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.

<u>Virulence factors of Neisseria meningitidis</u><u>: </u>

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

<u>Virulence factors of Neisseria gonorrhea :</u>

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

As part of a psychology lab, you squirt sea water at an Aplysia's gills. After doing this several times, the Aplysia retracts it

pshichka [43]

Answer:

The Aplysia withdrawing it's gills is demonstrating a gill and siphon withdrawal reflex (GSWR) phenomenon

Explanation:

The hill and siphon withdrawal reflex (GSWR) is involuntary and a defensive reflex. This reflex causes delicate siphon and gill to be retracted when an animal is disturbed.

A two-component reflex is triggered when weak or moderate stimulus is applied to a siphon or the mantle shelf. These two components consist of two reflex acts, the siphon-withdrawal reflex and the gill-withdrawal reflex. Together they often form a reflex pattern with short latency that protects the animals gill and siphon to potentially threatening stimuli.

An habituation in an Aplysia californica for example is which is an Aplysia gills is when a stimulus is presented continously to an animal and there is a progressive decrease in response to that particular stimulus.
