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

Unknown Bacteria Lab Report Introduction The purpose to this lab was to identify an unknown bacteria from a mixed culture provided to us by our instructor. This study was done by applying all of the methods that have been instructed on thus far in microbiology laboratory class. Each test performed‚ provided us with some key information about the unknown organism in question and how the bacteria function. Over a two week period‚ eight prepared types of test media were provided to identify

UNKNOW BACTERIA LAB REPORT UNKNOWN 36 Introduction The purpose of this lab was to identify two unknown bacteria from a mixed culture. The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria can help treat a patient by knowing the contributing source of a disease. Also knowledge of different bacteria helped others

There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics to other purposes such as knowing the exact microorganism has to be used to make certain foods. This experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by the lab instructor. The methods that

Determining an Unknown Through Deferential Stains and Biochemical Tests Introduction There are many reasons for knowing the identity of microorganisms. The reasons range from knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification
