Identification and Diagnosis of Unknown Enteric Bacteria in an Infected Patient Using an Enteropluritube Brooke Addario 2/16/2015 BIO 488C - Section J TA – Jacob Karsten Introduction: Enteric bacteria are members of the Enterobacteriaceae family of microorganisms. These gram negative‚ rod shaped‚ facultative anaerobes are found in the intestinal tracts of humans and animals. Enteric bacteria can be pathogenic; however‚ they are also a normal part of human bacterial flora and are therefore

ISOLATION OF INDIVIDUAL BACTERIAL COLONIES ON SOLID MEDIA Robert Koch developed a method for isolating pure cultures on solid media in 1883. To this end he added agar (a solidifying agent) to liquid nutrient broth; the nutrient broth supports the growth of a wide variety of microorganisms while the agar provides a solid substrate on which bacteria can be mechanically diluted and therefore isolated as independent colonies representing different bacterial species. The isolation of independent bacterial

Introduction The purpose of this project was to detect which organism we had in our unknown mixed culture tube by running a series of experiments to detect which specific Gram negative organism we had. To detect your gram positive from the mixed culture was given as extra credit points also. A Gram stain was performed and isolation streak plate in order to isolate and observe the unknown organism. Before the series of test‚ a dichotomous key had to be written up in order to know what steps

LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured

While observing a couple catheter placements‚ I realized the technicians do not treat catheter placements as an aseptic procedure. The technicians don’t wear gloves and don’t scrub as religiously as we were taught in school. Placing a catheter into the bloodstream without wearing gloves or scrubbing the area correctly could introduce bacteria into the bloodstream‚ resulting in nosocomial septicemia. Another thing I was made aware of during this day‚ the rules for the hospital has changed and the

Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist

The prediction for this lab‚ is that the unwashed lettuce and the opened milk will have the most bacteria growth. All results are meticulous within the expectations of the lab report. II. Purpose The principle of this experiment is to have a thorough perceptive of: • Culture washed and unwashed lettuce on agar plate. • Culture fresh and opened
