High-throughput analysis of anti-poliovirus neutralization antibody titre in human serum by the pseudovirus neutralization test. Sci Rep 2022; 12:16074. [PMID: 36167892 PMCID: PMC9514167 DOI: 10.1038/s41598-022-20544-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 09/14/2022] [Indexed: 12/02/2022] Open
Abstract
To monitor vulnerability of countries to poliovirus (PV) outbreaks, serosurveillance of anti-PV neutralization antibody is conducted by conventional PV neutralization test (cPNT), which uses live PV strains. We previously developed a pseudovirus PV neutralization test (pPNT) as an alternative to cPNT, which uses PV pseudovirus that expresses luciferase as a reporter in the infection without producing infectious PV. In the present study, we established a high-throughput pPNT (HTpPNT) for a large-scale serosurveillance. The HTpPNT system was evaluated with 600 human serum samples obtained from a broad range of age groups of healthy volunteers (ages of 0–89 years). HTpPNT showed high correlation with cPNT (R2 for anti-type 1, 2, and 3 PV neutralization antibody titres are 0.90, 0.84, and 0.90, respectively). By using HTpPNT, we analyzed relative neutralizing antibody titre of the sera against a type 1 PV wild-type strain (Mahoney strain) to that against the type 1 Sabin strain. As a result, a correlation between the age (≥ 60 years) and the relative neutralizing antibody titre was observed (n = 15–16, P = 0.0000023–0.041), while the types of PV vaccine (i.e., oral PV vaccine and Sabin strain-based IPV) had no effect. HTpPNT would serve as a useful alternative to cPNT in a large-scale serosurveillance.

Clin Chim Acta 2020; 512:172-178. [PMID: 33181150 DOI: 10.1016/j.cca.2020.11.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 10/23/2020] [Accepted: 11/03/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Astrovirus (AstV), Sapovirus (SaV) and Poliovirus (PV) are important pathogens that cause infections in children under five years of age. It is a very important task to systematically monitor and evaluate the diagnostic performance of these viruses in clinical laboratories. METHODS In our study, we performed a multicenter evaluation study among 21 laboratories across China using simulated stool samples spiked with self-designed AstV, SaV and PV pseudoviral particles. RESULTS The testing capability of 80.0% (16/20, AstV), 52.6% (10/19, SaV), and 25.0% (2/8, PV) of the participating laboratories were found to be "competent" in reporting correct results for all samples. The main type of errors were false negatives. None of the laboratories identified the subtypes of AstV and SaV, and six laboratories specifically identified the subtypes of PV. Lacking of well-trained personnel and adequate funding were the main challenges. From the questionnaire results, 55.6% laboratories (10/18) believe that training personnel could improve the laboratory testing performance. CONCLUSIONS The laboratories showed a competent diagnostic performance for AstV, but inferior diagnostic performances for SaV and PV. Sensitivity of detection and the ability for virus typing should be improved clinically. Professional and standardized personnel training is urgently needed to further improve laboratory performance.
