These slides are not presented in any particular order. Name this Procedure Identify the two types of bacteria present by shape and gram stain. In a gram stain what is the primary stain? The mordant? The counterstain? How does this differ from a simple stain? Identify the shape and gram stain of the bacteria present in this gram stain. Identify the shape and gram stain of the bacteria pictured. Think on this one! Name the gram stain and shape of the bacteria pictured. Name the genus of the

BIOSC 0050 Oct. 9‚ 2012 Dead or Alive? (Week 2) Post-Lab Assignment Results: The results of the Feulgen’s Schiff’s Stain test are that samples ALV-188-23 and ALV-843-20 turned magenta and samples ALV-882-21 and ALV-694-02 did not turn magenta. The result of the tetrazolium test is that all four of the samples did not turn pink. We were not able to conduct the detailed analysis of cultured plates with growth‚ so not results are available for this test. Discussion: For the Feulgen’s/Schiff’s

Introduction By examining blood smear by microscopy it can detect infections whether they are viral or bacterial. Blood smears are examined by looking at the white and red blood cells appearances. The aim of the experiment is to compare a normal blood smear and its pathological features to those with an infection or abnormality by the use of microscopy looking at the cells involved with blood. A normal blood smear would contain 3 to 4 white blood cells per field in microscopy. If there is an

Amoeba a. nucleus- dark center of the cell b. food vacuole- They feed by taking nutrients into the cell by diffusion and packaging it into (clear circles spread throughout the cell) c. pseudopod- “false foot”; the motility results from the streaming of the protoplasm that forms the process 2.

Del Mundo‚ Layah Basella rubra as a biological stain Experimental The alugbati extract turned out to be favorable stain for plant nuclei and organelles especially for Hydrilla verticillata and as substitute for crystal violet or safranin in Gram staining. The extract stained the bacteria red-orange and the plant nuclei‚ and the cytoplasm red and light pink‚ respectively. The study is limited to the ability of Basella rubra (alugbati) to be used as a biological stain 2011 Gel-O-Fury- Saavedra‚ Ralph

Microbiology UNKNOWN LAB REPORT Kateryna Petrakova INTRODUCTION Microorganisms cause a great amount of diseases. For healthcare providers it is very important to be aware of what organisms are pathogenic and cause a disease and‚ therefore‚ to find an appropriate treatment. Different microorganisms require various environments in order to replicate and to become dangerous for a person’s health. An integral part of any medical treatment is to be able to recognize and

First‚ the matting was placed on the four slides‚ cover-slips as well as the container of blood on top. Blood containers are in dropper bottles. Number each slide with a wax pencil. A drop of blood was placed on a slide and numbered it slide #1. Slide #1: 1. With the wooden applicator stick‚ dip the end into the blood and place a tiny drop onto slide #1 and put cover slip over it. Slide#2 1. Place 1 drop of 0.9% NaCl with the drop of blood (use the filter paper to absorb excess liquid). 2.

Two different types of procedures were carried out over the course of this experiment: tube inoculation and plate inoculation. We started with plate preparation. Three different lysogeny broth‚ or LB‚ agar plates were prepared for E. coli growth every other week: a control where water was used‚ one for triclosan‚ and one for streptomycin. Using an inoculation loop‚ E. coli was transferred from the test tube to the agar plate. This was done to each plate twice‚ creating a grid-like pattern of bacteria

Today you’re going to learn two things. Firstly‚ Agrimonia is a genus of a species of plant that usually lives for a maximum of 2 years and it has a history of medicinal uses ranging from treating weariness to ailments for various organs; some believed that if you placed stems of a particular species of Agrimony on someone’s head‚ they would fall asleep instantly and would not wake up until the plant was removed. Secondly‚ Agrimonia is a crust punk band from Sweden featuring members of At the Gates
