    Study Notes

    Microbiology and Ecology

    • The study of the interrelationships between microbes and their environment is called microbiology or microbial ecology.

    Human Microbiome

    • The indigenous microflora of humans is composed of approximately 39 trillion microbial cells, representing thousands of different species.
    • The collective microbes residing on and within a person's body are referred to as the microbiome or microbiota.

    Microbe-Free Zones

    • The following areas of the body are normally free of microorganisms: the brain, spinal cord, and blood.

    Symbiotic Relationships

    • The term used to describe two dissimilar organisms living together in a close association is symbiosis.
    • Examples of symbiotic relationships include mutualism, commensalism, and parasitism.

    Microbial Ecology

    • The study of the interrelationships between microbes and the world around them is called microbial ecology.

    Human Microbiome Characteristics

    • The indigenous microflora of humans plays a crucial role in human health and disease.
    • The human microbiome is dynamic and can change in response to various factors, such as diet, environment, and lifestyle.
