Microbiology with Diseases by Body System Chapter 1

-eukaryotic membrane bound nucleus -obtain food from other organisms -posses cell walls - fungi -Unicellular lack nuclei -much smaller than eukaryotes -found everywhere there is sufficient moisture -reproduce asexually one contains peptidoglycan, one composed of polymers other then peptidoglycan - contains bacteria, don't contain archaea bacteria and archaea (Antiseptic technique) first to use chemicals to prevent bacterial infections during surgery - Joseph Lister 1. Which of the following microorganisms are not eukaryotic? a. bacteria b. yeasts c. molds d. protozoa - Bacteria 1.) suspected causative agent must be found in every case of the disease, and be absent from healthy hosts. 2.) agent must be isolated and grown outside the host. 3.) Agent is introduced to a healthy suspectible host, host should get disease. 4.) the same agent must be found in the diseased experimental host. - KOCHS POSTULATES 2.
