Competition for food reduces disease susceptibility in a marine invertebrate
Provedor de dados: 5
Autores: Pernet, Fabrice; Lugue, Klervi; Petton, Bruno.
Competition between organisms interfere in host and pathogen dynamics in ways that are difficult to predict. By one side, competitors can reduce the food supply and cause nutritional stress. Such stress could further modulate the susceptibility to infection by altering immune response or metabolic rate of the host. Alternatively, competitors may trap pathogens before they reach the focal host, and therefore reduce, enhance, or have no effect on infection according to the competitor's susceptibility to the infection. To better understand how competition influences host and pathogen interactions, we experimentally assessed the relative importance of competition for pathogens and resources on the severity of a viral disease infecting the Pacific oyster...

On the interference of clinical outcome on rabies transmission an perpetuation
Provedor de dados: 80
Autores: Brandão,PE.
Rabies is a viral zoonotic infectious disease that affects mammals and is caused by genotypes/species of the Lyssavirus genus (Rhabdoviridae, Mononegavirales), with the genotype 1 (classic rabies virus - RABV) being the most prevalent. Despite continuous efforts, rabies is still an incurable disease that causes thousands of deaths amongst humans worldwide. Due to a wide range of hosts and the different evolutionary paths of RABV in each host, several host-specific variants have arisen in an ongoing process. The result of RABV replication in nervous tissues may lead to two opposite clinical outcomes, i.e., paralytic/dumb form and encephalitic/furious one. The paralytic form creates dead-end hosts mainly amongst herbivores, while the furious form of the...

Disease and Behavioral Dynamics for Brucellosis Control in Elk and Cattle in the Greater Yellowstone Area
Provedor de dados: 31
Autores: Xie,   Fang; Horan,   Richard D.
This paper investigates private responses and ecological impacts of policies proposed to confront the problem of brucellosis being spread from elk to cattle in Wyoming.  The policies consist of combinations of changes in elk feeding and population levels.  Farmers’ responses to these dynamics are modeled along with the associated impacts to livestock population dynamics. Our findings suggest that feedbacks between jointly determined disease dynamics and decentralized economic behavior matter, and the elk feedgrounds do not actually generate economic harm to the individual farmers.

Optimal Control of Brucellosis in Bison  in the Yellowstone National Park Area
Provedor de dados: 31
Autores: Xie,   Fang; Horan,   Richard D.
Brucellosis is a highly infectious bacterial disease that causes infected females to abort their calves.  It has caused devastating losses to U.S. farmers over the last century. The only known focus of Brucellosis left in the nation is wildlife such as bison and elk in the Greater Yellowstone Area. Vaccination and test-and-slaughter have been applied to brucellosis management in bison, and there has been discussion that a combination of both could potentially eradicate the disease in the Yellowstone National Park. However, there is no study on how to allocate resources between the two actions. This paper investigates the optimal allocation of these two selective management options, in a bioeconomic framework, when there are both existence and recreational...
