Additionally the development of recombinant DNA technology through the use of bacteria has led to the birth of modern genetic engineering and biotechnology. [ 9 ] Using microbes, protocols were developed to insert genes into bacterial plasmids , taking advantage of their fast reproduction, to make biofactories for the gene of interest.
This rapid evolution is important in medicine, as it has led to the development of multidrug resistant pathogenic bacteria, superbugs, that are resistant to antibiotics. [ 39 ] A possible transitional form of microorganism between a prokaryote and a eukaryote was discovered in 2012 by Japanese scientists.
Microbiology (from Ancient Greek μῑκρος (mīkros) 'small' βίος (bíos) 'life' and -λογία () 'study of') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).
Calymmatobacterium granulomatis; Campylobacter. Campylobacter coli; Campylobacter fetus; Campylobacter jejuni; Campylobacter pylori; Capnocytophaga canimorsus
Bergey's Manual Trust was established in 1936 to sustain the publication of Bergey's Manual of Determinative Bacteriology and supplementary reference works. The Trust also recognizes individuals who have made outstanding contributions to bacterial taxonomy by presentation of the Bergey Award and Bergey Medal, jointly supported by funds from the Trust and from Springer, the publishers of the ...
Consequently, the need to identify human pathogens was a major impetus for the development of techniques to identify bacteria. [ 173 ] The Gram stain , developed in 1884 by Hans Christian Gram , characterises bacteria based on the structural characteristics of their cell walls.
Scanning electron micrograph of Escherichia coli, a common human pathogen and research organism.. Bacteriology is the branch and specialty of biology that studies the morphology, ecology, genetics and biochemistry of bacteria as well as many other aspects related to them.
Logarithmically growing bacteria differ from stationary phase bacteria with respect to the number of genome copies present in the cell, and this has implications for the capability to carry out an important DNA repair process. During logarithmic growth, two or more copies of any particular region of the chromosome may be present in a bacterial ...
