With respect to the problem of antibiotic-resistant tuberculosis which entity evolves?
bacterium
How is antibiotic resistance observed in bacteria in light of Darwinian selection theory?
A random mutation causes one bacterium to become resistant to an antibiotic. Then all the others are killed when the antibiotic is introduced to the environment. The mutated bacterium is free to reproduce and soon many members of that species are resistant to that antibiotic.
How might individual bacterium become resistant to an antibiotic?
it inherited the allele that made it resistant
What are some problems that arise when a bacteria become resistant to an antibiotic?
The antibiotic resistance may be transferred to a virulent pathogenic bacterium. Then we will not be able to cure the infection.
How would you isolate an antibiotic-resistant bacterium?
you can use low concentration of first line antibiotic to the media where will growth antibiotica.perobably most of bacteria will die but some of them will survive.This bacteria are resistant to antibiotics.Its important to inoculate a large amount of bacteria.
What would best describe the means by which an individual bacterium would have antibiotic resistance?
it inherited the allele that made it resisnt.
How is the presence of antibiotic resistance used as a marker in bacterial transformation?
Antibiotics will kill off all of the bacteria that have not mutated and formed a resistance to the drug. Those that have a resistance to the antibiotics will survive and multiply into many resistant bacterium. This continuously facilitates the production of new kinds of antibiotic resistant bacteria
Is bacterium a broad spectrum antibiotic?
There is no antibiotic called as bacterium. So there is no question of it's being called as broad spectrum or narrow spectrum antibiotic. Bacterium is a term related to bacteria, a type of micro-organism.
What does resistant or susceptible mean?
These terms refer to antibiotic sensitivities; antibiotic resistant organisms versus antibiotic susceptible organisms.
What is antibiotic resistant bacteria?
Also known as "superbugs", antibiotic resistant bacteria have evolved to a point that our usual antibiotics won't kill them. VRE and MRSA are common forms of antibiotic resistant bacteria.
The term antibiotic resistant refers to bacteria that?
survive the presence of an antibiotic
Why has there been a large increase of antibiotic resistant strains of bacteria?
Overuse of traditional antibiotics has caused a selection of those bacteria that are resistant to the antibiotic.
