Case Study Report for Unknown #49 A new school for girls was opened in a larger village in Northern Pakistan‚ and the teachers were proud to have convinced many families in the surrounding villages to allow their daughters a basic education. The school was a success‚ and the 6-10 year olds girls quickly learned how to read and write and were even instructed in the sciences. However‚ 2 weeks before summer break‚ many of the girls and the teacher developed breathing problems that included severe coughing

Isolation and Identification of Staphylococcus aureus and epidermidis Wendy Heck Bio 175: General Microbiology Fall 2012-11-21 Staphylococcus aureus is the most pathogenic for humans and Staphylococcus epidermidis is part of the normal flora and is of low pathogenicity. Staphylococcus epidermidis and Staphylococcus aureus are two medically important species of bacteria. A culture from the nose and throat was taken to perform whether or not Staphylococcus epidermidis or Staphylococcus aureus

1. Describe the major differences between gram positive and gram negative bacteria cell walls. The gram negative bacteria cell wall is a thin peptidoglycan layer and an outer cell membrane with a lipopolysaccharide layer. The gram positive bacteria cell wall is a single thick peptidoglycan layer. This wall forms in a mesh like formation of three layers of alternating material. 2. From the procedure that you have carried out‚do you feel that the Gram positive stain is a simple procedure? No‚

Lab Report Abstract: The purpose of this lab was to see how magnesium reacts with oxygen. This reaction must be forced with heat. As magnesium changes to magnesium oxide the mass increased. Procedure: 1. Set up the stand and bunsen burne. 2. Go to crucible heat oven to obtain a crucible. 3. Weigh the crucible and lids mass. 4. Break up the magnesium ribbon on the crucible and weigh the mass of the magnesium‚ crucible‚ and lid. 5. Place the crucible on the ring stand over the flame. Allow

David Kennedy Bio 210 Lab Report 1 10/11/13 Microbial Growth Background Information: This lab was conducted in order to understand basic differences among differential and selective media‚ while recognizing how each media is used to isolate and identify microorganisms (Wistreich‚ 2003). The first microorganism analyzed was Staphylococcus epidermidis. This organism is gram-positive‚ single celled‚ arranged in grape-like clusters‚ and cocci in shape (Bukhari‚ 2004). S. epidermidis is approximately
