| using next-generation sequencing for dna barcoding: capturing allelic variation in its2. | internal transcribed spacer 2 (its2) is a popular dna barcoding marker; however, in some animal species it is hypervariable and therefore difficult to sequence with traditional methods. with next-generation sequencing (ngs) it is possible to sequence all gene variants despite the presence of single nucleotide polymorphisms (snps), insertions/deletions (indels), homopolymeric regions, and microsatellites. our aim was to compare the performance of sanger sequencing and ngs amplicon sequencing in c ... | 2017 | 27799340 |
| mosquito-borne heartworm dirofilaria immitis in dogs from australia. | heartworm (dirofilaria immitis) in dogs is considered endemic in australia, but the clinical heartworm disease caused by the heartworm is rare and prevalence is low. the mainstream prevention of the heartworm is based on macrocyclic lactone (ml) administration. the aim of this study was to confirm endemism of the heartworm under current australian conditions using a cohort of recent microfilaria-positive dogs which were on variable heartworm prevention. | 2016 | 27717406 |
| assessment of local mosquito species incriminates aedes aegypti as the potential vector of zika virus in australia. | within the last 10 years zika virus (zikv) has caused unprecedented epidemics of human disease in the nations and territories of the western pacific and south america, and continues to escalate in both endemic and non-endemic regions. we evaluated the vector competence of australian mosquitoes for zikv to assess their potential role in virus transmission. | 2016 | 27643685 |
| mosquito communities and disease risk influenced by land use change and seasonality in the australian tropics. | anthropogenic land use changes have contributed considerably to the rise of emerging and re-emerging mosquito-borne diseases. these diseases appear to be increasing as a result of the novel juxtapositions of habitats and species that can result in new interchanges of vectors, diseases and hosts. we studied whether the mosquito community structure varied between habitats and seasons and whether known disease vectors displayed habitat preferences in tropical australia. | 2016 | 27388293 |
| comparative mt genomics of the tipuloidea (diptera: nematocera: tipulomorpha) and its implications for the phylogeny of the tipulomorpha. | a traditionally controversial taxon, the tipulomorpha has been frequently discussed with respect to both its familial composition and relationships with other nematocera. the interpretation of internal relationships within the tipuloidea, which include the tipulidae sensu stricto, cylindrotomidae, pediciidae and limoniidae, is also problematic. we sequenced the first complete mitochondrial (mt) genome of symplecta hybrida (meigen, 1804), which belongs to the subfamily chioneinae of family limoni ... | 2016 | 27341029 |
| desiccation survival time for eggs of a widespread and invasive australian mosquito species, aedes (finlaya) notoscriptus (skuse). | the australian native mosquito aedes (finlaya) notoscriptus (skuse) is closely associated with natural and artificial water holding receptacles. eggs are laid in habitats where they are exposed to drying conditions as water levels fluctuate. withstanding desiccation enables survival in challenging environments and increases the potential for establishment in non-native habitats. until now, the desiccation resistance of ae. notoscriptus eggs has been unknown despite the historical invasive succes ... | 2016 | 27232125 |
| molecular identification of mosquitoes (diptera: culicidae) in southeastern australia. | dna barcoding is a modern species identification technique that can be used to distinguish morphologically similar species, and is particularly useful when using small amounts of starting material from partial specimens or from immature stages. in order to use dna barcoding in a surveillance program, a database containing mosquito barcode sequences is required. this study obtained cytochrome oxidase i (coi) sequences for 113 morphologically identified specimens, representing 29 species, six trib ... | 2016 | 27217948 |
| highly divergent dengue virus type 1 genotype sets a new distance record. | dengue viruses (denvs) are the leading cause of mosquito-borne viral disease of humans. they exist in both endemic and sylvatic ecotypes. in 2014, a viremic patient who had recently visited the rainforests of brunei returned to australia displaying symptoms consistent with denv infection. a unique denv strain was subsequently isolated from the patient, which we propose belongs to a new genotype within denv serotype 1 (denv-1). bayesian evolutionary phylogenetic analysis suggests that the putativ ... | 2016 | 26924208 |
| differentiation of aedes aegypti and aedes notoscriptus (diptera: culicidae) eggs using scanning electron microscopy. | aedes notoscriptus and aedes aegypti are both peri-domestic, invasive container-breeding mosquitoes. while the two potential arboviral vectors are bionomically similar, their sympatric distribution in australia is limited. in this study, analyses of ae. aegypti and ae. notoscriptus eggs were enabled using scanning electron microscopy. significant variations in egg length to width ratio and outer chorionic cell field morphology between ae. aegypti and ae. notoscriptus enabled distinction of the t ... | 2016 | 26845557 |
| a native wolbachia endosymbiont does not limit dengue virus infection in the mosquito aedes notoscriptus (diptera: culicidae). | the endosymbiotic bacterium wolbachia pipientis infects many species of insects and has been transinfected into the mosquito aedes aegypti (l.), the primary vector of dengue virus (denv). recently, it has been shown that wolbachia blocks the replication and transmission of rna viruses, such as denv, in a number of mosquito species including ae. aegypti and aedes albopictus (skuse), which is naturally infected with wolbachia and considered a secondary vector for denv. the mosquito species aedes n ... | 2016 | 26721865 |
| 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 |
| risky behaviors: effects of toxorhynchites splendens (diptera: culicidae) predator on the behavior of three mosquito species. | viable biocontrol agents for mosquito control are quite rare, therefore improving the efficacy of existing biological agents is an important study. we need to have a better understanding of the predation-risk behavioral responses toward prey. this research examined prey choices by toxorhynchites splendens by monitoring the behavioral responses of aedes aegypti, aedes albopictus, and anopheles sinensis larvae when exposed to the predator. the results show that tx. splendens prefers to consume ae. ... | 2015 | 26386041 |
