1995 Del Mundo‚ Layah Basella rubra as a biological stain Experimental The alugbati extract turned out to be favorable stain for plant nuclei and organelles especially for Hydrilla verticillata and as substitute for crystal violet or safranin in Gram staining. The extract stained the bacteria red-orange and the plant nuclei‚ and the cytoplasm red and light pink‚ respectively. The study is limited to the ability of Basella rubra (alugbati) to be used as a biological stain 2011 Gel-O-Fury- Saavedra‚

Observation of Bacteria on Chicken and Handrail and the Effect of GermX® and Alcohol on Them. Sujit Bhimireddy‚ Daryl Onwuchuruba‚ Naveen Sood‚ and Manasa Tripuraneni Biology 106 Abstract Bacteria are found everywhere on this planet. This experiment is aimed at observing some of the bacteria that surround us in places that we use everyday. We will look at bacteria found on a piece of chicken and bacteria found on a handrail. The effectiveness of antibacterial substances such as GermX® and

PSBPP103 Differential Gram’s staining EXPERIMENT NO. 1 AIM: THEORY: Page No: C1 Date: To Gram stain the given bacterial suspension and to differentiate between gram positive and gram negative organism. Visualization of microorganisms in the living state is very difficult‚ not just because they are minute‚ but because they are transparent and almost colorless when suspended in an aqueous medium. To study their properties and divide microorganisms into specific groups for diagnostic purposes

CAP is usually acquired via inhalation or aspiration of pulmonary pathogenic organisms into a lung segment or lobe” (Medscape‚ 2015). The most common organisms involved in causing CAP are: Streptococcus pneumoniae‚ Haemophilus influenza‚ and Moraxella catarrhalis. 2. Discuss the pathophysiology of pneumonia.

classification of the invisible bacterial life. Bacterial classification is based on several major properties‚ CLASSIFICATION OF BACTERIA BASED ON GRAM STAINING This method of classification of bacteria was discovered by Hans Joachim Christian Gram 1883‚ a Danish Physician‚ while attempting to differentiate bacteria from human tissue by different staining methods. He noted differences in stain retention by bacteria due to

phagosome. This trouble-making characteristic of MTB made its identity obscured to be the diagnosed at the time when it was first discovered. This was because MTB was neither Gram negative or positive when it was Gram stained. Finally‚ the scientists employed different way of staining called acid-fast staining. Acid fast staining This technique allowed the scientists to diagnose the MTB. However‚ its treatment still remains somewhat problematic despite of its effective antibiotic treatment. This is

A gram positive bacteria outer membrane is absent and gram negative bacteria outer membrane is present. A gram positive bacteria’s peptidoglycan layer is 20-80 nm thick‚ whereas a gram negative bacteria’s cell peptidoglycan

bacteria and how they stain‚ whether it be gram positive or gram negative. Hypothesis: If I read the textbook and use the resource websites‚ then I will be able to better understand prokaryotes and describe the structural characteristics of viruses. By understanding prokaryotes‚ I can compare them to eukaryotes and learn more about the different types of prokaryote species.

testing in order to determine the identity of the unknown organism. The tests performed to identify the unknown organism included Gram Staining‚ Fluid thioglycollate/aero-tolerance test‚ Methyl Red-Vogues Proskauer‚ SIM test‚ Lysine Decarboxylase test‚ Lactose Fermentation test‚ Simmons Citrate test‚ and TSI test. The Gram staining technique showed that the organism was Gram negative and bacilli shaped. The fluid thioglycollate test showed that the organism was a facultative anaerobe‚ meaning ATP can
