Advances in fish microbiology and pathology

Fish pathology

Combined with automation, modern microbiology offers high throughput options for large numbers of specimens at reasonable cost. Currently, FISH technology is most commonly used to identify bacteria and fungi in blood cultures by targeting specific microbial DNA sequences and is particularly valuable for candidaemia. Daily life is interwoven inextricably with microorganisms. Historical background Microbiology essentially began with the development of the microscope. First off the block were radioactively labelled hybridisation probes developed by Joseph Gall and Mary Lou Pardue in the s. The establishment of sequence databases in GenBank and the Ribosomal Database Project allows comparison of the test result with known bacterial and fungal species. Progress in the 20th century All of these developments occurred in Europe. Building on the discovery of the structure of DNA and the genetic code, four main scientific advances have been made which underpin these techniques hybridisation probes, polymerase chain reaction, the observation that the microbial species signature can be read in the ribosomal genes and also in the proteins. Although others may have seen microbes before him, it was Antonie van Leeuwenhoek , a Dutch draper whose hobby was lens grinding and making microscopes, who was the first to provide proper documentation of his observations. They also elaborated an extensive arsenal of techniques and laboratory procedures for revealing the ubiquity, diversity , and abilities of microbes. The field is concerned with the structure, function, and classification of such organisms and with ways of both exploiting and controlling their activities. The aim of this article is not to review all the new technologies available but to provide the non-specialist with an insight into the inner workings of the modern clinical microbiology laboratory and the benefits provided for both patient and clinician. More user-friendly fluorophores replaced the radioactive labels leading to the development of fluorescence in situ hybridisation FISH. Leeuwenhoek conveyed his findings in a series of letters to the British Royal Society during the mids. In resource-poor settings, molecular techniques and automated systems may seem unaffordable but new public-private partnerships, initiatives by the World Health Organization and new, innovative laboratory methods offer the promise of benefit for all.

It was only later, during the 18th-century revival of a long-standing controversy about whether life could develop out of nonliving material, that the significance of microorganisms in the scheme of nature and in the health and welfare of humans became evident.

The benefits for the clinician and patient include confirmation of clinical diagnoses and information about antimicrobial susceptibility within hours compared to days for conventional methods.

Although his observations stimulated much interest, no one made a serious attempt either to repeat or to extend them.

However, while the cost of processing each specimen may be attractive, the price of the required equipment may not. In this article, the development of modern microbiology is traced from the discovery of the structure of DNA to applications for the clinical laboratory.

The establishment of sequence databases in GenBank and the Ribosomal Database Project allows comparison of the test result with known bacterial and fungal species.

His descriptions and drawings included protozoans from the guts of animals and bacteria from teeth scrapings.

They also elaborated an extensive arsenal of techniques and laboratory procedures for revealing the ubiquity, diversityand abilities of microbes. Microorganisms have also been effectively utilized in industry; their activities have been channeled to the extent that valuable products are now both vital and commonplace.

Although Francesco Redi , an Italian physician, disproved in that higher forms of life could originate spontaneously, proponents of the concept claimed that microbes were different and did indeed arise in this way. Keywords: Microbiology, molecular methods, resource-poor Introduction For some time, a quiet revolution has been taking place inside the hospital microbiology laboratory. However, while the cost of processing each specimen may be attractive, the price of the required equipment may not. Aristotle discarded this notion, but he still held that animals could arise spontaneously from dissimilar organisms or from soil. Historical background Microbiology essentially began with the development of the microscope. Students of Pasteur, Koch, and others discovered in rapid succession a host of bacteria capable of causing specific diseases pathogens. Building on the discovery of the structure of DNA and the genetic code, four main scientific advances have been made which underpin these techniques hybridisation probes, polymerase chain reaction, the observation that the microbial species signature can be read in the ribosomal genes and also in the proteins. Microorganisms have also been effectively utilized in industry; their activities have been channeled to the extent that valuable products are now both vital and commonplace. His descriptions and drawings included protozoans from the guts of animals and bacteria from teeth scrapings. In addition to populating both the inner and outer surfaces of the human body , microbes abound in the soil , in the seas, and in the air.
