Lesson 2: The One-Step Growth Curve
The one-step growth curve, developed by Max Delbriick and Emory Ellis (1939) using the Escherichia coli-T4 bacteriophage system, marks the start of modern bacteriophage research. Viral replication is often analyzed…
Lesson 4: Characteristics of Viral RNA genomes
Viral RNA genomes have distinct characteristics that influence their replication, diversity, and interaction with host cells. 1. Genome Polarity (Sense) Can be single-stranded (ss) or double-stranded (ds) and can occur…
Lesson 2: Control of Viral Infections
Control of viral infections involves strategies aimed at preventing the spread of viruses, reducing the severity of disease, and ultimately eliminating the virus from the host or environment. 1. Vaccination…
Lesson 1: Epidemiology of viral infections
Epidemiology is the study of the distribution, dynamics, and determinants of diseases in populations. Epidemiology includes: Mechanisms of viral transmission Risk factors for infection, Population size required for virus transmission…
Lesson 3: Adaptive immune response to viral infections
The adaptive immune response to viral infections is a highly specific and targeted defense mechanism that involves the activation of immune cells and the production of antibodies to eliminate the…
Lesson 2: Innate immune response to viral infections
Viral innate immunity is the first line of defense the body employs to recognize and combat viral infections. It is a rapid, nonspecific response that provides immediate protection against a…
