IMHA treatment

-improve oxygenation -managing immune response

Immune mediated thrombocytopenia

This is when platelets are attacked by the immune system

thrombocytopenia

What is the most common clinical sign for ehrlichiosis?

Ehrlicia treatment

-not all positive dogs are infected or will progress to the chronic phase -treatment may not eliminate infection -reinfection can still occur -treatment of healthy dogs may result in antimicrobial resistance

serology

What is the best way to diagnose Ehrlichia?

Coomb's test

FIV

-infection that disrupts immune system function -outdoor, free roaming, intact male cats are most at risk -transmitted through bites and body fluids -acute, subclinical, and clinical phases -should be microchipped after vaccination because vaccinations will cause false positives on tests

bites/body fluids

How is FIV transmitted?

DIC

excessive intravascular coagulation that leads to multisystem organ failure

DIC causes

bleeding from venipuncture sites

What is the most notable clinical sign that could clue your patient was in DIC?

PTT

Which coagulation test is more sensitive for detecting DIC?

DIC treatment

-aggressive treatment for primary disease -maintain tissue perfusion and oxygenation -heparin

rodenticide poisoning

-dyspnea -bleeding -hematoma -muffled heart and lung sounds -pale MM -lethargy -depression

reduction in vit K-1

What causes rodenticide clinical signs?

rodenticide poisoning treatment

-emetics -vitamin K-1 -whole blood or plasma

IV K-1

Which route of the antidote for rodenticide poisoning can result in anaphylaxis?

immunity

________________ is a defense against or resistance to, contagious diseases

species resistance

_______________ _____________ refers to the genetic ability of a particular species to provide defense against certain pathogens

inflammation characteristics

-pain -redness -swelling -heat

true

true or false: the goals of inflammation are to kill the pathogens, remove the tissue debris, and repair damaged tissues

interferon

a substance that interferes with a virus's ability to cause disease by preventing it from replicating within the host

complement

binds to the invading cell, makes small holes in the cell membrane, and causes the cell to rupture

macrophage

________ will attach to foreign substances and take it to the T-cell

b-cells

mediate the production of antibodies in response to an antigen

false

true or false: each antibody produced is specific for up to 3 different antigens

inherited

___________ immunity is a result of genetic factors that influence that developing animals before birth

acquired

______________ immunity is a resistance that develops after an animal is born

passive

___________ immunity is when antibodies are formed in one animal and transferred to another animal that is not infected. This transfer provides the uninfected animal with protection against the pathogen

True

True or False: Artificial immunity is usually due to deliberate exposure with vaccinations

cell mediated immunity
