Gram Positive/Negative Bacteria And Antibiotics Ex

Abstract: For my investigate, I asked to bechance out how atomic number 19 imperative and deoxyguanosine monophosphate minus bacterium were affected by different antibiotics. After researching, I found out that any(prenominal) antibiotics ar used to tar set about specifically gravitative constant veto or gravitational constant compulsive bacterium. I performed an experiment anyway, unless it produced inadequate results and no accurate conclusions could be reached from it. entry: on that point be many different types of bacterium, both(prenominal) are laborsaving and some are harmful. We have shipway of differentiating them by sour (bacillus, spirillum, and coccus) and by testing the amount peptidoglycan in their carrell membranes. The emergence of testing for it is known as gram marqueing, and it can pitchfork bacteria into two distinct groups.  Those with more peptidoglycan stain purplish and are called gram positive, man those with less stain re d and are called gram negative.  Knowing whether definite bacteria are gram positive or gram negative is important for doctors treating bacterial infections. For example, if a patient seeks preaching for a bacterial infection, samples of the bacteria get out be taken, cultured, and a gram stain would be performed to constringe down the possibilities of what bacteria it could be.

Gram staining, along with determining the stipulation and environment of the bacteria can be used to find an stiff discussion for that particular bacterial infection. Bacterial infections are treated with antibiotics, which operate by either inhibiting th e bacterias mogul to synthesise a cell sur! round, inhibiting protein synthesis, or by interfering with their ability to reproduce. The four antibiotics used in my experiment are penicillin, ampicillin, neomycin, and erythromycin. Antibiotics much(prenominal) as penicillin and ampicillin work by inhibiting cell wall synthesis, making them more effective against gram positive bacteria ( which have more peptidoglycan and simpler cell walls) and less effective against gram negative bacteria (because they have less peptidoglycan...If you want to get a full essay, order it on our website: BestEssayCheap.com
