PMLS LESSON 8 TRANSES PART 1 Flashcards
process of cleansing an object or substance to remove contaminants such as microorganisms and hazardous materials.
Decontamination
Decontamination is important because reliability of test results stems from ____________ and ___________ can only come from clean work surfaces free of ____________.
good microbiological practice,
good microbiological practices
contamination
what is the primary objective of decontamination?
to reduce the level of microbial contamination so that transmission is eliminated
Causes erroneous results by either interfering in the identification of microbiological agents and cultures
contamination
what does contamination serves as?
serves as a gateway for biosafety breaches
Decontamination relates to?
Biosafety and biosecurity
decontamination of equipments and work surfaces should be done?
routinely
what are the routines done in decontamination of equipments and work surfaces?
After spills or contamination
When work is finished
When removing equipment from the lab
Before disposal of potentially infection materials
Before reusing potentially infectious materials
Dusting
refer to the process
of cleaning work surfaces such as work benches and
counter tops
dusting
can betransmitted directly or indirectly from environmental sources
to laboratory staff
Environmentally associated laboratory infections
LAI meaning ?
Laboratory Acquired Infections
how many LAI Reports were published in the year 1982 between 2016
27 LAI Reports
what is the percentage of the most reported pathogens causing LAIs of the dengue virus?
33%
what is the percentage of LAI reports that are recorded in Southeast Asia
11%
27 LAIs were published in the year of ?
it was published in the year between 1982 and 2016
the percentage of LAIs where most reagents are involved
59%
is the most common cause for laboratory acquired
infection
dengue virus
they are the agents involved in bacterial infections
bacterial origin
how do we prevent laboratory acquired infections?
look at the chain of infection
enumerate the chain of infections
- Infectious agents
- Reservoir
- Portal of exit
- Mode of Transmission (FAW)
- Portal of entry
- Susceptible Host
Refers to your etiologic agents such as bacteria, fungi, viruses or even parasites.
infectious agents
Refers to how the infectious agents get out of the reservoir.
- Portal of exit
Refers to your etiologic agents such as bacteria, fungi, viruses or even parasites.
infectious agents
necessary for the survival of these infectious agents.
reservoir
part of the life cycle of the infectious agent but not strictly part of their life cycle
reservoir
The mode at which the agent is transmitted
mode of transmission
Refers to how the infectious agents get in of the reservoir.
portal of entry
Reduction of environmental microbial contamination by
________________ is often enough to prevent environmentally immediate transmission.
conventional cleaning procedures
the _________ of any one of the element of the chain of infection will prevent transmission
absence
what must be required for the chain infection to happen?
all of the requirements must be required for it to happen
how do you accomplish a successful transmission from an environmental source?
o All of these requirements from the chain of infection must be present.
oThe absence of any one of element will prevent transmission
oAdditionally, the pathogen in question must overcome environmental stresses to retain viability, virulence, capability to initiate infection in the host
