[Community structure and distribution pattern of small mammals in agricultural area of Yunnan Province, China.].

To understand the characteristics of community structure and spatial distribution of small mammals in agricultural area of Yunnan Province, a systematic investigation was carried out in 104 quadrats of 25 regions in Yunnan Province from August 2010 to April 2018 by rat trap night method. The spatial variation of community characteristics along environmental gradients was analyzed by community ecological indicators. The results showed that a total of 3240 small mammals were captured and cold be classified into 42 species in 21 genera, 9 families, and 4 orders.

A new hantavirus from the stripe-backed shrew (Sorex cylindricauda) in the People's Republic of China.

Inspired by the recent discovery of genetically distinct hantaviruses from insectivore species worldwide, we performed a small-scale search for insectivore-borne hantaviruses. In this paper, we report the discovery of a new hantavirus, which was designated the Qian Hu Shan virus (QHSV). This virus was detected in the lung tissues of three stripe-backed shrews (Sorex cylindricauda), which were captured in the Yunnan Province, China.

[Ecological-geographic landscapes of natural plague foci in China VII. Typing of natural plague foci].

Objective: To group and characterize natural plague foci in China.

Methods: A novel two-class typing method as well as a three-indication nomenclature method were established to group and characterize the natural plague foci, on the basis of eco-geographical landscapes of plague foci, genetics of Yersinia pestis, zoology of rodent reservoirs and the entomology of flea vectors.

Results: A total of 12 distinct natural plague foci (including 19 subtypes) as well as their biological features were characterized.

[Ecological-geographic landscapes of natural plague foci in China VI. Biological characteristics of natural vectors of Yesinia pestis].

Objective: To characterize the biological characteristics of natural vectors of Yersinia (Y.) pestis in China.

Methods: Species and genera of natural vectors of Y.

Genetic analysis of a hantavirus strain carried by Niviventer confucianus in Yunnan province, China.

Hantavirus genome sequences were recovered from lung tissues of Chinese white-bellied rats (Niviventer confucianus) captured in Yunnan province, China. Pairwise comparison of the nucleotide and deduced amino acid sequences of the entire S and partial M and L segments indicated that the newly discovered virus strain, which was designated as strain YN509, was very different from other rodent-borne hantaviruses. Phylogenetic analysis showed that the new strain fit into a clade containing Da Bie Shan virus (DBSV) (also carried by N.

[Fleas on small mammals in the surrounding area of Erhai Lake].

Objective: To investigate the distribution pattern, species diversity and community structure of fleas on small mammals in the surrounding area of Erhai Lake, and the relationship between fleas and their hosts.

Methods: Different geographical areas surrounding the Erhai Lake in Yunnan were selected as investigated spots. Small mammals were captured with baited cages.

[Identification of Anaplasma phagocytophilum in small mammals from Hengduan Mountains of Southwest China].

Objective: To investigate the prevalence of Anaplasma phagocytophilum in small mammals from the forest area of Hengduan Mountains in southwestern China.

Methods: Small mammals captured from Gaoligong and Xianggelila mountainous area of Yunnan province were detected by PCR amplification. The sequences of 16S rRNA and Msp4 gene fragments from positive samples were compared with corresponding sequences deposited in GenBank.

Isolation and characterization of the full coding sequence of a novel densovirus from the mosquito Culex pipiens pallens.

During an investigation of arboviruses in China, a novel densovirus (DNV) was isolated from the adult female Culex pipiens pallens. The virus, designated Culex pipiens pallens densovirus (CppDNV), caused cytopathic effect in C6/36 cells. The virus particles were icosahedral, non-enveloped and had a mean diameter of 24 nm.

[Study on the prevalence of Bartonella species in rodent hosts from different environmental areas in Yunnan].

Objective: To investigate Bartonella infections in small mammalian reservoir hosts from different environments and types of climate in Yunnan.

Methods: Femoral blood samples were collected from the anesthetic captured animals from five counties including three types of climate. All isolates were grown on brain and heart infusion agar plates containing 5% defibrinated rabbit blood.
