Characterization of an H7N9 Influenza Virus Isolated from Camels in Inner Mongolia, China.

The H7N9 subtype of influenza virus can infect birds and humans, causing great losses in the poultry industry and threatening public health worldwide. However, H7N9 infection in other mammals has not been reported yet. In the present study, one H7N9 subtype influenza virus, A/camel/Inner Mongolia/XL/2020 (XL), was isolated from the nasal swabs of camels in Inner Mongolia, China, in 2020.

[Schistosomiasis surveillance among migrant population in Haining City in 2015].

Objective: To understand the schistosomiasis epidemic situation among migrant population, so as to assess the potential risk of schistosomiasis transmission in Haining City.

Methods: Five districts in Haining City were randomly selected to investigate the schistosomiasis endemic situation in migrant population from the schistosomiasis endemic provinces.

Results: Totally 1 207 persons were investigated and four positives were found in serological tests, with the positive rate of 0.

[Endemic situation of schistosomiasis in a surveillance site of river and lake regions in Haining City, 2012-2014].

Objective: To understand the endemic dynamics and situation of schistosomiasis in a provincial surveillance site in Haining City, Zhejiang Province.

Methods: The snail status, schistosome infection situations of permanent residents and floating population in Qinmin Village, Haining City were monitored from 2012 to 2014 according to .

Results: Totally 600 permanent residents were examined from 2012 to 2014.

Selection of scFvs specific for the HepG2 cell line using ribosome display.

The aim of this study was to construct a ribosome display library of single chain variable fragments (scFvs) associated with hepatocarcinoma and screen such a library for hepatocarcinoma-binding scFvs. mRNA was isolated from the spleens of mice immunized with hepatocellular carcinoma cell line HepG2. Heavy and k chain genes (VH and k) were amplified separately by RT-PCR, and an anti-HepG2 VH/k chain ribosome display library was constructed by assembling VH and k into the VH/k chain with a specially constructed linker by SOE-PCR.
