Infection Control Flashcards
What is Infection ?
An invasion and growth of microorganism in body tissue that cause harm to the cell tissue
are too small to be seen with the naked eye
and grow in or on a host which cause infectious disease is ?
Microorganism
Where micro organisms can be found ?
They can multiply in large number and can cause obstruction ( tissue damage )
Secrete organic substance called toxins
Has side effects such as: high body temperature, nausea, and vomiting
Microorganisms is encouraged by ?
A warm dark moist environment
To live they must have :
moisture , nutrients and Suitable temperature
Resistant form of the bacterium that is produced within the cell ?
Endospores
( can remain viable for many years )
Example : Bacillus and Clostridium
Different Classification of Microorganism ?
Bacteria , Viruses , Fungi and Parasite, Protozoa, Rickettsia and Prions
Microorganisms that don’t cause a disease and they are used in food / drug processing ?
Normal Microbial Flora
Example : E.coli is normal flora of GIT
Which process is defined as the interaction between the pathogenic micro organism ?
Chain of infection
Such as : Infectious agent , Reservoir host , Portal of exit , Route of transmission
and Portal of entry
A person who serve as reservoir ?
Called carrier
Which is an infected person who does not display the disease symptoms
( Medical Asepsis) ( Handwashing)
Like : asymptomatic HIV patient
where an infectious organism can remain alive
and from it transmission occur?
Reservoir
Escape from the reservoir from blood or secretions like respiratory is called ?
Portal of Exit
The routes of transmission from reservoir to the host is ?
Mode of Transmission
Such as : Direct contact , by means of a fomite , by means of a vector and by means of a vehicle
Skin to skin contact ( HIV)
Direct contact ( Syphilis - skin infectious disease)
Example : ( touching a person with an infection can pass on infection)
Is an object that has been in contact with pathogenic organisms and then used for another person ?
By means of fomite
Like : Contaminated urinary catheter
Is an infected insects that transmits infection to humans like Malaria ?
By means of vector
