Describe the effects of the various antibiotic drugs you used. Were they all equally effective at controlling bacterial growth?
Kipish [7]

Answer:

Basically, most   antibiotic drugs  are not  effective in controlling bacterial growth. The potency of any antibiotic drugs is a measure of the magnitude of  diameter of the  bacterial growth . <u>This is because the diameter   is the measurement of the bacterial growth around the antibiotic drugs used to control it multiplication, and therefore a  measure  of how effective  it  can controls the population</u> Thus a small diameter around the antibiotic agent is a proof that it suppressed the growth effectively and can effectively be used to control  the bacteria, While  a large diameter is an indication of low effectiveness of the drug.

Based on this analogy, penicillin with wide usage for control  of bacteria growth  with  diameter of 3mm, is the most effective antibiotic drugs.However, Erythromycin which is also widely used control growth with diameter of 5mm  or 6mm depending on   type of bacterial.

Therefore, the least 3mm  diameter presented by penicillin is an indication that , antibiotic drugs  are not effective enough, and further research need to be done to control growth of bacteria and therefore its   pathogenic  effects.
