Flashcards in Asepsis Deck (43):
Micro organism that causes disease
Induce infection to the patient through
Contact with the environment personnel or equipment
Free living important in health and disease. Aerobic or anaerobic. Shape rod or cocci Spirochete.
Can produce resistant spores
Simplest microbe defined by RNA or DNA base. Enveloped or non-envelope. Obligate intracellular parasites, confined to a specific host entirely dependent on that host.
Non-chlorophyl bearing plantlike organisms.
Can produce resistance spores.
Uni cellular organism
Hospital acquired infections are caused by, viral, bacterial, and fungal pathogens
blood stream infection
Surgical site infection
Any in animate object capable of carrying infectious organisms transferring them from one individual to another
Medical asepsis is:
Medial asepsis is referred to as:
- reduce number of pathogens
- referred to as clean technique
Medical asepsis used in administration of :
What is #1 in medical asepsis
Surgical a sepsis is:
Referred to as:
Eliminates all pathogens
Referred to as sterile technique
Surgical asepsis used in:
Term used to describe all the precautions taken to prevent contamination and ultimately infection of a surgical incision
Aseptic technique its purpose
To minimize contamination so that post operative healing is not delayed
Implies the presence of Micro organisms.
Contamination of a wound can but does not necessarily lead to infection
Micro organisms in the body or a wound multiply and cause harmful effects
Any process that detrimentally interferes with the function of an organism. Include abnormality of structure or function
Also known as micro organism a living organism too small to be seen with the unaided eye
Microbes usually found in healthy animal’s
Some of all factors contributing to the ability of an animal to overcome invasion by pathogen’s
Presence of pathogen’s or there by products in blood or tissue of patients
Complete absence of living pathogenic microbes. Not there spores.
Complete absence of microbes and their spores
Not sterile, may or may not be contaminated with microbes
Body of techniques to maintain an object or area as free of all microbes as possible. Used whenever body tissues are penetrated.
Body of techniques used to reduces the number of microbes and the transmission of pathogens
Any cleansing measure intended to prevent dz and promote health; destroys about 98-99% of all microbes
Application of an agent that possess the property of destroying or inhibiting the growth of microbes on inanimate objects. Destroys about 99% of all microbes
Inhibits or prevents growth of microbes on living tissues
Process to rid an object of 100% of all microbes and their spores
Immersion of an object into a disinfectant solution to reduce the level of contamination
Passage of microorganisms from one host to another
Ability of a microorganism to invade a host
Describes the ease of which a microbe is able to invade a new host
How to prevent infection?
Limit FOMITES: clean, santize, disinfect and or sterilize to limit contagion on inanimate objects
How to prevent infection cont:
Isolate infected animals in appropriate areas with no contact with healthy animals. This includes preventing spread of dz through appropriate ventilation, cages, etc.
How to prevent infection cont.
Placing newly acquired animals for several days to weeks in areas not exposed to healthy animals
How to prevent infection cont.
Wash hands, scrub, surgical prep
How to prevent infection cont. PREVENTION
Prevent the spread of microorganisms through vaccines and or use of snit-microbial, education.
How does the HOST prevent infection:
A. Immune sys - white blood cells sys ( t and b cells) lymphatic tissue and sys
B. Physical barriers - skin, hair
D. Specialized cells-collocates cells in respiratory tissue, blood/brain Barrie’s
E. Elimination of wast- urination, vomiting, defeating, sweat
G. Individual cells- phagocytosis, micro enzymes, antigen, recognition, autolysis
How an ANTIGEN overcomes host?
A.release of toxins H1N1 in influenza, sepsis (pyometra)
B. Virulence ability to avoid hosts immunity and invade host
C. Spore formation resistance to extreme temps, detergents
D. Ability to hide from hosts immune system: capsule to prevent antigen recognition, hide in cells DNA or RNA
E. Ability to stick to host: use of pili
F. Ability to spread easily: ability to irritate and destroy tissues which can cause host to cough, sneeze, diarrhea, flagella
G. Ability to replicate: use of host ATP, DNA, RNA, to aid in replication
