Bacterial Morphology Demonica Britt Microbiology DL1 March 23‚ 2013 Abstract This lab was performed to identify and familiarize with a microscope while precisely observing various bacterial shapes and their arrangements in different types of specimens of bacteria. The microscope parts and capabilities were clearly identified and used successfully and the bacteria were clearly illustrated showing the bacterial shapes and arrangements with all the appropriate magnification being utilized.

Dr. Annie Cu Gallardo BSE-Biological Sciences III-3 Microbiology (Lecture) Microbiology Written Report REPORT NO. 1 Prokaryotes: Bacteria Most of us have been conditioned to think of bacteria as invisible‚ potentially harmful little creatures. Actually‚ relatively few species of bacteria cause disease in humans‚ animals‚ plants‚ or any other organisms. In fact‚ all organisms made up of eukaryotic cells probably evolved from bacteria-like organisms‚ which were some

EC Assignment 1) First‚ the urine sample container should be labeled accordingly. Urine samples and transport containers should be free of any particles or anything that may interfere with the sample. The sample should be in a secure container with a leak resistant lid; this will also prevent exposure to the person handling the sample while also protecting the sample from being contaminated. It is important to not reuse any specimen container to insure that the sample is in a sterile environment

Major concepts to review for Exam 1: 1.) know the elements of life – and how the reduction and oxidative of some of these drive bioenergetics 2.) Know the general time line for biology and evolution on the Earth; What major events altered evolution especially in terms of microbially driven changes 3.) Carl Woese – what did he contribute? What kind of biological molecules are best to generate phylogenetic trees‚ and why? How does this compare to enzymes? 4.) What defines a species (formal definitions)
