Computation of Final Grade
- Final Grade (FG) for Lecture: FG = (1/2) [Midterm Grade (MTG)] + (1/2) [Final Term Grade (FTG)]
- Final Grade (FG) for Laboratory: FG = ½ Lab Assessment 1 + ½ Lab Assessment 2
- Combined final grade formulations depend on the unit allocation of Lecture and Laboratory.
Introduction to General Veterinary Pathology
- Focuses on providing a foundation for understanding disease mechanisms, classifications, diagnoses, treatments, monitoring disease progression, prognosis determination, and complications comprehension.
Key Definitions
- Infection: Tissue invasion by pathogenic organisms leading to disease.
- Infestation: Attack by parasites/organisms on the skin's surface.
- Pathogenicity: An organism's ability to produce disease.
- Prognosis: Expected outcome of a disease.
- Clinical Signs: Objective evidence of disease perceivable by veterinarians.
- Symptoms: Subjective evidence of disease indicated by altered bodily or mental states.
- Incubation Period: Time from cause action to disease manifestation.
Intrinsic Causes of Disease
- Determined factors beyond individual control, classified as:
- Genus: Specific diseases linked to a particular genus (e.g., hog cholera in pigs).
- Breed/Race: Certain breeds predisposed to diseases (e.g., dairy cattle and mastitis).
- Age: Younger animals susceptible to certain conditions (e.g., diarrhea; older animals to tumors).
- Sex: Reproductive disorders more common in females; specific conditions may vary by sex.
- Color: Certain cancers more prevalent in specific coat colors (e.g., squamous cell carcinoma in white cattle).
- Idiosyncrasy: Unique individual reactions to substances (e.g., drug reactions).
Extrinsic Causes of Disease
- External etiological factors influencing disease occurrence, classified into:
- Physical Causes: Environmental impacts leading to disease.
- Chemical Causes: Toxins from various sources (plant, microbial, etc.).
- Biological Causes: Pathogens such as viruses, bacteria, fungi, and parasites.
- Nutritional Causes: Deficiencies in key vitamins leading to specific disorders (e.g., Vitamin D causing rickets).
Types of Nutritional Deficiencies and Their Effects
- Vitamin A: Causes squamous metaplasia and blindness.
- Vitamin D: Linked to rickets in young and osteomalacia in adults.
- Vitamin E: Associated with white muscle disease and encephalomalacia in chicks.
- Vitamin K: Responsible for bleeding disorders.
- Thiamine: Leads to Chastek paralysis in some mammals.
- Riboflavin: Causes curled toe paralysis in chicks.
- Niacin: Associated with black tongue/pellagra in dogs.
- Folate and Cyanocobalamin: Linked to anemia.
- Vitamin C: Causes scurvy in guinea pigs.
Congenital Causes
- Includes conditions such as umbilical hernia and syndactylia.
