  • But damage is caused due to attack by autoimmune cells or antibodies against myelin sheath.

Types of tissues attack:-

  • Oligodendrocytes and myelin sheath is damaged and stripped away from axon and the process is known as demyelination.
  • Myelin sheaths are made up of fatty tissues and help in transmission of electric impulse.

Result of immune system attack:-

  • Damaged myelin sheath stop forming whIte matter of central nervous system.
  • Hence disrupt coordinating communication between different brain regions.

Signs and symptoms:- vary from person to person

  • Diminished eyesight.
  • Disrupt motor coordination.
  • Weak sensory perception.

Differentiate between persistent and latent animal virus infections.
lana66690 [7]

Answer:

The difference between both infections is that viral infections where the virus is latent, this virus once infected is protected in the nerves of the animal organism, as for example in humans the herpes family viruses (HSV1) are housed in ganglionic terminals such as the trigeminal ganglion or the V cranial nerve, so that in a situation of immunodepression, reinfect the individual again, causing him to be unable to remove the virus from his body.

On the other hand, persistent infections diseases are the threats that persist because the microorganism cannot be eliminated, either because it is very complex, or the cure does not exist, or the correct treatment is not carried out. Furthermore, it is necessary to consider that some microorganisms mutate becoming resistant to these drugs and thus persist longer in the body until they are eliminated.

Explanation:

In short, latency refers to the fact that the individual lives with the virus for life, and persistence is that it is possible to eliminate it over a long period of time since the infectious microorganism is considered very difficult.
