What part of the bacterium can protect it from phagocytosis by white blood cells?
The capsule of the bacterium can protect it from phagocytosis by white blood cells. The capsule is a thick, outer layer made of polysaccharides that can make the bacterium difficult to engulf by phagocytes, thus enabling it to evade the immune response.
What effect does a capsule made of polysaccharides have on a bacterium contained within the capsule?
A capsule made of polysaccharides can protect a bacterium by offering physical protection against desiccation, phagocytosis, and harsh environmental conditions. It can also help the bacterium evade the host immune system by masking its antigens.
What is the capsule of Bacillus anthracis composed of?
The capsule of Bacillus anthracis is composed of polyglutamic acid, which is a unique feature of this bacterium. This capsule helps the bacterium to evade the host's immune system and contributes to its virulence.
What is the function of a bacterium capsule?
The bacterial capsule serves as a protective layer outside the cell wall. It helps the bacterium evade the host immune system by preventing phagocytosis and can also aid in attaching to surfaces or other cells.
How could a capsule increase the pathogenicity of a bacterium?
A capsule surrounds the outside of the cell. Since the chemicals in many capsules are similar to those normally found in the body, they may prevent bacteria from being recognized or devoured by defensive cells of the host. For example, the capsules of Streptococcus pneumoniae enable these prokaryotes to avoid destruction by defensive cells in the respiratory tract and cause pneumonia....uncapsuled strains of these same bacterial species do NOT cause disease b/c the body's defensive cells destroy them.
What is the purpose of bacterium capsule?
Protection

What is a rod or capsule-shaped bacterium.?
Bacillus Cereus is a rod bacteria. Found in dry cereals it is a common cause of exotoxin associated gastroenteritis.

The capsule of Bacillus anthracis is composed of polyglutamic acid, which is a unique feature of this bacterium. This capsule helps the bacterium to evade the host's immune system and contributes to its virulence.
The virulent strain of the bacterium S pneumoniae causes disease because it?
Has a capsule
What protects the bacterium from the hosts immune system?

What surface appendages that allow a bacterium to stick to a surface.?
pili
What is the function of a slime capsule in a bacterial cell?
A slime capsule in a bacterial cell provides protection against desiccation (drying out), phagocytosis by immune cells, and chemical attack. It also helps the bacteria adhere to surfaces and form biofilms.
Of what value is a capsule to a bacterium?
A capsule to a bacterium helps bacteria adhere to surfaces and resist flushing. Several bacteria that have capsules are klebsiella, pneumoniae, bacillus subtillus, and streptococcus pneumoniae.
