A vаriety оf mechаnisms exist fоr аntibiоtics by which they inhibit bacterial growth and ultimately destroy a bacterium. In response, bacteria have developed resistance mechanisms to counter the effects of antibiotics. Answer a-e. a. Describe how beta-lactams inhibit bacterial growth (1 pt) b. Describe the resistance mechanisms against beta-lactams (1 pt) c. Describe how vancomycin inhibits bacterial growth (1 pt) d. Describe the resistance mechanism against vancomycin (1 pt) e. Swollen joints/extremities in children can be caused by septic arthritis due to an infection with gram-positive Staphylococcus or Streptococcus – suggesting a treatment with vancomycin. However, similar disease symptoms could be due to Lyme disease caused by the gram negative Borrelia burgdorferi which will not respond to vancomycin (Mw ~ 1500) but responds to the beta-lactam amoxicillin (Mw ~ 400). Rapid analysis of synovial fluids for bacterial pathogen detection is therefore important for correct treatment. So, why is vancomycin ineffective against Borrelia although both antibiotics target the same bacterial cell function (1 pt)
