| weather variability, tides, and barmah forest virus disease in the gladstone region, australia. | in this study we examined the impact of weather variability and tides on the transmission of barmah forest virus (bfv) disease and developed a weather-based forecasting model for bfv disease in the gladstone region, australia. we used seasonal autoregressive integrated moving-average (sarima) models to determine the contribution of weather variables to bfv transmission after the time-series data of response and explanatory variables were made stationary through seasonal differencing. we obtained ... | 2006 | 16675420 |
| predicting the timing and magnitude of tropical mosquito population peaks for maximizing control efficiency. | the transmission of mosquito-borne diseases is strongly linked to the abundance of the host vector. identifying the environmental and biological precursors which herald the onset of peaks in mosquito abundance would give health and land-use managers the capacity to predict the timing and distribution of the most efficient and cost-effective mosquito control. we analysed a 15-year time series of monthly abundance of aedes vigilax, a tropical mosquito species from northern australia, to determine ... | 2009 | 19238191 |
| development and field evaluation of the sentinel mosquito arbovirus capture kit (smack). | although sentinel animals are used successfully throughout the world to monitor arbovirus activity, ethical considerations and cross-reactions in serological assays highlight the importance of developing viable alternatives. here we outline the development of a passive sentinel mosquito arbovirus capture kit (smack) that allows for the detection of arboviruses on honey-baited nucleic acid preservation cards (flinders technology associates; fta®) and has a similar trap efficacy as standard light ... | 2015 | 26444264 |
| spatial and temporal patterns of locally-acquired dengue transmission in northern queensland, australia, 1993-2012. | dengue has been a major public health concern in australia since it re-emerged in queensland in 1992-1993. we explored spatio-temporal characteristics of locally-acquired dengue cases in northern tropical queensland, australia during the period 1993-2012. | 2014 | 24691549 |
| oviposition and larval habitat preferences of the saltwater mosquito, aedes vigilax, in a subtropical mangrove forest in queensland, australia. | our aim was to investigate the oviposition and larval habitats of the saltwater mosquito aedes vigilax (skuse) (diptera: culicidae) in a mangrove forest system in subtropical queensland, australia. eggshells (indicators of oviposition) and larvae were sampled in three habitat classes that were depicted in a schematic model. two classes were in depressions or basins, either with hummocks or dense pneumatophore substrates, both of which retained water after tidal flooding. the third class was in f ... | 0 | 22938052 |
| a new insect-specific flavivirus from northern australia suppresses replication of west nile virus and murray valley encephalitis virus in co-infected mosquito cells. | recent reports of a novel group of flaviviruses that replicate only in mosquitoes and appear to spread through insect populations via vertical transmission have emerged from around the globe. to date, there is no information on the presence or prevalence of these insect-specific flaviviruses (isfs) in australian mosquito species. to assess whether such viruses occur locally, we used reverse transcription-polymerase chain reaction (rt-pcr) and flavivirus universal primers that are specific to the ... | 2013 | 23460804 |
| foraging ranges of insectivorous bats shift relative to changes in mosquito abundance. | the need to develop effective management strategies for insectivorous bat populations requires an understanding of factors influencing habitat use. availability of pest prey, such as mosquitoes is likely to be one such factor. to assess whether this is the case, we radio-tracked vespadelus vulturnus thomas (little forest bat), a predator of aedes vigilax skuse (saltmarsh mosquito), in saltmarsh and adjacent coastal swamp forest during periods of high and low ae. vigilax abundance. when mosquito ... | 2013 | 23667699 |
| spatio-temporal patterns of barmah forest virus disease in queensland, australia. | barmah forest virus (bfv) disease is a common and wide-spread mosquito-borne disease in australia. this study investigated the spatio-temporal patterns of bfv disease in queensland, australia using geographical information system (gis) tools and geostatistical analysis. | 2011 | 22022430 |
| west nile virus (kunjin subtype) disease in the northern territory of australia--a case of encephalitis and review of all reported cases. | west nile virus kunjin subtype (wnv/kunv) is enzootic across the tropical north of australia, with epizootic spread into other jurisdictions. the clinical spectrum of illness in humans is poorly described. we report a clinical case of wnv/kunv encephalitis and performed a retrospective chart audit of all cases of wnv/kunv notified in the northern territory from 1992 to 2010. thirteen cases of wnv/kunv disease were identified; case notes were available for 10 of these presentations. six of these ... | 2011 | 22049056 |
| mhc class ii diversity of koala (phascolarctos cinereus) populations across their range. | major histocompatibility complex class ii (mhcii) genes code for proteins that bind and present antigenic peptides and trigger the adaptive immune response. we present a broad geographical study of mhcii da β1 (dab) and db β1 (dbb) variants of the koala (phascolarctos cinereus; n=191) from 12 populations across eastern australia, with a total of 13 dab and 7 dbb variants found. we identified greater mhcii variation and, possibly, additional gene copies in koala populations in the north (queensla ... | 2014 | 24690756 |
| habitat characteristics and eggshell distribution of the salt marsh mosquito, aedes vigilax, in marshes in subtropical eastern australia. | research at 10 locations in coastal subtropical queensland, australia, has shown that salt marshes contained heterogeneous distributions of eggshells of the pest and vector mosquito aedes vigilax (skuse) (diptera:culicidae). the eggshell distribution was related to specific vegetation assemblages, with a mix of the grass, sporobolus virginicus (l.) kunth (poales: poaceae), and the beaded glasswort, sarcocornia quinqueflora (bunge ex (ung.-stern) a.j. scott (caryophyllales: chenopodiaceae), as si ... | 0 | 20233077 |
| bayesian classification and regression trees for predicting incidence of cryptosporidiosis. | classification and regression tree (cart) models are tree-based exploratory data analysis methods which have been shown to be very useful in identifying and estimating complex hierarchical relationships in ecological and medical contexts. in this paper, a bayesian cart model is described and applied to the problem of modelling the cryptosporidiosis infection in queensland, australia. | 2011 | 21909377 |
