Exploring the involvement of honey bee pathogens in colony collapses from epidemiological data, pathogen genotyping and host immune responses Universiteit Gent
Morphological, Pathogenic and Toxigenic Variability in the Rice Sheath Rot Pathogen Sarocladium Oryzae Universiteit Gent
Multiphasic investigations imply transfer of orange-/red-pigmented strains of the bean pathogen Curtobacterium flaccumfaciens pv. flaccumfaciens to a new species as C. aurantiacum sp. nov., elevation of the poinsettia pathogen C. flaccumfaciens pv. poinse Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
Curtobacterium flaccumfaciens (Microbacteriaceae), a plant-pathogenic coryneform species includes five pathovars with valid names and a number of proposed – but unvalidated – new members. In this study, phenotypic features and DNA similarity indexes were investigated among all C. flaccumfaciens members. Results showed that the C. flaccumfaciens pv. poinsettiae strains causing bacterial canker of Euphorbia pulcherrima in the USA as well as the ...
New SNP markers for the genetic characterization of the quarantine pathogen Puccinia horiana and their application in pathogen migration analysis Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
The quarantine pathogen Puccinia horiana, causal agent of chrysanthemum white rust, is one of the most important diseases in chrysanthemum-producing regions worldwide. During this study we determined the genetic variability of forty five isolates originating from North and South America, Asia, and Europe based on neutral SNP-markers. Together with information on collection year and geographical origin this allowed us to address ...
Effective methods of estimation of pathogen prevalence in pooled ticks Instituut voor Tropische Geneeskunde Universiteit Antwerpen
Since tick-borne diseases (TBDs) incidence, both in human and animal populations, is increasing worldwide, there is the need to assess the presence, distribution and prevalence of tick-borne pathogens. Reliable estimates on tick-borne pathogens (TBPs) prevalence represent the public health foundation to create risk maps and take effective prevention and control actions against TBDs. Tick surveillance consists of collecting and testing (usually ...
Effect of rodent density on tick and tick-borne pathogen populations: consequences for infectious disease risk Universiteit Hasselt
Background Rodents are considered to contribute strongly to the risk of tick-borne diseases by feeding Ixodes ricinus larvae and by acting as amplifying hosts for pathogens. Here, we tested to what extent these two processes depend on rodent density, and for which pathogen species rodents synergistically contribute to the local disease risk, i.e. the density of infected nymphs (DIN). Methods In a natural woodland, we manipulated rodent densities ...
The impact of mass-flowering crops on bee pathogen dynamics Universiteit Gent
Nearly two fifths of the Earth's land area is currently used for agriculture, substantially impacting the environment and ecosystems. Besides the direct impact through land use change, intensive agriculture can also have an indirect impact, for example by changing wildlife epidemiology. We review here the potential effects of mass-flowering crops (MFCs), which are rapidly expanding in global cropping area, on the epidemiology of known pathogens ...
Epidemic growth rates and host movement patterns shape management performance for pathogen spillover at the wildlife-livestock interface Universiteit Hasselt
Managing pathogen spillover at the wildlife-livestock interface is a key step towards improving global animal health, food security and wildlife conservation. However, predicting the effectiveness of management actions across host-pathogen systems with different life histories is an on-going challenge since data on intervention effectiveness are expensive to collect and results are system-specific. We developed a simulation model to explore how ...
