Term
Pathogens
Definition
Microorganisms that cause disease.
Term
Frank pathogens
Definition
Normal hosts. Survival usually depends on replication in a host.
Term
Opportunistic host
Definition
Hosts with compromised immune systems. usually commensal bacteria; the normal flora in/ on the host.
Term
1 Adhere to host
2 Enter the host
3 Avoid host defense mechanisms
4 Multiply and spread in the host
5 Damage the host
Definition
Traits of Pathogens
Term
Don’t consistently cause damage.
Definition
Organisms are usually not pathogens if they
Term
Toxins
Definition
Pathogen damage is classified by the use of what?
Term
Virulence
Definition
Microbial specialization that helps it replicate in a host.
Term
1 Gain of virulence through loss of independence
2 Pathogens evolved from benign parasites
Definition
2 major theories on the development of virulence
Term
Lewis Thomas
Definition
Who said " It appears more like a biological mix-up than an evolutionary advantage." ?
Term
1 Transmission of the pathogen
2 The hosts immune system
3 Rate of the pathogens reproduction
4 Large populations
Definition
Factors influencing evolution of virulence.
Term
1 Development that aid in the host to host transfer
2 Overdeveloping one aspect to compensate for a deficient aspect
Definition
Pathogen's developments which promote virulence.
Term
Point mutations
Recombination
Horizontal gene transfer
Definition
Different genetic events that will regulate virulence.
Term
Type of specimen
Type of pathogen
Definition
Choosing a diagnostic method depends on:
Term
Tissue
Blood
Urine
Mucous
Definition
Types of specimen:
Term
Isolate in culture
Identify the isolated organism
Definition
Traditional approach to identification of infectious agents
Term
Specific antigen detection
Nucleic acid techniques
Direct examination
Definition
Other approaches to identification of infectious agents
Term
Antigen
Definition
Molecule that produces an immune response.
Term
Nucleic acid techniques
Definition
This technique of infectious agent identification uses probes and gene amplification.
Term
to get a specimen that best represents the disease process
Definition
What is the gal of specimen collection?
Term
Optimal times
Optimal sites
Specimen quantity
Definition
What factors should be considered when collecting specimens?
Term
Antibiotics
Definition
Cultures should be done before the administration of what?
Term
As close to time of death as possible.
Definition
When should necropsy cultures be done?
Term
> 1ml
Definition
How much body fluids should be collected for specimen evaluation?
Term
> 3 cubic centimeters
Definition
How much tissue should be collected for a tissue specimen sample?
Term
Nutrient broths
Definition
What should specimen not be transported in?
Term
Anaerobic bacteria
Definition
This type of bacteria should be collected via aspirate using a sterile syringe and fine gauge needle.
Term
Anaerobic bacteria
Definition
When in doubt treat bacteria as what?
Term
Aerobic bacteria
Definition
This type of bacteria requires oxygen
Term
anaerobic bacteria
Definition
This type of bacteria requires a lack of oxygen
Term
Brightfield
Definition
What is the most common microscopy used in veterinary medicine?
Term
Darkfield
Definition
This type of microscopy applies light to a specimen at an oblique angle.
Term
Fluorescence
Definition
This type of microscopy uses fluorescence dyes.
Term
Immunologic testing
Definition
Used to detect presence of a pathogen or an immunologic disorder.
Term
Passive transfer
Definition
newborns obtain maternal antibodies in colostrum from the mother to protect themselves until they can make their own.
Term
Precipitation
Definition
Uses the reaction of an antigen binding to an antibody.
Term
Rapid latex Agglutination
Definition
Used for direct detection of bacterial or fungal antigens
Term
Compliment
Definition
Proteins that react with antigen/ antibody complexes.
Term
Compliment Fixation
Definition
This has been replaced with ELISA in most labs.
