Beta lactam antibiotics were prescribed in the majority of the patients as compared to other class of antibiotics this points towards the sensitivity of microorganism towards the beta lactam but, on the contrary, there should be vigilance regarding indiscriminate and excessive prescribing to prevent emergence of resistance and patient cost. Sulfonamide antibiotics (sulfa drugs) sulfa drugs are synthetic antimicrobial agents that contain the sulfonamide group german bacteriologist and pathologist gerhard domagk was awarded the 1939 nobel prize for physiology or medicine for discovering the antibacterial effects of prontosil red, a dye which contained the active component.

Beta-lactamases of staphylococcus can be inducible by use of beta-lactam antibiotics, meaning that after exposure to a beta-lactam agent, the organism can greatly increase beta-lactamase production the inducible production generally ceases after the beta-lactam is removed ( 172 . The beta-lactam antibiotics for their extensive scale of actions are preferred most among antimicrobial factors the penicillins and cephalosporins are the two categories of this β – lactam antibodies that are extraordinarily less toxic to organisms(1) at present ,the β-lactam groups of.
By 1961, however, methicillin resistance had appeared, and then a ‘steady evolution of beta-lactamases (enzymes that detoxify the beta-lactam antibiotics) by point mutation under the selective pressure of successive introductions of new beta-lactamase resistant penicillins, cephalosporins, carbapenems and monobactams’ (davies, 2006: 289. Serious allergies to penicillins or beta-lactam antimicrobials serious infections caused by susceptible organisms resistant to penicillins (mrsa, mrse) surgical prophylaxis for major procedures involving implantation of prostheses in institutions with a high rate of mrsa or mrse.

Like other beta lactam antibiotics, penicillin works by inhibiting a peptid that links on the cell wall of a bacteria, which weakens the bacteria cell and causes it to die due to osmotic pressure the reason penicillin is so much more effective with gram-positive bacteria is this very action gram-negative bacteria do not lose their cell walls.
Like penicillin, they have a beta-lactam ring, but beta-lactamases that destroy penicillin don't work against cephalosporin however, there are other beta-lactamases that do destroy cephalosporin.
