What are some examples of bacteria that can form an endospore? How long is it generally viable? Suggest three ways in which food might become contaminated by harmful bacteria. Which portions of a bacterial cell aid the ability of a bacterium to cause infections?
Some bacteria under stress form a dormant stage called an endospore. They are produced during unfavorable environmental conditions. They grow to vegetative form when the conditions become favorable. They have four distinct structural components; (i) core, containing nucleoid and condensed cytoplasm, (ii...
Vegetative bacteria are generally much more easily inactivated than are bacterial endospores. This is primarily because the sensitive areas of bacteria are easily contacted by chemosterilizing agents. The spore, however, has a more complex structure than the vegetative bacterial cell. Its sensitive ...
Endospore Staining is a technique used in bacteriology toidentify the presence of endospores in a bacterial sample, which can be useful for classifying bacteria. What diseases are diagnosed using the Gram stain procedure? Gram-positive infections includemethicillin-resistant Staphylococcus aureus (MRSA),...
Compared to other flagella structures, peritrichous flagella project from all directions of the cell which allows the bacteria to move rapidly in any direction. Endospores, which may be observed distending from one end of the bacterial cell may be oval or spherical in shape. ...
Lesions begin as small draining wounds that eventually form nodules; then ulcerate, leaving large areas of exposed, raw tissue. The bacteria can spread throughout the body and cause more severe disease and death. Can I get sporotrichosis?Yes. ...
In the late 1970s, scientists discovered that microorganisms once considered bacteria were actually a different life form:archaea. These organisms live in severe conditions where bacteria and animals are not found. For example, ocean-dwelling archaea live near vents where temperatures exceed 212 degrees...
Catalase is a four-part enzyme, or a tetramer. Four monomers wrap around each other to form a dumbbell-shaped enzyme. Each monomer has four domains, or parts -- like body parts that do different things. The second domain is the one that contains the heme group. The third domain is the...
What type of spores are produced when the fungal component of a lichen reproduces sexually?Spores:Spores are the unit of sexual or asexual reproduction that form part of the life cycles of algae, fungi, bacteria, and various plants. They are adapted for survival a...
