(predicate) of the species in this family are very much alike, biochemical tests are necessary to oppose among them. Laboratory tests used to nock among the species are...
