If you expose the bacterium to the antibiotic how will the antibiotic kill it?

Answer 1

All antibiotics do is change the PH value of the blood. Some bacteria will thrive in a alkaline environment, while others adore acidic. Depending on where the infection is, lungs, or bladder, will determine what type of antibiotic, alkaline or acidic. Once you change the PH of the blood, the bacteria cannot multiply. That is why some people succumb to chest infections, while the person sitting opposite does not, two different environments, alkaline, acidic.

Answer 2

do you have any specific antibiotic in mind? because that depends on the kind of antibiotic that you are using because there are so many antibiotics now a days with different mode of actions. for instance, there is your penicillins which kills bacteria by inhibiting formation of cell wall of some bacteria, there are your protein inhibiting antibiotics, which is further subdivided into 30s and 50s protein inhibitors, which includes the common tetracycline, erythromycin.there are some that works in the bacterial DNA, such as your fquinolones. these are just some...

Answer 3

there's many ways to skin a cat.
1. some antibiotics interfere with growth: bacteria can't make the proteins it needs, either by inhibiting the polymerase or ribosomes (like streptomycin)
2. assembly: penicillin inhibits synthesis of peptidoglycan - the cell wall - bacteria can't maintain osmotic pressure and rupture
3. DNA replication: gyrase (only found in bacteria) - are another target. It can't unwind its DNA, so it can't make copies, or transcribe mRNA to make proteins

these are just some of the ways I can think of off the top of my head

Answer 4

And to add to what was already said depending on the class of antibiotic it will: inhibit cell-wall synthesis during multiplication ultimately causing cell-wall destruction, promote osmotic instability, inhibit protein synthesis, alter the cytoplasmic membrane, inhibit formaion of dyhydrofolate acid form PABA, decrease bacterial folic acid sybthesis, be bactericidal, be bacteriostatic, or inhibit DNA synthesis.
