Infectious Diseases Flashcards
You touched the infected person
Sex, airborne mucous droplets, fecal contamination, oral transmission
Direct transmission/contact
Produce effects related to inflammation Powerful bronchoconstricters Involved in asthma Powerful vasodilators Produce a lot of vascular collapse found in anaphylaxis
Leukotrienes
The organism survives on animate or inanimate objects for a time w/o human host.
Air, food, water, soil, biological matter
Indirect transmission/contact
Prokaryotic Can self-reproduce Produce toxins Release endotoxins(proteins) Can cause local or systemic infection
TB, Staph, Strep, Ecoili, Salmonella
Bacteria
No nucleus
Need host to reproduce
Many cannot survive outside a host
Contain other microorganisms
Flu, Cold, HIV, Hep, Herpes
Viruses
Eukaryotic
Surrounded by a capsule to protect from phagocytes
Fungi
Single-cell microorganisms
More complex than bacteria
Giardia, Amebic dysentery
Protozoa
Pathogenic parasites
Not necessarily microorganisms
Tapeworm, ringworm
Helminths
Produce effects related to inflammation
Help maximize WBC response against foreign substances like bacteria
Produce fever, related to illness
Interleukins
Produce effects related to inflammation
INCREASE:
Vascular & cell membrane permeability
Vasodilation
Bronchoconstriction
Blood clotting by activating platelets
Stimulation of pain nerves during tissue damage
Prostaglandins
A person whose hx or s/s suggest they may have/developing a communicable disease
Suspect
A person who provides an environment for growth of an infectious organism
Host
A carrier
Usually an insect
Transmits an organism from one organism to another
Vector
The process of picking up the infectious agents
Infection
The time between infection and the development of s/s of the disease
Incubation Period
