DWT terminology Flashcards
Types of threats
DAMNITV
DAMNITV
Types of threats- degenerative, anomalous (congenital), metabolic, neoplastic, nutritional, infectious, inflammatory, idiopathic, toxic, traumatic, vascular
Animal responses and medical interventions
Anatomic path, clinical path, immunology, pharmacology, epidemiology
Infections agents and toxic principles
Viruses, bacteria, fungi, parasites, toxic principle
Discipline of threats
virology, bacteriology, mycology, parasitology, and toxicology
Disease
Disorder of structure or function leading to clinical disease or sub clinical disease
Diagnosis and management of diseases
Signalment, problem list, differential diagnosis, diagnostic plan, management plan
Infection
Invasions of a host by an agent
Infectious disease
disordered structure or function of the host as a consequence of infection
Outcome of infection is a result of what factors
Pathogen, host, environment
Pathogen-host = Environment
Clinical effects of a pathogen is likely to vary in different environment even if the host is same
Infectious agents
Prions, viruses, prokaryotes, eukaryotes
Prions
Proteins
Viruses
RNA and DNA
Prokaryotes
Cells without nuclei (i.e: bacteria)
Eukaryotes
Cells with nucleus (i.e Fungi with cell walls, protozoa single-celled animal, metazoa multicellular animal)
Agents and their animal associations
Symbiosis, mutualism, commensalism, parasitism, parasitology.
Symbiosis
Organisms live closely together, at least one organism benefits, obligatory or facultative.
Mutualism
both benefits
commenslism
One is benefitted and one is unaffected
Parasitism
One benefits and one is negatively effected
Parasitology
Covers eukaryotic parasites only. May see term used in. place of infectious agents.
Infectious agent transmission
Contact (Direct= animal-animal, Indirect= animal, fomite)
Vehicle (water, food, air- ingestion/inhalation)
Vector (Flies, fleas, ticks. Biological-replication occurs in vector, Mechanical- no replication in vector)
Vertical (Pregnancy, birth, milk)
Zoonotic (animal source of infectious agent to people)
Fomite
unalive
Susceptible host
infectious agents invade
Reservior host
Maintenance of organism in the environment
Amplification host
infectious agents multiply rapidly
Dead-end (incidental) host
No transmission
Pathogen
Infectious agents that can cause disease
- Obligate: host is required niche
-Opportunistic (Facultative): host can be used but is not required
Pathogenicity
Ability of the infectious agent to cause disease
Pathogenesis
series of event leading to disease
Taxonomy
Kingdom, phylum, class, order, family, genus, species
Problem solving loop
- Create a problem list
- Examine the evidence and create differential diagnosis list
- determine which of the DDs is most likely (Presumptive)
- Do some diagnostic tests and interpret these
- Verify
Differential Diagnosis
VINIDICATE
Vinidicate
Vascular, infectious, neoplastic, degenerative, inflammation/iatrogenic/intoxication, congenital, autoimmune, traumatic, endocrine/metabolic
