coli to amoxicillin; clavulanic acid is the result of hyperproduction of TEM-[beta] lactamase, production of penicillinase resistant to inhibitors, and production of cephalosporinase [10], 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).

coli, like OmpA (13,14), PhoA (15), pelB (14,16), LTB (17), npr (18), StII (19,20), DsbA (8), penicillinase (21) and natural hGH signal peptide (22).
[2, 3] Other known mechanism of methicillin resistance is the hyperproduction of penicillinase enzyme.
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 producers (13).
The penicillinase enzyme has been used in the production of the sensor.
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 [5].
