Since May 2015, severe outbreaks of hepatitis-hydropericardium syndrome (HHS) associated with infections fowl aviadenovirus (FAdV) have emerged in broiler chickens several Chinese provinces. To identify the genotype and gain a better understanding genetic properties FAdV strains responsible for recent HHS China, complete genome sequences five isolates from provinces were determined. The results demonstrated that novel 4 (FAdV-4) was epidemic China. investigate molecular characteristics these...

Pseudorabies (PR) is a significant disease that adversely affects the healthy growth of pig industry in China. However, data on molecular epidemiology and genetic characterization PRV sparse. This study examined epidemic trends variation characteristics PR virus (PRV) Henan Province Six hundred eighty-eight clinically infected tissue samples were collected from 18 cities January 2021 to March 2023 tested for PRV. The was isolated positive identified by polymerase chain reaction...

Interferon-stimulated gene 15 (ISG15) is strongly upregulated during viral infections and exerts pro-viral or antiviral actions. While many viruses combat host defenses by limiting ISG expression, PRV infection notably increases expression of ISG15. However, studies on the strategies to regulate ISG15-mediated responses are limited. Here, we demonstrate that PRV-induced free ISG15 conjugated proteins accumulation require expression. Conjugation inhibition assays showed imposes its effects...

Abstract Background Streptococcus agalactiae or group B (GBS) is a leading infectious cause of neonatal morbidity and mortality. It essential to establish robust method for the rapid ultra-sensitive detection GBS in pregnant women with premature rupture membrane (PROM). Methods This study developed CRISPR-GBS assay that combined advantages recombinase polymerase amplification (RPA) CRISPR/Cas12a system detection. The clinical performance was assessed using vaginal cervical swabs were...

Re-emerging pseudorabies (PR) caused by virus (PRV) variant has been prevailing among immunized herds in China since 2011, indicating that commercially available PR vaccine strains couldn't provide complete protection against novel, epidemic PRV variant. Before this study, a gE/TK-gene-deleted (PRV ΔgE/TK) was constructed from QYY2012 through homologous recombination and Cre/LoxP system. Here, ΔgE/TK/US3 strain generated deleting US3 gene based on ΔgE/TK using the same method. The growth...

Chicken infectious anemia (CIA) is an immunosuppressive disease caused by the chicken virus (CIAV) resulting in heavy economic losses once outbreak established. This study conducted a systematic analysis of epidemiology and pathology CIA Henan province, China. A total 437 clinical tissue samples 120 poultry disease-related live attenuated vaccines were collected during 2017-2020; which 45 positive for CIAV nucleic acid, with rate 8.08%. Our results showed that genome sequence similarity...

Hepatitis E virus (HEV) is a small nonenveloped single‐stranded positive‐sense RNA and one of the major causes for acute hepatitis worldwide. CXCL‐8 multifunctional proinflammatory chemokine. It was reported recently that HEV infection significantly upregulates gene expression. In this study, we investigated mechanism HEV‐induced transcriptional activation. Using promoter reporters different lengths ranging from −1400 to −173, showed −173 has highest activity in presence genomic RNA,...

Viral-encoded microRNAs (miRNAs) have vital roles in the regulation of virus replications and host immune responses. The results previous studies indicated that miRNA clusters are involved replication virulence pseudorabies (PRV), which may potentially lead to escape or facilitation PRV replication. This study's research revealed prv-miR-LLT11a was differentially expressed during infection. present demonstrated could significantly inhibit It further determined SLA-1 target gene...

Pseudorabies virus (PRV) can establish lifelong latent infection in peripheral nervous ganglion, and persistent infections blood lymphocytes. Establishing an the lymphocytes does not only enable PRV to escape host immune surveillance but pass through placental barrier, leading fetal death abortion. Due pathogenicity of PRV, it poses a huge challenge its prevention control. The escapes immunity downregulation swine leukocyte antigen class I (SLA I) molecules on infected cells. However, data...

Introduction: In the past two decades, there has been 84% increase of stroke prevalence in China. Since transitional care facilities are lacking China, most survivors return home after discharged from acute hospital setting. Routine disease-oriented discharge planning does not match individual needs. Objective: To evaluate effectiveness a modified (HC) intervention to facilitate transition for home. Methods: Using quasi-experimental study design, 115-bed unit teaching China were recruited....
