Microbiology

Microbes - bacteria, archaea, fungi, algae, protozoa and viruses - have been around for at least 3,500 million years and were the only life forms on Earth for most of that time. Microbiology is the study of these small organisms. A microorganism or microbe is an organism that is microscopic. The development of the microscope, along with the observations of various scientists, led to the discovery of microorganisms. It is thanks to Van Leeuwenhoek who is largely credited with the discovery of microbes, and Hooke who is credited as the first scientist to describe live processes under a microscope, Spallanzani and Pasteur who performed several experiments that demonstrated that microbial life does not arise spontaneously, Cohn who laid the groundwork…

Microbiology laboratory is a branch of clinical laboratory. The main purpose of the microbiology laboratory is work to discover the reasons and causes of the diseases and treatment. Microbiology laboratory is one of important laboratory in clinical laboratory, because interested in studying infectious diseases. There are four type of microorganisms that causes infectious disease are bacteria, parasites, fungi and viruses. Microbiology laboratory has many sections and each section do many types…

Extraordinary Science of Microbiology There are a wide variety of microorganisms in this world. The major groups of microorganisms include bacteria and fungi. These microorganisms are found all over the earth. The study of microorganisms started in the mid-1600’s. Most people believed that microorganisms only spread deadly diseases, but scientists proved that microorganisms can also be beneficial to human life. The wide variety of microorganisms that are found everywhere are most well…

Disease and infection are an inevitable part of being human, but also an intriguing part. I first became aware of the possibilities of studying microbiology when I attended a lecture on “Microbiology and Bioterrorism” at the Medlink Conference at Nottingham University in 2014. I found this lecture really interesting, and left the Conference wanting to know more about microbiology. Studying Biology at A2 has led me to realise the incredible impact that microorganisms have on every aspect of our…

Dalise Atwell BIO 212 Dr. Boles Excelsior College Penicillin and its Impact on Microbiology Penicillin has saved many lives past and current. “Before the discovery and use of penicillin, infectious diseases had been the leading cause of death throughout history. Furthermore, the therapeutic tools available for treating infections were few and of limited use.”(Kardos 2011) Penicillin has been the drug of choice when treating many diseases. Even though there are people allergic to…

Natalia Sidorova BIO 2483 - Marisa Yoder Microbiology Lab Report March 20th, 2018 Genus Identification of Unknown Bacterial Cultures Intro For a microbiologist, the most important part of their work is finding the identification of the unknown bacteria that they are working with. Everything they do, from finding the cure for a disease or learning how to cultivate it, depends on the identification of the bacteria. This study’s performance had the purpose of finding the cultural and…

Van Tran Microbiology Tuesday 5:00 May 5, 2015 Unknown Sample # 7 1. Introduction: Using biochemical tests are a good way to identify unknown bacteria from a sample. It is basically a similar to a trial and error method, but rather than using trial and error a person would be using positive and negative results. Using biochemical tests will help a person identify certain characteristics of the unknown bacteria through a series of chemical tests. Of course more than one biochemical tests…

Introduction: Microbiology is the study of all living microorganisms like bacteria, fungi, protozoans…etc, and non-living microorganisms like viruses, viroids and prions. The significance of identifying an unknown microorganism is first to understand what type of organism it is and what structures it has to help figure out their potential benefit, danger or even neutrality to humans. Physicians benefit from this by identifying what their patients are suffering from and how to treat them. Also…

Unknown #11: Introduction: My patient’s name is Cara, she is currently a freshman living in a dormitory with three friends. Just two weeks in, she catches the flu. Her roommates made her soup for the next couple of days from their shared pantry of foods. Cara however progressively becomes worse and now exhibits severe symptoms of nausea and diarrhea. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of…

Introduction Microbiology is a very interesting subject within all biology-related sciences. It deals with the study of the micro world around us and its inhabitants, whether they are inside us like our normal microbiota or what most people call “your friendly gut bacteria”; and all the other disease-causing microbes found inside and outside the human body. Till this very day, countless experiments have been conducted with the sole purpose of broadening our knowledge about the microorganisms…
