★ AQA Specification Reference: - 3.2.4 Cell recognition and the immune system. Structure of the human immunodeficiency virus (HIV) and its replication in helper T cells.
★ CIE Specification Reference: - 10 Infectious disease: b) state the name and type of causative organism (pathogen) of each of the following diseases: cholera, malaria, tuberculosis (TB), HIV/AIDS, smallpox and measles (detailed knowledge of structure is not required. c) explain how cholera, measles, malaria, TB and HIV/AIDS are transmitted d) discuss the biological, social and economic factors that need to be considered in the prevention and control of cholera, measles, malaria, TB and HIV/AIDS (a detailed study of the life cycle of the malarial parasite is not required). 11 Immunity: Not HIV Specific - useful for: c) describe and explain the significance of the increase in white blood cell count in humans with infectious diseases.
★ Edexcel (Biology A – Salters-Nuffield) Specification Reference: - Topic 6: Immunity, Infection and Forensics: 6.6 Understand how Mycobacterium tuberculosis (TB) and Human Immunodeficiency Virus (HIV) infect human cells, causing a sequence of symptoms that may result in death.
★ Edexcel (Biology B) Specification Reference: - Topic 6: Microbiology and Pathogens: Not HIV Specific but useful for: 6.7 Response to infection.
★ OCR (Biology A) Specification Reference: -4.1.1 Communicable diseases, disease prevention and the immune system: Learners should be able to demonstrate and apply their knowledge and understanding of: (a) the different types of pathogen that can cause communicable diseases in plants and animals. To include, viruses – HIV/AIDS (human).
★ OCR (Biology B) Specification Reference: - 3.2.1 Pathogenic microorganisms: Learners should be able to demonstrate and apply their knowledge and understanding of: how pathogens (including bacteria, viruses and fungi) cause communicable disease. The causes, means of transmission, symptoms and the principal treatment of tuberculosis (TB) and HIV/AIDS. To include an outline of the general mechanisms of pathogenicity by bacteria (toxin production), viruses (taking over cell metabolism) and fungi (enzyme secretion). the structure of the Human Immunodeficiency Virus (HIV). To include the use of diagrams showing the location of enzymes and the nature of the genetic material.
★ WJEC Specification Reference: -Immunology and Disease: Not HIV Specific but useful for:
1. Disease: - Learners should be able to demonstrate and apply their knowledge and understanding of: (d) the relationship between the pathogenicity of viruses and their mode of reproduction.
