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 The science of microbiology is all about microorganisms‚ what they do and how they work. Microorganisms are ubiquitous‚ and are a very important part of life everywhere since they have been around for billions of years. The two main themes associated with microbiology are (1) having an understanding of the nature and function of the microbial world‚ and (2) being able to apply that understanding of the microbial world so that the benefits to the Earth and humans are known(6).

The purpose of the following study is to determine where the two unknown bacteria acquired in Microbiology lab should be classified in regards to temperature‚ pH level‚ and osmoregularity. It is important to classify bacteria in order to identify them. Identification of bacteria is important because they are not only useful but potentially dangerous as well. The identification of bacteria can lead to breakthroughs in healthcare regarding treatment of old and new diseases alike. Identifying bacteria

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 and how
