Comparison of Two Chromogenic Media for Selective Isolation of Vancomycin-Resistant Enterococci for Stool Specimens SUMMARY:               Bacteria are widely known agents of diseases not just in humans, but almost in all organisms. The study of bacteria, known as microbiology, has already found an antidote to the common bacteria known to infect and infest different organisms….

ns Of Nutrient BrothGrowth Dynamics of E. coli in Varying Concentrations of Nutrient Broths, pH, andin the Presence of an AntibioticDvora Szego,Elysia PrestonDarcy Kmiotek,Brian LibbyDepartment of BiologyRensselaer Polytechnic InstituteTroy, NY 12180AbstractThe purpose in this experiment of growth dynamics of E. coli in varying mediawas to determine which media produces the maximum number of cells per…

Primarily, the Archaea were once believed to be just another rare group of bacteria, because like bacteria, they are single-celled microscopic prokaryotic organisms with no membrane bound nucleus (http://www. fossilmuseum. net/Evolution/archaeaevolution. htm). Despite the similarities in the cell structure of Eubacteria and Achaea, molecular research by Dr Carl Woese and his co-workers indicated that they…

Several methods, like disc diffusion, E-test, agar dilution, broth microdilution and broth microdilution are suited for in vitro antimicrobic susceptibleness testing ( AST ). Whichever method is used, the trials have to be performed in conformity with an internationally recognized process, such as those published by the Clinical and Laboratory Standards Institute ( CLSI ),…

The 4 different types of microbes than can cause disease are; Bacteria Bacteria, also known as Bacterium in the singular term, are a prokaryote. Prokaryotes are simple , single celled organisms. Bacteria get their nutrients from the environments in which they live, in some cases, that is the human body.  They are larger than viruses,…

Preliminary work revealed that both toothpastes have an antibacterial effect on Micrococcus luteus. According to the preliminary study, the zone of inhibition of blend-a-med was slightly bigger than Colgate’s. Therefore the antibacterial effect of blend-a-med is greater than Colgate’s. Both toothpastes contain an antimicrobial ingredient Triclosan which kills many harmful bacteria. Triclosan ultimately results in…

The role of bacteria in the soil Bacteria in the soil play key role in recycling matter in to useful nutrients which can be used by growing plants. This process of recycling matter in the soil by living organisms is called biogeochemical cycle. Bacteria are improving plants growth in other ways too, for example bacteria,…

Introduction This work of identification of bacterium was performed through different biochemical tests. Unknown cultures were streaked on EMB, SS and MacConkey agar plates to distinguish the lactose and lactose non-0feremnetros and to identify the grams nature of the culture. The culture was also streaked on TSI agar slants to confirm the cultures ability to…

The text aims to clarify the purpose… The aim of this lab is to familiarize students with a variety of lab equipment, such as microscopes, square glass, and cover slips. The main focus is on observing pond water and identifying various microbes within it, including bacteria, algae, fungi, and protozoa. Furthermore, the experiment will teach…

Abstract This paper looks at the issue of antibiotic-resistant bacteria by focusing on the present data, ways on how this condition arises and finally proposing ways of how to overcome this problem. Introduction The discovery of antibiotics brought a new victory in fighting bacteria which were major causes of diseases. With time some of these…
