The main resistance mechanism of bacteria to penicillin is based on its own production of enzymes, the penicillinases, which degrade the penicillin before it can have effect (Daum, 2007).
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].
Penicillin may be rendered ineffective due to the presence of bacteria which produce penicillinase (Sheldon et al.
The injection is used to treat infections caused by penicillinase producing staphylococci, which have shown susceptibility to the drug.
However, a combination of a new cephalosporinase and penicillinase provides inactivation of a broad spectrum of 13-lactam antibiotics, including cephalosporins of the third and fourth generation.

Reductions were found for all classes of antibiotics other than penicillinase resistant penicillins but were largest and significant individually for phenoxymethylpenicillins (penicillin V) (7.
Our findings were in agreement with other workers (24,26) who reported that Staphylococci (both penicillinase negative and positive) were highly susceptible to meropenem.
The increase in the prevalence of both PPNG and TRNG isolates might be due to acquisition of penicillinase plasmid in the TRNG isolates as transfer of penicillinase plasmid requires the presence of conjugative plasmid (23).
