In the context of antibiotic resistance, "fitness" refers to the ability of bacteria to survive and reproduce in the presence of antibiotics compared to non-resistant strains. Resistant bacteria may have mutations or genetic traits that confer survival advantages, allowing them to thrive even when exposed to antibiotics. However, these traits can sometimes come with fitness costs, such as slower growth rates or reduced competitiveness in the absence of antibiotics. Ultimately, the balance between resistance and fitness influences the prevalence and spread of antibiotic-resistant strains in bacterial populations.

What is fitness cost in microbiology?
In microbiology, fitness cost refers to the reduced reproductive success or survival of an organism due to the acquisition of certain traits, such as antibiotic resistance or metabolic adaptations. These traits may confer short-term advantages in specific environments but can compromise overall fitness in other conditions. For example, a bacterium that develops resistance to an antibiotic may have slower growth rates in the absence of that drug. Understanding fitness costs is crucial in predicting the dynamics of microbial populations and the evolution of resistance.
What does the term OHM mean?
It is a unit of measurement to measure the resistance an object possesses when electricity flows through it.
What term is used to describe how well organisms function in an enviorment?
Fitness
What term is the best used to describe how well organism functions in its environment?
Fitness
Are all diffusible pigments antibiotic in action?
Not by definition, and maybe yes and maybe no. Antibiotic is a term generally applied to something created by a micro-organism that inhibits the growth of other micro-organisms. In general, diffusible pigments are not antibiotic by this definition. But as regards whether or not such a pigment will inhibit micro-organic growth, some will and some won't.
What is the Medical term meaning superbug infection?
Antibiotic resistance is a type of drug resistance where a microorganism is able to survive exposure to an antibiotic.
What is a sentence using the term antibiotic resistance?
The doctor prescribed antibiotics to cure her case of strep throat.
How do antibiotic resistant bacteria come about?
This term is misleading. The antibiotic "selects" bacteria that are not affected by it. If a person will grow bacteria on a petri dish and add an antibiotic to it, some bacteria may live and grow. This is actually a form of natural selection. The ones that will grow are resistance to the antibiotic. They have some way of not being affected. If a person takes a colony from the plate that has this resistance and grows it on another plate and add the antibiotic, all on the plate will be resistant.
What does the term physical fitness mean?
1 met = resting energy expenditure
What does the physical fitness term MET mean?
1 met = resting energy expenditure
What is an example of a long term fitness goal?
Achieving life-long fitness is a long-term fitness goal.
When reading nurses notes what does the term ABT continued mean?
When you see a nurses notes that say ABT continued it means that the patients antibiotic therapy is continued. The ABT stands for antibiotic therapy.
What can occur after long-term antibiotic therapy?
after long-term antibiotic therapy, patients can become more susceptible to yeast infections
Which is the term for replicating circular pieces of DNA that often carry antibiotic-resistant genes?
The term for replicating circular pieces of DNA that often carry antibiotic-resistant genes is "plasmids." Plasmids are small, independent DNA molecules found in bacteria and some eukaryotes, and they can replicate independently of chromosomal DNA. They often play a crucial role in horizontal gene transfer, allowing bacteria to share traits such as antibiotic resistance.
Which scientist coined the term antibiotic?
The term "antibiotic" was coined by Sir Alexander Fleming, the scientist who discovered penicillin in 1928.
What is an example of a long-term fitness goal?
Achieving life-long fitness is a long-term fitness goal.
What term means the medication of death bacteria?
antibiotic
