PREPARATION
What is serology
the study of detection + measurement of antibodies and antigens
What are 3 main types of serology testing performed in vet medicine
,1. latex agglutination
2. enzyme linked immunosorbent assay (ELISA)
3. rapid immunomigration (RIM)\
What is a latex agglutination
suspension of small, latex beads that have coated antibody is added to serum sample
(if corresponding antigen is present it will react= visible clumping)
What is ELISA
*most commonly used test
-detects the presence of antigen
What is RIM
Rapid Immonomigration or Lateral flow assays
- this is the accumulation of colloidal gold that causes a color change
**most expensive test
What is a serum chemistry evaluation testing
Function + electrolytes of...
-liver
-kidney
-pancreas
-gallbladder
What are two ways to do serum glucose testing
1. use serum of blood previously collected in serum analyzer machine (most accurate)
2. use glucometer to gather blood sample to test blood sugar levels
What is activated partial thromboplastin time (PTT)
measures the time it takes for fibrin clot to form after calcium and activator are added to
blood sample
What is prothrombin time (PT)
measures the amount of time it takes for fibrin clot to form after calcium and tissue
activating factor are added to blood sample
What is thrombin time (TT)
the conversion of fibrinogen to a fibrin clot
Clotting times/testing
do they have enough platelets to clot (liquid vs solid)
Immunology -ANSWER✅✅✅Study of a host's reactions when foreign substances are
introduced into the body
Antigens -ANSWER✅✅✅Foreign substances that induce a host response
Immunity -ANSWER✅✅✅The condition of being resistant to infection
Edward Jenner -ANSWER✅✅✅Successfully prevented infection with smallpox by
injecting a more harmless substance- cowpox from a disease affecting cows
Louis Pasteur -ANSWER✅✅✅Father of immunology- observed by chance that older
bacterial cultures would not cause diseases in chickens (first attenuated vaccine)
Used attenuation to prevent rabies in affected individuals
,Attenuation -ANSWER✅✅✅Change- make a pathogen less virulent (heat, aging, or
chemical means)
Phagocytes -ANSWER✅✅✅Cells that eat- part of natural or innate host defense
humoral immunity -ANSWER✅✅✅specific immunity produced by B cells (plasma cells)
that produce antibodies that circulate in body fluids
Antibodies -ANSWER✅✅✅Serum proteins produced by certain lymphocytes when
exposed to a foreign substance and they react specifically with that foreign substance
Innate (natural) immunity -ANSWER✅✅✅The individual's ability to resist infection by
means of normally present body functions
Adaptive immunity -ANSWER✅✅✅Type of resistance that is characterized by
specificity for each individual pathogen, or microbial agent, and the ability to remember
a prior exposure
increased response to that pathogen upon repeated exposure
Leukocytes -ANSWER✅✅✅White blood cells in the peripheral blood that play a key
role in both innate and adaptive immunity
5 principal types of leukocytes in peripheral blood -ANSWER✅✅✅Neutrophils,
eosinophils, basophils, monocytes, lymphocytes
Innate immune cells in periphery -ANSWER✅✅✅Neutrophils, eosinophils, basophils,
monocytes
Adaptive immune cells in periphery -ANSWER✅✅✅Lymphocytes
Tissue cell lines -ANSWER✅✅✅Mast cells, macrophages, and dendritic cells
All blood cells arise from a type of cell -ANSWER✅✅✅Hematopoietic stem cell (HSC)
HSC gives rise to two distinct types of precursor cells: -ANSWER✅✅✅Common
myeloid precursors (CMP) and Common lymphoid precursors (CLP)
The common myeloid precursor gives rise to: -ANSWER✅✅✅Phagocytic cells:
Monocytes/Macrophages, Neutrophils, Eosinophils, Basophils, Erythrocytes, Platelets
The common lymphoid precursor gives rise to: -ANSWER✅✅✅T/NK progenitors (T
and NK cells) and B cell progenitors (B cell and dendritic cells)
Neutrophils -ANSWER✅✅✅Polymorphonuclear neutrophilic leukocyte
, 50-75% of total peripheral WBCs in adults
Azurophilic or primary granules -ANSWER✅✅✅Contains antimicrobial products such
as myeloperoxidase, lysozyme, elastase, proteinase-3, cathepsin G, and defensins
secondary granules -ANSWER✅✅✅Lysozyme, lactoferrin, collagenase, gelatinase,
and respiratory burst components
Diapedesis -ANSWER✅✅✅Passage of white blood cells through intact vessel walls
into tissue
Chemotaxins -ANSWER✅✅✅chemical messengers that cause cells to migrate in a
particular direction
Eosinophils -ANSWER✅✅✅1-3% of the circulating WBCs in a nonallergic person
Eosinophil granules -ANSWER✅✅✅Catalase, lysozyme, cytokines (chemical
messengers), growth factors, and cationic proteins
Role of eosinophils -ANSWER✅✅✅Attack parasites and toxic proteins and allergic
responses. Regulation of mast cell function
Basophil -ANSWER✅✅✅<1% in peripheral blood
Short lifespan
Basophil granules -ANSWER✅✅✅histamine, cytokines, growth factors, and heparin
Function of histamine -ANSWER✅✅✅Contracts smooth muscle
Basophil function -ANSWER✅✅✅Regulate T helper cell responses and stimulate B
cells to produce IgE
Monocytes -ANSWER✅✅✅Largest cells in peripheral blood
4-10% of total circulating WBCs
up to 30h and migrate into tissue to become macrophages
Monocytes granules -ANSWER✅✅✅1- peroxidase, acid phosphatase, arylsulfatase
2- B-glucuronidase, lysozyme, lipase
Macrophages -ANSWER✅✅✅Tissue monocytes
Contain no peroxidase
Named according to a tissue location
Lifespan- months
