Objectives
 Discuss the history of disease control
 Discuss infectious disease control
 Discuss non-infectious disease control
 Describe the roles of the government
agencies that deal with disease control
 Discuss practices to foster health and wellbeing of animals
History
 Problems change with time



Brucellosis
Tuberculosis
Foot and mouth disease
 Types of disease



Emerging diseases
Endemic diseases
Foreign diseases
Infectious Diseases
 Infectious disease

Caused by a pathogen that can invade (infect)
and then multiply in a susceptible animal
 Pathogens





Bacteria
Protozoa
Viruses
Fungi
Rickettsia
 In short

These organisms enter the body of
susceptible animals and cause an illness in
that animal
 Concern

Movement of animals introduces these
pathogens into susceptible populations
 US constantly on look out



TAHC
USDA-APHIS
USDA-VS
Non-Infectious Diseases
 Non-infectious disease

Caused by toxins (chemical poisoning) or by
malfunctioning of the body (as nutritional
disorders)
 Result of environmental or behavioral
changes
 In domestic populations
 Infectious problems reduced
 Disease
 Non-infectious problems increased
 Cancer
 Heart disease
 Control
 Eat healthier foods
 Smoke less
 Get more exercise
Agency Roles
 Both state and federal agencies involved
 Animals
 State
 Texas Animal Health Commission (TAHC)
 Federal
 USDA-APHIS
 People
 State
 Texas Department of State Health Services
 Federal
 United States Department of Health and Human
Services
 Zoonotic

Disease that is shared between animals and
people




Rabies
West nile virus
Anthrax
Animal and human agencies work together in
disease outbreaks
 Sentinel animals

See problems in these animals before see in
people
Health and Well-Being
 Preventive health management



Vaccinate
Biosecurity
Cooperation between state and federal
agencies
 Preventive measures







Identify reservoirs through surveillance
Prevent exposure
Develop immunity
Provide good nutrition
Provide adequate physical activity
Develop optimum environmental conditions
Develop selection and breeding programs
