Eucalyptus and Colloidal Silver. Obtain two nutrient agar plates and using a permanent marker draw four quadrants on the bottom of each agar plate. Using a sterile pipet transfer 250 ml of E. coli broth to the middle of each petri dish and evenly spread bacterial culture around the agar plate. Cover and allow the culture to soak into agar for at east 15 minutes. Using sterile forceps‚ carefully place one filter disk from designated sample into the middle of each

Enumeration of Bacterial Contamination in Hamburger Meat from Unknown Sources C March 6‚ 2012 The importance of bacterial enumeration has become even more apparent in recent years due to the increasing numbers of harmful bacteria found in meat products. This process is the key to understanding the populations of microorganisms that contaminate the food supply. Much of the bacteria in meat has been shown to be resistant to multiple drugs; so disease-causing microbes

these micro-organisms were present and how widespread and abundant they were. Method: In the experiment‚ there were 3 environments in which agar plates were used to get bacteria and fungi. Environment No.1 was inside the lab with the laboratory air‚ environment No.2 was outside the lab in the open air and environment No.3 was taken from scalp scrapings from the students involved. In environment 1‚ 6 agar plates were produced. The 6 plates were separated into groups of 2. Each group of 2 was exposed

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

Introduction: Bacteria are microscopic‚ single-celled organisms. Their genetic information is encoded in one large chromosome. It can also be found in plasmids which are small circular pieces of DNA that contain important genetic information for the growth of bacteria. In nature‚ this information is often a gene that encodes a protein that will make the bacteria resistant to an antibiotic. The reason for this protein being made within the bacteria is because of how bacteria usually grow in the same

Investigating the Effects of Plant growth within Abstract This experiment was conducted to determine whether or not those plants can grow in low fertilized‚ less sun light and the control group. Each group had there own task of making sure that the plants were always water‚ each plant had the same amount of light on them. When the plants started to evolve each individual plant was measured of the height. Most of the plants grew faster than others but over the period the plants that grew faster

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

Bacterial Morphology MLT1 Task 11- Lab 2 Johnny Archuleta Western Governors University Question A and C answers. A wet mount stain is when a drop of water is placed onto the microscope slide. The water on the slide helps to support the organism and sample. The water fills the space between the cover slip and the slide. This action allows the light from the microscope to pass through the slide and the sample for better visualization of the organisms. A direct stain occurs when a charged

Disinfection‚ decontamination‚ disinfectant‚ antiseptic‚ sanitizer and antibiotic are another chemical agents that can used to affect on bacterial growth. Chemical methods involve the application of specific chemical agents which inhibit growth or kill microbes on the surface of skin. The determineing of an suitable
