Many antibiotics work by targeting specific components or processes essential for bacterial growth, such as cell wall synthesis, protein synthesis, or DNA replication. By interfering with these critical functions, antibiotics can disrupt the bacteria's ability to replicate and survive, ultimately leading to their death.

How does dehydration help control bacteria?
Dehydration can help control bacterial growth by removing moisture, which is essential for the survival and reproduction of many bacteria. Lack of water can inhibit the metabolic processes of bacteria and prevent them from thriving in an environment.
Differences between bacteriostatic and bacteriolytic agent?
Two possible ones: the bactericidal will kill off many more than just the one you want to target (killing off very helpful ones) or the bactericidal is rather toxic to the host (you). If you use the bacteriostatic, the body will have more time to mount an effective counter attack and win.
What are the 3 growth patterns of bacteria?
The three growth patterns of bacteria are exponential growth, stationary phase, and death phase. Exponential growth is when bacteria multiply rapidly, stationary phase is when growth rate equals death rate, and death phase is when bacteria start dying off due to nutrient depletion or waste accumulation.
Do bacteria require water for their survival and growth?
Yes, bacteria require water for their survival and growth. Water is essential for many biological processes within bacteria, such as nutrient uptake and metabolism. Without water, bacteria would not be able to function properly and would eventually die.
Why might a gram-negative infection be harder to treat than gram-positive infection?
In short, it's because they have a membrane around their cell wall that both increases their toxicity, and makes them more resistant to antibiotics. It makes them more resistant because many antibiotics, such as penicillin, work by destroying the cell walls of bacteria. Because they have an extra membrane around their cell walls, gram negative bacteria have extra protection against the antibiotics.
are Antibiotics are useful for limiting the growth of most pathogenic bacteria?
no, many bacteria have become resistant due to improper use of antibiotics.
What are quinolones?
Fluoroquinolones are medicines that kill bacteria or prevent their growth. (Medical Encyclopedia)For the source and more detailed information concerning your request, click on the related links section (Answers.com) indicated below this answer box.
How do antibiotics prevent bacteria and viruses?
There are several different mechanisms by which antibiotics kill or prevent the proliferation of bacteria.For instance, penicillins and cephalosporins bind to specific sites in the bacterial cell wall and prevent the bacterium from making new cell wall, so the wall they have breaks down and the cell dies.Others, like aminoglycosides, prevent the production of proteins in bacteria, so they cannot reproduce or grow.Some, like fluoroquinolones bind to a protein that prevents the bacterium from being able to duplicate its DNA.For as many different antibiotics, there are different mechanisms of action. Some kill the bacteria directly, and are called bactericidal and others prevent the bacteria from spreading and are called bacteriostatic. Bacteriostatic antibiotics slow the growth of the bacteria and allow the immune system to kill it off.
What is a drug that fights bacterial infection?
antibiotics ans sulfa drugs prevent bacteria from multiplying :D
What phase is most susceptible to antibiotics?
It is the exponential phase. Many antibiotic such as the Streptogramin family work on the ribosome and indeed the DNA and RNA polymerases. These are most active when the bacteria are dividing and so it causes more harm as it were. Also in Mycobacterium, when dividing it does not have such a thick cell wall, and so it is easier for the antibiotics to penatrate that is true, also known as the Log phase and is when an organism is most sensative to antibiotics like penicillin-
What kind of bacteria would grow on a water fountain?
There are many kinds of bacteria that can grow on a water fountain, such as Pseudomonas and Coliform. However, there are things you can do to prevent bacteria growth. Filter systems, chemical coatings and ultra-violet light systems are available on many modern water fountains to inhibit bacteria growth.
What did penicillin do?
it cured many diseases
A type of bacteria that produces many antibiotics?
e. coli
What is genus streptomyces?
Streptomyces is a genus of bacteria that are known for producing various bioactive secondary metabolites, including antibiotics and antifungals. These bacteria are commonly found in soil and have a filamentous growth pattern similar to fungi. Streptomyces species play a critical role in the production of many important antibiotics used in medicine.
Give several ways in which the development of antibiotics-resistant pathogen can be slowed or prevented?
Give fewer antibiotics to humans and animals. Ensure that when antibiotics are given, they are used in sufficiently high dosages and for long enough to kill as many bacteria as possible.
Why do fungi produce antibiotics that inhibit bacterial growth?
Fungi and bacteria are in direct competition with each other when it comes to decomposing dead matter. If a fungus would like to be the dominant decomposer; it will find a way to kill its neighbor bacteria.
Can bacteria prevent diseases in humans?
The so called commensals are basically the most useful bacteria for you. You have very large number of bacteria present in your gut. They prevent damage to your body by harmful bacteria. They help you in digestion and provide you, few, very important vitamins. Some times they are killed by use of broad spectrum antibiotics and then the opportunistic bacteria take over causing the problematic condition called as pseudo-membranous enterocolitis. Untreated this condition can kill the patient by way of dehydration. As you know the antibiotics. They are produced by microorganisms only and are used very commonly to prevent so many diseases.
