To determine the true community prevalence of human cystic (CE) and alveolar (AE) echinococcosis (hydatid disease) in a highly endemic region Ningxia Hui, China, by detecting asymptomatic cases.Using hospital records "AE-risk" landscape patterns we selected study communities predicted to be at risk Guyuan, Longde Xiji counties. We conducted surveys 4773 individuals from 26 villages 2002 2003 using questionnaire analysis, ultrasound examination serology.Ultrasound serology showed range...
Human alveolar echinococcocosis (AE) is a highly pathogenic zoonotic disease caused by the larval stage of cestode E. multilocularis. Its life-cycle includes more than 40 species small mammal intermediate hosts. Therefore, host biodiversity losses could be expected to alter transmission. Climate may also have possible impacts on multilocularis egg survival. We examined distribution human AE across two spatial scales, (i) for continental China and (ii) over eastern edge Tibetan plateau....
Summary Pest control is a global issue for agriculture, health, biodiversity conservation and economy. Anticoagulant rodenticides are used over large areas to rodent pests can cause widespread poisoning of nontarget wildlife. In F rance, bromadiolone the only pesticide authorized water vole A rvicola terrestris S cherman, in grasslands. Since 2001, legislation has been place replace curative treatments by preventive ones limit quantity rodenticide used. As took effect time, impact on red fox...
Characterising the spatio-temporal dynamics of pathogens in natura is key to ensuring their efficient prevention and control. However, it notoriously difficult estimate dispersal parameters at scales that are relevant real epidemics. Epidemiological surveys can provide informative data, but parameter estimation be hampered when timing epidemiological events uncertain, presence interactions between disease spread, surveillance, Further complications arise from imperfect detection huge number...
Background Alveolar echinococcosis (AE) presents a serious public health challenge within China. Mass screening ultrasound surveys can detect pre-symptomatic AE, but targeting areas identified from hospital records is inefficient regarding AE. Prediction of undetected or emerging hotspots would increase detection rates. Voles and lemmings the subfamily Arvicolinae are important intermediate hosts in sylvatic transmission systems. Their populations reach high densities productive grasslands...
Abstract Various mosquito control methods use factory raised males to suppress vector densities. But the efficiency of these is currently insufficient prevent epidemics arbovirus diseases such as dengue, chikungunya or Zika. Suggestions that sterile insect technique (SIT) could be “boosted” by applying biopesticides remain unquantified. Here, we assess mathematically gains SIT for Aedes either: boosting with pupicide pyriproxifen (BSIT); or, contaminating mosquitoes at auto-dissemination...
Risk factors for the transmission of Echinococcus multilocularis to humans operate at a range spatial scales. Over large area, such as China, regional scale risk is correlated with variation in climatic conditions because its effect on distribution landscapes that can support E. wildlife hosts and probability egg survival. At local few kilometres, or tens related proximity human populations active transmission. patch scale, when considering individual villages households, behavioural are...
Identifying the key factors underlying spread of a disease is an essential but challenging prerequisite to design management strategies. To tackle this issue, we propose approach based on sensitivity analyses spatiotemporal stochastic model simulating plant epidemic. This work motivated by sharka, caused plum pox virus, in real landscape. We first carried out broad-range analysis, ignoring any prior information six epidemiological parameters, assess their intrinsic influence behaviour. A...
Deforestation is a major environmental issue driving the loss of animal and plant species. Afforestation has recently been promoted to conserve restore Chinese forest ecosystems. We investigated distribution small-mammal assemblages in an area where associated deforestation habitats dominate, agricultural afforestation ongoing Loess Plateau southern Ningxia Autonomous Region, P.R. China. Multiple trapping was used. Assemblages were defined based on multinomial probability information theory....
Over the last decade African swine fever virus, one of most virulent pathogens known to affect pigs, has devastated pork industries and wild pig populations throughout world. Despite a growing literature on specific aspects transmission dynamics, it remains unclear which methods approaches are effective for controlling disease during crisis. As consequence, an international modelling challenge was organized in teams analyzed responded stream data from silico outbreak fictive country Merry...
Amblyomma variegatum and A. hebraeum are two ticks of veterinary human health importance in south-east Africa. In Zimbabwe they occupy parapatric (marginally overlapping juxtaposed) distributions. Understanding the mechanisms behind this parapatry is essential for predicting spatio-temporal dynamics spp. impacts associated diseases. It has been hypothesized that exclusive competition between these species results from at levels male signal reception (attraction-aggregation-attachment...
Summary Outbreaks of the water vole Arvicola terrestris cause severe damage in grasslands upland regions Europe. The sheer speed this phenomenon is a challenge to effective pest control measures. While there has been some research into factors that promote outbreaks, especially landscape composition, little yet known biological mechanisms underlying colonization during population growth stage. Like A. , mole Talpa europaea digs vast tunnel networks may be used by . availability extensive...
Vaccination is one of the most efficient ways to control spread infectious diseases. Simulations are now widely used assess how vaccination can limit disease as well mitigate morbidity or mortality in susceptible populations. However, field studies investigating much vaccines decrease velocity epizootic wave-fronts during outbreaks rare. This study aimed at effect on propagation bluetongue, a vector-borne ruminants. We data from 2008 bluetongue virus serotype 1 (BTV-1) southwest France. As...
Since 1976 various species of Ebolavirus have caused a series zoonotic outbreaks and public health crises in Africa. Bats long been hypothesised to function as important hosts for ebolavirus maintenance, however the transmission ecology these viruses remains poorly understood. Several studies demonstrated rapid seroconversion antibodies young bats, yet paradoxically few PCR confirmed identity circulating viral causing seroconversions. The current study presents an age-structured...
Determining how reproductive barriers modulate gene flow between populations represents a major step toward understanding the factors shaping course of speciation. Although many indices quantifying isolation (RI) have been proposed, they do not permit quantification cross-direction-specific RI under varying species frequencies and over arbitrary sequences barriers. Furthermore, techniques associated uncertainties are lacking, statistical methods unrelated to biological process still...
