The text covers the application of genetics in Microbiology research, microbial metabolism to provide a background on Comprehensiveness rating: 4 see less. The text covers the application of genetics in Microbiology research, microbial metabolism to provide a background on the function of microbes before delving into their role in diseases and human health.

This text is ideal for students planning to pursue a health related field. The book is missing several key words in the metabolism section, like lithotroph, chemotroph, and autotroph. There is no mention of reverse electron flow in the section on phototrophs. The glyoxylate pathway is missing and there is no mention of Gibbs free energy. From a public health perspective, this book is missing a section on indicator organisms and how they are used for water quality monitoring.

However, it does do an excellent job covering early epidemiologists John Snow and Florence Nightingale. The immunology section was much easier to read and understand than my current textbook.

The content is presented in an unbiased manner. The content provided is accurate, but their are errors of omission and errors of over simplification. For example, the nitrogen cycle is described as having only three steps: denitrification, nitrification, and nitrogen fixation. These aren't really steps, they are multistep processes. There are many other steps in the nitrogen cycle that are not included here.

The content will not become outdated quickly. It is easy to build on the content that is provided. This is both a strength and a weakness. With commercial text books, each chapter provides too much information and I can delete the excess info.

With this text book it would be necessary to spend time providing additional content to increase the depth.Author by : I DR.

The main key of microbial diversity on earth is due to evolution. The structural and functional diversity of any cell represents its evolutionary event which occurred through Darwinian Theory of natural selection. Natural selection and survival of fittest theory is involved on the microorganisms. This includes diversity within species, between species and of ecosystems. This was first used in the title of a scientific meeting in Washington, D.

The fungal diversity indicates the total number of species in a particular taxonomic group. The estimates of 1. Attempts to estimate total numbers of bacteria, archaea, and viruses even more problematical because of difficulties such as detection and recovery from the environment, incomplete knowledge of obligate microbial associations e.

On the other hand, there is one group Spiro plasma, which was discovered inmay be the largest genus on earth. Similarly, marine ecosystems likely support a luxuriant microbial diversity.

Further, microbial diversity can be seen on cell size, morphology, metabolism, motility, cell division, developmental biology, adaptation to extreme conditions, etc.

Introduction To Microbiology

The microbial diversity, therefore, appears in large measure to reflect obligate or facultative associations with higher organisms and to be determined by the spatiotemporal diversity of their hosts or associates.

Holben detected Brady-rhizobium japonicum selectively at densities as low as 4. Biological diversity or biodiversity is actually evolved as part of the evolution of organisms, and the smallest unit of microbial diversity is a species.

Bacteria, due to lack of sexuality, fossil records etc. Hence, a bacterial species is a genomic species based on DNA-DNA relatedness and the modern concept of bacterial species differs from those of other organisms. To date, more than 69, species in genera of fungi and about 4, species of about genera of bacteria have been described in the literature as given in Table 2.

The role of microorganisms both on land and water, including being the first colonizer, have ameliorating effects of naturally occurring and man-made disturbed environments. There are resources for new genes and organisms of value to biotechnology, there diversity patterns can be used for monitoring and predicting environmental change. Microorganisms play role in conservation and restoration biology of higher organisms. The microbial communities are excellent model for understanding biological interactions and evolutionary history.

Data bases are becoming more widely available as a source of molecular and macromolecular information on microorganisms. New- technologies are being developed that are based on diverse organisms from diagnostics to biosensors and to biocatalysts. It has also leashed new waves of creativity in the from of RNA sequence analysis to prove the metabolic activities and gene regulation of microbes in situ. The gainful advantages may occur by enriching microbial diversity.

Microbial genomes can be used for recombinant DNA technology and genetic engineering of organisms with environmental and energy related applications. Emergence of new human pathogen such as SARS is becoming quite important due to threat to public health can be solved by analyzing the genomes of such pathogen.

Culture collections can play a vital role in preserving the genetic diversity of microorganisms. This can be further strengthened by multidisciplinary involvement of experts.

Micro — organisms matter because they affect every aspects of our lives — they are in us, on us and around us. Microbiologists studt microbes and some of the most important discoveries that have underpinned modern society have resulted from the research of famous microbiologists, such as Jenner and his vaccine against smallpox, fleming and the discovery of penicillin, Marshall and the indentation of the link between Helicobacter pylori infections and stomach ulcers and zur husen who identified the link between papilloma viruses ans cervical cancers.

Sensitivity and Specificity When developing diagnostic tests or evaluating results, it is important to understand how reliable those tests and therefore the results obtained are. By using samples of known disease status, values such as sensitivity and specificity can be calculated that allow its evaluation.

It is a broth medium used for the growth of the organism and a base for determining carbohydrate fermentation patterns of non-fastidious organisms. In addition, it is also used for the detection of indole production by the organism. These natural polymers include polysaccharides, such as cellulose, chitin, starch, alginate, galactan, hyaluronic acid, dextran, and gellan, obtained from plants, animals, and microbial sources and polyesters, such as poly b-hydroxybutyrate and poly b-hydroxybutyrate-co-b—hydroxyvalerateproduced by numerous bacteria.

General Aseptic Techniques in Microbiology Laboratory Aseptic technique is a set of routine measures that are taken to prevent cultures, sterile media stocks, and other solutions from being contaminated by unwanted microorganisms i. Direct Microscopic Counts Studies involving the analysis of materials including food, water, milk, and, in some cases, air require quantitative enumeration of microorganisms in the substances.

Many methods have been devised to accomplish this, including direct microscopic counts, use of an electronic cell counter such as the Coulter Counter, chemical methods for estimating cell mass … Read more Direct Microscopic Counts.
