Understanding the role of different species in the transmission of multi-host pathogens is vital for effective control strategies. In their latest research, Lushasi and colleagues present data from a previously unstudied area of south-east Tanzania following the introduction of large-scale dog vaccination. Rabies is one of the world’s most feared diseases due to its high case fatality rate. Despite the existence of safe and effective … Continue reading Cross-species transmission: what is the role of wildlife in sustaining rabies spread?
In their latest research, Khanyari and colleagues develop a three-step framework to assess cross-species disease transmission risk between migrating wildlife and livestock in data-limited circumstances and across social-ecological scale. Shared use of land between wildlife and livestock can lead to disease transmission, harming agricultural livelihoods and impacting wildlife conservation. This is especially problematic when endangered wildlife live in close proximity to largely resource poor people. … Continue reading A framework to prioritize disease risk between wildlife and livestock
Ryan Sharp and colleagues investigate the answers to both of these questions and discuss their recent work, The effect of competition on the control of invading plant pathogens, published in Journal of Applied Ecology.
When pathogens invade into an area, they may find themselves in competition with already endemic pathogen strains. This competition can severely limit the spread of the invader. Control methods generally do not distinguish between pathogen strains. Therefore, when control is applied, both invasive and endemic strains are affected. Continue reading How can control of invading plant pathogens increase their rate of spread? How can we prevent it?
Infectious diseases have recently been acknowledged as an important threat for wild populations, notably seabirds. In order to implement efficient surveillance and management programmes, it is critical to look beyond the sick individuals to identify the individuals or species involved in cryptic epidemiological processes, such as pathogen spread. Amandine Gamble et al. summarise their recent research on the potential role of predators and scavengers in … Continue reading Predator and scavenger movements as opportunities for pathogen spread among endangered seabirds
Les maladies infectieuses sont depuis peu reconnues comme une menace importante pour les populations sauvages, notamment les oiseaux marins. Afin de mettre en place des mesures de surveillance et de gestion efficaces, il est essentiel de regarder au-delà de l’animal malade pour pouvoir identifier les individus ou espèces impliqués dans les processus épidémiologiques cryptiques, tels que la dissémination d’agents pathogènes. Amandine Gamble et collaborateurs résument … Continue reading Comportement alimentaire des prédateurs et charognards et opportunités pour la dissémination d’agents pathogènes
Our November Editor’s Choice article raises the question of whether the culling of badgers could increase the risk of TB spread in cattle, as badgers in culled areas travel further. Associate Editor, Andrew Park, looks at context and management implications of Ham et al.’s recent findings. Bovine tuberculosis (TB) is an important livestock disease in the UK, where it has been increasing since the 1990s … Continue reading Editor’s Choice 56:11 – badger behaviour compromises TB eradication efforts
Penelope A. Hancock presents recently published work on ‘Predicting the spatial dynamics of Wolbachia infections in Aedes aegypti arbovirus vector populations in heterogeneous landscapes‘. Uncertainty surrounding density-dependent mosquito population growth rates prevents us from predicting the outcome of mosquito control interventions. A timely example is the introduction of Wolbachia bacterial infections into wild Aedes aegypti populations, the major vector of the dengue, Zika and chikungunya … Continue reading The amorphous, heterogeneous spatial spread of Wolbachia
