By evolving!
This methicillian resistant bacteria was not always that way, but as you may know every time an antibiotic is used there are always some variations of the bacteria that are resistant. They survive, reproduce and pass this resistance on to their progeny. And the process repeats so that soon, as bacterial generations are quick, you have super resistant bacteria. This is evolution by natural selection. Change in a population of organisms over time.
What else can I help you with?
How is the structer of the cerebrum thought to relate to the evolution of human intelligence?
It isn't
How does hair growth in ears nose relate to evolution?
It really doesn't since Human Evolution is only a theory and a highly unlikely one at that.
How does paedogenisis relate to the evolution of vertebral chordates?
Evolution of chordates is based on pedogenetic theory i.e. primitive chordate ancestor evolved from echinoderm by pedogenesis .
What is septic MRSA?
Septic (sepsis) MRSA means that the MRSA bacteria has entered into the blood.
What is the MRSA colonized resident?
MRSA colonized resident means that the person is a carrier of the MRSA bacteria.
How does a unharmful staphylococcus turn into MRSA?
MRSA stands for methicilin-resistant staph aureus. MRSA is a type of staph, and a MRSA infection is a kind of staph infection.
Is MRSA a virus?
MRSA is still very rare and will not be in the air. Some studies do talk of the 'MRSA' cloud that can be around an MRSA sufferer, who is ill enough that they do not move very much. An MRSA carrier who may not be ill from the bacteria but has symptoms of respitory infection that lead them to sneeze and cough can project the the MRSA bacteria all around them.
What microbe causes MRSA?
does MRSA cause bacteria
Is mrsa serious when found in the saliva?
MRSA can be in saliva.
Does Moxifloxacin kill MRSA?
No. MRSA is resistant to Amoxicillin.
What if your spouse cheated can you get MRSA from that?
I guess you "could" get MRSA from your cheating spouse, although MRSA is not commonly spread sexually.
How has mrsa evolved from non-resistant s aureus?
Methicillin-resistant Staphylococcus aureus (MRSA) evolved from non-resistant Staphylococcus aureus through the acquisition of the mecA gene, which encodes a modified penicillin-binding protein (PBP2a) that has a low affinity for beta-lactam antibiotics. This genetic change allows MRSA to survive treatment with methicillin and other related antibiotics. Over time, MRSA strains have diversified and adapted, leading to increased virulence and resistance to multiple drug classes, making infections more challenging to treat. The evolution of MRSA highlights the impact of antibiotic use and resistance on bacterial populations.
