Hepatic: pertaining to the liver.>
Humoral Immunity: the component of the protective immune response that is mediated by antibodies formed by B Lymphocytes.
Hyperemic: focal reddening of an area due to excessive blood in the area caused by inflammation.
Immune Mediated Vasculitis: vascular inflammation that is immune mediated (caused by ones own immune response) and leads to vascular damage and increased permeability.
Immune Response: the response of the body to substances that are not recognized as self., resulting in a cell mediated and humoral response.
Immunity: non-susceptibility or reduced susceptibility to infection and/or clinical disease by an invading micro-organism, parasite, or toxin.>
Inactivated Vaccine: vaccines made of viruses that are inactivated so they are no longer able to grow or damage tissue.
Infarction: the formation of a localized area of ischemic necrosis formed in response to arterial or venous inclusion.
Ischemic Necrosis: necrosis of tissue due to disruption of its blood supply.>
Keratoconjunctivitis: inflammation of the cornea of the eye and of the conjunctiva (tissue around the eye).
Latent Carrier: an animal which carries a disease in its system without manifesting any clinical signs.
Lymphadenopathy: any disease of the lymph nodes.
Macrophage: mononuclear phagocytic white blood cells that arise from the bone marrow and are activated by the inflammatory response.
Meconium: first stools passed by the newborn, consisting of yellow-orange mucilaginous material.
Modified Live Vaccine: also called attenuated vaccine. A vaccine prepared from live virus that have been altered to lose their virulence or ability to cause disease.
Myocardium: the middle layer of the heart wall that is composed of muscle.
Necrosis: morphological cellular changes caused by cell death due to enzymatic degradation>
Neurotropic: pertaining to nervous control of maintenance or nutrition of other tissues.
Neutrophils: a type of white blood cell that participates in the immune response, usually early in infection.
Opisthotonus: a type of spasm whereby the head and tail are bent upwards, associated with a brain lesion located in the brainstem.
Pathogenesis: changes that occur in an animal during the development of disease.
Parturition: the process of giving birth.
Perineum: the region between the tail and the genital organs.
Perivascular Cuffing: accumulation of lymphocytes and /or plasma cells around a vessel, indicative of inflammation or an immune mediated reaction.>
Petechial Hemorrhage: pinpoint hemorrhage.<>>>
<>Pharmacokinetics: the study of the movement of drugs within the body, including their absorption, distribution, metabolism and elimination.>
Polymerase Chain Reaction (PCR): the amplification of a sequence of DNA which helps to identify cellular organisms or viruses.
Prophylactic antibiotics: treatment with antibiotics used to prevent or minimize infection.
Pulmonary Disease: disease that pertains to the lungs.>
Quadriplegia: paralysis of all four limbs.
Quarantine: restricted entry or exit from a premises for a stated period of time where a infectious and contagious disease is suspected or present.
Recrudescence: Reoccurrence of clinical signs after a period of time with no clinical signs.>
Recumbent: an animal that is lying down and unable to stand.>
Respiratory Disease: Disease pertaining to the respiratory tract (this includes the nasal cavities, the pharynx, larynx, trachea, bronchi and the bonchioles and alveoli within the lungs).
Rhinopharyngitis: inflammation of the nose and pharynx.
Rhinopneumonitis: inflammation of the nose and lungs.
Sequelae: A secondary illness or disease that occurs following or as a consequence of the primary condition or event.
Serotype: a taxonomic classification of a microbe based on the body’s ability to neutralize it with a specific serum antibody.>
Subclinical: When an infection or disease is present but cannot be observed on a clinical exam by the veterinarian or the client.>
T Lymphocytes: type of white blood cell involved in immune protection. T cells act by releasing compounds that are harmful to invading cells as well as by directly killing invading cells.
Tracheobronchitis: inflammation of the trachea and bronchi.
Tropism: exhibited when a virus shows a particular affinity for a certain host species and/or type of tissue.
Ulcerated: local defect caused by necrosis and sloughing of inflammatory tissue that removes the basement membrane.>
Viremia: the presence of virus particles in the blood.
Virus: an infectious organism that is characterized by its small size and inability to replicate outside of the living host. The genome consists of either DNA or RNA and is surrounded by a protein coat.
Zoonotic: any disease that can be transmitted from animals to people, or from people to animals.
