BACTERICIDAL VS BACTERIOSTATIC

bactericidal vs bacteriostatic

Prescriptions recommended by the doctors are mandatory when it comes to taking of antibiotic drugs purchased from over-the-counter pharmaceutical outlets. The condition of the patient should be examined first before prescribing an antibiotic. Not all antibiotics can therapeutically treat all kinds of illness, it is still depends on the type of bacteria that penetrates through the body. Speaking of these antibiotics, what are the differences between bactericidal and bacteriostatic?

Bactericidal Bacteriostatic
Activities Kill microbial cells Prevent the growth  of microbial cells
Microorganisms When bactericidal agents are used microorganisms are not viable when bacteriostatic agents are used microorganisms remain viable
Infections Doesn’t allow the immune system to deal with infections Allow the immune system to deal with infections
Doses If the doses of bactericidal agents are low those may act as bacteriostatic agents If the doses of bacteriostatic agents are high those may act as bactericidal agents
Denote Minimum Bactericidal Concentration is the minimum concentration of drug needed to kill bacteria Minimum Inhibitory Concentration is the minimum concentration of drug need to inhibit bacterial growth

Bactericidal used to eliminate the microorganisms or to kill a specific strain of bacteria that inhabited the body. The popularly used medicine for this type of antibiotic agent includes penicillin, vancomycin and monobactams. The term used to describe the minimum concentration for this kind of drug is referred to as “minimum bactericidal concentration” or MBC. If the prescribed dosage of bactericidal is low, it responds as a bacteriostatic.

In contrast with the aforementioned, bacteriostatic used to reduce the reproduction and growth of the microorganisms by means of interfering the cellular composition of the bacteria. Unlike bactericidal, this drug works together with the immune system of the body to fight with the microbial cells. Most antibiotic agents of this type include tetracycline, lincosamidesand  chloramphenicol.  The term used in pertaining to the minimum concentration of this kind of drug is called “minimum inhibitory concentration” or MIC. If the prescribed dosage of bacteriostatic is high, it reacts as a bactericidal.
