Introduction The Gram stain is one of the most useful staining procedures in microbiology . It is one of three differential staining techniques‚ is used to identify divide bacteria into two groups: Gram-positive bacteria and gram-negative (Madigan‚ Martinko‚ Dunlap‚ Clark (2009). These staining reactions take advantage of the fact that cells or structures within cells display dissimilar staining reactions that can be distinguished by the use of different dyes (Brown 2009).

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 I will discuss three spontaneous generation experiments and explain why it is obsolete in today’s science. History of Microbiology Since Microbiology is the study of microorganisms‚ it is understandable

I’m writing you to express my interest in becoming a member of the ASM Task Committee on Microbiology in Nursing. Although I’m not from the United States of America‚ I think this committee might profit from an European perspective and my experience‚ so I will use this opportunity to quickly introduce myself. I’m a medical doctor and clinical microbiologist with a PhD in biomedical sciences‚ and after my doctoral degree I quickly became an assistant professor at the Department for Biomedical Sciences

HOW TO WRITE AN UNKNOWN LAB REPORT IN MICROBIOLOGY GENERAL Unknown reports in microbiology are written in scientific format. Scientific writing is written differently from other types of writing. The results of the exercise or experiment are what are being showcased‚ not the writing. The purpose of scientific writing is not to entertain‚ but to inform. The writing should be simple and easy to understand. There is a specific style that must be followed when writing scientific reports.

M. GR~SCHEL Walther Hesse was a well-known community health physician in the Kingdom of Saxony‚ a student of Max von Pettenkofer‚ the father of hygiene‚ and of Robert Koch‚ the father of medical microbiology. His American wife‚ Fanny Angelina‚ introduced agar-agar to the new science of microbiology. The Hesse Family Walther Hesse‚ a descendent of a Saxon family from Bischofswerda‚ was born on 27 December 1846 as the third of 12 children of Friedrich Wilhelm Hesse‚ the Bezirksarzt‚ or county

Safety in a microbiology laboratory is important in the prevention of infection that might be caused by the microorganisms being studied. This laboratory does not require the use of virulent human pathogens. However‚ many types of microorganisms are potentially pathogenic. This means that‚ although they would not cause disease in a normal healthy host‚ they might possibly do so if a large enough quantity of the microbes came into contact with a compromised host‚ such as by wounds and cuts.

The decomposition that microbes take part in help release mineral nutrients‚ such as potassium and nitrogen‚ from dead organic matter and allowing primary producers the nutritional access. They also produce CO2 and CH4 to release into the soil and atmosphere. 3. Describe the growth you observed in each of your
