Question

Why is it that some bacteria is sensitive to antibiotic? Like what is happening? How does antibiotic stop them from growing?

Answer 1

Antibiotic sensitivity is the resistance of bacteria towards antibiotics.susceptibility can vary even within a species, to determine that antibiotic susceptibility testing(AST) is usually carried out to determine which antibiotic will be most successful in treating a bacterial infection in vivo.

some disease-causing bacteria can become resistant to antibiotics that are meant to kill them. once the bacteria withstand antibiotic survive and proliferate. this leads to the emergence of antibiotic-resistant strains.if a bacterial strain is resistant to several different antibiotics, it becomes a multidrug-resistant(MDR) microbe.When there are virtually no antibiotics available to treat an infected patient, it is said to be pan-resistant.

bacteria can be drug resistant in two ways; natural- the genes having resistance are already present in the bacterial chromosome or can be acquired through mutation or by antibiotic resistance genes from other microbes.

antibacterial action

an antibiotic therapy based on identifying the etiological agents( bacteria) and its relevant antibiotic sensitivity.The effectiveness of individual antibiotics varies with the location of infection access to the site of infection, and the ability of the bacteria to inactivate antibiotic. Some kill bacteria (bacteriocidal), while others prevent the growth (bacteriostatic).

bacteriostatic antibiotics limit the growth of bacteria by interfering with bacterial protein production, DNA replication or other aspects of bacterial cellular metabolism.
