This population has been trafficked through the thymus and is important in cellular immunity.

M

P3
The third phalanx, or the third bone in a digit.

T cell
A population of lymphocytes that moderates cell mediated immunity.

T cytotoxic cells
Their function is to use perforins and cytotoxins to destroy target cells that are carrying foreign proteins on their surface.

zoonotic Infection
Refers to infectious microorganisms that have the potential to cause disease in humans. Public Health is the study of zoonotic infections.

A = assessment of information
(Modified: 11/29/1999)

B-cell
A population of lymphocytes that produces antibody which provides humoral immunity.

B-cells
This cell population is derived directly from the bone marrow and is important because it gives rise to antibodies (humoral immunity).

Yersinia pestis
Etiologic agent of plague.

zona pellucida
The envelope surrounding the egg or ovum.

zoonoses
A biologically heterogeneous group of infectious diseases.

zoonosis
A disease that can be transmitted from animals to people.

zoonotic disease
Infectious diseases naturally transmitted from vertebrate animals to humans. Some of these diseases can be harbored in a vertebrate animal but there might be a vector involved in transmission, so that is still a zoonotic disease because it is harbored in a vertebrate animal. Additionally the disease may be food or water borne, so you don't need to have direct contact with an animal to acquire a zoonotic disease.

wood's light
An ultraviolet light filtered through nickel oxide. Of the common dermatophytes, only M. canis fluoresces, 25 to 50% of the time.

yearling
Sheep 12 to 24 months of age.

Time milk must be withheld from sale following treatment to avoid appearance of residues in milk.

withholding period
The time after a drug is administered, before the animal can be marketed (or the milk used for human consumption).

Winter Baby Syndrome

A castrated male sheep.

wheal
A circumscribed raised lesion of edemma of the dermas. A large number of wheals is urticaria.

white muscle disease
Another name for a selenium deficiency.

wind up
Sensitization of the central nervous system in response to sustained pain. With sustained pain, new receptors (NMDA receptors)are formed in the central nervous system. These receptors use a very fast neurotransmitter and cause a marked increase in the amount of pain transmitted to the brain. They also prevent opioids from working to their full effectiveness.

WBC
White blood cell. There are several types of WBCs including, neutrophils, lymphocytes, eosinophils and monocytes.

Weaner
Lamb after weaning to 12 months. No exact age but approx from to 12 months.

weight-averaged molecular weight
The sum of the number of molecules at each number-averaged molecular weight divided by the total number of molecules in solution. The weight-averaged molecular weight gives an indication of how long a solution will exert an oncotic effect. Generally, the larger the weight-averaged molecular weight, the longer it lasts.

water soluble vitamins
Includes B complex vitamins and vitamin C. Not normally supplemented for ruminants after two months of age because rumen microbes are able to manufacture enough to meet the animal's requirements.

VPRD

vulva
The opening into the female genital tract from the outside of the animal.

vulva
The external part of the female reproductive tract.

WADDL

The WAC and RCW (Revised Code of Washington) are the interpretation and implementation of state law. These codes are state law.

Vivonex
by Norwich Eaton. A hypoallergenic elemental diet.

By products of digestion in the rumen that make an acidic environment and keep pathogenic bacterial populations down.

von Willebrand's factor
A blood factor that promotes platelet adhesion.

Vitreous
Clear, jellylike substance filling the vitreous chamber, the most posterior cavity in the eye, comprising two-thirds of the volume of the eye. Maintains the shape of the globe.

Never been bred.

virucide
A substance that kills viruses.

Kills viruses

virulence
The ability of an orgnaism to cause disease

virulence
Usually used to define the degree of pathogenicity.

vicryl rapide
An absorbable suture which breaks down in about 2 weeks.

vestibular
Pertaining to balance. The inner ear and the cerebellum of the brain are responsible for maintaining balance.

vestibulum
The area of the female genital tract between the vulva and the vestibular sphincter that opens into the vagina cavity and has on it's floor the opening of the urethra.
