Identification of Proteus vulgaris from an Unknown Sample Lakhram Bhisham March 31‚ 2016 01:447:390 General Microbiology TA: Jennifer Goff ABSTRACT This report delineates how unknown #405 was identified as Proteus vulgaris out of a possible seven species of Enterobacteriaceae by applying various tests that are able to distinguish between members of the family. Inevitably‚ the results for many tests are identical across multiple species‚ which is expected due to the organisms’ evolutionary relatedness

Proteus vulgaris #12 The importance of identification of a certain microorganisms can range between a life threatening diseases to a creation of certain antibiotic. Understanding the principals of living microbes and identifying my unknown bacteria through numerous biochemical and metabolism tests‚ with the outmost confidence‚ Proteus vulgaris had the precise qualifications. The point of this report is to further explore the identification of my unknown bacteria by revealing the results of the

Proteus Vulgaris Proteus vulgaris is a gram negative‚ facultatively anaerobic‚ bacillus rodchemoheterotroph bacterium belongs to the family Enterobacteriaceae. It possesses peritrichous flagella‚ making it actively motile. P.vulgaris occurs naturally the intestional tracts of humans and animals‚ soil‚ fecal matter‚ polluted water‚ and raw meat. It is grouped with the enterobacteriacea and is an opportunistic pathogen of humans. In humans P.vulgaris is known to cause urinary tract

The problem we are studying was to determine the cellular damage of various concentrations of propanol‚ ethanol‚ methanol‚ NaCL‚ and sodium dodecyl sulfate henceforth known as SDS on Beta vulgaris to ultimately distinguish the ability of each solution to permeate the membrane of the Beta vulgaris. • Beta vulgaris contains a beta cyanin which is a water-soluble red-pigment‚ which remains in a healthy vacuole surrounded by the tonoplast membrane. When we damage the tonoplast membrane and thus disrupt

Examination of Proteus Vulgaris by Carbohydrate Fermentation Tests Abstract: Some bacteria ferment certain carbohydrates‚ while producing acidic or gaseous products; this information can be utilized in order to identify bacteria (Morello and Granato‚ 2003). In order to test for carbohydrate fermentation‚ tubed broths‚ containing a Durham tube for trapping any gas formed when the broth is incubated‚ are utilized (Morello and Granato‚ 2003). After incubation‚ a color change indicates that

Proteus vulgaris Antibiotic Sensitivity Assay By: David Toelkes BIO 225 June 12‚ 2012 Lab Partners Alexis Blackmon Cheryl Cardiff Megan Dereani Logan Freeman Abstract Development of bacterial resistance to the antimicrobial drugs identified the need to determine a given bacterium’s susceptibility or resistance to a given drug which prompted W. M. M. Kirby and A. W. Bauer to develop a single disk method for susceptibility testing. This experiment used the Kirby-Bauer disk diffusion

Proteus mirabilis The genus Proteus‚ according to Bergey’s Manual of Determinative Bacteriology‚ is a group of straight rod Gram negative bacteria around 0.4-0.8 μm in diameter and 1-3 μm in length. In the microscopic test done‚ it was seen that the unknown culture contained rods that are on the shorter side‚ thus was identified as bacteria that appear to be coccobacilli. Because of the presence of peritrichous flagella‚ species included this genus are motile and most strains swarm in periodic cycles

Proteus Mirabilis Proteus mirabilis is part of the Enterobacteriaceae family. It is a small gram-negative Rod‚ and a facultative anaerobe‚ lastly‚ it is a Prokaryote. Furthermore‚ Proteus mirabilis is characterized by its swarming motility‚ its ability to ferment maltose‚ and its inability to ferment lactose. P. mirabilis has the ability to elongate itself and secrete a polysaccharide when in contact with solid surfaces‚ making it extremely motile on items such as medical equipment (catheters)

Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques

Ichthyosis Vulgaris Ichthyosis vulgaris is a member of a group of cutaneous disorders of keratinization and appear both clinically and histologically. Ichthyosis vulgaris disrupts this balance either because too many replacement skin cells are produced or because the skin cells do not separate well from the skin surface when it is their time to drop off. The result is that skin cells accumulate into thick flakes that adhere to the body. Ichthyosis vulgaris can be a nuisance‚ but rarely affects overall
