During summers in 2007 and 2008, an investigation was conducted to identify the distribution of mosquitoes and circulation of mosquito-borne arboviruses in Inner Mongolia, China. A total of 10,542 mosquitoes consisting of seven species from the Aedes, Culex, and Anopheles genera were trapped by UV-light traps, and they were sorted into 211 pools according to species, location, and date of collection. The result showed that Aedes dorsalis was the most common species, accounting for 41.0% (4327/10,542) of the total. Culex modestus (17.1%, 1801/10,542) made up the second largest species, followed by Aedes flavidorsalis (16.3%, 1714/10,542). Six virus isolates were obtained from pooled mosquitoes using cell culture and were identified as Tahyna virus (two isolates from Ae. dorsalis and C. modestus), Banna virus (one isolate from C. modestus), and Culex Pipiens pallens Densovirus (three isolates from Aedes caspius) by serological and molecular methods.

“…Since then, BAV has been isolated from various mosquito specimens (Liu et al, 2010), suggesting that mosquitoes are the natural vector for BAV. To date, BAV has been isolated from mosquito specimens collected in Indonesia (Brown et al, 1993), Vietnam (Nabeshima et al, 2008), South Korea (Kim et al, 2016), as well as from many subtropical or temperate provinces of China (Gansu, Shanxi, Inner Mongolia, Liaoning, Beijing, and Yunnan) (Liu et al, 2010a;Liu et al, 2010b;Liu et al, 2011). Moreover, it was recently reported that BAV has been isolated in Hungary, which is in the northern, more temperate zone of Europe (Reuter et al, 2013).…”

In an investigation of blood-sucking insects and arboviruses, a virus (YN12243) was isolated from Culicoides samples collected in the Sino-Burmese border region of Yunnan Province, China. The virus caused cytopathic effect (CPE) in C6/36 cells and passaged stably. Polyacrylamide gel analysis showed that the genome of YN12243 was composed of 12 segments of double-stranded RNA (dsRNA), with a distribution pattern of 6-6. The nucleotide and amino acid sequences of the coding region (1‒12 segments) were 17,803 bp and 5,925 amino acids in length, respectively. The phylogenetic analysis of VP1 protein (RdRp) revealed that YN12243 belonged to genus Seadornavirus of family Reoviridae, and further analysis indicated that YN12243 belongs to the Banna virus (BAV) genotype A2. Additionally, YN12243 was located in the same evolutionary cluster as BAV strains isolated from different mosquito species, suggesting that the BAV isolated from Culicoides does not have species barriers. These results indicate that Culicoides can also be a vector for BAV. In view of the hematophagous habits of Culicoides on cattle, horses, deer, and other large animals, as well as the possibility of spreading and causing a variety of animal arboviral diseases, it is important to improve infection detection and monitor the BAV in large livestock.

“…There are three species of seadornaviruses: Banna virus (BAV), Kadiporo virus (KDV) and LNV. BAV has been isolated from encephalitic humans (26, 27), pigs, cattle (28), and mosquitoes in China (29, 30), Indonesia (31) and Vietnam (32). Serosurveys of patients with encephalitis across China revealed a BAV seroprevalence of about 10% (33).…”

Enhanced arbovirus surveillance with deep sequencing: Identification of novel rhabdoviruses and bunyaviruses in Australian mosquitoes

et al. 2014

View full text Add to dashboard Cite

Viral metagenomics characterizes known and identifies unknown viruses based on sequence similarities to any previously sequenced viral genomes. A metagenomics approach was used to identify virus sequences in Australian mosquitoes causing cytopathic effects in inoculated mammalian cell cultures. Sequence comparisons revealed strains of Liao Ning virus (Reovirus, Seadornavirus), previously detected only in China, livestock-infecting Stretch Lagoon virus (Reovirus, Orbivirus), two novel dimarhabdoviruses, named Beaumont and North Creek viruses, and two novel orthobunyaviruses, named Murrumbidgee and Salt Ash viruses. The novel virus proteomes diverged by ≥50% relative to their closest previously genetically characterized viral relatives. Deep sequencing also generated genomes of Warrego and Wallal viruses, orbiviruses linked to kangaroo blindness, whose genomes had not been fully characterized. This study highlights viral metagenomics in concert with traditional arbovirus surveillance to characterize known and new arboviruses in field-collected mosquitoes. Follow-up epidemiological studies are required to determine whether the novel viruses infect humans.
