Ksju [112]

Microbial antagonism is the inhibition of pathogens growth by antagonist microbiota. When the resident microbiota prevents the establishment of a pathogen, it is called Microbial antagonism.

<h3>What are antagonist microbiota?</h3>

Antagonist microbiota are the organisms, like bacteria or fungi, capable of acting as a biological control to avoid other pathogenic agents' establishment.

These organisms share three characteristics,

a) capability to quickly colonize a new surface and effectively persist on it

b) better ability than the pathogen to get nutrients

c) the capability of surviving under different environmental conditions.

These antagonists are

genetically stable,
their nutritious requirements are not demanding,
they are capable of surviving under adverse environmental conditions,
they have a high reproductive capability, and
are not pathogenic to their host.

The mechanisms these antagonists use to inhibit the pathogen growth and establishment are among others, antibiosis, competition for resources, lytic enzyme production, and parasitism.

When the resident microbiota prevents the establishment of a pathogen, it is called _microbial antagonism_.

Although the cause of Parkinson's disease is unknown,research indicates that it may be due to defective nuclei in the cells of t

o-na [289]

Answer:

Nervous System could be studied as a direct result of having defective nuclei and may shed light on the cause of Parkinson .

Explanation:

PASRKINSON DISEASE -: Parkinson's disease is a progressive nervous system condition. Several regions of the brain are affected by the condition, especially an area called substantia nigra that regulates balance and movement.

A trembling or shaking (tremor) of the limb is often the first sign of Parkinson's disease, particularly when the body is at rest. Typically, on one side of the body, the tremor starts, usually in one hand. The head, legs , feet, and face can also be affected by tremors. Other hallmark symptoms of Parkinson's disease are rigidity or rigidity of the limbs and body, slow movement (bradykinesia) or inability to move (akinesia), and impaired balance and coordination (postural instability).

Emotions and thinking ability (cognition) can also affect Parkinson's disease. Psychiatric disorders such as depression and visual hallucinations are created by some affected persons. There is also an increased risk of developing dementia in people with Parkinson's disease, which is a loss in intellectual functions, including judgment and memory.

Hence , the answer is the nervous system and other regions of brain where the disease has a direct result of having a defective nuclei and may shed light on the cause of Parkinson .
