exactly what it says. it is a mechanism that confers drug resistance to microbes. exactly what it says. it is a mechanism that confers drug resistance to microbes.
Plasmids are often transferred to other bacterial cells via the sex pilus. This mechanism is a major cause in the spread of antibiotic resistance genes.
The resistance of an organism to disease is known as immunity. This defense mechanism helps protect the body from harmful pathogens such as bacteria, viruses, and parasites.
Streptomyces erythreus naturally produces macrolide antibiotics. It must have a protection mechanism so its protein does not attack itself. This mechanism is most commonly methylation of the 23S rRNA target, and an efflux pump for macrolides. The mechanism of resistance in MLS Staphylococci is the same as Strep erythreus. It is more likely the bacteria shared a simple gene that codes for these resistance mechanisms rather than staph naturally becoming resistant for no competitive reason.
Without an air resistance mechanism, no.
It is when a certain bacteria resists a drug such as antibiotics
Which mechanism explains the phenomenon
The bacteria benefits.
A random mutation in one bacteria can result in this. think of a huge population of bacteria. billions of bacteria. and only 5 or so have the resistance by a random chance (random mutation). the antiobiotics will kill all of bacteria, except for the 5 with the resistance. Then, only those 5 will reproduce. since they reproduce asexually, this resistance will be passed on to all of the daughter. Then, all of sudden, there are a lot of bacteria around that are resistant to the antibiotic... it can also occur by conjugation, which is when a bacteria inserts its DNA into another bacteria. this can result in the second bacteria having the resistance too. this is a very basic description of the process.
The trait giving bacteria antibiotic resistance has become common, giving bacteria with the trait a selective advantage.
Mutations of Bacteria from Virus Sensitivity to Virus Resistance was created in 1943.
genetic changes in plants, antibiotic resistance in bacteria, and pesticide resistance in insects.
