Bacteria and Antibiotics Lab Report

The goal of this lab report is to answer the following two questions: Is there a difference in the effectiveness of the three antibiotics azithromycin, ceftriaxone, ciprofloxacin against Neisseria meningitidis, Haemophilus influenzae and Streptococcus pneumoniae? How does cell wall structure affect susceptibility to antibiotics (those used in your sensitivity testing)? The experimental design used to answer these questions is performing a disc-diffusion antibiotic susceptibility test and gram staining. The results of both experiments are: Streptococcus pneumoniae is gram positive, Neisseria meningitidis is gram negative, and Haemophilus influenzae is gram negative. I have attached a bar graph that shows the results of the disc-diffusion antibiotic susceptibility test which are the average diameters of the zone of inhibitions for each bacteria with each antibiotic. I have also attached the peer-reviewed papers needed for 7) “CSLI zone size interpretative chart” and “BD antimicrobial susceptibility test.”

1) Give background information on all bacteria and antibiotics you did your experiment on(mentioned above)
2) Write about what is already known about them in the research literature. 6 journal papers minimum – primary scientific articles (4 at least) and secondary scientific articles (review papers). Find more recent papers, published within the last 10– 20 years.
3) What is left unanswered and what is the significance of your experiment?
4) What are your goals (objectives)? The aim of your study should be clearly stated immediately after discussing the basic references.
5) Mention your experimental design.
6) State the hypothesis and your prediction(s) in the last paragraph. Don’t forget to cite throughout the text – (author, year), for example: (Jensen, 2006) or (Stevens and Bonvecchio, 2001) or (Zhou et al., 2010).
Written in present tense, and past tense if mentioning previously found data.
