Genome sequencing and transcriptome analysis of Geotrichum citri-aurantii on citrus reveal the potential pathogenic- and guazatine-resistance related genes.

Sour rot, caused by Geotrichum citri-aurantii, is a major postharvest disease of citrus，and it causes serious economic losses. In this study, a high-quality genome sequence of G. citri-aurantii was obtained by Single Molecule Real-Time Sequencing (SMRT).

Emergence of genotype I of Japanese encephalitis virus as the dominant genotype in Asia.

Japanese encephalitis virus (JEV), a mosquito-borne zoonotic pathogen, is one of the major causes of viral encephalitis worldwide. Previous phylogenetic studies based on the envelope protein indicated that there are four genotypes, and surveillance data suggest that genotype I is gradually replacing genotype III as the dominant strain. Here we report an evolutionary analysis based on 98 full-length genome sequences of JEV, including 67 new samples isolated from humans, pigs, mosquitoes, midges.

[Biological and phylogenetic analysis of first isolate of Tahyna virus in China].

In 2006, the first Chinese Tahyna virus isolate (XJ0625) was obtained in Xinjiang province and human infection were found in the same region. In this study, cell culture, animal experiments, electron microscopy, immunofluorescence assay and cross neutralization tests were performed to see the cell susceptibility, animal pathogenicity, morphology and antigenic and other biological characteristics of XJ0625. In addition, molecular biology software was used to analyze the characteristics of molecular evolution.

[Isolation and primary identification of viruses in mosquitoes in the south of Xinjiang].

Objective: To isolate viruses from mosquitoes in the south of Xinjiang and identify these viruses primarily.

Methods: A total of 13 491 mosquitoes were collected in the south of Xinjiang from Jul to Aug, 2005. These mosquitoes were divided into 130 groups and grinded respectively.

[A new member of Brevidensovirus, 0507JS11 virus isolated from Culex mosquitoes collected in Xinjiang].

Objective: To probe the primary characteristic of 0507JS11 virus isolated from Culex sp. and determine the classification of 0507JS11 virus in taxonomy.

Methods: 0507JS11 virus was cultured in Aedes albopictus C6/36 cells and cytopathic effects (CPEs) were recorded.

Tahyna virus and human infection, China.

In 2006, Tahyna virus was isolated from Culex spp. mosquitoes collected in Xinjiang, People's Republic of China. In 2007, to determine whether this virus was infecting humans, we tested serum from febrile patients.
