Given the question: Information: - Biotechnology is the use of living systems and organisms to develop or make products, or "any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use" (UN Convention on Biological Diversity, Art. 2). Depending on the tools and applications, it often overlaps with the (related) fields of bioengineering, biomedical engineering, biomanufacturing, molecular engineering, etc. - Virology is the study of viruses submicroscopic, parasitic particles of genetic material contained in a protein coat and virus-like agents. It focuses on the following aspects of viruses: their structure, classification and evolution, their ways to infect and exploit host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they cause, the techniques to isolate and culture them, and their use in research and therapy. Virology is considered to be a subfield of microbiology or of medicine. - Bioinformatics is an interdisciplinary field that develops methods and software tools for understanding biological data. As an interdisciplinary field of science, bioinformatics combines computer science, statistics, mathematics, and engineering to analyze and interpret biological data. Bioinformatics has been used for "in silico" analyses of biological queries using mathematical and statistical techniques. - Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City. Italy covers an area of and has a largely temperate seasonal climate and Mediterranean climate; due to its shape, it is often referred to in Italy as "lo Stivale" (the Boot). With 61 million inhabitants, it is the fourth most populous EU member state. - Immunology is a branch of biology that covers the study of immune systems in all organisms. It was the Russian biologist Ilya Ilyich Mechnikov who boosted studies on immunology, and received the Nobel Prize in 1908 for his work. He jabbed the thorn of a rose on a starfish and noted that, 24 hours later, cells were surrounding the tip. It was an active response of the body, trying to maintain its integrity. It was Mechnikov who first observed the phenomenon of phagocytosis, in which the body defends itself against a foreign body, and coined the term. It charts, measures, and contextualizes the: physiological functioning of the immune system in states of both health and diseases; malfunctions of the immune system in immunological disorders (such as autoimmune diseases, hypersensitivities, immune deficiency, and transplant rejection); the physical, chemical and physiological characteristics of the components of the immune system "in vitro", "in situ," and "in vivo". Immunology has applications in numerous disciplines of medicine, particularly in the fields of organ transplantation, oncology, virology, bacteriology, parasitology, psychiatry, and dermatology. - The term "microbiologist" comes from the Greek "mkros" meaning "small" , and "bios", meaning "life" , combined with "-logia" meaning one who studies. A microbiologist (from Greek ) is a biological scientist who studies microscopic life forms and processes or works in the field of microbiology. Microbiologists investigate the growth, interactions and characteristics of microscopic organisms such as bacteria, algae, fungi, and some types of parasites and their vectors. They contribute much to the field by trying to understand and learn about the interaction between these microbes and the environment and also among themselves and other organisms. Most microbiologists are qualified to work in offices and/or research facilities, such as a laboratory as well as in the academia. There, they conduct experiments that help them analyze microbes and their importance. A microbiologist's work is often repeated or improved in order to establish accurate research. Most microbiologists specialize in environmental, food, agricultural, industrial or medical aspects of microbiology including: virology (the study of viruses); immunology (the study of mechanisms that fight infections); bioinformatics (the methods for storing, retrieving, organizing and analyzing biological data) and Bioremediation (using microbes as environmental mitigation strategies). Many microbiologists use biotechnology to advance the understanding of cell reproduction and human disease. Some microbiologists have contributed to knowledge of pathogens and disease-causing microbes. While others, study their interaction with the environment and their use as potential environmental pollution cleaners. - Adelchi Negri ( 2 August 1876 -- 19 February 1912 ) was an Italian pathologist and microbiologist born in Perugia . He studied medicine and surgery at the University of Pavia , where he was a pupil of Camillo Golgi ( 1843 -- 1926 ) . After graduation in 1900 , he became an assistant to Golgi at his pathological institute . In 1909 Negri became a professor of bacteriology , and the first official instructor of bacteriology in Pavia . On February 19 , 1912 he died of tuberculosis at age 35 . Negri performed extensive research in the fields of histology , hematology , cytology , protozoology and hygiene . In 1903 he discovered the eponymous Negri bodies , defined as cytoplasmatic inclusion bodies located in the Purkinje cells of the cerebellum in cases of rabies in animals and humans . He documented his findings in an article titled Contributo allo studio dell'eziologia della rabia , published in the journal Bollettino della Societa medico - chirurgica . At the time , Negri mistakenly described the pathological agent of rabies as a parasitic protozoa . A few months later , Paul Remlinger ( 1871 -- 1964 ) at the Constantinople Imperial Bacteriology Institute correctly demonstrated that the aetiological agent of rabies was not a protozoan , but a filterable virus . Negri went on , however , to demonstrate in 1906 that the smallpox vaccine , then known as '' vaccine virus '' , or '' variola vaccinae '' , was also a filterable virus . During the latter part of his career , he became interested in malaria and was at the forefront in efforts to eradicate it from Lombardy . - Life is a characteristic distinguishing physical entities having biological processes, such as signaling and self-sustaining processes, from those that do not, either because such functions have ceased, or because they never had such functions and are classified as inanimate. Various forms of life exist, such as plants, animals, fungi, protists, archaea, and bacteria. The criteria can at times be ambiguous and may or may not define viruses, viroids, or potential artificial life as "living". Biology is the primary science concerned with the study of life, although many other sciences are involved. - Perugia is the capital city of both the region of Umbria in central Italy, crossed by the river Tiber, and of the province of Perugia. The city is located about north of Rome and south-east of Florence. It covers a high hilltop and part of the valleys around the area. The region of Umbria is bordered by Tuscany, Lazio, and Marche. The history of Perugia goes back to the Etruscan period; Perugia was one of the main Etruscan cities. The city is also known as the universities town, with the University of Perugia founded in 1308 (about 34,000 students), the University for Foreigners (5,000 students), and some smaller colleges such the Academy of Fine Arts "Pietro Vannucci" public athenaeum founded in 1573, the Perugia University Institute of Linguistic Mediation for translators and interpreters, the Music Conservatory of Perugia, founded in 1788, and others Institutes.
