coli to amoxicillin; clavulanic acid is the result of hyperproduction of TEM-[beta] lactamase, production of penicillinase
resistant to inhibitors, and production of cephalosporinase , ampicillin 50% versus 40%, and tetracycline 50% versus 20%.
The oxacillin is an antibiotic of the penicillin group, and it is resistant to the staphylococcal penicillinase
. Its main indication are the infections provoked by these microorganisms in many places, usually abscesses, septicemias, pneumonias (Souza, 2011).

[2, 3] Other known mechanism of methicillin resistance is the hyperproduction of penicillinase
Methicillin was first introduced in 1959 and was used to resist the action of penicillinase
, the enzyme responsible for the resistance to penicillin.
As opposed to the penicillinase
gene, mecA does not reside on a plasmid but on the chromosome, embedded in a large mobile genetic element called Staphylococcal Chromosome Cassette mec or SCCmec [10, 11].
saprophyticus was the exception as the majority of other staphylococci are penicillinase

is a specific type of [beta]-lactamase, showing specificity for penicillins, again by hydrolysing the beta-lactam ring.
Also, Penicillin resistant strains will remain resistant to all penicillins except penicillinase
stable penicillins (including Cephalosporins, Carbapenem and Beta lactam/ Beta lactamase inhibitors).

These antibiotics are not readily affected by cephalosporinase or penicillinase
enzymes produced by certain bacteria .
