What does the term fitness mean in antibiotic resistance?
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.
Why might an elderly person be likely to develop cephalosporin-resistant bacteria?
Elderly individuals often have weakened immune systems due to aging, making them more susceptible to infections. They may have a history of frequent antibiotic use, which can lead to the development of antibiotic-resistant strains of bacteria. Additionally, elderly individuals may reside in long-term care facilities where there is a higher prevalence of resistant bacteria.
Which term refers to the ecological niche of many bacteria and fungi in an ecosystem?
decomposer
Which term refers to water that is drinkable without being treated for bacteria mineral deposits and poisonous contaminations?
Distilled water potable A+
What is the differences between zone of inhibition and zone of exhibition?
Zone of inhibition :-It is the area on an agar plate where growth of a control organism is prevented by an antibiotic usually placed on the agar surface. If the test organism is susceptable to the antibiotic, it will not grow where the antibioitic is. Zone of exhibition:-
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 daptomycin mean?
The term 'Daptomycin' refers to a form of antibiotic that is used to treat life threatening infections. It is a compound that naturally occurs in the soil and has been found extremely effective in treating a variety of infections that are caused by multi-resistant bacteria.
What is evolution and can you provide an example to explain the term?
Evolution is the process by which living organisms change and adapt over time through natural selection. An example of evolution is the development of antibiotic resistance in bacteria. When exposed to antibiotics, only the bacteria with genetic mutations that make them resistant survive and reproduce, leading to a population of bacteria that is mostly resistant to the antibiotic.
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.

What term means the medication of death bacteria?
antibiotic
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 the medical term meaning drug that inhibits or kills bacteria?
antibiotic
What would happen if you didn't finish a course of antibiotics?
If you stop taking your antibiotic before you complete the course any surviving bacteria developes an immunity to that antibiotic. You must then take a different, usually stronger antibiotic to kill the infection. Once that happens that particular antibiotic usually will not work for any bacterial infection you may get.
What the supperbug infection called?
The term "superbug" refers to bacteria that are resistant to multiple antibiotics, making them difficult to treat. Examples include MRSA (Methicillin-resistant Staphylococcus aureus) and CRE (Carbapenem-resistant Enterobacteriaceae).
