Define symbiosis |
To live together |
|
|
The three types of symbiosis |
Mutualism, commensalism, parasitism |
|
|
Give an example of mutualism |
Bacteria in human colon |
|
|
Give an example of commensalism |
Staphylococcus on skin |
|
|
Give an example of parasitism |
Tuberculosis bacteria in human lung |
|
|
Two types of microbiota... |
Resident and transient |
|
|
These are a part of normal microbiota throughout life... |
Resident microbiota |
|
|
These microbiota remain in the body for a short period of time and they are found in the same region as resident microbiota. They cannot persist in the body. |
Transient microbiota |
|
|
Normal microbiota that cause disease under certain circumstances are known as... |
Opportunistic pathogens |
|
|
The most common cause for a condition that provides opportunities for pathogens is... |
Immune suppression |
|
|
Sites where pathogens are maintained as a source of infection but no harm is caused. |
Reservoirs of infection |
|
|
Animal reservoirs are known as... |
Zoonoses |
|
|
Give some examples of non-living reservoirs of infection. |
Soil, water and food |
|
|
The mere presence of microbes in or on the body is... |
Contamination |
|
|
Name the three major pathways pathogens enter the body. |
1. Skin 2. Mucous membranes 3. Placenta |
|
|
Subjective characteristics of disease only felt by the patient... |
Symptoms |
|
|
Objective manifestations of disease observed or measured by others... |
Signs |
|
|
Symptoms and signs that characterize a disease or abnormal condition. |
Syndrome |
|
|
Name the three groups of infectious disease transmission. |
1. Contact 2. Vehicle 3. Vector |
|
|
This type of transmission involves body contact between hosts, droplets of mucous or spread via fomites. |
Contact Transmission |
|
|
This type of transmission occurs in airborne, waterborne, foodborne or bodily fluid transmission. |
Vehicle Transmission |
|
|
This type of transmission occurs through biological (biting arthropods) or mechanical vectors (passively transmit pathogens present on their body to new hosts). |
Vector Transmission |
|
|
Stages of Infectious Disease are... |
1. Incubation 2. Prodromal 3. Illness 4. Decline 5. Convalescence |
