Gordon Dougan is a professor in the Department of Medicine at the University of Cambridge and head of pathogen research and a member of the board of management at the Wellcome Sanger Institute in Cambridge, United Kingdom. [4] He is also a Fellow of Wolfson College, Cambridge. During his career, Dougan has pioneered work on enteric diseases and been heavily involved in the movement to improve vaccine usage in developing countries. In this regard he was recently voted as one of the top ten most influential people in the vaccine world by people working in the area. [5]
Dougan grew up on a council estate in Scunthorpe [6] and was educated at Henderson Avenue Junior School, Scunthorpe Grammar School and John Leggott College. [1] He graduated with a degree in Biochemistry [2] and received his PhD, both from the University of Sussex. [7]
After his PhD, Dougan completed postdoctoral research at the University of Washington (Seattle) in the laboratory of Professor Stanley Falkow. Dougan's research team studies enteric pathogens with a strong emphasis on basic pathogenic mechanisms and immunology. [8] [9] [10] [11] [12] [13] [14] [15] [16] He has a particular interest in using genomics to study host/pathogens interactions, in particular using Salmonella enterica serovar Typhi, the cause of typhoid. He has extensive experience working both in industry and in academia. Before moving to the WTSI he was the Director of the Centre for Molecular Microbiology and Infection at the Imperial College London and a Professor of Physiological Biochemistry. There he was responsible for securing multimillion-pound funding for a new building in Kensington and providing infrastructure for the science.
Throughout his career Dougan has served as a referee, advisor and consultant for numerous institutions, universities, boards, committees and other organisations. He was a trustee of the International Vaccine Institute in Korea and has worked with other global agencies including the World Health Organization and the Global Alliance for Vaccine and Innovations (now GAVI Alliance).
Dougan was a lecturer in the Moyne Institute in Trinity College, Dublin [ citation needed ] and then worked for over ten years in industry developing vaccines and novel drugs at the Wellcome Foundation (now GlaxoSmithKline GSK). He has participated in early and late clinical studies on several vaccines and is an expert in vaccinology/pathogenic mechanisms, specialising on the immunology of mucosal vaccines and molecular basis of infection. He has been Chair of the Novartis Vaccines & Diagnostics Scientific Advisory Board and has spun out a number of companies. He has published over 400 research papers, edited several books and has sat on the editorial boards of prestigious journals. [11] [17]
Dougan was elected a Fellow of the Royal Society in 2012. His nomination reads:
Gordon Dougan is distinguished through his investigations into how bacteria interact with and stimulate the mucosal surfaces of the body during infection. His work has focused on bacterial pathogens, principally Salmonella Typhi and other enteric bacteria and has exploited genetic manipulation of both the host and pathogen. He has made important contributions to basic studies on the molecular basis of the infection process, genomics and to the development of practical vaccines. [18]
Dougan was elected a member of the European Molecular Biology Organization (EMBO) in 2011. [3] He was elected a Fellow of the Academy of Medical Sciences (FMedSci) in 2002. [19] [20]
Dougan has been a lifelong supporter of Scunthorpe United [ citation needed ] and is an experienced beekeeper. [21]
Typhoid fever, also known simply as typhoid, is a disease caused by Salmonella enterica serotype Typhi bacteria, also called Salmonella typhi. Symptoms vary from mild to severe, and usually begin six to 30 days after exposure. Often there is a gradual onset of a high fever over several days. This is commonly accompanied by weakness, abdominal pain, constipation, headaches, and mild vomiting. Some people develop a skin rash with rose colored spots. In severe cases, people may experience confusion. Without treatment, symptoms may last weeks or months. Diarrhea may be severe, but is uncommon. Other people may carry it without being affected, but are still contagious. Typhoid fever is a type of enteric fever, along with paratyphoid fever. Salmonella enterica Typhi is believed to infect and replicate only within humans.
Salmonella is a genus of rod-shaped (bacillus) gram-negative bacteria of the family Enterobacteriaceae. The two known species of Salmonella are Salmonella enterica and Salmonella bongori. S. enterica is the type species and is further divided into six subspecies that include over 2,650 serotypes. Salmonella was named after Daniel Elmer Salmon (1850–1914), an American veterinary surgeon.
Salmonella enterica is a rod-shaped, flagellate, facultative anaerobic, Gram-negative bacterium and a species of the genus Salmonella. It is divided into six subspecies, arizonae (IIIa), diarizonae (IIIb), houtenae (IV), salamae (II), indica (VI), and enterica (I). A number of its serovars are serious human pathogens; many of them are serovars of Salmonella enterica subsp. enterica.
Salmonellosis is a symptomatic infection caused by bacteria of the Salmonella type. It is the most common disease to be known as food poisoning, these are defined as diseases, usually either infectious or toxic in nature, caused by agents that enter the body through the ingestion of food. In humans, the most common symptoms are diarrhea, fever, abdominal cramps, and vomiting. Symptoms typically occur between 12 hours and 36 hours after exposure, and last from two to seven days. Occasionally more significant disease can result in dehydration. The old, young, and others with a weakened immune system are more likely to develop severe disease. Specific types of Salmonella can result in typhoid fever or paratyphoid fever. Typhoid fever and paratyphoid fever are specific types of salmonellosis, known collectively as enteric fever, and are, respectively, caused by salmonella typhi and paratyphi bacteria, which are only found in humans. Most commonly, salmonellosis cases arise from salmonella bacteria from animals, and chicken is a major source for these infections.
The Wellcome Sanger Institute, previously known as The Sanger Centre and Wellcome Trust Sanger Institute, is a non-profit British genomics and genetics research institute, primarily funded by the Wellcome Trust.
A serotype or serovar is a distinct variation within a species of bacteria or virus or among immune cells of different individuals. These microorganisms, viruses, or cells are classified together based on their surface antigens, allowing the epidemiologic classification of organisms to a level below the species. A group of serovars with common antigens is called a serogroup or sometimes serocomplex.
Paratyphoid fever, also known simply as paratyphoid, is a bacterial infection caused by one of three types of Salmonella enterica. Symptoms usually begin 6–30 days after exposure and are the same as those of typhoid fever. Often, a gradual onset of a high fever occurs over several days. Weakness, loss of appetite, and headaches also commonly occur. Some people develop a skin rash with rose-colored spots. Without treatment, symptoms may last weeks or months. Other people may carry the bacteria without being affected; however, they are still able to spread the disease to others. Typhoid and paratyphoid are of similar severity. Paratyphoid and typhoid fever are types of enteric fever.
Ty21a is a live attenuated bacterial vaccine that protects against typhoid. First licensed in Europe in 1983 and in the United States in 1989, it is an orally administered, live-attenuated Ty2 strain of S. Typhi in which multiple genes, including the genes responsible for the production of Vi, have been deleted so as to render it harmless but nevertheless immunogenic. It is one of the three typhoid vaccines currently recommended by the World Health Organization.
Pathogenomics is a field which uses high-throughput screening technology and bioinformatics to study encoded microbe resistance, as well as virulence factors (VFs), which enable a microorganism to infect a host and possibly cause disease. This includes studying genomes of pathogens which cannot be cultured outside of a host. In the past, researchers and medical professionals found it difficult to study and understand pathogenic traits of infectious organisms. With newer technology, pathogen genomes can be identified and sequenced in a much shorter time and at a lower cost, thus improving the ability to diagnose, treat, and even predict and prevent pathogenic infections and disease. It has also allowed researchers to better understand genome evolution events - gene loss, gain, duplication, rearrangement - and how those events impact pathogen resistance and ability to cause disease. This influx of information has created a need for bioinformatics tools and databases to analyze and make the vast amounts of data accessible to researchers, and it has raised ethical questions about the wisdom of reconstructing previously extinct and deadly pathogens in order to better understand virulence.
Salmonella enterica subsp. enterica is a subspecies of Salmonella enterica, the rod-shaped, flagellated, aerobic, Gram-negative bacterium. Many of the pathogenic serovars of the S. enterica species are in this subspecies, including that responsible for typhoid.
Salmonella bongori is a pathogenic bacterium belonging to the genus Salmonella, and was earlier known as Salmonella subspecies V or S. enterica subsp. bongori or S. choleraesuis subsp. bongori. It is a Gram-negative, rod-shaped bacterium (bacillus), which causes a gastrointestinal disease called salmonellosis, characterized by cramping and diarrhoea. It is typically considered a microbe of cold-blooded animals, unlike other members of the genus, and is most frequently associated with reptiles.

Host-directed therapeutics, also called host targeted therapeutics, act via a host-mediated response to pathogens rather than acting directly on the pathogen, like traditional antibiotics. They can change the local environment in which the pathogen exists to make it less favorable for the pathogen to live and/or grow. With these therapies, pathogen killing, e.g.bactericidal effects, will likely only occur when it is co-delivered with a traditional agent that acts directly on the pathogen, such as an antibiotic, antifungal, or antiparasitic agent. Several antiviral agents are host-directed therapeutics, and simply slow the virus progression rather than kill the virus. Host-directed therapeutics may limit pathogen proliferation, e.g., have bacteriostatic effects. Certain agents also have the ability to reduce bacterial load by enhancing host cell responses even in the absence of traditional antimicrobial agents.
