Gram negative antibiotics pdf

In the fight against pathogenic bacteria, Gram-negative bacteria such as Escherichia coli and Pseudomonas aeruginosa are particularly challenging foes. These microbes don’t respond to many common antibiotics, and no new drug active against Gram-negative bacteria has been approved in nearly a half-century. Gram positive coverage: 1. Penicillins (ampicillin, amoxicillin) penicillinase resistant (Dicloxacillin, Oxacillin) * 2. Cephalosporins (1st and 2nd generation)* 3. Macrolides (Erythromycin, Clarithromycin, Azithromycin)* 4. Quinolones (gatifloxacin, moxifloxacin, and less so levofloxacin)* 5. Vancomycin* (MRSA. 1. Less antibiotic activity than Penicillin G against Gram positive bacteria 2. More activity than Pen G against Gram negative bacteria 3. Can be used on patients who are allergic to penicillin 4. Side chain acetoxy group is hot point for metabolic inactivation C. Cephaloridine 1.

Side chain acetoxy group is hot point for metabolic inactivation C. Cephaloridine 1. Gram-negative organisms comprise a large portion of the patho-gens responsible for lower respiratory tract infections, especially those that are nosocomially acquired, and the rate of antibiotic resistance among these organisms continues to rise. Systemically administered antibiotics used to treat these infections often haveCited by: PeptidoglycanLayer. GramPositiveBacteria: Thepeptidoglycanlayeristhickandmultilayered.

In the fight against pathogenic bacteria, Gram-negative bacteria such as Escherichia coli and Pseudomonas aeruginosa are particularly challenging foes. These microbes don’t respond to many common antibiotics, and no new drug active against Gram-negative bacteria has been approved in nearly a half-century. Antimicrobial resistance is rapidly increasing among gram-negative bacteria. Gram-negative bacteria are common causes of community- and nosocomial-acquired infections. Common mechanisms of resistance in gram-negative pathogens include altered target sites, b-lactamase production, decreased antibiotic penetration, and efflux pumps.The antibiotic resistance patterns of gram-negative bacteria of different genera also correlated well, perhapsindicating that bacteria which share.
