Chapter 50.7, Problem 2LO
Summary Introduction
To describe: How the immune system has affected the pathogen’s evolution.
Introduction: Any pathogenic microbe must overcome both specific and nonspecific immune systems of the host to establish and cause an infection. Several pathogens modify their surface antigens to prevent detection by the immune system. This kind of natural selection enables the continuous survival of pathogens with the modified surface antigens. Universally, the influenza virus is considered an example of a virus that modifies its surface antigens frequently to prevent the identification and destruction by the immune system.

What kind of selection is this an example of and why?arrow_forwardEpidemiologist rely on a set of standard study designs to understand the distribution of 'diseases' and what factors are associated with the presence or absence of disease. Ultimately, the goal is to identify the 'causes' of disease in order to prevent the disease in the future. In modern epidemiology, disease is defined broadly, and can range from infectious diseases (e.g., malaria, HIV), chronic diseases (e.g., heart attack, stroke, diabetes), injuries (e.g., car accidents, homicide), or even social conditions (e.g., poverty). Exposures too may be defined as anything proposed as a potential cause (or correlate) of the disease. For this exercise, briefly outline a hypothetical study to investigate a potential exposure/disease relationship. You may draw on your own experience or choose a topic that is of interest to you.
