Antibiotic sensitivity
Newer non- automated susceptibility tests (Chu, Afzah-Shah, Huang, Palepou, & Lyon, 2001), and the molecular tests (Kirby, Sader, Walsh, & Jones, 2004). Each of the listed tests above is applicable in either of the two cases of bacterial resistance. Bacteria exhibit two kinds of resistance to antibiotics; these are the intrinsic resistance and the acquired resistance. Intrinsic resistance is a condition whereby the bacteria are naturally resistant to a given antibiotic even before its use.

Citrobacter freundii
Citrobacter freundii is characterized by various opportunistic infections including a variety of nosocomial infections of the respiratory tract, blood, urinary tract and other sterile sites in patients with suppressed immune system (MicrobeWiki, 2011). Research has revealed that C. freundii is responsible for over 29% of all the opportunistic infections (Leboffe & Pierce, 2011). It is therefore important not only to be able to isolate the bacterium but also to sequence its many different

The Interaction of UTI with Different E.coli ESBL+ Strains and Enzymes
The main reason for the increase in Urinary tract infections are the increasing antimicrobial resistance of human pathogens. The antimicrobial agents are becoming less effective against the human pathogens because of the increasing resistance against them. The studies have shown that Enterobacteriaceae are gaining resistance against the antimicrobial agents and have become the main reason for UTI.Escherichia coli are Gram negative bacteria that are found in the warm blooded organisms at the

Descriptive Lab Report - Intro.Microbiology Lab (Serial Dilution)
Serial dilution is the first step for studying individual microbes out of the soil, which is densely populated with microbes. In addition, by going back to dilution, one can also appreciate how various and numerous microbes are living inside the soil. This experiment majorly aims to determine the number as well as the types of microbes present in a particular soil sample used. It is not practical to find all microbes viable and cultivable. The reason is, majority of the microbes have been

Enumeration and Growth
One of the commonly used methods is the standard plate count which is based on the assumption that each colony arises from a single bacterium. The number of bacteria is thus determined by counting the number of colonies arising from a culture. The disadvantage of this method is that if the bacteria are many, the colonies will grow on top of each other making it hard to count them (Zourob et al 45). This disadvantage is overcome by diluting the original culture and spreading them on plates to

Soil Enzyme Activity
Enzymes are therefore dependent on substrate concentration, soil microorganisms’ metabolic ability, soil environmental conditions such as temperature and pH and the number of microorganisms present in the soil (Lichtfouse, 228).Alkaline Phosphatase is an example of extracellular enzyme produced by many soil microorganisms and exported out into the soil solution. The main function is to eliminate the phosphate molecule from the organic compounds such as nucleic acids and phospholipids. This

Transformation of E.coli with plasmid DNA & GFP purification
Major purpose of this experiment is to study the transformation of E.coli, to express GFP protein, and the isolation of GFP, per se. The bacterial transformation will be achieved by using pGLO whereby the DNA is incubated with the bacteria in a solution of CaCl2 to allow the DNA to bind in a non-specific way to the bacteria surface. For the extraction of GFP, column chromatography will be used, with aid of salt concentration that dictates protein-ligand interaction.Two closed microfuge were

Identification of unknown
Collected bacterial colony from and streaked on the EMB plate and waited for some days to observe the result. The unknown bacteria was Gram negative. With G –ve result I had to carry more tests: Oxidase test, Lactose fermentation test, Indole test, Bile Esculin test, Motility test, Methyl Red -Voges Proskauer test, and Lysine decarboxylase test.Oxidase test: Obtained a liquid culture stock of my gram negative unknown bacteria and a dry oxidase test slide. Smeared 20 ul of the liquid

FOOD MICROBIOLOGY
However, according to (Public Health England, 2014) there was an outbreak of Salmonella Enteritidis that caused three deaths and an outbreak of 247 cases from 158 on 15th of August 2014. There were 99 cases in Hampshire, 39 in Cheshire, 30 in London and 54 in the West Midlands. Salmonella Enteritidis is a bacterium that causes gastrointestinal illness and is often associated with poultry and eggs.Salmonella belongs to the Enterobacteriaceae and are facultative anaerobic Gram-negative bacilli.

Selective Media
Such media is referred to as selective media because it either enhances or inhibits the growth. Using selecting media makes it easy to discriminate most unwanted pathogens that arise from environmental contamination and likely to give false positive diagnosis. This report assessed the growth, morphology characteristics, differential colony features of the four selected microorganisms (E. coli, Salmonella tyhimum, Shigella flecked, and Staphylococcus spp) on five selected selective media

Categorising Microbes, aims, methods, and results of labs, discussion of experiment
Gram staining is one of the commonly used methods to differentiate microbes after examination under light microscopy and beyond the genus level. Gram staining procedure is used to categorize microbes according to biochemical composition of the bacteria and the distribution of biochemical within the microbial cells. Gram-negative bacteria are those that contain lipopolysaccharides which play important role of regulating the permeability of the cell among other functions. Gram-positive

Serratia marcescens
The first procedure of the identification process for the unknown microorganism involved carrying out an acid fast stain test. A smear of the unknown organism to be stained was heat fixed by passing it through the flames of a Bunsen burner. Next, an absorbent paper was placed over the smear and heated for 5 minutes. The slide was then removed and rinsed. After decoloration with acid-alcohol, the slide was rinsed again and a counter-stain of methylene blue was applied. I was rinsed and finally
