    Description: The majority of pathogens, including many of medical and veterinary importance, can infect more than one species of host. Population biology has yet to explain why perceived evolutionary advantages of pathogen specialization are, in practice, outweighed by those of generalization. Factors that predispose pathogens to generalism include high levels of genetic diversity and abundant opportunities for cross-species transmission, and the taxonomic distributions of generalists and specialists appear to reflect these factors. Generalism also has consequences for the evolution of virulence and for pathogen epidemiology, making both much less predictable. The evolutionary advantages and disadvantages of generalism are so finely balanced that even closely related pathogens can have very different host range sizes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Woolhouse, M E -- Taylor, L H -- Haydon, D T -- New York, N.Y. -- Science. 2001 May 11;292(5519):1109-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Tropical Veterinary Medicine, University of Edinburgh, Easter Bush, Roslin, Midlothian EH25 9RG, UK. mark.woolhouse@ed.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11352066" target="_blank"〉PubMed〈/a〉

    Description: Foot-and-mouth is one of the world's most economically important livestock diseases. We developed an individual farm-based stochastic model of the current UK epidemic. The fine grain of the epidemiological data reveals the infection dynamics at an unusually high spatiotemporal resolution. We show that the spatial distribution, size, and species composition of farms all influence the observed pattern and regional variability of outbreaks. The other key dynamical component is long-tailed stochastic dispersal of infection, combining frequent local movements with occasional long jumps. We assess the history and possible duration of the epidemic, the performance of control strategies, and general implications for disease dynamics in space and time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keeling, M J -- Woolhouse, M E -- Shaw, D J -- Matthews, L -- Chase-Topping, M -- Haydon, D T -- Cornell, S J -- Kappey, J -- Wilesmith, J -- Grenfell, B T -- New York, N.Y. -- Science. 2001 Oct 26;294(5543):813-7.

    Description: The global epidemic of multidrug-resistant Salmonella Typhimurium DT104 provides an important example, both in terms of the agent and its resistance, of a widely disseminated zoonotic pathogen. Here, with an unprecedented national collection of isolates collected contemporaneously from humans and animals and including a sample of internationally derived isolates, we have used whole-genome sequencing to dissect the phylogenetic associations of the bacterium and its antimicrobial resistance genes through the course of an epidemic. Contrary to current tenets supporting a single homogeneous epidemic, we demonstrate that the bacterium and its resistance genes were largely maintained within animal and human populations separately and that there was limited transmission, in either direction. We also show considerable variation in the resistance profiles, in contrast to the largely stable bacterial core genome, which emphasizes the critical importance of integrated genotypic data sets in understanding the ecology of bacterial zoonoses and antimicrobial resistance.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4012302/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4012302/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mather, A E -- Reid, S W J -- Maskell, D J -- Parkhill, J -- Fookes, M C -- Harris, S R -- Brown, D J -- Coia, J E -- Mulvey, M R -- Gilmour, M W -- Petrovska, L -- de Pinna, E -- Kuroda, M -- Akiba, M -- Izumiya, H -- Connor, T R -- Suchard, M A -- Lemey, P -- Mellor, D J -- Haydon, D T -- Thomson, N R -- 098051/Wellcome Trust/United Kingdom -- 260864/European Research Council/International -- AI107034/AI/NIAID NIH HHS/ -- HG006139/HG/NHGRI NIH HHS/ -- R01 AI107034/AI/NIAID NIH HHS/ -- R01 GM086887/GM/NIGMS NIH HHS/ -- R01 HG006139/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2013 Sep 27;341(6153):1514-7. doi: 10.1126/science.1240578.
