List of microbiologists

Major contributions to the science of microbiology as a discipline in its modern sense have spanned the time from the midth century to the present day. The following is a list of prominent microbiologists who have made significant contributions to the study of microorganisms. Many of those listed have received a Nobel prize for their contributions to the field of microbiology. The others are typically considered historical figures whose work in microbiology had a notable impact in the field. Those microbiologists who currently work in the field have been excluded unless they have received recognition beyond that of being on the faculty in a college or university. From Wikipedia, the free encyclopedia.

Pre-microbiology, the possibility that microorganisms existed was discussed for many centuries before their actual discovery in the 17 th century. In his first century book, On Agriculture, Roman scholar Marcus Terentius Varro was the first known to suggest the possibility of disease spreading by yet unseen organisms. In , Girolamo Fracastoro proposed that epidemic diseases were caused by transferable seed-like entities that could transmit infection by direct or indirect contact, or even without contact over long distances. All these early claims about the existence of microorganisms were speculative and were not based on any data or science. Microorganisms were neither proven, observed, nor correctly and accurately described until the 17 th century. The reason for this was that all these early studies lacked the microscope. Antonie van Leeuwenhoek — was one of the first people to observe microorganisms, using a microscope of his own design, and made one of the most important contributions to biology.

Microbiology has had a long, rich history, initially centered in the causes of infectious diseases but now including practical applications of the science. Many individuals have made significant contributions to the development of microbiology. Early history of microbiology. He is reputed to have observed strands of fungi among the specimens of cells he viewed. In the s and the decades thereafter, a Dutch merchant named Anton van Leeuwenhoek made careful observations of microscopic organisms, which he called animalcules.

Microbiology: past, present and future

Microbiology begins with the study of bacteria, yeasts, molds, viruses, and parasites - the microbes; how they are isolated, cultivated, and identified. The next level of study considers them as individual living systems, their physiology and genetics. The third level of study, the working level of a modern microbiologist, is concerned with how microbes interact with living and non-living elements and how these interactions may be controlled, modified, or expanded to benefit the environment and humanity. Microbiology majors identifying "unknown pathogens" in Medical Bacteriology lab. Our Bachelor of Arts degree is designed to be flexible, and yet provide disciplinary breadth for pre-professional students and students interested in an entry-level career in microbiology, the life or health sciences, or environmental sciences.

Microbiology , study of microorganisms, or microbes, a diverse group of generally minute simple life-forms that include bacteria , archaea , algae , fungi , protozoa , and viruses. The field is concerned with the structure, function, and classification of such organisms and with ways of both exploiting and controlling their activities. The word microbe was coined in the last quarter of the 19th century to describe these organisms, all of which were thought to be related. As microbiology eventually developed into a specialized science, it was found that microbes are a very large group of extremely diverse organisms. Daily life is interwoven inextricably with microorganisms. 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. Abundant, although usually unnoticed, microorganisms provide ample evidence of their presence—sometimes unfavourably, as when they cause decay of materials or spread diseases, and sometimes favourably, as when they ferment sugar to wine and beer , cause bread to rise, flavour cheeses, and produce valued products such as antibiotics and insulin.

 Ну и что мне, прожевать все эти цифры. Она поправила прическу. - Ты же всегда стремился к большей ответственности. Вот. Он печально на нее посмотрел.

Я, пожалуй, занесу его в полицейский участок по пути в… - Perdon, - прервал его Ролдан, занервничав.  - Я мог бы предложить вам более привлекательную идею.  - Ролдан был человек осторожный, а визит в полицию мог превратить его клиентов в бывших клиентов.  - Подумайте, - предложил.  - Раз у человека в паспорте был наш номер, то скорее всего он наш клиент.

 А знаешь, - Мидж без всякой нужды перешла на шепот, - Джабба сказал, что Стратмор перехватил сообщение террористов за шесть часов до предполагаемого времени взрыва. У Бринкерхоффа отвисла челюсть. - Так почему… чего же он так долго ждал. - Потому что ТРАНСТЕКСТ никак не мог вскрыть этот файл.

Все файлы прошли проверку, в них не было обнаружено ничего необычного, а это означало, что ТРАНСТЕКСТ безукоризненно чист. На что же уходит такая уйма времени. - спросил он, обращаясь в пустоту и чувствуя, как покрывается. Наверное, придется потревожить этой новостью Стратмора. Проверка на наличие вируса, - решительно сказал он себе, стараясь успокоиться.  - Я должен сделать проверку на наличие вируса. Чатрукьян знал: это первое, чего в любом случае потребует Стратмор.

Лет пятнадцати-шестнадцати. Волосы… - Не успев договорить, он понял, что совершил ошибку. Кассирша сощурилась. - Вашей возлюбленной пятнадцать лет. - Нет! - почти крикнул Беккер.  - Я хотел сказать… - Чертовщина.

Никто не сомневался, что АНБ проиграло сражение.
