Medical assistant Assists physician Obtains specimens Prepares specimens for direct examination Prepares specimens for transportation to reference laboratory If office has a POL, performs microbiologic procedures 15- How Microorganisms Cause Disease Cause disease in variety of ways Use nutrients needed by cells and tissues Damage cells directly Produce toxins May remain localized
