Biology was fascinated me tremendously particularly when I was introduced to field of microbiology. I used to wonder how these primitive microbes grow and communicate with each other. Theoretical knowledge of microbiology grabbed my attention and made me curious about these tiny microbes which we cannot be seen through our naked eyes. Therefore I decided to pursue my higher studies and specialisation in microbiology. I started my graduation

TITLE Lab #4 Soil –vs- Water Microbiology INTRODUCTION There are 4 learning goals for this lab: 1. Collect samples and compile data from at least 2 sources (soil; water) of your choice. 2. Identify at least 2 Prokaryotes (bacteria) and 2 Eukaryotes (fungus) in your samples. 3. Research the importance of bacteria and fungus to Earth in a non-medical context. 4. Compile a high-quality‚ 3+ resource (excluding the lab worksheet)‚ MLA-cited in-text laboratory report using the scientific method

slant‚ with bubbles and no black precipitate. These conclusions identified the unknown organism as Serratia marcescens. Introduction The purpose of this paper was to inform the reader of the importance of microbiology in the world today. Microbiology studies the behavior of microorganisms and teaches students about the effect of bacteria‚ fungi‚ viruses‚ algae‚ and yeast on living things. Studying these microorganisms gives insight to the spread of different diseases

Labset Four Worksheet 1. Define the term “selectively toxic.” Why is it an important feature of antimicrobial agents? A substance or drug is selectively toxic if the agent used in it is able to kill the microorganism that it is meant to without harm to the host that has taken the drug. This is very important to microbial agents in that it enables these agents to inhibit a microorganism by interacting with microbial functions or structures different from those of the host; thereby showing little

Introduction to Microbiology – Case Study 1 Kristen Alejos You are working as an emergency room nurse in Topeka when a mother brings in her 8 year old son because of severe‚ bloody diarrhea. When questioned‚ the boy said that it hurts when he goes to the bathroom and his mother said he had vomited in the previous two days. When asked about their previous movements‚ the mother and son both mentioned a backyard barbeque that had taken place 6 days earlier. The boy complained that his mother
