How does lysozyme work to break down bacterial cell walls?
Lysozyme works by targeting and breaking down the bonds in the peptidoglycan layer of bacterial cell walls, weakening the structure and causing the cell to burst.
How do aminoglycosides work?
Aminoglycosides work by binding to the bacterial ribosome, disrupting protein synthesis and causing mistranslation of mRNA. This leads to the production of faulty proteins, ultimately inhibiting bacterial growth and promoting cell death.
What is the medical significance of Bacterial spores?
Bacterial spores are far more resistant to disinfectants than non-spore forming bacteria. As a result, bacterial spores are more virulent and therefore more capable of causing disease since they can survive most methods that kill 'normal' bacteria...
How can you kill bacterial cells by centrifugation?
Bacterial cells cannot be lysed (or killed) through centrifugation alone. Although repeated centrifugation and resuspending will kill many bacterial cells as a result of shear stress on the cell membrane
What will happen if a bacterial cell is placed in distilled water with lysozyme?
The bacterial cell will undergo osmotic lysis due to the hypotonic environment created by the distilled water, causing water to enter the cell and potentially burst it. The presence of lysozyme will further damage the bacterial cell by breaking down its cell wall, making it more susceptible to lysis.
Adding nucleotides to a gene causing a frameshift to occur is what?
an AN insertion
What is a bacteria causing disease in the lungs?
Bacterial pneumonia would be one.
IS An example of a carcinogen ultraviolet light?
Yes, ultraviolet light is an example of a carcinogen. Carcinogens are cancer-causing substances, and exposure to UV light can lead to skin cancer.
Which bacterial organism is responsible for rheumatic fever?
Streptococcus pyogenes, also known as Group A Streptococcus, is the bacterial organism responsible for causing rheumatic fever.
Main disease causing organisms?
Viruses, Bacterial, Parasites, Fungal, Worms and Protozoas which one is the smallest?
What is streptcoccus?
It is a bacterial cell species that are round shapes, can't move, infection-causing, and are found in the body.
What energy is ultraviolet rays?
Ultraviolet rays possess electromagnetic energy and are part of the electromagnetic spectrum. They have higher energy levels than visible light, making them capable of causing sunburn and skin damage when exposed to them for extended periods.
Can Amoxillian Cure Bacterial Vaginosis?
Amoxicillin is not typically used to treat bacterial vaginosis. Bacterial vaginosis is usually treated with antibiotics specifically targeted towards the bacteria causing the infection, such as metronidazole or clindamycin. It is important to consult a healthcare provider for proper diagnosis and treatment.
What is the medical terminology combining form meaning causing death?
-cidal is the medical terminology combining form meaning causing death as in bacteriocidal (causing bacterial death) or virucidal (causing viral death).
How do fluorescent bulbs glow?
Fluorescent bulbs contain mercury vapor that emits ultraviolet light when electricity excites it. The ultraviolet light then hits a phosphor coating inside the bulb, causing it to glow and produce visible light.
How does a fluorescent lamp operate?
A fluorescent lamp operates by sending electrical current through a gas-filled tube containing mercury vapor. This current excites the mercury atoms, causing them to emit ultraviolet light. The ultraviolet light then interacts with the phosphor coating on the inside of the tube, causing it to glow and emit visible light.
What is the energy pathway for fluorescent light?
In a fluorescent light bulb, electricity passes through a gas (such as mercury vapor) causing it to emit ultraviolet light. The ultraviolet light then strikes a phosphor coating on the inside of the bulb, causing it to emit visible light. This conversion process is more energy-efficient compared to incandescent bulbs.
