AI Article Synopsis
- Human herpesviruses can cause serious illnesses, particularly affecting the central nervous system, highlighting the need for better diagnostic tools.
- A new microarray-based method was developed to detect eight types of human herpesviruses in various clinical specimens like cerebrospinal fluid and blood.
- The study tested 227 specimens and achieved a 94% concordance rate with traditional PCR methods, showing that the microarray technique can effectively identify multiple herpesvirus infections in clinical samples.
Article Abstract
Background: Human herpesviruses cause clinically important diseases, e.g. infections of the central nervous system. New diagnostic tools are required for rapid and reliable detection of these viruses.
Objectives: A microarray-based method was designed for detection of eight human herpesviruses in cerebrospinal fluid (CSF), whole blood, plasma, serum and proficiency-testing specimens.
Study Design: Herpes simplex type 1 and 2, varicella-zoster, cytomegalo-, Epstein-Barr and human herpes viruses 6A, 6B and 7 were amplified from clinical specimens by two multiplex-PCRs and transcribed to single-stranded RNAs which were hybridized to oligonucleotides on microarray. The results were compared to those from conventional PCR. In total, 227 specimens were tested including 23 CSF, 10 whole blood, 73 plasma, 10 proficiency-testing samples and 111 negative control samples.
Results: Concordant results were obtained in 214/227 (94%). Microarray detected 10 possible double and one triple infection. Negative control samples (70 serum, 30 CSF and 11 proficiency-testing samples) were all negative.
Conclusions: Microarray is suitable for detection of multiple herpesviruses in clinical samples.

Pseudorabies virus (PRV) is one of the most important infectious diseases which leads to significant economic losses in the global swine industry. The gE-deleted vaccine is widely used to prevent susceptible pigs from PRV infection. There is no report of the differentiation of PRV wild strain and vaccine strain by recombinase polymerase amplification (RPA) coupled with a lateral flow dipstick (LFD) method.

BACKGROUND This study aimed to analyze the risk factors of central nervous system (CNS) infection caused by reactivation of varicella zoster virus (VZV) and provide reference for the prevention and early diagnosis of VZV-associated CNS infection. MATERIAL AND METHODS A prospective study was conducted on 1030 patients with acute herpes zoster (HZ) admitted to our hospital from January 2021 to June 2023. According to clinical manifestations and auxiliary examinations, they were divided into HZ group of 990 patients and VZV-associated CNS infection group of 40 patients.

Background: Canine adipose-derived mesenchymal stem cells (cAD-MSCs) demonstrate promising tissue repair and regeneration capabilities. However, the procurement and preservation of these cells or their secreted factors for therapeutic applications pose a risk of viral contamination, and the consequences for cAD-MSCs remain unexplored. Consequently, this research sought to assess the impact of canid alphaherpesvirus 1 (CHV) on the functional attributes of cAD-MSCs, including gene expression profiles and secretome composition.

Live herpesvirus-vectored vaccines are critical in veterinary medicine, but they can sometimes offer insufficient protection due to suboptimal antigen expression or localization. Encephalomyocarditis virus (EMCV) is a significant zoonotic threat, with VP1 protein as a key immunogen on its capsid. To enhance immunogenicity, we explored the use of recombinant pseudorabies virus (rPRV) as a vaccine vector against EMCV.

Objective: Acute retinal necrosis (ARN) caused by varicella-zoster virus (VZV) is associated with changes in specific proteins in the eye's fluid, particularly matrix metalloproteinase-3 (MMP-3), an enzyme that breaks down tissue structures, and tissue inhibitor of metalloproteinase-1 (TIMP-1), which regulates MMP activity. This study aims to investigate how these proteins correlate with the progression of ARN.
Methods: We analyzed aqueous humor samples from 33 patients with ARN and 23 control patients with virus-negative uveitis.
