- 2) Babesiosis
- 3) Toxoplasmosis
Metazoan zoonosis diseases
- 1) Scabies
- 2) Cestodes
- 3) Nematodes
What does etiology mean?
- Organism causing the disease
- EX: Bubonic plague= Yersinia pestis
What does titer mean?
- Relationship of antibodies to antigen in ratio terms
- EX: Titer of 1:10 means 1 antibody to 10 antigens
What is a host?
- Patient that is paratizied by etiological agent
- EX: Dog is the host and flea is the parasite
What is epizooliology?
Relationship of various factors which determine the frequency and distribution of infectious disease
What does TVMDL stand for?
Texas veterinary medical diagnostic laboratory
What does definitive host mean?
- Natural host for a disease
- EX: Dirofilaria immitis= dog
What is pathogenesis?
Development of morbid condition of a disease in question, start with infection and see how it spreads and what it affects
What does CDC stand for and where are they located?
- Center for disease control
- Vet: Ames, Iowa
- Human: Atlanta, Georgia
What is a parasite?
Living organism that lives at the expense of another organism called the host
What are symptoms?
- Signs of a disease that can be visualized with the naked eye
- EX: Vomiting
What are clinical signs?
- Signs of disease that can be deduced through laboratory test
- EX: Hematocrit
What is a fomite?
Inanimate object that can maintain the presence of a etiology so as to be passed along to another animal or person
What does prophylaxis mean?
Prevention of disease
What are 3 different diagnosis?
- 1) Differential
- 2) Tentative
- 3) Defenitive
What does differential diagnosis mean?
All of the diseases that it could be based on symptoms
What does a tentative diagnosis mean?
Most likely disease based on current history
What does a defenitive diagnosis mean?
Absolute identification of the etiology based on clinical signs
What is a peracute disease?
Acquisition of etiology and death within 24 hrs
What is a acute disease?
Disease can be severe and possibly deadly but within a longer time 48-72 hrs
What is a subacute disease?
Mild clinical signs like pyrexia and anorexia that doesnt defer the patient from a relatively normal behavior
What does subclinical mean?
No noted clinical signs but may show occasional symptom of nausea or diarrhea, animal acts normal
What does chronic mean?
Harbors etiology but never shows symptoms or clinical signs
What does zoonosis mean?
Disease of animals that may be transmitted to man under natural condition
What is epizootic?
Attacking many animals in any region at the same time, clears up and doesnt come back
What is enzootic?
Present in an animal community at all times, but occurring in only small number of cases, clear up and disease comes back time to time
3 main canine disease that cause enteric disease?
- 1) Canine parvo
- 2) Canine coronavirus
- 3) Canine rotavirus
What happened in 1967?
Canine parvovirus 1, called the minute virus in military dogs, closely related to bovine parvo
What are other names for Feline Panleukopenia?
- 1) Infectious feline enteritis
- 2) Feline distemper
What is the most common etiological agent of all animal bite wounds?
London, England during 19th century, Tropic flea rat eats Yersinia pestis causing the rat to vomit on the rat/human and host gets Y. pestis with flea and host both dying.
What does bubonic mean?
Enlarged submandibular lymph nodes
What is immunity?
Activities of the immune system
2 types of immunity
- 1) Non-specific immunity
- 2) specific immunity
4 types of non-specific immunity
- 1) Species resistance
- 2) Mechanical and chemical barriers
- 3) Inflammatory response
- 4) Interferon and complement
Refers to the genetic ability of a species to provide defense against certain pathogens
Mechanical and chemical barriers
- Prevent entry of microorganisms
- EX: Skin and mucous membranes
When a tissue is invaded by microorganism, cells release enzymes called mediators. Mediator enzymes attract wbc (basophils) which dilate the blood vessels and increase permeability to the vessels in the area. Neutrophils move through the cellular clefts into the tissues to phagocytize the microorganisms thus controlling the infection
Chemical that cells that are invaded produce, interferes with the ability of viruses to cause disease by preventing their replication within the host cell
Group of enzymes that is activated during infections. Binds to invading cell wall producing small holes in the membranes which results in rupture of the foreign cell before it can do damage to the host cell
