How does bacteria affect the nervous system?

How does bacteria affect the nervous system?

Bacteria that cause meningitis often gain access to the CNS through the bloodstream after trauma or as a result of the action of bacterial toxins. Bacteria may also spread from structures in the upper respiratory tract, such as the oropharynx, nasopharynx, sinuses, and middle ear.

What are two infections of the nervous system?

These infections mainly involve meningitis, encephalitis, and brain abscesses, and tend to cause more morbidity and mortality on average than infections involving other organ systems.

Does coronavirus affect the nervous system?

However, some people who have had only mild or moderate symptoms of COVID-19 continue to experience dysfunction of body systems—particularly in the lungs but also possibly affecting the liver, kidneys, heart, skin, and brain and nervous system—months after their infection.

Which virus affects nervous system?

Viral diseases of the central nervous system encompass a wide range of different processes, mainly inflammation affecting the brain (encephalitis), the meninges (meningitis), or a combined meningoencephalitis. The spinal cord can be affected as well (myelitis).

What bacteria attacks the nervous system?

Great strides have been made in understanding the mechanisms by which bacterial pathogens with a predominantly extracellular life cycle, such as Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae, invade the CNS from the bloodstream (for recent reviews, see references 172, 196, 206, 274, and …

What are symptoms of nerve damage?

Most infected people do not develop symptoms. Neurological complications such as Guillian-Barré-like syndrome, neuropathy and myelitis can occur in adults as well as in children.

How do you fix nerve damage?

Sometimes a section of a nerve is cut completely or damaged beyond repair. Your surgeon can remove the damaged section and reconnect healthy nerve ends (nerve repair) or implant a piece of nerve from another part of your body (nerve graft). These procedures can help your nerves to regrow.

Can a bacterial infection affect the nervous system?

Bacterial infections that affect the nervous system are serious and can be life-threatening. Fortunately, there are only a few bacterial species commonly associated with neurological infections.

Can a virus cause damage to the nervous system?

The measles virus may do this, causing a chronic progressive encephalitis that is usually fatal. Direct infections of muscles and of peripheral nerves are uncommon except in leprosy. Both the central and peripheral nervous systems may be severely damaged by an immune system reaction after relatively trivial infections elsewhere in the body.

What are the different types of central nervous system infections?

slide 1 of 6. Types of Central Nervous System Infections A central nervous system infection can be classified as viral, bacterial, fungal, or protozoal. These infections either affect the brain directly, or through the membrane, or meninges, which covers the brain and spinal cord.

Are there any diseases that affect the nervous system?

Bacterial infections that affect the nervous system are serious and can be life-threatening. Fortunately, there are only a few bacterial species commonly associated with neurological infections. Bacterial meningitis is one of the most serious forms of meningitis.
