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 full the opposite. The pivotal think all over called Operation Sea atomiser was conducted in the early 1950s. The coalesce States Army was testing how nose 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 by and by burst and the supposed harmless Serratia marcescens was released over the city. at bottom 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 average pathogen. A pathogen is an agent that causes ailment or infection. Pathogens can unremarkably be identified by their ability to metabolize lactose. Fermenters of lactose argon non-pathogenic and non-fermenters argon pathogenic. Anti-pathogenic agents, called antibiotics, atomic number 18 used to fight these diseases and infections. Antibiotics go away by targeting excess diseased cells and not well full of life cells. each antibiotic is usually capable to fight one quality of organism. Two examples argon of antibiotics ar Tetracycline and Streptomycin.         The ubiquitous Serratia marcescens is a member of the family Enterobactieriaceae.

Members of this family be known to be nigh of the some pathogenic and earthy organisms encountered in microbiological studies. These bacterium atomic number 18 gram negative, rod shaped, and are most commonly seen causing intestinal infections. Although usually name in the intestine, they are too found in most natural habitats. few other sicknesses caused by these organisms are: Meningitis, bacillar 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 sort out among the species are...
