What is the importance of structural staining?
Structural Staining allows you to check for certain structures on bacteria. This is important because certain structures on a bacteria can be antigenic or act as an endotoxin. An example of this is flagella can often cause an immune response, even if the cell is already dead.
What structures do bacteria have xy?
Bacterial cells, like plant cells, are surrounded by a cell wall. However, bacterial cell walls are made up of polysaccharide chains linked to amino acids, while plant cell walls are made up of cellulose, which contains no amino acids. Many bacteria secrete a slimy capsule around the outside of the cell wall. The capsule provides additional protection for the cell. Many of the bacteria that cause diseases in animals are surrounded by a capsule. The capsule prevents the white blood cells and antibodies from destroying the invading bacterium. Inside the capsule and the cell wall is the cell membrane. In aerobic bacteria, the reactions of cellular respiration take place on fingerlike infoldings of the cell membrane. Ribosomes are scattered throughout the cytoplasm, and the DNA is generally found in the center of the cell. Many bacilli and spirilla have flagella, which are used for locomotion in water. A few types of bacteria that lack flagella move by gliding on a surface.
What happens to bacteria at -18 degress?
Bacteria can survive at -18 degrees Celsius, but they become dormant and their metabolic activities slow down significantly. Freezing temperatures can cause damage to the cell membrane and cell structures, potentially leading to cell death if the freezing period is prolonged.
What is Bacteria and other organisms that cause diseases called?
Pathogenic bacteria are what causes infectous disease. There are different bacterias that cause different diseases. It is believed that there are over 100 BILLION types of bacteria. Tuberculosis is a bacterial caused disease.
How does streptomyces differs from anticomyces?
Streptomyces and Actinomyces are both genera of bacteria, but they are different in terms of their structures and lifestyles. Streptomyces are filamentous, soil-dwelling bacteria known for producing a variety of bioactive compounds including antibiotics, while Actinomyces are branching, anaerobic bacteria found in the human oral cavity and respiratory tract that can cause infections like actinomycosis.
Identify the structure that cause bacteria to move aside from flagella?
Pili or fimbriae are hair-like structures on the surface of bacteria that can help with adherence to surfaces or other cells. Some bacteria can also move using a gliding mechanism, which does not involve flagella but rather a smooth movement across a surface. Additionally, some bacteria can move using structures called axial filaments or periplasmic flagella.
Can flagella be pathogenic?
Flagella themselves are not pathogenic as they are the whip-like appendages that some organisms use for movement. However, bacteria and other microorganisms with flagella can be pathogenic, using the flagella to navigate through their host's tissues and cause infections.

What is deference between protozoans and bacteria?
Protozoans are eukaryotic, single-celled organisms with complex cellular structures and can be parasitic or free-living, while bacteria are prokaryotic, single-celled organisms that are much smaller in size compared to protozoans and have simpler cellular structures. Additionally, some bacteria can cause diseases in humans and other organisms, whereas protozoans are generally not known to cause diseases.
What are parasitic flagellates?
of Flagellum
How does trypanosoma brucei differ from bacteria and multi-celled parasites?
Trypanosoma brucei (cause of sleeping sickness) is a protist with a flagella. It is a eukaryote. It is carried by the tsetse fly and humans. Bacteria are prokarocytes and don't have membrane bound organelles. The other parasite mentioned are different and have many cells. For example, tapeworms.
What structure contributes to the ability of pathogenic bacteria to cause disease?
Capsules (one of the most important virulence factors ( E. coli O157:H7, MRSA, etc.)), lipopolysacharrides in the case of gram negative bacteria, exotoxins like those of clostridium (botulism), hemolytic protein complexes excreted by Staph. aureus, and shiga toxin for shigella, mobility also factor in (Burrelia burgdorferi's endo flagella enables it to corkscrew between your cells creating the radiating pattern associated with Lyme's disease).Type your answer here...
Can prokaryotes move on their own?
prokaryotes move with flagella that allow it to move towards food or away from danger. some bacteria however do not have flagella thus they move in different ways the myxobacteria for example, form a layer of slime; through wavelike contractions of the outer membrane they move the organisms through the slime. and spiral shaped bacteria move by a corkscrew like rotation. filaments inside the organisms cell walls contract and cause the bacterium to turn and move ahead.
What can cause Arthritis?
Bacteria such as Gonococcus can cause Arthritis.
Does bacteria cause gingivitis and if it does which type of bacteria can cause gingivitis?
gram - anaerobes
Cellular components of bacteria that make it a powerful pathogen?
Bacteria have various cellular components that contribute to their pathogenicity, including surface structures like capsules, fimbriae, and flagella for adherence and invasion, as well as toxins that can damage host cells. Additionally, bacterial cell walls can protect against host defenses and aid in colonization of tissues. Some bacteria also possess specific virulence factors, such as secretion systems or biofilm production capabilities, that enhance their ability to cause disease.
