microbiology class at Brunswick Community College. This journey started out with a media plate cultured with an unknown species of bacteria. I was then instructed by my professor to use all of my previous knowledge to identify the unknown bacterial pathogen. This lab led me to master my skills of using the Gram stain‚ testing for catalase‚ testing for coagulase and using the oxacillin screen. Now I am going to take you with me on the journey to the unknown. As I recall from earlier that semester

Practical 9: Examination of Bacterial Plates Objective: 1. To examine bacteria pigmentation‚ colony‚ margin characteristics‚ elevation properties‚ broth characteristics and agar stroke properties. 2. To examine bacteria growth characteristics on different culture media. Introduction: Bacterial species can sometimes be identified on the basis of how they appear on or in the different media. The pigmentation‚ size and shape of bacterial colonies as they grow on and in agar plates can

What are bacteria? Bacteria are tiny little organisms that are everywhere around us. We can’t see them without a microscope because they are so small‚ but they are in the air‚ on our skin‚ in our bodies‚ in the ground‚ and all throughout nature. Bacteria are single-celled microorganisms. Their cell structure is unique in that they don’t have a nucleus and most bacteria have cell walls similar to plant cells. They come in all sorts of shapes including rods‚ spirals‚ and spheres. Some bacteria

Liquid or fluid appearance is visible. Bacteria and background don’t have a much of difference in color. Although‚ bacteria are defined and visible noted. Most of the time they are single round cells. In direct stain with crystal violet‚ again background is colorless and glossy. Bacteria is blue and some

Bacterial vaginosis‚ or simply BV‚ is a prevailing vaginal infection in women. BV is an illness that outcomes in vaginal discharge and are a consequence of overgrowth of usual bacteria in the vagina. There are numerous kinds of bacteria that live naturally in the vaginal region. The vaginal discharge results when numbers of various species of bacteria grow large such that their numbers exceed the natural balance (Bacterial Vaginosis Researchomatic). The reasons for the specific vaginal bacterial

Microbial metabolism is the means by which a microbe obtains the energy and nutrients (e.g. carbon) it needs to live and reproduce. Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics. The specific metabolic properties of a microbe are the major factors in determining that microbe’s ecological niche‚ and often allow for that microbe to be useful in industrial processes or responsible for biogeochemical

outcomes of spontaneous bacterial peritonitis in Egypt‚ single center experience prospective study Spontaneous bacterial peritonitis (SBP) is the infection of the ascetic fluid that occur in the absence of a visceral perforation and in the absence of an intraabdominal inflammatory focus such as abscess‚ acute pancreatitis or cholecystitis (Guarner C and Soriano G‚ 2007). Since its initial description in 1964‚ research has transformed spontaneous bacterial peritonitis (SBP) from a

Bacterial Energetics and Membranes Abstract The Mg2+/Ca2+ ATP synthase present in all bacterial membranes‚ particularly E. coli‚ couples ATP synthesis to the proton (H+) gradient produced by the ETC‚ a process known as oxidative phosphorylation. The gradient acts to power the ATPase‚ so that it may phosphorylate ADP to produce ATP. The reverse reaction of this process‚ or hydrolysis of ATP into ADP and Pi‚ may be used to observe ATPase activity when the resulting Pi is quantitatively measured

Bacterial Fermentation Secondary article Article Contents Volker Mu¨ller‚ Ludwig-Maximilians-Universita¨t Mu¨nchen‚ Munich‚ Germany . Introduction Under anaerobic conditions‚ in the dark and in the absence of electron acceptors‚ organic compounds are catabolized by strictly anaerobic or facultatively anaerobic bacteria by internally balanced oxidation–reduction reactions‚ a process called fermentation. In fermentation‚ the organic compound serves as both electron donor and acceptor‚ and adenosine
