What common virulence factors are found in Neisseria?

HACTEHA [7]

The common virulence factors found in Neisseria are polysaccharide capsule, endotoxin, IgA1 protease, pili, and proteins.

Explanation:

Neisseria species are Gram negative diplococcic highly pathogenic bacteria which cause meningococcal and gonococcal diseases in humans.

Virulence factors of Neisseria meningitidis:

Polysaccharide capsule: Antigenic anti-phagocytic capsular polysaccharides form a capsule and surround the bacterium. About 13 serotypes are present based on which the bacteria is classified.

Endotoxin: Composed of lipooligosaccharides leading to hemorrhage, sepsis, and petechiae on skin

IgA1 protease: Enzyme that breaks and cleaves the antibody IgA

Pili: Attaches bacterium to respiratory tract cells. Acts antigenic against the body’s immune system.

Diseases: Meningococcal - Meningitis, meningococcemia

Transmission: Respiratory tract

Virulence factors of Neisseria gonorrhea :

Pili: Complex gene codes for hypervariable genomes and antigenic against antibodies

Protein porins of outer membrane: Two protein complexes – Por A and Por B – facilitates invasion of epithelial cells

Opaproteins – facilitates attachment and further invasion of epithelial cells.

Diseases : Gonococcal – epididymitis, prostitis etc in men and pelvic inflammatory disease in women

Transmission: Sexual transmission

Why would spinach leaves be helpful to replace damaged heart tissue? State your answer as a claim. Support your claim with evide

Svetradugi [14.3K]

Answer:

Spinach leaves would be helpful to replace damaged heart tissue because they can replace the damaged blood vessels with the ones that the leaves have.

Explanation:

According to this article, scientists can use spinach leaves to replace the damaged heart tissue by extracting the branching network of the leaves, which is the one that distributes water and nutrients in the leave, we can say that they have the same function as blood vessels in our body. With this network of thin vessels, which is very hard to reproduce with a 3D printer, scientists bathed the structure in human cells that can grow around it since they would be nourished by it. As a result, the tissue will grow from this. The goal is to replace damaged tissue using leaves, this has not been successfully done yet, but scientists have made improvements in this area.
