Microbiology Reports Samples For Students

The fight against pathogenenic microorganisms to achieve a better life has been a continuous process. Rapid changes are seen as researches are embarking upon various forms of studies but there are certain discoveries that always seem greater. The New York Times published an article, which focus on the advancement in microbe genome sequencing technology. The article title "The new generation of microbe hunters" explored the challenges, the need, and future benefits of the new technology.
This publication provides a summary of some medic's perception and discussion of the current rapid infective process of microbes on human health in a neighboring city and ...

“The expression of ampicillin resistance and luciferase enzyme genes by E. coli transformation using the pUC18 and lux plasmids”
Abstract
The transformation process allows the uptake of DNA from the environment, with the incorporation and expression of genes. During this process, changes in the DNA of the receptor cell occur, producing some selective advantages in some cases, such as resistance to antibiotics. pUC18 and lux plasmids were used to determine the transformation process in Escherichia coli. Cells were made competent by the addition of calcium chloride and heat shock in order to induce the incorporation of the ...

Identification of mystery microbe based on its morphology and biochemical properties

The experiment was conducted to detect the species of a given mystery microbe. The microbe was subjected to a battery of tests in order to identify its physical and biochemical characteristics. Based on the tests, different possible microbe species were eliminated to finally arrive at the right conclusion. The possible microbes included Escherichia coli, Providencia alcalifaciens, Enterobacter aerogenes, Staphylococcus epidermidis, Klebsiella pneumonia, Micrococcus luteus, Serratia marcescens, Mycobacterium smegmatis, Sarcina aurantiaca, Pseudomonas aeruginosa and Bacillus licheniformis.
The first test conducted was to detect the Gram staining properties of the given microbe. This helped in identifying whether the given microbe had a thin ...

Abstract

The report presents the results of a microbiological experiment to confirm the hypothesis that as leftover food sits out over time, the number of bacteria in the food will increase. The study was undertaken to indicate the risk of bacterial contamination and the importance of proper storage technique. The study was performed using a liquid food (corn tortilla soup) which was exposed to the external environment at room temperature. The control group in our experiment was the same food stored in a zip lock bag and refrigerated.
The soup was tested over a period of time, which served as the independent variable, ...

Antibiotic resistance occurs when there is a gain or change in the DNA of the bacterial organism. Most mechanisms of antibiotic resistance are associated with plasmid-mediated transfer of genetic information; using transposons facilitates the transfer of information, and in fact many common modes of resistance are associated with transposons such as beta – lactamases, tetracycline resistance and aminoglycoside resistance (Microbiology, 2007 pg. 64-65). Resistance is accomplished by one of three mechanisms (Microbiology, 2007 pg.65):
- Decreased uptake
- Alteration of target site: A change in the penicillin binding site of certain bacterial cell walls leads to less binding. ...

INTRODUCTION:

Pathologists or microbiologists play a very vital role in the management and diagnosis of any disease. They get immense help by performing certain series of tests which aids them reaching to a conclusion. One such test is called as gram staining which is used widely as the most primitive test for the identification of various bacteria
According to Beveridge, the gram stain essentially delineates bacteria into two broad categories. It does that by giving color to these bacteria and bacteria that attains purple or violet color are ...

Purpose
Materials and Methods
Gram Staining: Three circles were marked at the bottom of a clean glass slide and they were labeled as gram(+), gram(-) and unknown respectively. The three labeled circles were then inoculated with microorganism 6 using an inoculating loop. The bacterial smears were then air dried and heat fixed over a gentle flame. The slide was then flooded with primary stain, crystal violet for a minute by placing it on a staining rack. Excess crystal violet was washed off with a gentle stream of water. Thereafter, gram iodine was added and ...

Introduction
In recent times, synthetic antibiotics have caused resistance in microorganisms and also, have shown unwanted side-effects. This has demanded for alternate therapies to combat infections. Scientists have developed interest in plant extracts, especially the ones that are traditionally used as spices, for new antimicrobial agents. Spices are traditionally used to give a distinctive flavor to the food but, they also contain potential antimicrobials which are also documented in literature. Even Louis Pasteur demonstrated the antibacterial effect of garlic and onion extracts. Salsa contains three main ingredients which have potential antimicrobial compounds. First, Lemon (Citrus Limon) is reported to ...

Abstract
Bacteriophages are intracellular parasitic viruses that infect bacteria to carry out their multiplication. During the lytic infection cycles, phages lyse the host cells forming a clear zone called plaque on the agar media. The experiment is aimed to measure the number of plaques created when the virus T4 infects the host bacteria and their genetic material integrates into the genetic material of the host cell. This happens because the E.coli becomes resistant to T4 bacteriophage. The T4 phage was diluted in a test tube and then E.coli bacteria was added in the tubes. The mixture was poured with soft ...

The process of identifying an organism involves the determination of where an isolate or an organism needs to be placed within a group of organisms that are already known. The process is usually done to conform to a given scheme of classification. Most of the microorganisms that may be found in the environment require to be identified aiming at identifying the different species that may be found in a given environment. The identification enables physicists and health workers to associated different sources with different organisms especially those that cause diseases. Organism classification may also help in the diagnosis of different disease by ...

Pressure has over the time has been an important aspect in the thermal sterlialization of food . This is an alternative thermal process of food preservation which is highly effective(PATS) .The (PAT) is important in that it releases the diplicinic acid also known as the (DPA) from the individual endospores. It also rehydrates the core of the endospores and allows the process of the spore inactivation. A good combination can include 200 to 800 mpa which will also be at one hundred and twenty degrees, this combination can effectively eliminate any resistant spores of the organism Clostridium Botulinum. At a ...

INTRODUCTION
Purpose
The purpose of the lab is to separate characterize and identify microbes from unknown mixed culture using the morphological and biochemical methods.

Theory

The process of identifying bacteria is a systematic and careful process which uses various techniques to narrow down the bacteria types which are present in an unknown culture of bacteria. This process produces advantages for many factors of research of microorganisms and assists in the proper treatment of patients (Aneja 10). Several tests were performed to give the fermentation abilities, availability of specific enzymes and specific biochemical reactions.

Introduction

Bacillus Subtilis are the organisms that are aerobic, Gram Positive, spore-forming belonging to the Bacillus genus. The organisms are together with other species that are closely related play a crucial role in disease, food poisoning as well as food spoilage. Lack of methods that are standardized for the identification of the organisms whether coming from the food or environment has made the tests to be difficult. Use of morphological as well as physiological tests have offered the best ways to identify organisms in the laboratory although there are inconsistent and lack of reliance in these methods.
