Molecular characterization of porcine epidemic diarrhea virus associated with outbreaks in southwest China during 2014-2018.

Porcine epidemic diarrhea virus (PEDV), which re-emerged in China since 2010, has swept across the whole country leading to tremendous economic losses. In this study, a total of 645 diarrhea samples collected from 156 pig farms in Sichuan and Guizhou province during 2014-2018 were tested for PEDV. We found that samples from 47.

Complete genome sequence and pathogenicity of fowl adenovirus serotype 4 involved in hydropericardium syndrome in Southwest China.

Since 2015, an emerging infectious disease of inclusion body hepatitis and hydropericardium syndrome (IBH-HPS) has been occurred in China, which caused economic loss in poultry farming. In this study, we isolated four fowl adenovirus strains from flocks with an outbreak of HPS. The complete nucleotide sequence of SC-Neijiang was determined and its pathogenicity was evaluated.

Infectious Bronchitis Virus Infection Induces Apoptosis during Replication in Chicken Macrophage HD11 Cells.

Avian infectious bronchitis has caused huge economic losses in the poultry industry. Previous studies have reported that infectious bronchitis virus (IBV) infection can produce cytopathic effects (CPE) and apoptosis in some mammalian cells and primary cells. However, there is little research on IBV-induced immune cell apoptosis.

Various Sequence Types of Escherichia coli Isolates Coharboring and Genes from a Commercial Swine Farm in China.

Sixteen different sequence types (STs) of isolates from a commercial swine farm in China were confirmed to coharbor the carbapenem resistance gene and the colistin resistance gene Whole-genome sequencing revealed that and were located on a 46-kb IncX3 plasmid and a 32-kb IncX4 plasmid, respectively. The two plasmids can transfer together with a low fitness cost, which might explain the presence of various STs of coharboring and .

Percutaneous transluminal septal myocardial ablation for hypertrophic obstructive cardiomyopathy; The Chinese experience in 119 patients from a single center.

Background: Percutaneous transluminal septal myocardial ablation (PTSMA) has been introduced as an alternative treatment for hypertrophic obstructive cardiomyopathy (HOCM). We report on the acute, short- and long-term results of our experiences in 119 patients from a single center in China.

Methods And Results: PTSMA was performed in 119 patients with symptomatic HOCM (mean age 35.

Experimental study of relationship between intracoronary alcohol injection and the size of resultant myocardial infarct.

Background: Hypertrophic obstructive cardiomyopathy (HOCM) is a complex disease with unique pathophysiologic characteristics and a great diversity of morphologic,functional and clinical features. Percutaneous transluminal septal myocardial ablation (PTSMA) using alcohol injection via a catheter into the septal branch of the left anterior descending coronary artery has been recently introduced as a promising nonsurgical therapy for HOCM. However, the relationship between the volume and velocity of intracoronary injection of absolute alcohol and the size of the resultant myocardial infarct has not been investigated.
