General description
Chemical structure: β-lactam
Application
Cloxacillin is a semisynthetic antibiotic in the same class as penicillin. Cloxacillin is used against staphylococci that produce β-lactamase. It is used to study the role of pH in antibiotic effectiveness and how oxgall, acid, and hydrogen peroxide stress effects the susceptibility of Bifidobacteria.
Biochem/physiol Actions
Cloxacillin interferes with the last stage of bacterial cell wall synthesis by binding to penicillin-binding proteins. This inhibits the necessary cross-linking and leads to autolysis of the bacteria by autolysins.
Other Notes
Keep container tightly closed in a dry and well-ventilated place.

Early studies showed that methicillin-resistant Staphylococcus aureus (MRSA) strains are susceptible to beta-lactams when they are exposed to pH < or = 5.5 in broth. Because S. aureus survives in the phagolysosomes of macrophages, where the pH may be acidic

The effects of acid, oxgall, and H(2)O(2) on susceptibilities to antibiotics and nisin were examined for 13 strains of bifidobacteria. Susceptibilities to ampicillin, cloxacillin, penicillin, vancomycin, kanamycin, neomycin, paramomycin, streptomycin, chloramphenicol, erythromycin, tetracycline, and nisin A were assayed by a
