Introduction Although bacteria is microscopic in size‚ it is largely important in the healthcare field‚ environmental work‚ food preparation‚ as well as many other industries. In particular‚ it is essential that healthcare workers be able to identify the species of bacteria invading a human reservoir in order to prescribe the correct antibiotic that will kill that species. For the purpose of bacteria identification‚ numerous tests have been devised to find out the exact species in question. However

into classes helps in identifying the bacterial species and hence they are classified as gram positive bacteria and gram negative bacteria based upon their staining techniques. Penicillin is the oldest and the best known antibiotic. Basically‚ it is an antibiotic compound derived from the moulds Penicillium notatum and Penicillin chrysogenum and is active in opposition to gram positive bacteria and few gram negative bacteria. Penicillin turns out to have two rings fused together; one being the β-lactam

Tularemia (Rabbit Fever‚ Deer-fly Fever) Tularemia is an infective disease caused by the gram negative bacteria Francisella tularensi (F. tularensis)‚ which is found in habitats limited to the Northern division. (misc.medscape.com)The disease got the name description in 1911 of a plague like illness found in ground squirrels in Tulare County‚ California‚ by Dr. Edward Francis. This bacteria is usually found in rabbits‚ and can also found in other small animals like rodents‚ muskrats‚ beavers‚ squirrels

walls of bacteria‚ a Gram stain determines what kind of bacterium the cell is. The Gram stain works by creating a purple dye that either attaches or fails to attach to the peptidoglycan either found or not found on the cell wall of the cell. Gram-positive bacteria are cells that have a large amount of peptidoglycan in their cell wall‚ and those that are Gram-negative have an extra cell wall that does not allow the stain to set on the cell wall (Vidyasagar). In addition to staining the cell‚ the identification

Chapter 1 Cell Theory- in the 18th century‚ two scientists came up with the cell theory. Schleiden and Schwen. 3 corollaries of the cell theory: -all cells are alike in chemical composition -all cells store and process information in the same way -all cells arise from other cell through cell division 5 types of different Microscopes 1.
