drugs that inhibit the cel wall synthesis |
there is no cell wall in the human cells so these drugs are selectively toxic. Problems with these dru gs are allergic reactions and development drug resistant strains |
|
|
the bacterial cell wall is made of chains of |
NAM, NAG, glycans cross-linked by peptide bridges |
|
|
Three important reasons PCN is not effective against all bacteria |
1) The outer membrane of gram-negative bacteria blocks entrance of PCN
2) must be young, actively growing cells
3) Some bacteria may produce penicillinases aka beta-lactamases that destroy natural penicillin by breaking bond in the beta-lactam ring
|
|
|
relatively broad-spectrum, resistant to most penicillinases, causes fewer allergic reations |
Cephalosporin |
|
|
is used to treat skin infections caused by Staphylococcus and Steptococcus and is the main ingredient in Neosporin |
Bacitracin |
|
|
is used for MRSA or in patients allegic to penicillin |
