Coley’s Toxin is really: a mix of harmless viruses. a mix of pathogenic bacteria. a mix of random organisms taken from sick individuals. a mix of microbes from the soil.
How does having a capsule increase the virulence of a bacteria cell? A capsule gives bacteria antibiotic resistance. Bacteria with a capsule cannot be phagocytized by immune cells. The capsule speeds up asexual reproduction of the bacteria. The capsule increases bacteria motility.
What statement describes the danger of using heavy metals to control microbe growth? Group of answer choices Heavy metals promote biofilm formation in humans. Heavy metals stimulate some microbes to reproduce even more. Heavy metals can assist with virus attachment to host cells. Heavy metals are toxic to many organisms besides microbes.

What is the difference between a probiotic and prebiotic? Group of answer choices Prebiotics are natural chemicals present in food, whereas probiotics are artificial chemicals added to food to improve their nutritional value Prebiotics are living microbes that transform food, whereas probiotics are microbes grown in the lab and added to food. A prebiotic is a microbe acquired before birth, whereas a probiotic is a microbe acquired after birth A prebiotic serves as food for probiotics, which are consumable live microbes with health benefits

The bacterium Staphylococcus aureus is ___________ in shape and ______________ in arrangement. Treponema pallidum, the causative agent of syphilis is ____________ in shape. The asexual reproduction in bacteria is __________________________. Bacteria found in very cold areas are called _________________. Some bacteria can form _________________ to withstand unfavorable conditions in the environment. Bacterial cells move with the use of _________________. These bacteria can live in areas with very minimal concentration of oxygen. The cell wall of bacteria is made-up of the polysaccharide ______________________. Gram negative bacteria have ____________________ cell wall than Gram positoive bacteria. Many gram-negative bacteria belong to group ______________of Phylum Proteobacteria.
The inhibition of bacterial growth and reproduction without necessarily destroying the organisms is the result of a disinfectant a sterilant a bactericide an antiseptic
A virus broke out in a remote area. There are no infected people in my area yet. But we have lots of samples. Please explain in detail how we got a lot of samples.
For many years, scientists believed in the "Miasma Theory" which suggested that many diseases, such as cholera and the black death, were caused by pollution or bad air. Hospitals would air rooms out daily by opening windows to remove any bad air that might infect patients. When microscopes were invented, scientists could view very tiny organisms that lived in water and on surfaces all around them. Many scientists believed it was these "germs" that spread disease and not the air. Robert Koch was able to isolate microorganisms from sheep that had contracted anthrax. He grew these bacteria and then injected them in mice. The mice became sick with anthrax. REASONING: If microbes (germs) were responsible for causing anthrax, then... a) sheep and mice that were in the same area would both get sick b) sheep would get sick, but not mice c) microbes from sick sheep could make mice sick
Acyclovir, Streptomycin, polymyxin, sulfonamide, or penicillin (choose one to fill in the blank Blank is an example of an antibiotic that will destroy the cell wall and Acyclovir, Streptomycin, polymyxin, sulfonamide, or penicillin (choose one to fill in the blank) Blank antibiotic will then have an easier time getting into the pathogen to block protein synthesis, this being an example of how synergistic drugs act.
What is the best explanation for why a bacteriostatic treatment might be chosen over a bacteriocidal treatment? Bacteriostatic treatments will eliminate all bacteria while bacteriocidal treatments will only eliminate a portion of the bacteria. Bacteriostatic treatments typically have lower toxicity to the host when compared to bacteriocidal treatments. Bacteriostatic treatments will prevent all bacterial growth, while bacteriocidal treatments will permit some bacterial growth. Bacteriostatic treatments are typically more costly than bacteriocidal treatments.
