Micropara Flashcards
For the Midterms (33 cards)
the types of organisms present in specific regions of the body
Microbiota
Is the study of the relationships between microorganisms and their environment.
Microbial Ecology
group of organisms that inhabit the body of a normal healthy individual in the community
Normal Flora
These indigenous flora may be;
non-pathogenic or pathogenic
Found in a given area of the body at a given age.
Resident Flora (Normal flora)
Inhabit the skin and mucous membrane temporarily for hours, days, or weeks and are derived from the environment. They do not establish permanently in the body tissues.
Transient Flora
Benefits
Inhibit the growth of pathogenic organisms.
Protects the body’s organs and systems that are in direct contact to the external environment.
Synthesize important vitamins essential to humans.
Aid in digestion of food
Metabolism of steroid
There are certain body tissues and fluid that are normally sterile.
True
Sterile Body Fluids
Cerebrospinal fluid
Synovial fluid
Blood
Sterile Body Tissues
Urinary bladder
Uterus
Fallopian tube
Middle ear
Paranasal sinuses
What is an example of a body fluid infection
Septic Arthritis (Joint Inflammation)
What is an example of body tissue infection
Urinary Tract Infection (UTI)
The sites of the human body inhabited by microorganisms include the mouth, nasal cavities, throat, stomach, intestines, urogenital tracts, and skin.
True
is estimated that the microbes in the human microbiome number around 1013 cells (same number as human cells)
True
A concept that describes the interaction between a host organism and its resident microbiome as a single, integrated unit
Host-microbiome supraorganism
Following the removal of the disturbance, an individual’s unique microbiome tends to reemerge.
True
Normal Flora consist of:
Bacteria & Fungi
The skin is divided into three regions (What are these?)
Axilla, perineum, and toe webs
Hand, face, and trunk
Upper arms and legs
Examples of skin organisms:
Staphylococcus epidermidis
Staphylococcus aureus
Micrococci (Micrococcus luteus)
Diphtheroids (Coryneforms)
Gram-negative Bacilli (Enterobacter, Klebsiella, Escherichia coli, and Proteus spp.)
Nail flora
Microorganisms in the skin are common in the…
Nose & perineum
Normal flora in the mouth (locations)
Tongue & Bucal Mucosa
Gingival Crevices & Tonsillar crypts
Normal Flora in the respiratory track (Location)
Pharynx & Trachea
Upper and Lower Respiratory Track
Normal Flora In the Digestive track (Location)
Esophagus
Stomach
Hostile environment of the stomach destroys microorganisms. This is due to?
Acidity or Low pH
