Human interactions with microbes include both practical and symbolic uses of microbes, and negative interactions in the form of human, domestic animal, and crop diseases. Practical use of microbes began in ancient times with fermentation in food processing ; bread , beer and wine have been produced by yeasts from the dawn of civilisation, such ...
Microbes and Man is a popularising book by the English microbiologist John Postgate FRS [1] on the role of microorganisms in human society, first published in 1969, and still in print in 2017. Critics called it a "classic" [ 2 ] and "a pleasure to read".
Microbes are important in human culture and health in many ways, serving to ferment foods and treat sewage, and to produce fuel, enzymes, and other bioactive compounds. Microbes are essential tools in biology as model organisms and have been put to use in biological warfare and bioterrorism. Microbes are a vital component of fertile soil.
Campbell is best known for his work on parasitic diseases. Japanese microbiologist Satoshi Ōmura isolated and cultured many varieties of natural soil-based bacteria from the group Streptomyces. Campbell led a team at Merck in studying Ōmura's cultures and examining their effectiveness in treating parasites in domestic and farm animals.
Graphic depicting the human skin microbiota, with relative prevalences of various classes of bacteria. The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, [1] [2] including the gastrointestinal tract, skin, mammary glands, seminal fluid, uterus, ovarian follicles, lung ...
Depiction of prevalences of various classes of bacteria at selected sites on human skin. Prior to the HMP launch, it was often reported in popular media and scientific literature that there are about 10 times as many microbial cells and 100 times as many microbial genes in the human body as there are human cells; this figure was based on estimates that the human microbiome includes around 100 ...
Scientists have also exploited their knowledge of microbes to produce biotechnologically important enzymes such as Taq polymerase, [27] reporter genes for use in other genetic systems and novel molecular biology techniques such as the yeast two-hybrid system. [28] Bacteria can be used for the industrial production of amino acids.
Further paradigm shifts occurred at the beginning of this century and still continue, as new sequencing technologies and accumulated sequence data have highlighted both the ubiquity of microbial communities in association within higher organisms and the critical roles of microbes in human, animal, and plant health.
