The first bacteria to show resistance to methicillin, was staphylococci. It was demonstrated in Landon in 1964, probably. This was taken place due to composition of the staphylococci, probably. They live in grape like clusters. So the inner bacteria does not enough quantity of antibiotic. This favors the development of resistant bacteria. Staphylococci has shown resistance to many antibiotics since then. The most dreaded multiple drug resistant bacteria was found in India in 2009. It was resistant to almost all the antibiotics. Here in India general practice is dominated by unqualified doctors. The fee charged by these quacks is very less. People are looking after cheap doctors, specially in rural area and in slums of the cities.The government has no political will to stop the menace. These quacks always write one or two antibiotics for even the viral fevers and malaria also. The problem patient goes to specialist doctors. Who is compelled to use the higher antibiotics. These things favored the development of the bacteria, which are resistant to all the antibiotics.
What else can I help you with?
Why do plasmids contain a gene for antibiotic resistance?
Plasmids contain antibiotic resistance genes because these genes provide a survival advantage to the bacteria in the presence of antibiotics. Bacteria can pick up plasmids with antibiotic resistance genes through horizontal gene transfer, allowing them to survive in environments with antibiotic exposure. This is a common mechanism for bacteria to acquire resistance traits and poses a challenge for antibiotic treatment.
What is the example of a microevolution?
An example of microevolution is the development of antibiotic resistance in bacteria due to natural selection. Over time, bacteria that are resistant to antibiotics survive and reproduce, leading to a population of bacteria that is predominantly resistant to that antibiotic.
How does a population of bacteria resistant to antibiotics?
A population of bacteria can become resistant to antibiotics through genetic mutations that confer resistance traits. These mutations can arise spontaneously or be acquired through gene transfer from other resistant bacteria. Over time, the selective pressure exerted by antibiotic use allows the resistant bacteria to survive and multiply, leading to the spread of resistance within the population.
What type of scientist studies how bacteria are affected by antibiotics?
A microbiologist or medical scientist would study how bacteria are affected by antibiotics. They can investigate how bacteria develop resistance to antibiotics and explore new ways to combat antibiotic resistance.
How does antibiotic resistance work and what are the mechanisms behind it?
Antibiotic resistance happens when bacteria change in a way that makes antibiotics less effective against them. This can occur through mechanisms like mutations in bacterial DNA, acquiring resistance genes from other bacteria, or developing ways to pump out or break down antibiotics. These changes allow the bacteria to survive and multiply even when exposed to antibiotics, making infections harder to treat.
How is antibiotic resistance an adaptation?
The trait giving bacteria antibiotic resistance has become common, giving bacteria with the trait a selective advantage.
When bacteria are not affected by antibiotics they have?
They have resistance to the antibiotic.
Who benefits from a mutation that causes antibiotic resistance in bacteria?
The bacteria benefits.
Antibiotic in gene cloning?
If antibiotic resistance is added to the gene being cloned, antibiotics can be used to isolate the transformed bacteria (ones with the gene being cloned) by killing off all non-transformed bacteria, that don't have the antibiotic resistance. There is a chance that the non-transformed bacteria can mutate to develop antibiotic resistance.
How does plasmid allow for antibiotic resistance?
A plasmid (conjugative plasmid) that has a resistance gene on it, can transfer itself to another bacterial cell (called conjugation) or assist in the transfer of a non-conjugative plasmid that has a resistance gene to another cell (called mobilization). Whichever way it happens, once the plasmid is transfered to the new cell, this cell too may show signs of resistance to the particular antibiotic. This is one of the ways of the speard of resistance amongst bacteria
Why do plasmids contain a gene for antibiotic resistance?
Plasmids contain antibiotic resistance genes because these genes provide a survival advantage to the bacteria in the presence of antibiotics. Bacteria can pick up plasmids with antibiotic resistance genes through horizontal gene transfer, allowing them to survive in environments with antibiotic exposure. This is a common mechanism for bacteria to acquire resistance traits and poses a challenge for antibiotic treatment.
A mutation that causes antibiotic resistance in bacteria is a what mutation?
Missense mutation Nonsense mutation Frameshift insertion Frameshift deletion All may cause antibiotic resistance in bacteria
What is a word meaning a bacteria has adapted to antibiotics?
Resistant or resistance is when a bacteria has adapted to an antibiotic.
What is an extra loop of DNA that contains antibiotic resistance what gene?
An extra loop of DNA that carries antibiotic resistance genes is called a plasmid. These genes can provide bacteria with the ability to survive exposure to antibiotics.
Which type of adaptation develops quickly in bacteria that are antibiotic resistant?
Horizontal gene transfer is a type of adaptation that allows bacteria to acquire antibiotic resistance genes quickly from other bacteria. This process involves the transfer of genetic material between different bacteria, enabling the rapid spread of antibiotic resistance within a population.
What type of adaptation develops quickly in bacteria that are antibiotic resistant?
Horizontal gene transfer is a type of adaptation that can quickly lead to antibiotic resistance in bacteria. This process involves the transfer of genetic material between different bacteria, allowing for the spread of antibiotic resistance genes.
What contributes to the spread of antibiotic resistance among pathogenic bacteria?
Directional Selection
