1. Mariana’s microbiology results have led to the ruling out of any urinary tract infection (UTI), Gastroenteritis and malnutrition. The results show that her red and white cell count are within the normal range and also the epithelial cells found in the urine sample are of a moderate amount and there were no significant bacterial growth. Abnormalities in this results would have indicated to a UTI but the results were normal. According to Roche (2011), presence of bacteria, in addition to a…

3 coats of polyurethane with a applicator made of lambs wool, and sanding between each coat. After 3 days, the floors should be fully cured. If you have stained the floors prior to applying polyurethane, know that applying polyurethane before the stain had dried can cause discoloration. Use the services of East Texas Floor Care if you need help caring for your hardwood floors. http://www.dummies.com/home-garden/flooring/how-to-fix-scratches-in-hardwood-floors/…

“Blood is one of the most significant and frequently encountered types of evidence associated with the Forensic Investigative of death and violent crimes” (James, Kish, and Sutton, 2005 p. 1). A Bloodstain Pattern Analysis is called when bloodstains are found at a violent crime scene. The Bloodstain Pattern Analysis discipline has been in existence for a long time, as early as the late 1800’s. “Bloodstain Pattern Analysis focuses on the analysis of the size, shape, and distribution of…

L.B. Agar Lysogeny broth (LB), a nutritionally rich medium, is primarily used for the growth of bacteria. The abbreviation is commonly taken to mean Luria broth, Lennox broth, or Luria-Bertani medium. According to its creator Giuseppe Bertani, the abbreviation LB was actually intended to stand for lysogeny broth (1). The formula of the LB medium was published in 1951 and continues to be the most common media used today (2). There are several common formulas of LB. Although they are different,…

These essential parts of the body are small, pointy, round, and help chew food. What are they? Teeth! Teeth come in many shapes, many sizes, and unfortunately, many colors.

and decided what specific primary antibodies, secondary antibodies, and nuclear stains we will be using. Thursday: On Thursday, Maggie was unable to come into the lab, she continued her literature search. Friday: On Friday, we spent the morning with Jamie at the imaging center taking images of the Bartonella samples she prepared a few weeks. She taught us how to calibrate the microscope for specific antibodies and stains, and how to identify Bartonella and other cell types in tissue samples.…

week we performed a differential staining to determine whether our unknown has a gram-negative envelope which stains red or gram positive envelope which stains blue. Gram-negative microorganisms stain red because of their inability to bind crystal violet and their ability to bind the safranin. Gram-positive microorganism, however, stains blue due to their ability to retain the primary stain, crystal violet. I determined my unknown sample to be a gram-negative microorganism. After viewing the…

In order to determine the sequence of events that occurred at a crime scene it is important to be able to determine and identify certain bodily fluids versus non-human substances. Based on the location of the biological evidence and its DNA can provide crucial information about the crime scene, its victim, and the suspect(s). These tests divided between presumptive and confirmatory testing. Blood evidence is the most common type bodily fluid found at a crime scene. Presumptive testing at the…

Afterward the bibulous paper is removed and the specimen is rinsed with DI water before being counterstained with safranin. Because of the endospore layer, endospore staining requires a longer period of time for the specimen to be stain and heat is used to drive the stain into the cells. The endospore layer also help retain the dye even after decolorized with DI water. Contrary, the malachite green will be washed of the cells without an endospore and take up the counterstain more easily making…
