Abstract
Infectious bovine rhinotracheitis virus (IBRV) can cause various degrees of symptoms in the respiratory system, reproductive system, and whole body of cattle. It also can lead to persistent and latent infection in cattle, posing a challenge to timely control of infectious bovine rhinotracheitis (IBR) in farms and causing large financial losses in the global cattle industry. Therefore, the goal of this study was to establish a rapid, simple, and accurate method that can detect IBRV in order to facilitate the control and eradication of IBR in cattle. We combined recombinant polymerase amplification (RPA) with a closed vertical flow visualization strip (VF) and established an RPA-VF assay that targets the thymidine kinase (TK) gene to rapidly detect IBRV. This method (reaction at 42°C for 25 min) was able to detect a minimum of 3.8 × 101 copies/μL of positive plasmid and 1.09 × 101 50% tissue culture infective dose (TCID50) of the IBRV. This assay has high specificity for IBRV and does not cross-react with other respiratory pathogens in cattle. The concordance between the RPA-VF assay and the gold standard was 100%. In addition, this assay was also suitable for the detection of DNA from clinical samples extracted by a simple method (heating at 95°C for 5 min), which can achieve the rapid detection of clinical samples in the field. Overall, the present sensitivity, specificity, and clinical applicability assessments indicated that the RPA-VF assay we developed can be utilized as a quick and accurate on-site test for IBRV detection in farms. IMPORTANCE IBRV causes different degrees of clinical symptoms in cattle and poses a great threat to the cattle industry. The infection is persistent and latent, and the elimination of IBRV in infected herds is difficult. A rapid, simple, and accurate method to detect IBRV is therefore vital to control and eradicate IBR. Combining RPA with an VF, we established an RPA-VF assay for the rapid detection of IBRV, which can complete the test of clinical samples in 35 min. The assay shows good sensitivity, specificity, and clinical applicability and can be used as an on-site test for IBRV in farms.

Abstract
Bovine herpesvirus 1 (BHV-1), an important pathogen of cattle, can cause severe clinical syndromes including respiratory disease, genital disease, and late-term abortions, as well as neurological and systemic disease in cattle. For assessing the prevalence of BHV-1 infection in mainland China, a systematic review and meta-analysis was conducted. In this systematic review and meta-analysis, we searched English and Chinese literature databases for published paper regarding the prevalence of BHV-1 in cattle in China from inception to May 20, 2018. Search strings included if they reported the cattle samples of more than 30 cattle and provided information that allowed us to establish the prevalence of BHV-1. Moreover, we excluded repeated studies, reviews, other hosts studies, as well as studies with inconsistent data, incomplete information or only provided prevalence data, and out of mainland China data. We extracted how many cattle have BHV-1 infection from the obtained studies, moreover, and calculated pooled prevalence of BHV-1 infection in cattle. The data of 41 articles (including data on 43,441 cattle) are compliant with the standards. The pooled prevalence of BHV-1 in cattle in China was 40%, the pooled prevalence of BHV-1 in cattle from Northeast China (24%) was significant lower than those from other regions. In addition, the prevalence of BHV-1 was associated with publication time of paper, detection methods, age of cattle, and clinical symptoms (pneumonia, abortion etc.).Our findings suggest that BHV-1 is common in cattle in mainland China. It is necessary to monitor the prevalence of BHV-1 in cattle and the powerful and effective regulatory measures should be taken out to prevent the spread of BHV-1.

[PMID: 26123370 DOI: 10.1016/j.vetmic.2015.06.009] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2015] [Revised: 06/08/2015] [Accepted: 06/11/2015] [Indexed: 11/17/2022]
Abstract
Although modified-live multivalent vaccines, such as PregGuard GOLD and Bovi-Shield Gold, have been used routinely in both beef and dairy cattle in the US, abortion and respiratory diseases still occasionally occur following vaccination. To determine whether the antibody induced by the multivalent vaccine can recognize BHV-1 isolates from aborted animals, BHV-1 antibody titer was evaluated with two isolates from abortion cases and two vaccine BHV-1 viruses. Cattle serum was collected from a dairy herd that was vaccinated annually with Bovi-Shield Gold 5 vaccine. Among the 28 cattle tested, no statistical significant difference in serum neutralization titer was observed when test virus was either vaccine virus or clinical isolates. It suggests that the BHV-1 antibody from the vaccinated cattle can recognize both the vaccine virus and clinical isolates. However, it is noticed that cows at 5 years old or older had a significantly lower BHV-1 antibody titer on average than the average of SN titer in 3 year-old cows. Similarly, cows at 5 years or older had a significantly lower BVDV antibody titer than cows at about 2 years of age. In addition, cattle vaccinated within 0-2 months had a significantly higher BHV-1 titer than those that received vaccination 6 months or greater prior to titer measurement. In contrast, cattle that received a vaccination 6 months prior had a significantly higher anti-BVDV antibody titer than those vaccinated within 1-2 months. The BVDV antibody titers remained relatively unchanged between 6 months and 1 year post-vaccination. Our study suggests little antigenic variation exists between BHV-1 disease isolates and BHV-1 of the multivalent vaccines. In addition, BHV-1 antibody titer is relatively lower at 6 months post vaccination in those tested animals. However, the BVDV antibody titer remained relatively high after 6 months from time of vaccination.
