Microbiology Study Guide Chapters 1-6 Chapter 1 Main Themes of Microbiology Microorganisms Most are not Pathogens Prokaryotic-no nucleus or organelles Very simplistic—like bacteria Eukaryotic-has nucleus and organelles like mitochondria Includes fungus‚ and animals Acellular-not even a complete cell Includes viruses and prions like those that cause Mad Cow disease Six main types of microorganisms Bacterium (prokaryotic) Fungus (eukaryotic) Algae (eukaryotic) Virus (acellular)

Introduction The working hypothesis being tested is if any of the three products; Scope Mouthwash (Scope)‚ LISTERINE® Antiseptic Mouthwash (Listerine)‚ Bactine Original First Aid Liquid (Bactine)‚ and Povidone-Iodine Solution‚ 10% Topical Microbicide Antiseptic (Iodine) are an appropriate antiseptic to can kill a sample bacterial contaminant found in the local environment‚ and if so‚ which is the most effective? The purpose of this experiment is to determine the antibacterial effectiveness of Scope

walls of bacteria‚ a Gram stain determines what kind of bacterium the cell is. The Gram stain works by creating a purple dye that either attaches or fails to attach to the peptidoglycan either found or not found on the cell wall of the cell. Gram-positive bacteria are cells that have a large amount of peptidoglycan in their cell wall‚ and those that are Gram-negative have an extra cell wall that does not allow the stain to set on the cell wall (Vidyasagar). In addition to staining the cell‚ the identification

Chapter 1 Cell Theory- in the 18th century‚ two scientists came up with the cell theory. Schleiden and Schwen. 3 corollaries of the cell theory: -all cells are alike in chemical composition -all cells store and process information in the same way -all cells arise from other cell through cell division 5 types of different Microscopes 1. Light Microscope- produces 2-D image Direct descendants of Hooks scope> take two lenses to a light source> used this to magnify images up to 1‚000 fold.

survivability in artificial gastric juice ABSTRACT: Two probiotic drinks were investigated in vitro to test their ability to survive acidic conditions and their probiotic factors. Both the products: Actimel and Yakult contain gram-positive bacteria‚ but Actimel also has a gram-negative bacteria. The ability to survive was investigated by adding artificial gastric juice to the products and incubating at different times. Actimel and Yakult were both able to survive the gastric juice. Actimel produced

Chapter 25 Pre-Test Question 1 Part A Miller and Urey’s experiments that attempted to recreate conditions on early Earth were significant because _____. Hint 1. They gave credence to the idea of abiotic synthesis. ANSWER: they showed how polymers could form spontaneously on a clay substrate they produced the first protocells they showed how radiometric dating could be used to give the absolute ages of rocks and fossils proved the endosymbiotic theory they showed that organic

Statement of Purpose Some people view biological science as an area of science which is boring; requiring intensive memorization and less logical reasoning. True to my heart‚ my view towards biological science was no difference! It was not before my higher secondary school classes when I first realized the beauty of this scientific arena. I had my first glimpse at molecular biology then. But that brief introduction to molecular biology was enough to compel me to the idea that I want to spend my

We report 3 rare cases of post-cardiac surgery wound infection attributed to Mycoplasma hominis and provide a summary of the clinical characteristics of these infections. The path of infection by Mycoplasma hominis is notably surreptitious‚ rendering its detection and treatment challenging. Some researchers have proposed that invasive medical procedures‚ notably catheterization‚ can facilitate the entry of Mycoplasma hominis into the bloodstream and its subsequent colonization at the site of surgery

A study conducted by Krawitz and colleagues in 2011 where the black elderberry was seen as a beneficial herbal supplement for treating influenza and bacterial infection through the enhancement of cytokine production and T cell activation. Sambucus nigra contains anthocyanins‚ which is a bioactive compound that responsible for colors such as red‚ purple‚ or blue. In addition‚ it also provides various health benefits. Studies of anthocyanins for animal and in vitro reduced necrotic and apoptotic cell
