Which antibiotic does not interfere with cell wall synthesis?
β-Lactam antibiotics are a broad class of antibiotics that includes penicillin derivatives (penams), cephalosporins (cephems), monobactams, and carbapenems.
β-Lactam antibiotics are bacteriocidal and act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls.
Which antibiotics causes misreading of mRNA?
4.6 AminoglycosidesAminoglycosides are potent bactericidal antibiotics that act by inhibiting bacterial protein synthesis, thereby binding bacterial 30S or 50S ribosomal subunit, inhibiting the translocation of the peptidyl-tRNA from the A-site to the P-site, and also causing misreading of mRNA.
Which organism is most sensitive to natural penicillin?
Natural penicillins are considered the drugs of choice for several infections caused by susceptible gram positive aerobic organisms, such as Streptococcus pneumoniae, groups A, B, C and G streptococci, nonenterococcal group D streptococci, viridans group streptococci, and non-penicillinase producing staphylococcus.
Which antibiotic would be most useful for treating a salmonella infection?
Salmonella infections are commonly treated with fluoroquinolones or third-generation cephalosporins, such as ciprofloxacin and ceftriaxone.
