Lab Experiment 2. The Gram Stain. A one lab session experiment. In most microbiological staining procedures, the bacteria are first fixed to the slide by the heat fixed smear. In this procedure living, potentially pathogenic bacteria are smeared on the glass slide and allowed to dry. Then the slide is heated so that the bacteria
29 Feb 2012 MW 3:45-5:00. Gram Stain Report. Introduction. The purpose of this experiment is to determine the shape and Gram stain of the bacteria under a microscope. The reason for staining bacteria is due to the fact that most bacteria are transparent and cannot be seen through the microscope. The Gram stain is a

Demonstrate mastery of techniques and information covered in this laboratory on the post test. ASSIGNMENT. 1. De?ne BACKGROUND. The Gram stain is the premier differential stain of bacteriology, developed by. Christian Gram in 1884. . Report for Microbiology Lab 4 Date Name. Smear Preparation and Gram Stain.
INTRODUCTION Gram staining is the most essential and universally used staining technique in bacteriology laboratory. Gram-staining was firstly introduced by Cristian Gram in 1883.This method is used to distinguish between gram positive and gram-negative bacteria which have consistent differences in their cell walls.
The gram stain, originally developed in 1884 by Christian Gram, is probably the most important procedure in all of microbiology. It has to be one of the most repeated procedures done in any lab. Gram was actually using dyes on human cells, and found that bacteria preferentially bind some dyes. The Gram stain is a
A. Gram Stain. The previous lab introduced simple staining techniques that enable microbiologists to observe the morphological characteristics of bacteria. Although simple stains are useful, they do not reveal details about the bacteria other than morphology and arrangement. The Gram stain is a differential stain commonly
Lab Report #1. Exercise 7B Gram Staining an Unknown. The report is worth 100 points. It should be 2-3 pages long, typed, 12-point font and double-spaced. It should contain an introduction, procedure (materials and methods), results, discussion and literature cited. Label each section in your report. You must cite.
