BACTERIAL MENINGITIS BY JAY DOMANTAY JAY DOMANTAY ANATOMY 151 HERBERT MAY 11‚ 2009 BACTERIAL MENINGITIS A bacterial infection of blood poisoning in the meninges called bacterial meningitis affects toddlers‚ adolescents and young adults. The infection strikes nearly 3‚000 Americans each year‚ and 10 to 12% of those infected will die. Among those who survive‚ approximately 20 % live with permanent disabilities‚ such as brain damage‚ kidney disease‚ hearing loss or loss of limbs.(“Prevention

Spontaneous bacterial peritonitis: an acute bacterial infection of ascites fluid. Although a bacterial infection the infecting agent is not easily identified. Spontaneous bacterial peritonitis is commonly seen in patients receiving peritoneal dialysis due to contamination of dialysate. Signs and symptoms: a wide range of symptoms including diarrhea‚ worsening encephalopathy‚ ascites that do not improve following administration of diuretic medication‚ worsening or new renal failure and ileus

aureus (Staphylococcus aureus ATCC 25923‚ Gram-positive cocci‚ in purple) andEscherichia coli (Escherichia coli ATCC 11775‚ Gram-negative bacilli‚ in red)‚ the most common Gram stain reference bacteria Gram staining (or Gram’s method) is a method of differentiating bacterial species into two large groups (Gram-positive and Gram-negative). The name comes from its inventor‚ Hans Christian Gram. Gram staining differentiates bacteria by the chemical and physical properties of their cell walls by detecting peptidoglycan

to carry nutrients through the cells and make them into useful substances for the cell to utilize. What is the typical size difference between animal cells and bacterial cells? The typical size difference between animal cells and bacterial cells is that animal cells normally are significantly larger. Another difference is that bacterial cell contains a plasmid‚ against the chromosomes that animals possess. Part B: The Gram Stain This procedure is used to separate what two types of bacteria? Gram

The identification of an unknown bacterial environmental isolate through a series of morphological‚ physiological and differential exercises. The purpose of the environmental isolate report is to learn what is necessary in order to take an unknown environmental isolate (EI) and identify it. This was achieved through a series of exercises that provided information on the morphological‚ physiological and biochemical traits of the EI which were then compiled and interpreted in order to make a presumptive

Atlas Sections In your Lab Atlas you will need to read Section 5: Bacterial Cellular Morphology and Simple Stains and Section 6: Bacterial Cell Structures and Differential Stains and then answer the following questions: 2. What is the third important feature of microscopy? Why? Third important feature of microscopy is contrast. To be visible‚ the specimen

conjunctivitis can occur in one or two of a person’s eyes. It tends to cause a watery discharge while conjunctivitis caused by bacteria causes a thicker discharge. Both are transmitted to another eye in the discharge. Children are primarily affected by bacterial conjunctivitis‚ possibly because it is more transferable in a location like school. People are at a higher risk of developing conjunctivitis if they use contacts. Those who come in

Alyse Rose Microbiology Lab Bacterial Unknown March 25‚ 2013 Bacterial Unknown Report Each student was given an unknown bacteria to figure out. I was given the unknown bacteria S38. Everybody is supposed to do all sorts of test to identify the bacteria. The first thing I did was smear my bacteria on a liquid medium. I then proceeded to incubate the medium for 24-48 hours. 1. GRAM STAIN The next step I took in finding my unknown bacteria was to gram stain it. This is used to differentiate

This lab experiment serves as a model for community succession using bacterial colonies as the model. A bacterial colony grows from a single bacterium and is composed of millions of cells. Each colony has distinctive colony morphology: size‚ shape‚ color‚ consistency‚ and color. Community succession is a phenomenon observed in the organizational hierarchy of all living organisms. Community succession is not limited to bacterial colonies‚ but spans the entire community of life. As the community
