Rickettsia heilongjiangensis, a tick-borne obligate intracellular bacterium and causative agent of spotted fever in China, has attracted increasing concern regarding its capability in causing human rickettsiosis. Here, we conducted a genomic analysis of a new Rickettsia heilongjiangensis strain B8 (B8) isolated from the serum of a patient who had been bitten by a Haemaphysalis longicornis tick in Anhui Province, China. The present study sought to identify exclusive genes that might be associated with the pathogenicity...

Genetic, biological and epidemiological study on a cluster of H9N2 avian influenza virus infections among chickens, a pet cat, and humans at a backyard farm in Guangxi, China

During an investigation in October 2018, two people with diarrhoea, mild abdominal pain, and mild arthralgia symptoms in Guangxi, China, were identified as infected by H9N2 avian influenza virus (AIV). Four H9N2 AIVs were isolated from one of two patients, a pet cat, and a dead chicken (two respective isolates from its lung and kidney tissues) bred by the patients at a backyard farm. Epidemiological investigation indicated that the newly bought chicken died first, and...

Induction of Significant Neutralizing Antibodies against SARS-CoV-2 by a Highly Attenuated Pangolin Coronavirus Variant with a 104nt Deletion at the 3'-UTR

SARS-CoV-2 related coronaviruses (SARS-CoV-2r) from Guangdong and Guangxi pangolins have been implicated in the emergence of SARS-CoV-2 and future pandemics. We previously reported the culture of a SARS-CoV-2r GX_P2V from Guangxi pangolins. Here we report the GX_P2V isolate rapidly adapted to Vero cells by acquiring two genomic mutations: an alanine to valine substitution in the nucleoprotein and a 104-nucleotide deletion in the hypervariable region (HVR) of the 3′-terminus untranslated region (3′-UTR). We further report the...

Profile of clinical characteristics and serologic markers of sporadic hepatitis E in a community cohort study

Zi-Min Tang, Gui-Ping Wen, Dong Ying, Si-Ling Wang, Chang Liu, Wei-Kun Tian, Ying-Bin Wang, Mu-Jin Fang, Yu-Lin Zhou, Yun-Sheng Ge, Ting Wu, Jun Zhang, Shou-Jie Huang, Zi-Zheng Zheng & Ning-Shao Xia
Hepatitis E virus (HEV) is a pathogen of global significance, but the value of HEV-related markers in the diagnosis of hepatitis E remains controversial. Previous studies on hepatitis E profiles have been mainly cross-sectional and conducted among inpatients in large hospitals, and hepatitis E cases have been primarily defined by limited partial markers. In this community-based study, 4,110 active hepatitis cases from a population of nearly 600,000 were followed over 48 months and serial serum...

Identification of key candidate genes for wing length-related traits by whole-genome resequencing in 772 geese

1. A total of 772, 420-day-old Xingguo gray geese (XGG) were sequenced using a low-depth (~1×) whole-genome resequencing strategy to reveal the genetic mechanism of wing length-related traits by genome-wide association analysis (GWAS). 2. The results showed that 119 SNPs had genome-wide significance for wing length in five regions of chromosome 4, of which the most significant locus (P=7.95E-11) was located upstream of RBM47 and explained 7.3% of phenotypic variation. 3. A total of 219...

Comparison of ozone-based AOPs on the removal of organic matter from the secondary biochemical effluent of coking wastewater

Yuxian Ji, Chunrong Wang, Lei He, Xiaoya Chen, Jianbing Wang, Xian Zhang & Qingbang Du
Advanced oxidation processes (AOPs) based on ozone are gaining continuously growing popularity in wastewater treatment. This study explored the treatment of coking wastewater using a combination of ozonation (O3), ultraviolet (UV), and hydrogen peroxide (H2O2) process expressed by % chemical oxygen demand (COD) removal, % total organic carbon (TOC), % UV254, % fluorescence intensity removal and its electrical energy consumption. The obtained results demonstrated that, the combination of O3, UV, and H2O2 which is denoted...

Molecular detection and identification of relapsing fever Borrelia in ticks and wild small mammals in China

Xiao-Ai Zhang, Feng Tian, Yue Li, Xiao-Long Zhang, Bao-Gui Jiang, Bao-Cheng Liu, Jing-Tao Zhang, Shen Tian, Heng Ding, Shuang Li, Hao Li, Li-Qun Fang & Wei Liu
We identified relapsing fever (RF) Borrelia in 1.45% (145/10426) of the ticks and 1.40% (40/2850) of the wild mammals in a field investigation in China. Three RF Borrelia species, including human-pathogenic Borrelia miyamotoi, Borrelia persica and unclassified Babesia sp. were determined. Main species determined from ticks was B. miyamotoi (44.14%), followed by the unclassified Borrelia sp. (42.76%), and Borrelia theileri (13.10%). In wild mammals, main species found was B. persica (57.50%), followed by the unclassified...

Mapping active paddy rice area over monsoon Asia using time-series Sentinel – 2 images in Google Earth Engine; A case study over Lower Gangetic Plain

Arabinda Maiti, Prasenjit Acharya, Srikanta Sannigrahi, Qi Zhang, Somnath Bar, Suman Chakraborti, Bijoy K Gayen, Gunadhar Barik, Surajit Ghosh & Milap Punia
We proposed a modification of the existing approach for mapping active paddy rice fields in monsoon-dominated areas. In the existing PPPM approach, LSWI higher than EVI at the transplantation stage enables the identification of rice fields. However, it fails to recognize the fields submerged later due to monsoon floods. In the proposed approach (IPPPM), the submerged fields, at the maximum greenness time, were excluded for better estimation. Sentinel–2A/2B time-series images were used for the year...
