Detailed explanation-1: -Normal flora includes the microbes that permanently reside in a specific body site and is also known as resident flora. In contrast, transient flora is only temporarily present in the superficial regions of the body.

Detailed explanation-2: -Normal flora is found in all areas of the human body exposed to the environment (one exception is the lungs), but internal organs and body fluids are considered sterile in a healthy individual. This is generally true, although bacteria are sometimes found in these “sterile” tissues even in healthy people.

Detailed explanation-3: -Even though most elements of the normal microbial flora inhabiting the human skin, nails, eyes, oropharynx, genitalia, and gastrointestinal tract are harmless in healthy individuals, these organisms frequently cause disease in compromised hosts.

Detailed explanation-4: -Many normal flora organisms are not pathogenic as long as the host is in good health. However if host resistance mechanisms fail-either through some other infection process or through immunodeficiency, these normal flora organisms become pathogenic.
