Pourtant, un virus n’effectue pas de « sauts d’hôte » aussi aisément que l’on pourrait l’imaginer. L’analyse de ce phénomène a été menée par Jacques Tassin, chercheur en écologie forestière et Jean-Marc Roda, chercheur en économie (tous deux au Cirad : Centre de coopération internationale en recherche agronomique pour le développement).

Efforts to identify the geographic origins and underlying causes of disease emergence are essential to move interventions closer to the source, more effectively limiting subsequent impacts. A previous study (Jones et al., 2008) used logistic regression to model the association between “EID events” and various factors, and found different distribution and driver associations for different categories of EID event.

The Dynamic Drivers of Disease in Africa Consortium is a research program that works to understand the relationships between ecosystems, zoonotic diseases, health and wellbeing in order to inform effective public health interventions. Under this program, multidisciplinary country teams are studying four zoonotic diseases: henipavirus infection in Ghana, Lassa fever in Sierra Leone, Rift Valley fever in Kenya and trypanosomiasis in Zambia and Zimbabwe. The focus is on how changes in biodiversity, land use and climate affect disease transmission. The development of irrigation schemes is thought to influence pathogen transmission in people and animals in several ways.

ECOLOGY LETTERS 11/03/13 A meta‐analysis suggesting that the relationship between biodiversity and risk of zoonotic pathogen transmission is idiosyncratic. Introduction Zoonotic pathogens – disease agents such as the SARS coronavirus, Lyme disease spirochete or West Nile virus, which are transmitted to humans from non‐human animals – are significant burdens on global public health (Jones et al . 2008).

ECOLOGY LETTERS 11/03/13 A meta‐analysis suggesting that the relationship between biodiversity and risk of zoonotic pathogen transmission is idiosyncratic

Zoonotic transmission is inherently a multi‐species phenomenon, often also involving vector intermediaries, making an understanding of underlying ecological processes essential for management and control. Indeed, a key question in disease ecology and epidemiology is how to mitigate or ameliorate pathogen transmission from wildlife reservoirs to human populations. The ‘dilution effect’ hypothesis, which suggests that disease risk will decrease as a result of increased species diversity, offers an intriguing possibility of harnessing conservation initiatives in order to reduce disease risk to human populations (Pongsiri et al . 2009; Keesing et al . 2010).

Pour l'écologue Franck Courchamp, l'humain favorise lui-même ce genre de catastrophe en appauvrissant les ressources et en dégradant la biodiversité dont les parasites font partie intégrante. Cet entretien paru en mai fait partie des 10 contenus les plus vus cette année sur notre site. Les écologues se sont-ils toujours intéressés aux parasites, en général, et aux virus, en particulier ? Franck Courchamp1 : L’omniprésence du parasitisme (la relation entre deux êtres vivants dont l’un vit aux dépens de l’autre), de même que son impact sur les populations animales et végétales, les espèces et les écosystèmes, a longtemps été sous-estimée par les chercheurs en écologie. Il faut dire qu’un lion qui dévore une antilope, ça se voit, tandis que les parasites de cette antilope, et leurs effets, sont souvent invisibles (le lion tue souvent l’antilope avant que sa maladie ne soit facilement observable).

Clinical Microbiology and Infection Volume 15, Supplement 1, January 2009, Biodiversity loss and the rise of zoonotic pathogens

Although the ability of scientists to ascertain how many species have or will soon become extinct varies considerably among taxonomic groups and ecosystem types, it is clear that the current extinction crisis is pervasive, even universal. At current rates, global extinctions within some classes of vertebrates are predicted to approach 50% within about 100 years [5]. Even more pervasive, yet more poorly documented, are local extinctions of populations and metapopulations.

Although the ability of scientists to ascertain how many species have or will soon become extinct varies considerably among taxonomic groups and ecosystem types, it is clear that the current extinction crisis is pervasive, even universal. At current rates, global extinctions within some classes of vertebrates are predicted to approach 50% within about 100 years [5]. Even more pervasive, yet more poorly documented, are local extinctions of populations and metapopulations. The consequences of this loss of biodiversity for humanity are certainly going to be profound [4]. Many species produce chemical compounds that are usable or adaptable as pharmaceutical agents to the direct benefit of human health.

These benefits are termed “ecosystem services” and encompass the wide range of resources and processes that regulate the environment, provide food, materials and cultural stimulation and contribute to other ecosystem services. One such suggested ecosystem service is that diverse ecosystems may reduce the risk of zoonosis (pathogen transmitted from animals to humans). The underlying concept is that vertebrate hosts differ in their relative competence as transmission hosts of vector-borne pathogens, consequently, the distribution of vectors among host species will affect the transmission potential of pathogens. For example, if a large proportion of the vector population feeds solely on non-competent transmission hosts then the pathogen is unlikely to persist within that system (R0<1).
