Why might a physician be likely to develop bacteria that are resistant to all antibiotics?

The bacteria may have grown in an environment where it is introduced to the antibiotics therefore making it immune to the drugs.

How does resistance develop in bacteria?
Bacteria, like all organisms, have phenotypic variations. Some bacteria are resistant to antibacterial drugs and survive the onslaught of these drugs. They then go on to have progeny ( by fission ) that they confer this resistance on so that you have a new population of resistant bacteria.
Which Biological agent susceptible to antibiotics but can develop resistance to them?
B- Bacteria
What happens to bacteria over time when exposed to antibiotics frequently?
They develop resistance to antibiotics .
How do microogarnisms avoid being attacked by antibiotics?
They don't. They develop a resistance to it. Just like people, each bacteria is slightly different even from bacteria of the same type. Some are slightly more resistant to a given drug than others. What happens is that when someone is given antibiotics and the drugs are not enough to kill all the bacteria only those that are most resistant to that drug remain. Even worse is when someone decides they feel better and stop taking their antibiotics. Then the bacteria split and/or share their genes with other bacteria and as a result that resistance is passed on to future generations.
Why are antibiotics no use when treating virus?
Virus develop a resistant coat outside the covering of their cell preventing any antibiotic from damaging them. Hence there is no effect on them.
What biological agent may be susceptible to antibiotics and can develop resistance?
Bacteria
Which biological agent may susceptible to antibiotics but can develop resistance?
bacteria
Why are some bacteria resistant to antibiotic drugs?
Bacteria can become resistant by many means. Antibiotics can affect several different parts of a bacterium such as cell wall synthesis (the penicillins affect this) or protein synthesis and several others. If for example an antibiotic affects cell wall synthesis by inhibiting an enzyme then if the bacteria mutates to overproduce that enzyme then it becomes resistant to that antibiotic at therapeutic concentrations. Or the bacteria could mutate so it does not need that exact enzyme any more and the antibiotic becomes useless. Some of the dangerous pathogens like methicillin resistant Staphylococcus aureus (MRSA) have acquired resistance to several antibiotics by selective mutation (otherwise known as evolution). Some bacteria are not so good at mutating or are less dangerous as pathogens so they cannot acquire resistance at all or as quickly.Other bacteria can produce spores which are very tough capsules which contain all the genes of a bacterial species but are not viable cells, the spores are highly resistant to antibiotics because they are very thick and do not carry out normal cellular functions so they are not affected by antibiotics. Anthrax and Clostridium dificille can form spores.Some bacteria like Listeria and in some cases Staphylococcus aureus can get inside the human cell like a virus and become resistant to the immune system and also to drugs because it is harder for drugs to get inside a human cell.
Why would a child develop ampicillin resistant bacteria?
because he wants to heheheheheheh
Scientists develop antibiotics to fight bacterial diseases Which statement correctly summarizes how antibiotics work?
They interrupt processes vital to the bacteria.
How is resistance to antibiotics shared from one bacteria to another?
Bacteria develop resistance to antibiotics through the process of natural selection. The antibiotic will kill most of the population of bacteria but not all because some of them already have the resistance. Also if the antibiotic is not utilized correctly ( according to a physicians instructions ) some of the more hardy individuals of the bacteria population will live. These bacteria breed and produce offspring that are also more resistant to antibiotics. Generations of bacteria happen much more rapidly than with people so the ability of bacteria to adapt to new environments is much more robust with respect to time.
Why might an elderly person be likely to develop cephalosporin-resistant bacteria?
because he is an expert hehehehehehe
