[PMID: 38793692 PMCID: PMC11126125 DOI: 10.3390/v16050811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 05/14/2024] [Accepted: 05/17/2024] [Indexed: 05/26/2024] Open
Abstract
Duck Tembusu Virus (DTMUV) is a pathogen of the Flaviviridae family that causes infections in poultry, leading to significant economic losses in the duck farming industry in recent years. Ducks infected with this virus exhibit clinical symptoms such as decreased egg production and neurological disorders, along with serious consequences such as ovarian hemorrhage, organ enlargement, and necrosis. Variations in morbidity and mortality rates exist across different age groups of ducks. It is worth noting that DTMUV is not limited to ducks alone; it can also spread to other poultry such as chickens and geese, and antibodies related to DTMUV have even been found in duck farm workers, suggesting a potential risk of zoonotic transmission. This article provides a detailed overview of DTMUV research, delving into its genomic characteristics, vaccines, and the interplay with host immune responses. These in-depth research findings contribute to a more comprehensive understanding of the virus's transmission mechanism and pathogenic process, offering crucial scientific support for epidemic prevention and control.

Rapid detection of mexX in Pseudomonas aeruginosa based on CRISPR-Cas13a coupled with recombinase polymerase amplification. Front Microbiol 2024; 15:1341179. [PMID: 38357344 PMCID: PMC10864651 DOI: 10.3389/fmicb.2024.1341179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Accepted: 01/09/2024] [Indexed: 02/16/2024] Open
Abstract
The principal pathogen responsible for chronic urinary tract infections, immunocompromised hosts, and cystic fibrosis patients is Pseudomonas aeruginosa, which is difficult to eradicate. Due to the extensive use of antibiotics, multidrug-resistant P. aeruginosa has evolved, complicating clinical therapy. Therefore, a rapid and efficient approach for detecting P. aeruginosa strains and their resistance genes is necessary for early clinical diagnosis and appropriate treatment. This study combines recombinase polymerase amplification (RPA) and clustered regularly interspaced short palindromic repeats-association protein 13a (CRISPR-Cas13a) to establish a one-tube and two-step reaction systems for detecting the mexX gene in P. aeruginosa. The test times for one-tube and two-step RPA-Cas13a methods were 5 and 40 min (including a 30 min RPA amplification reaction), respectively. Both methods outperform Quantitative Real-time Polymerase Chain Reactions (qRT-PCR) and traditional PCR. The limit of detection (LoD) of P. aeruginosa genome in one-tube and two-step RPA-Cas13a is 10 aM and 1 aM, respectively. Meanwhile, the designed primers have a high specificity for P. aeruginosa mexX gene. These two methods were also verified with actual samples isolated from industrial settings and demonstrated great accuracy. Furthermore, the results of the two-step RPA-Cas13a assay could also be visualized using a commercial lateral flow dipstick with a LoD of 10 fM, which is a useful adjunt to the gold-standard qRT-PCR assay in field detection. Taken together, the procedure developed in this study using RPA and CRISPR-Cas13a provides a simple and fast way for detecting resistance genes.

Point-of-Care Testing for Norovirus Typing Using CRISPR/Cas12a Combined with Reverse Transcription Recombinase Polymerase Amplification. Bioconjug Chem 2023; 34:1147-1156.

Abstract
Noroviruses (NoVs) are one of the leading causes of acute gastroenteritis in humans. This study combined reverse transcription recombinase polymerase amplification (RT-RPA) with a clustered regularly interspaced short palindromic repeat/CRISPR-associated protein (CRISPR/Cas) nucleic acid detection system to develop a point-of-care testing (POCT) technology for typing NoVs. The detection can be completed within 35 min at 37 °C, covering each genotype of genogroup I (GI) and II (GII) NoVs. The sensitivity of this method is 10 copies/μL for GI and 1 copy/μL for GII NoV plasmids. For the detection of clinical samples, the detection results of this method for NoV infected samples are consistent with the RT-qPCR detection method in the laboratory, and this detection method has no cross-reactivity with rotavirus and adenovirus. Therefore, the detection method established in this study enables the diagnosis and screening of suspected patients and close contacts by POCT, which is important for the timely identification and control of NoV outbreaks. In addition, the typing detection of GI and GII NoVs can achieve a precise diagnosis and treatment of patients infected with NoVs.

Abstract
Constructing an ultrasensitive CRISPR/Cas-based biosensing strategy is highly significant for the detection of trace targets. Here we presented a dual-amplified biosensing method based on CRISPR/Cas13a-triggered Cas12a, namely, Cas13a-12a amplification. As proof-of-principle, the developed strategy was used for miRNA-155 detection. The target bound to the Cas13a-crRNA complex and activated the cleavage activity of Cas13a for cleaving uracil ribonucleotides (rU) in the bulge structure of blocker strand (BS), resulting in the release of primer strand (PS) from the BS modified on magnetic beads. Then, the released PS activated the cleavage activity of Cas12a to cleave single-strand DNA reporter probes, producing a significantly increased fluorescent signal. The detection limit of the Cas13a-12a amplification using synthetic miRNA-155 was as low as 0.35 fM, which was much lower than that of the only Cas13a-based assay. The applied performance of this amplification strategy was verified by accurately quantifying miRNA-155 expression levels in different cancer patients. Therefore, the developed strategy offers a supersensitive and highly specific miRNAs sensing platform for clinical application.

Abstract
Goose astrovirus (GAstV) characterized by articular and visceral gout, is an emerging pathogen with a wide distribution on mainland China, leading to serious economic losses in the goose-raising industry. Because vaccines to prevent GAstV infections are not available currently, early diagnosis is critical when treating symptomatic geese and in preventing GAstV transmission. In this context, a highly sensitive indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) based on a monoclonal antibody (mAb) to detect GAstV-specific antibodies from geese was developed, and the detections were optimized. A series of experiments proved that the ic-ELISA shows excellent diagnostic performance and discriminatory power with high sensitivity and specificity. The ic-ELISA for GAstV detection was applied on 67 field serum samples, and comparing the detection results with the virus neutralization test verified the accuracy of the ic-ELISA. The correlation coefficient between the ic-ELISA and the virus neutralization test was 80%, demonstrating the proposed ic-ELISA method could be a useful and effective tool for the diagnostic, serological epidemiological investigation and immune monitoring of the GAstV in goose-producing regions.

Abstract
Early and rapid diagnosis of pathogens is important for the prevention and control of epidemic disease. The polymerase chain reaction (PCR) technique requires expensive instrument control, a special test site, complex solution treatment steps and professional operation, which can limit its application in practice. The pathogen detection method based on the clustered regularly interspaced short palindromic repeats (CRISPRs) and CRISPR-associated protein (CRISPR/Cas) system is characterized by strong specificity, high sensitivity and convenience for detection, which is more suitable for practical applications. This article first reviews the CRISPR/Cas system, and then introduces the application of the two types of systems represented by Type II (cas9), Type V (cas12a, cas12b, cas14a) and Type VI (cas13a) in pathogen detection. Finally, challenges and prospects are proposed.
