Abstract
The lethality of the bovine viral diarrhea virus (BVDV) in cattle involves inapparent infection and various, typically subclinical, syndromes. Cattle of all ages are vulnerable to infection with the virus. It also causes considerable economic losses, primarily due to reduced reproductive performance. In the absence of treatment that can completely cure infected animals, detection of BVDV relies on highly sensitive and selective diagnosis methods. In this study, an electrochemical detection system was developed as a useful and sensitive system for the detection of BVDV to suggest the direction of diagnostic technology through the development of conductive nanoparticle synthesis. As a countermeasure, a more sensitive and rapid BVDV detection system was developed using the synthesis of electroconductive nanomaterials black phosphorus (BP) and gold nanoparticle (AuNP). To increase the conductivity effect, AuNP was synthesized on the BP surface, and the stability of BP was improved by using dopamine self-polymerization. Moreover, its characterizations, electrical conductivity, selectivity, and sensitivity toward BVDV also have been investigated. The BP@AuNP-peptide-based BVDV electrochemical sensor exhibited a low detection limit of 0.59 copies mL-1 with high selectivity and long-term stability (retaining 95% of its initial performance over 30 days).

Development and evaluation of real-time RT-PCR using ear hair for specific detection of sheep persistently infected with border disease virus (BDV). J Virol Methods 2019; 269:55-63. [PMID: 30951788 DOI: 10.1016/j.jviromet.2019.04.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2018] [Revised: 04/01/2019] [Accepted: 04/01/2019] [Indexed: 11/15/2022]
Abstract
The aim of this study was to develop an improved border disease virus (BDV) specific real time RT-PCR and to evaluate its performance on manually plucked hairs from sheep persistently infected with BDV that may act as a non-invasive alternate sample. The BDV real time RT-PCR assay reported here showed a high analytical sensitivity (100.6 TCID50/ml), specificity (no reactivity with BVDV-1, BVDV-2, HoBi-like pestivirus and CSFV) and reproducibility. When the assay was validated on 210 samples from BDV-infected and uninfected sheep, it showed a 100% diagnostic sensitivity and specificity with virus isolation. Further evaluation of the assay on manually plucked hair follicles from ear (mid-lateral, mid-medial) and tail tip from sheep persistently infected with BDV showed that a minimum of 20 hair follicles need to be tested for correct diagnosis of BDV. The BDV load was comparatively higher in hairs from mid-medial ear than those from other tested locations. Evaluation on other samples from PI sheep demonstrated that the test performance was similar to that of pestivirus generic real-time RT-PCR, but improved than the currently available BDV specific real-time RT-PCR. Although more number of PI animals need to be evaluated, the results of the study showed that manually plucked hairs from mid-medial ear pinna is a suitable alternative sample in real-time RT-PCR for detection of BDV persistently infected sheep. Use of the non-invasive ear hair samples and the improved BDV specific real-time RT-PCR reported here may be useful for BDV surveillance in several sheep rearing countries.

A newly developed BVDV-1 RT-qPCR Taqman assay based on Italian isolates: evaluation as a diagnostic tool. Folia Microbiol (Praha) 2017; 62:279-286. [PMID: 28127668 DOI: 10.1007/s12223-017-0497-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2016] [Accepted: 01/15/2017] [Indexed: 01/01/2023]
Abstract
A single-step TaqMan® RT-qPCR was developed for the detection of bovine viral diarrhea virus type 1 (BVDV-1), an important pathogen of cattle worldwide. The assay was based on conserved 5'UTR sequences of Italian BVDV-1 isolates. In order to establish a diagnostic protocol which simplifies sample collection and processing, the assay was tested on a variety of biological specimens collected from persistently infected calves. The samples analyzed included PBMCs, plasma, dry blood, ear notch and hair bulb. Time and costs required for the analysis of each type of specimen were compared. The RT-qPCR, whose lower limit of detection was 100 copies of viral RNA (1 TCID50), correctly identified all PI animals, irrespective of the type of specimen. The highest copy numbers were obtained from the RNAs extracted from PBMCs, ear notches and hair bulbs. Hair bulb-supernatants directly used as a template allowed identification of all PI animals. In conclusion, based on time and cost evaluation, the most effective and efficient protocol was the one based on the direct analysis of hair bulb-supernatants, avoiding the RNA extraction step.

Efficacy of multivalent, modified- live virus (MLV) vaccines administered to early weaned beef calves subsequently challenged with virulent Bovine viral diarrhea virus type 2. BMC Vet Res 2015; 11:29. [PMID: 25880998 PMCID: PMC4334402 DOI: 10.1186/s12917-015-0342-8] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2014] [Accepted: 01/29/2015] [Indexed: 11/29/2022] Open
Abstract
Background Vaccination of young calves against Bovine viral diarrhea virus (BVDV) is desirable in dairy and beef operations to reduce clinical disease and prevent spread of the virus among cattle. Although protection from clinical disease by multivalent, modified-live virus (MLV) vaccines has been demonstrated, the ability of MLV vaccines to prevent viremia and viral shedding in young calves possessing passive immunity is not known. The purpose of this study was to compare the ability of three different MLV vaccines to prevent clinical disease, viremia, and virus shedding in early weaned beef calves possessing maternal immunity that were vaccinated once at 45 days prior to challenge with virulent BVDV 2. Results At 45 days following vaccination, calves that received vaccines B and C had significantly higher BVDV 1 and BVDV 2 serum antibody titers compared with control calves. Serum antibody titers for BVDV 1 and BVDV 2 were not significantly different between control calves and calves that received vaccine D. Following BVDV 2 challenge, a higher proportion of control calves and calves that received vaccine D presented viremia and shed virus compared with calves that received vaccines B and C. Rectal temperatures and clinical scores were not significantly different between groups at any time period. Calves that received vaccines B and C had significantly higher mean body weights at BVDV 2 challenge and at the end of the study compared with control calves. Conclusions Moderate to low maternally-derived BVDV antibody levels protected all calves against severe clinical disease after challenge with virulent BVDV 2. Vaccines B and C induced a greater antibody response to BVDV 1 and BVDV 2, and resulted in reduced viremia and virus shedding in vaccinated calves after challenge indicating a greater efficacy in preventing virus transmission and reducing negative effects of viremia.
