[PMID: 38891648 PMCID: PMC11171346 DOI: 10.3390/ani14111600] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 05/24/2024] [Accepted: 05/25/2024] [Indexed: 06/21/2024] Open
Abstract
Acute hepatopancreatic necrosis disease (AHPND) poses a significant threat to shrimp aquaculture worldwide, necessitating the accurate and rapid detection of the pathogens. However, the increasing number of Vibrio species that cause the disease makes diagnosis and control more difficult. This study focuses on developing a monoclonal antibody against the Photorhabdus insect-related (Pir) toxin B (PirB), a pivotal virulence factor in AHPND-causing Vibrio, and establishing a colloidal gold immunochromatographic assay for the enhanced early diagnosis and monitoring of AHPND. Monoclonal antibodies targeting PirB were developed and utilized in the preparation of colloidal-gold-labeled antibodies for the immunochromatographic assay. The specificity and sensitivity of the assay were evaluated through various tests, including antibody subclass detection, affinity detection, and optimal labeling efficiency assessment. The developed PirB immunochromatographic test strips exhibited a good specificity, as demonstrated by the positive detection of AHPND-causing Vibrio and negative results for non-AHPND-causing Vibrio. The study highlights the potential of the developed monoclonal antibody and immunochromatographic assay for the effective detection of AHPND-causing Vibrio. Further optimization is needed to enhance the sensitivity of the test strips for improved practical applications in disease prevention and control in shrimp aquaculture.

Abstract
Background Generally, enterococci bacteria cause nosocomial infections and are major indicators of bacterial contamination in marine bathing beach. However, a method for the rapid and simultaneous detection of multiple pathogenic enterococci has not been developed on account of the wide variety of pathogenic enterococci and their existence in complex matrices. Methods Immunoinformatics tools were used to design a multi-epitope antigen for the detection of various pathogenic enterococci by using the sequence of dltD gene on enterococci lipoteichoic acid (LTA) surface, which is associated with toxicological effects. The multi-epitopes included enterococci such as Enterococcus faecalis, E. gallinarum, E. raffinosus, E. durans, E. faecium, E. hirae, E. thailandicus, E. casseliflavus, E. avium, E. mundtii, E. lactis, E. solitarius, E. pseudoavium, and E. malodoratum. Microscale thermophoresis (MST) and western blot were carried out to detect the affinity between multi-epitope antigens and antibodies and between multi-epitope antibodies and bacteria. Furthermore, the detection of pathogenic enterococci was carried out by using immunomagnetic beads (IMBs) and immune chromatographic test strip (ICTS). Results The multi-epitope antibody had a satisfactory affinity to the antigen and enterococci. IMBs and ICTS were detected with a minimum of 101 CFU/mL and showed incompatibility for Vibrio parahemolyticus, V. vulnifcus, V. harveyi, V. anguillarum, and Edwardsiella tarda. Implication The present study demonstrated that the multi-epitope antigens exhibited excellent specificity and sensitivity, making them highly suitable for efficient on-site screening of enterococci bacteria in marine bathing beaches.

Abstract
Acute hepatopancreatic necrosis disease (AHPND) is a contagious disease for the shrimp cultivation, thus early detection of disease is an unmet need. This present study documented for the first time a simple lateral flow immunoassay (LFIA) strip using polyclonal antibodies was created for the rapid detection both of PirAvp and PirBvp protein simultaneously. LFIA method based on the principle of sandwich format. The label is the colloidal gold. The polyclonal antibody was conjugated with the colloidal gold acting as biorecognition element and coated onto the conjugate pad. The rabbit anti-Pirvp, anti-PirBvp antibodies, and goat anti-rabbit IgG antibody were separately sprayed onto a nitrocellulose membrane to form two test lines and one control line, respectively. The appearance of red bands at the control line and the test line indicated a positive result. A single coloured band at control area indicated a negative result. The limit of detection of LFIA was found to be 125 ng, which could be visually detected by naked eye within 15 min. There was no cross-reactivity observed with VPnon-AHPND. Furthermore, the sensitivity and specificity of LFIA were 94.0% and 98.0%, respectively. The developed test strip could be a game changer for early and in situ diagnosis of AHPND.

Abstract
BACKGROUND Acute hepatopancreatic necrosis disease (AHPND) is caused by toxin-producing strains of Vibrio parahaemolyticus which contain deadly binary toxins PirAvp and PirBvp encoded in pVA1 plasmid. The polyclonal antibodies against PirBvp protein could be used to develop immunochromatographic test strip for in-field diagnosis of AHPND. RESULTS In this study, PirBvp gene was amplified, cloned, and expressed in E. coli. The expressed protein was detected by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blot probed with 6xHis antibodies. Then, the recombinant PirBvp (rPirBvp) was purified using Ni-Sepharose column. Rabbits were immunized with the purified rPirBvp, and produced antibodies were analyzed using Ouchterlony double immunodiffusion. The antibody titration and antibody purification were performed by ELISA and affinity chromatography, respectively. Finally, antibody specificity and sensitivity were evaluated by dot blotting. The present study showed a high titer of polyclonal antibodies in rabbit serum after immunization and the titer increased steadily during the immunization schedule. The highest titer of antibody reached up to 2,560,000 with LOD of 0.1 ng/mL. The purified antibodies showed no cross-reactivity with proteins from other Vibrio species, and the detection threshold ranged from 6.25 to 12.5 ng toxin/dot. CONCLUSION This study highlights the production of high titer and specific polyclonal antibodies as an initial material towards the development of lateral-flow strip test.

Abstract
The main goal of this work is to develop an economical, portable, disposable, and reliable point of care paper biosensor based on visualization, which can be used to detect viruses, bacteria, and proteins. However, the sensitivity of immunochromatography test (ICT) strips based on nitrocellulose to target detection has always been a problem. Here, we use an electrospun nitrocellulose (ENC) fiber membrane instead of traditional nitrocellulose fiber membrane to construct ICT strips for early pregnancy detection. By proper selection of the diameter of the ENC fiber to adjust the pore size, porosity, and morphology of the membrane, ICT strips with low flow rate and high protein loading were obtained. Based on these properties, a convenient and sensitive method for the colorimetric determination of human chorionic gonadotropin was developed. Under the optimal conditions, the detection limit of ICT based on ENC membrane is 10 mIU mL-1 (S/N = 3), the linear detection range is 5-1000 mIU mL-1, and the linear relationship is Y = 0.0434 X - 0.0136 (R2 = 0.9802). In addition, the test strip has good specificity and stability, and will not produce false-positive results. Graphical abstract.
