Study Notes

Manifestation of Clinical Diseases

A disease is an inability to perform physiological functions at normal levels, even with adequate nutrition and environment.
Systemic alterations are common during disease processes.
Infections can manifest locally or systemically, gradually developing over days to years.
Infections can affect multiple organs, and symptoms may resolve with treatment.

Systemic States

Hypothermia: Lower than normal body temperature, a major cause of neonatal mortality and morbidity. Causes include excessive heat loss (exposure to cold) and insufficient heat production (low energy reserves, poor feed intake). It can also be a symptom of other diseases.
Hyperthermia (Heat Stroke/Heat Exhaustion): Increased core body temperature often due to exposure to high environmental temperatures or strenuous exercise. Other contributing factors include neurogenic issues, dehydration, excessive activity, and various poisonings.

Fever Types

Septic Fever: Infection with bacteria, viruses, protozoa, or fungi, causing localized or systemic issues (bacteremia, endocarditis, septicemia).
Aseptic Fever: Fever associated with aseptic wounds, likely due to leukocyte breakdown or tissue damage.
Chemical Fever: Fever caused by substances like foreign proteins or dinitrophenols.
Surgical Fever: Fever due to tissue breakdown and inflammation (muscle damage, hemolytic crises, infarctions, neoplasms).

Forms of Fever

Transient: Body temperature fluctuates around normal during the day.
Sustained/Continuous: Little change in temperature over a 24-hour period (not exceeding 1°C variation).
Remittent: Temperature fluctuates but never reaches normal levels.
Intermittent: Recurring fever attacks with periods of normal temperature in between.
Atypical: Irregular temperature variations.

Septicemia and Viremia

Septicemia: Acute invasion of the bloodstream by pathogenic bacteria, often with septic shock and possible localization in organs.
Bacteremia: Bacteria in the bloodstream, not associated with clinical signs and not necessarily causing sepsis or shock.
Viremia: Pathogenic viruses in the bloodstream potentially affecting tissues.

Toxemia and Endotoxemia

Toxemia: Widespread host response to toxins from bacteria or tissue damage; detectable toxins in the blood are crucial for diagnosis.
Two classifications of toxins are: 1) Antigenic toxins which are often produced by bacteria and helminth parasites and stimulate antibody production and 2) Metabolic toxin toxins that result from incomplete elimination or abnormal metabolism of body materials

Fever (Pyrexia)

Increased body temperature independent of environmental conditions.
A combination of hyperthermia and infection/inflammation, rising from a higher temperature setpoint by the body.
Mediated by endogenous pyrogens (produced by immune cells) and exogenous pyrogens (bacteria, viruses, toxins).

Pain (Nociception)

Pain is a distressing sensation resulting from stimulation of specific nerve endings. There are three types: cutaneous, visceral, and somatic.

Stress

A systemic state resulting from long-term exposure to stressors.
May lead to psychosomatic diseases, increased susceptibility to infections, and decreased productivity in animals.

Localized Infections

Abscess: Localized collection of pus, often occurring in response to infection or foreign material.
