Which microorganism is the source of the antibiotic neomycin?
Neomycin is derived from the bacterium Streptomyces fradiae. It is commonly used as an antibiotic to treat bacterial infections.
Is streptomycin a bad bacteria?
Streptomycin is not a bacteria; it is an antibiotic derived from the bacterium Streptomyces griseus. Streptomycin is used to treat bacterial infections, particularly tuberculosis and certain types of bacterial meningitis.
Is bacterium a broad spectrum antibiotic?
There is no antibiotic called as bacterium. So there is no question of it's being called as broad spectrum or narrow spectrum antibiotic. Bacterium is a term related to bacteria, a type of micro-organism.
When an antibiotic binds to bacterial ribosomes how specifically does that affect the bacterium?
the antibiotic binds to bacterial ribosomes when the antibiotic is taking to kill the bacteria, as the antibiotics is taking it bind to the smaller subunit of the bacterial ribosomes ,preventing the bacterium making new protein.
What is antibiotic resistant bacterium is?
superbug.
How is antibiotic resistance observed in bacteria in light of Darwinian selection theory?
A random mutation causes one bacterium to become resistant to an antibiotic. Then all the others are killed when the antibiotic is introduced to the environment. The mutated bacterium is free to reproduce and soon many members of that species are resistant to that antibiotic.
How is the presence of antibiotic resistance used as a marker in bacterial transformation?
Antibiotics will kill off all of the bacteria that have not mutated and formed a resistance to the drug. Those that have a resistance to the antibiotics will survive and multiply into many resistant bacterium. This continuously facilitates the production of new kinds of antibiotic resistant bacteria
How is gram staining useful to health care workers?
The gram stain will stain a bacterium then a particular antibiotic might be effective against it. If the gram stain will not stain that particular bacterium, then that particular antibiotic will not be effective against it. Thus a gram negative bacterium like TB requires a different antibiotic than a gram positive bacterium. However, if several have formed a film, it may contain many types and it becomes harder to kill them. That may require a broad based antibiotic.
What is the small DNA segment in bacterium called?
The small DNA segment found in bacteria is called a plasmid. Plasmids are circular extrachromosomal DNA molecules that can replicate independently of the bacterial chromosome. They often carry genes that provide bacteria with advantages such as antibiotic resistance.
Is strep throat a viral bacterial or fungal infection?
Bacterial. Streptococcus or 'strep' is the type of bacterium.
With respect to the problem of antibiotic-resistant tuberculosis which entity evolves?
bacterium
Is bacterium made by antibiotic of bacteria?
Yes, of course! But not all the time.
