Transcriptomic analysis of chicken immune response to infection of different doses of Newcastle disease vaccine.

Newcastle disease virus (NDV) is a contagious poultry paramyxovirus, leading to substantial economic losses to the poultry industry. Here, RNA-seq was carried out to investigate the altered expression of immune-related genes in chicken thymus within 96 h in response to NDV infection. In NDV-infected chicken thymus tissues, comparative transcriptome analysis revealed 1386 differentially expressed genes (DEGs) at 24 h with 989 up- and 397 down-regulated genes, 728 DEGs at 48 h with 567 up- and 161 down-regulated genes, 1514 DEGs at 72 h with 1016 up- and 498 down-regulated genes, and 1196 DEGs at 96 h with 522 up- and 674 down-regulated genes, respectively.

A new species of freshwater crab of the genus Türkay & Dai, 1997 (Crustacea, Decapoda, Brachyura, Potamidae) from Guizhou, China.

A new species of Türkay & Dai, 1997 from a karst system in southwest China is described. The new species can be separated from congeners by the combination of a sharp and distinct epibranchial tooth, the anterolateral region lined with few scattered granules, the terminal segment of the male first gonopod distinctly bent with a constant diameter, and the position of the female vulvae. Mitochondrial 16S rDNA genetic data was used to investigate the systematic position of the new species, which is supported as a new taxon.

The complete mitochondrial genome of the freshwater crab (Decapoda: Brachyura: Potamoidea).

We report the complete mitochondrial genome of for the first time, which is found to be 16,547 base pairs in length, and contains 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA), and one non-coding AT-rich region known as the D-loop. In addition, the mitogenome has 17 intergenic regions ranging from 1 to 1512 bp in length. The mitochondrial genome of is the first mitochondrial genome under the genus , providing DNA data for species identification, enriching the species diversity of Brachyura, and providing a basis for further studies on population genetics and phylogenetics.

A new species of karst-dwelling freshwater crab of the genus Dai & Naiyanetr, 1994 (Crustacea: Decapoda: Brachyura: Potamidae), from Guizhou, southwest China.

sp. n. from Maolan National Nature Reserve, Guizhou, southwest China, is described.

The complete mitochondrial genome of Somanniathelphusa boyangensis and phylogenetic analysis of Genus Somanniathelphusa (Crustacea: Decapoda: Parathelphusidae).

In this study, the authors first obtained the mitochondrial genome of Somanniathelphusa boyangensis. The results showed that the mitochondrial genome is 17,032bp in length, included 13 protein-coding genes, 2 rRNAs genes, 22 tRNAs genes and 1 putative control region, and it has the characteristics of the metazoan mitochondrial genome A+T bias. All tRNA genes display the typical clover-leaf secondary structure except tRNASer(AGN), which has lost the dihydroxyuridine arm.

[Risk factors of infection in Xingzi County].

Objective: To explore the risk factors of infection in the residents in Xingzi County, Jiangxi Province.

Methods: Six administrative villages from different areas were randomly selected by the cluster sampling method as the study sites in Xingzi Country in 2013, and all the residents aged 5 years or above were investigated epidemiologically, and the schistosome infection was surveyed by Kato-Katz technique. The risk factors of schistosomiasis were analyzed by using the Chi-square test analysis and multivariate Logistic regression model.

[A review of researches on Angiostrongylus cantonensis and angiostrongyliasis cantonensis: analysis of related literatures].

Angiostrongylus cantonensis is a lung worm of rat (definitive host). Human, an abnormal host, can acquire the infection by ingesting food containing the infective larvae of this worm (third-stage larvae). Although the larvae cannot develop into adult worm in human body, it moves to human brain and eyes, causing eosinophilic meningitis (EM), meningoencephalitis, or ocular angiostrongyliasis (OA).

[Survival and reproduction of Oncomelania hupensis robertsoni in water network regions in Hubei Province, China].

Objective: To understand the possibility of the survival and reproduction of Oncomelania hupensis robertsoni snails in water network regions in Hubei Province, as well as their expected lifespan after leaving the original propagating environment, so as to provide the basic data and precondition for reducing the infection rates of O. h. hupensis in the lake regions.

[Gastroscopic and pathological characteristics of patients with or without schistosomiasis in Poyang Lake area].

Objectives: To understand the gastroscopic and pathological characteristics of patients with miasis in Poyang Lake area, and to explore the relationship between schistosomiasis and pathological changes of gastric mucosa.

Methods: Volunteers with or without schistosomiasis were recruited and divided into a case group and a control group. All the objects were examined by electronic gastroscopy and pathological examinations.

Recent vicariant and dispersal events affecting the phylogeny and biogeography of East Asian freshwater crab genus Nanhaipotamon (Decapoda: Potamidae).

The molecular phylogeny and biogeography of the East Asian freshwater crabs of the genus Nanhaipotamon (Decapoda: Brachyura: Potamidae) were studied, using two mitochondrial (16S rRNA and cytochrome oxidase I) and one nuclear (28S rRNA) markers, and correlated with various vicariant and dispersal events which have occurred in this region. The results showed Nanhaipotamon to be a monophyletic taxon with four clades which correspond to the topography of the coastal region of southeastern China and Taiwan Island. Mountains appear to play an important role in the distribution.

[Epidemiological survey on the infection of Paragonimus westermani in Jiangxi Province].

Objective: To investigate Paragonimus westermani infection in the intermediate hosts and animal reservoivs in Jiangxi Province.

Methods: Two forest farms in Jingan and Wanzai Counties and one town in Yushan County of Jiangxi Province were selected as pilots for epidemiological and retrospective survey. The intermediate hosts (snails, crabs) and reservoir hosts (cat, dog, civet cat, wildcat, etc.

[The second stage larvae of Ascaris lumbricoides].

Objective: To induce the apoptosis of human alveolar epithelial cells (A549) by the extraction of the second stage larvae of Ascaris lumbricoides and investigate the extraction concentration and inducing time related to the apoptosis.

Methods: Following to the results of Microculture Tetrazolium Test (MTT), five concentrations of the extraction of the second stage larvae were chosen to induce the apoptosis of A549 cells. Meanwhile, control groups without the inducement were set up.
