Importance of Microbiology

While microbes are often viewed negatively due to their association with many human illnesses, microbes are also responsible for many beneficial processes such as industrial fermentation (e.g. the production of alcohol and dairy products), antibiotic production and as vehicles for cloning in higher organisms such as plants. Scientists have also exploited their knowledge of microbes […]

Smear Preparation and Microbial Staining

Smear preparation and microbial staining were conducted following methods as indicated on Ex. 10-13 of the Laboratory Manual. Smear preparation was prepared using two types of media: solid (E. coli) and liquid media (B. megaterium). Two loopfuls of liquid inoculum was transferred to the marked circumference on the slide. For the solid media, only a […]

Sir Alexander Fleming is The Penicillin Man

“When I woke up just after dawn on September 28, 1928, I certainly didn’t plan to revolutionise all medicine by discovering the world’s first antibiotic, or bacteria killer,” Fleming would later say, “But I suppose that was exactly what I did”. And we should thank him every time when we get sick and take the […]

Junior research project

While obtaining the information for my junior research project I came across something that I felt was a major problem. This problem that I realized is what I am planning on doing for my junior research project. I realized that a certain thing has slowly been wreaking havoc on our communities. This was such an […]

Unknown Lab

The possible identity of the unknown organisms in the mixed culture was limited to bacteria that we had worked with previously in lab. Initially a Gram stain was conducted in order to distinguish the unknown bacterium as a Gram-positive and/or a Gram-negative organism (Lancaster and Bennett, 2012; Kellenberger, 2001). Based upon the results, both Gram-negative […]

Prevalence and Antimicrobial Profiles of Shigella

Abstract Background: Shigellosis is a major public health problem and increasing antimicrobial resistance has complicated its treatment. This study was aimed at determining the prevalence of Shigella species and their antimicrobial resistance patterns among patients visiting Kenyatta University health unit, Nairobi Kenya, during May-August 2011. Findings: Of the 102 stool samples cultured, 16 (15. 7%) […]

Unknown Lab Report

All bacteria, whether “good” or “bad” play an important role in all aspects of life. Knowing the individual identity of these microorganisms is particularly important in the development of technology in the medical and food industries. For example, knowing the culprit of particular illnesses is the key for determining proper treatment of an infected patient […]

Isolation of Microorganisms from Environmental Samples

It is crucial in the field of microbiology to study the morphology, biological activity, and the behavior of microbes thus the isolation of such microbes from the environment is necessary because it allows scientists to study them in close proximity. Microbial life forms are found everywhere. They are major players in biogeochemical cycling of elements […]

Campylobacter: An Enteric Microorganism

History of Campylobacter The initial discovery of Campylobacter was made by a German-Austrian pediatrician named Theodor Escherich in 1886. His observation and description led him to conclude that these spiral shaped, non-culturable bacteria were capylobacters. In 1913, Vibrio-like bacteria were isolated from the fetuses of aborted ovines by Stockman and McFadyean. It was followed by […]

Microbiology

1. A functional cell could be built with a single chromosome,cytoplasm,a cell membrane, and ribosomes.Why are these four components absolutely necessary to the functional cell? If these structures are all a cell needs, why do most cells have many more structures? A chromosome is necessary so that there is a “map” of the cells function […]

Introduction to the Microbial World

Microbiology is the branch of Biology that deals with the study of microorganisms and how they influence or work with other living organisms. (Satellite Events Enterprises Inc., 1999) In this paper I will discuss the history of Microbiology and specifically the early theory of spontaneous generation. I will discuss three spontaneous generation experiments and explain […]
