Abstract
Lablab purpureus from the Fabaceae family has been reported to have antiviral properties and used in traditional medical systems like ayurveda and Chinese medicine and has been employed to treat a variety of illnesses including cholera, food poisoning, diarrhea, and phlegmatic diseases. The bovine alphaherpesvirus-1 (BoHV-1) is notorious for causing significant harm to the veterinary and agriculture industries. The removal of the contagious BoHV-1 from host organs, particularly in those reservoir creatures, has required the use of antiviral drugs that target infected cells. This study developed LP-CuO NPs from methanolic crude extracts, and FTIR, SEM, and EDX analyses were used to confirm their formation. SEM analysis revealed that the LP-CuO NPs had a spherical shape with particle sizes between 22 and 30 nm. Energy-dispersive X-ray pattern analysis revealed the presence of only copper and oxide ions. By preventing viral cytopathic effects in the Madin-Darby bovine kidney cell line, the methanolic extract of Lablab purpureus and LP-CuO NPs demonstrated a remarkable dose-dependent anti-BoHV-1 action in vitro. Furthermore, molecular docking and molecular dynamics simulation studies of bio-actives from Lablab purpureus against the BoHV-1 viral envelope glycoprotein disclosed effective interactions between all phytochemicals and the protein, although kievitone was found to have the highest binding affinity, with the greatest number of interactions, which was also validated with molecular dynamics simulation studies. Understanding the chemical reactivity qualities of the four ligands was taken into consideration facilitated by the global and local descriptors, which aimed to predict the chemical reactivity descriptors of the studied molecules through the conceptual DFT methodology, which, along with ADMET finding, support the in vitro and in silico results.

Abstract
Bovine Alphaherpesvirus 1 (BoHV-1) is one of the major respiratory pathogens in cattle worldwide. Infection often leads to a compromised host immune response that contributes to the development of the polymicrobial disease known as “bovine respiratory disease”. After an initial transient phase of immunosuppression, cattle recover from the disease. This is due to the development of both innate and adaptive immune responses. With respect to adaptive immunity, both humoral and cell-mediated immunity are required to control infection. Thus, several BoHV-1 vaccines are designed to trigger both branches of the adaptive immune system. In this review, we summarize the current knowledge on cell-mediated immune responses directed against BoHV-1 infection and vaccination.

Abstract
The aim of this study was molecular identification of bovine leukemia virus and possible co-infection with bovine respiratory disease complex (BRDC) viral agents in Mexican dairy herds. We collected 533 blood samples from cattle vaccinated against the BRDC virus in 9 states across Mexico. Peripheral blood leukocytes were removed and genetic material was extracted to detect bovine leukemia virus (BLV), bovine herpesvirus 1 (BoHV-1), bovine viral diarrhea virus (BVDV), bovine parainfluenza virus 3 (BPIV-3), and bovine respiratory syncytial virus (BRSV) infection using polymerase chain reaction. We identified high BLV infection rates in 270 cattle (50.65%). One hundred and thirty-three cows (24.95%) tested positive for BoHV-1, of which 65 samples were positive for both viruses (BoHV-1 and BLV) and 68 were only positive for BoHV-1. Only 4 samples tested positive for BPIV-3 and no sample was positive for BVDV or BRSV. Relative risk and odds ratio analyses did not identify that the presence of BLV infection favors BoHV-1 co-infection in vaccinated herds.

Abstract
Bovine alphaherpesvirus 1 (BoHV-1) is a persistent and recurring disease that affects cattle worldwide. It is a major contributor to bovine respiratory disease and reproductive failure in the US. A major complication of BoHV-1 arises from the lifelong latent infection established in the sensory ganglia of the peripheral nervous system following acute infection. Lifelong latency is marked by periodic reactivation from latency that leads to virus transmission and transient immunosuppression. Physiological and environmental stress, along with hormone fluctuations, can drive virus reactivation from latency, allowing the virus to spread rapidly. This review discusses the mechanisms of the latency/reactivation cycle, with particular emphasis on how different hormones directly regulate BoHV-1 gene expression and productive infection. Glucocorticoids, including the synthetic corticosteroid dexamethasone, are major effectors of the stress response. Stress directly regulates BoHV-1 gene expression through multiple pathways, including β-catenin dependent Wnt signaling, and the glucocorticoid receptor. Related type 1 nuclear hormone receptors, the androgen and progesterone receptors, also drive BoHV-1 gene expression and productive infection. These receptors form feed-forward transcription loops with the stress-induced Krüppel-like transcription factors KLF4 and KLF15. Understanding these molecular pathways is critical for developing novel therapeutics designed to block reactivation and reduce virus spread and disease.

Abstract
Bovine Respiratory Syncytial virus (BRSV) and Bovine Parainfluenza 3 virus (BPIV3) are closely related viruses involved in and both important pathogens within bovine respiratory disease (BRD), a major cause of morbidity with economic losses in cattle populations around the world. The two viruses share characteristics such as morphology and replication strategy with each other and with their counterparts in humans, HRSV and HPIV3. Therefore, BRSV and BPIV3 infections in cattle are considered useful animal models for HRSV and HPIV3 infections in humans.The interaction between the viruses and the different branches of the host's immune system is rather complex. Neutralizing antibodies seem to be a correlate of protection against severe disease, and cell-mediated immunity is thought to be essential for virus clearance following acute infection. On the other hand, the host's immune response considerably contributes to the tissue damage in the upper respiratory tract.BRSV and BPIV3 also have similar pathobiological and epidemiological features. Therefore, combination vaccines against both viruses are very common and a variety of traditional live attenuated and inactivated BRSV and BPIV3 vaccines are commercially available.

Immunofluorescence and molecular diagnosis of bovine respiratory syncytial virus and bovine parainfluenza virus in the naturally infected young cattle and buffaloes from India.

Abstract
Pneumonia in bovines is a multifactorial disease manifestation leading to heavy economic losses. Infections of bovine respiratory syncytial virus (BRSV) and bovine parainfluenza virus-3 (BPI-3) are among the important contributing factors for the development of pneumonia in young animals. These viral agents either primarily cause pneumonia or predispose animals to the development of pneumonia. Although, the role of BRSV and BPI-3 in the pathogenesis of pneumonia is well established, there are no reports of involvement of BRSV and BPI-3 from Indian cattle and buffaloes suffering from pneumonia. In the present investigation, we performed postmortem examinations of 406 cattle and buffaloes, which were below twelve months of age. Out of 406 cases, twelve (2.95%) cases were positive for BRSV and fifteen (3.69%) cases were positive for BPI-3, screened by reverse transcriptase polymerase chain reaction (RT-PCR). Further, positive cases were confirmed by sequence analysis of RT-PCR amplicons and direct immunofluorescence antibody test (d-FAT) in paraffin-embedded lung tissue sections. BRSV positive cases revealed characteristic findings of bronchiolar epithelial necrosis, thickened alveolar septa by mononuclear cells infiltration and edema; alveolar lumens were filled with mononuclear cells and numerous syncytial cells were seen having intracytoplasmic inclusions. The BRSV antigen distribution was found to be in bronchiolar and alveolar epithelium and syncytial cells in the lung sections. In fifteen cases, where BPI-3 was detected, bronchointerstitial pneumonia in the majority of cases with thickened alveolar septa by mild macrophage infiltration, hyperplasia of type-II pneumocytes and bronchiolar necrosis along with syncytial cells having intracytoplasmic inclusions in the majority of cases were observed. The BPI-3 antigen distribution was found to be in bronchiolar and alveolar epithelium and syncytial cells in the lung sections. RT-PCR amplicons of BRSV and BPI-3 obtained were sequenced and their analysis showed homology with already available sequences in the NCBI database. It is the first report of detection of BRSV and BPI-3 from pneumonic cases by RT-PCR and d-FAT from cattle and buffaloes of India, indicating the need for more epidemiological studies. BRSV and BPI-3 induce primary pneumonia. Syncytia with cytoplasmic inclusion was seen. RT-PCR and dFAT are confirmatory diagnosis.

Abstract
Infection of cattle by bovine herpesvirus 1 (BoHV-1) can culminate in upper respiratory tract disorders, conjunctivitis, or genital disorders. Infection also consistently leads to transient immune-suppression. BoHV-1 is the number one infectious agent in cattle that is associated with abortions in cattle. BoHV-1, as other α-herpesvirinae subfamily members, establishes latency in sensory neurons. Stressful stimuli, mimicked by the synthetic corticosteroid dexamethasone, consistently induce reactivation from latency in latently infected calves and rabbits. Increased corticosteroid levels due to stress have a two-pronged effect on reactivation from latency by: (1) directly stimulating viral gene expression and replication, and (2) impairing antiviral immune responses, thus enhancing virus spread and transmission. BoHV-1 encodes several proteins, bICP0, bICP27, gG, UL49.5, and VP8, which interfere with key antiviral innate immune responses in the absence of other viral genes. Furthermore, the ability of BoHV-1 to infect lymphocytes and induce apoptosis, in particular CD4+ T cells, has negative impacts on immune responses during acute infection. BoHV-1 induced immune-suppression can initiate the poly-microbial disorder known as bovine respiratory disease complex, which costs the US cattle industry more than one billion dollars annually. Furthermore, interfering with antiviral responses may promote viral spread to ovaries and the developing fetus, thus enhancing reproductive issues associated with BoHV-1 infection of cows or pregnant cows. The focus of this review is to describe the known mechanisms, direct and indirect, by which BoHV-1 interferes with antiviral immune responses during the course of infection.

Abstract
Coronaviruses, including bovine coronavirus (BCoV), are etiologically associated with enteric and respiratory disease across a wide range of mammalian and avian species. The role of BCoV in calfhood diarrhea is well-established, but its role in the bovine respiratory disease complex (BRDC) has been controversial. This review re-examines the evidence that BCoV is a significant pathogen in the BRDC.

Abstract
Bovine Respiratory Disease (BRD) is a major source of economic loss within the agricultural industry. Vaccination against BRD-associated viruses does not offer complete immune protection and vaccine failure animals present potential routes for disease spread. Serological differentiation of infected from vaccinated animals (DIVA) is possible using antigen-deleted vaccines, but during virus outbreaks DIVA responses are masked by wild-type virus preventing accurate serodiagnosis. Previous work by the authors has established the potential for metabolomic profiling to reveal metabolites associated with systemic immune responses to vaccination. The current study builds on this work by demonstrating for the first time the potential to use plasma metabolite profiling to differentiate between vaccinated and non-vaccinated animals following infection-challenge. Male Holstein Friesian calves were intranasally vaccinated (Pfizer RISPOVAL®PI3+RSV) and subsequently challenged with Bovine Parainfluenza Virus type-3 (BPI3V) via nasal inoculation. Metabolomic plasma profiling revealed that viral challenge led to a shift in acquired plasma metabolite profiles from day 2 to 20 p.i., with 26 metabolites identified whose peak intensities were significantly different following viral challenge depending on vaccination status. Elevated levels of biliverdin and bilirubin and decreased 3-indolepropionic acid in non-vaccinated animals at day 6 p.i. may be associated with increased oxidative stress and reactive oxygen scavenging at periods of peak virus titre. During latter stages of infection, increased levels of N-[(3α,5β,12α)-3,12-dihydroxy-7,24-dioxocholan-24-yl]glycine and lysophosphatidycholine and decreased enterolactone in non-vaccinated animals may reflect suppression of innate immune response mechanisms and progression to adaptive immune responses. Levels of hexahydrohippurate were also shown to be significantly elevated in non-vaccinated animals from days 6 to 20 p.i. These findings demonstrate the potential of metabolomic profiling to identify plasma markers that can be employed in disease diagnostic applications to both differentially identify infected non-vaccinated animals during disease outbreaks and provide greater information on the health status of infected animals.

Abstract
Bovine herpesvirus 1 (BoHV-1) is 1 of several viruses considered to be causal agents of bovine abortion. The current retrospective study examined data on bovine abortion submissions from 5 veterinary diagnostic laboratories from 2000 to 2011. The objective of the study was to describe prevalence of BoHV-1-associated abortion in submissions at veterinary diagnostic laboratories. There were 3 specific aims: 1) to examine the proportion of BoHV-1-related abortions with the introduction of new diagnostic assays such as polymerase chain reaction (PCR), 2) to evaluate the agreement of the histopathology report of the abortion submissions and the result of the assay used, and 3) to evaluate if there was an association between farm history of vaccination against BoHV-1 and BoHV-1-positive abortion submissions. An extended Mantel-Haenszel χ(2) for linear trend was used to analyze the prevalence of BoHV-1 over the study period and showed that collectively there is evidence of an increase of positive BoHV-1 abortions (P < 0.001). The comparison of the proportion of BoHV-1-positive submissions pre- and postadoption of PCR was not significant (P = 0.25). Using Cohen kappa coefficient test of agreement, a kappa value of 0.81 (P < 0.001) was found, suggesting high agreement of lesions reported and assay result. It was found that using a χ(2) test, a P value of 0.068 for nonmatched data (i.e., a history of vaccination against BoHV-1 in the herd) was associated with reduced detection of BoHV-1-positive abortion submissions.

Abstract
Genome structural annotation, i.e., identification and demarcation of the boundaries for all the functional elements in a genome (e.g., genes, non-coding RNAs, proteins and regulatory elements), is a prerequisite for systems level analysis. Current genome annotation programs do not identify all of the functional elements of the genome, especially small non-coding RNAs (sRNAs). Whole genome transcriptome analysis is a complementary method to identify “novel” genes, small RNAs, regulatory regions, and operon structures, thus improving the structural annotation in bacteria. In particular, the identification of non-coding RNAs has revealed their widespread occurrence and functional importance in gene regulation, stress and virulence. However, very little is known about non-coding transcripts in Histophilus somni, one of the causative agents of Bovine Respiratory Disease (BRD) as well as bovine infertility, abortion, septicemia, arthritis, myocarditis, and thrombotic meningoencephalitis. In this study, we report a single nucleotide resolution transcriptome map of H. somni strain 2336 using RNA-Seq method. The RNA-Seq based transcriptome map identified 94 sRNAs in the H. somni genome of which 82 sRNAs were never predicted or reported in earlier studies. We also identified 38 novel potential protein coding open reading frames that were absent in the current genome annotation. The transcriptome map allowed the identification of 278 operon (total 730 genes) structures in the genome. When compared with the genome sequence of a non-virulent strain 129Pt, a disproportionate number of sRNAs (∼30%) were located in genomic region unique to strain 2336 (∼18% of the total genome). This observation suggests that a number of the newly identified sRNAs in strain 2336 may be involved in strain-specific adaptations.

Abstract
In contrast to mice or humans, cattle contain three beta interferon (IFN-β) genes with distinct transcriptional promoters suggesting IFN-β gene expression is not stimulated the same by different viruses. To test this hypothesis, we compared expression of the three IFN-β subtypes after infection with a RNA virus, Sendai, versus a large DNA virus, bovine herpesvirus 1 (BHV-1). Infection of low passage bovine kidney (BK) or established bovine kidney cells (CRIB) with Sendai virus has consistently led to high levels of IFN-β1 RNA. Conversely, infection of CRIB cells, but not BK cells, with BHV-1 increased IFN-β3 RNA levels and to a lesser extent the other two IFN-β subtypes. Inhibition of de novo protein synthesis with cycloheximide resulted in higher levels of IFN-β1 and IFN-β2 RNA levels after BHV-1 infection. Further studies demonstrated that BHV-1 immediate early and/or early genes were primarily responsible for inhibiting the IFN response in BK cells. The three bovine IFN-β promoters were cloned upstream of a reporter gene construct, and their properties analyzed in transient transfection assays. Only the IFN-β3 promoter was trans-activated by IRF3 (interferon responsive factor 3). IRF7 and double stranded RNA (polyI:C) stimulated IFN-β1 and IFN-β3 promoter activity, but not IFN-β2. Relative to the human IFN-β promoter, the IFN-β3 promoter contained fewer nucleotide differences in the positive regulatory domain III (PRD III), PRD IV, and PRD I compared to the IFN-β1 and IFN-β2 promoter. Collectively, these studies provide evidence that virus infection differentially stimulates expression of the three bovine IFN-β genes.

Virus Res 2011; 156:17-24. [PMID: 21215282 DOI: 10.1016/j.virusres.2010.12.010] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2010] [Revised: 12/21/2010] [Accepted: 12/21/2010] [Indexed: 11/17/2022]
Abstract
BHV-1 is an important pathogen of cattle. The infected cell protein 0 (bICP0) encoded by BHV-1 is an important regulatory protein because it is constitutively expressed and can activate all viral promoters. The mechanism by which bICP0 activates viral promoters is not well understood because bICP0 does not appear to be a sequence specific binding protein. A C(3)HC(4) zinc RING (really interesting novel gene) motif at the N-terminus of bICP0 has E3 ubiquitin ligase activity, which is important for activating viral gene expression and inhibiting interferon dependent transcription. Like other alpha-herpesvirinae ICP0 homologues, bICP0 is associated with promyelocytic leukemia (PML) protein-containing nuclear domains. During productive infection of cultured cells, BHV-1 induces degradation of the PML protein, which correlates with efficient productive infection. In this study, we demonstrated that a plasmid expressing bICP0 reduces steady state levels of the PML protein, and the C(3)HC(4) zinc RING finger is important for PML degradation. Surprisingly, bICP0 mutants with an intact C(3)HC(4) zinc RING finger that lack a nuclear localization signal also reduces steady PML protein levels. In addition, mutant bICP0 proteins that primarily localize to the cytoplasm induced morphological changes in transfected cells. During productive infection, bICP0 was detected in the cytoplasm of low-passage bovine kidney, but not established bovine kidney cells. These studies demonstrated that bICP0, even when not able to efficiently localize to the nucleus, was able to induce degradation of the PML protein and alter the morphology of transfected cells.

Abstract
Bovine herpesvirus 1 (BoHV-1) infected cell protein 0 (bICP0) is an important transcriptional regulatory protein that stimulates productive infection. In transient transfection assays, bICP0 also inhibits interferon dependent transcription. bICP0 can induce degradation of interferon stimulatory factor 3 (IRF3), a cellular transcription factor that is crucial for activating beta interferon (IFN-β) promoter activity. Recent studies also concluded that interactions between bICP0 and IRF7 inhibit trans-activation of IFN-β promoter activity. The C3HC4 zinc RING (really important new gene) finger located near the amino terminus of bICP0 is important for all known functions of bICP0. A recombinant virus that contains a single amino acid change in a well conserved cysteine residue of the C3HC4 zinc RING finger of bICP0 grows poorly in cultured cells, and does not reactivate from latency in cattle confirming that the C3HC4 zinc RING finger is crucial for viral growth and pathogenesis. A bICP0 deletion mutant does not induce plaques in permissive cells, but induces autophagy in a cell type dependent manner. In summary, the ability of bICP0 to stimulate productive infection, and repress IFN dependent transcription plays a crucial role in the BoHV-1 infection cycle.

Abstract
Mycoplasma bovis has emerged as an important pathogen of young intensively reared calves in North America. A variety of clinical diseases are associated with M bovis infections of calves, including respiratory disease, otitis media, arthritis, and some less common presentations. Clinical disease associated with M bovis often is chronic, debilitating, and poorly responsive to antimicrobial therapy. Current control measures are centered on reducing exposure to M bovis through contaminated milk or other sources, and nonspecific control measures to maximize respiratory defenses of the calf. This article focuses on the clinical and epidemiologic aspects of M bovis infections in young calves.

Abstract
Bovine herpesvirus 1 (BHV-1) infected cell protein 0 (bICP0) stimulates productive infection, in part by activating viral gene expression. The C(3)HC(4) zinc RING finger of bICP0 is crucial for activating viral transcription and productive infection. In this study, we used a bacterial artificial chromosome containing a wild-type (wt) virulent BHV-1 strain to generate a single amino acid mutation in the C(3)HC(4) zinc RING finger of bICP0. This virus (the 51g mutant) contains a cysteine-to-glycine mutation (51st amino acid) in the C(3)HC(4) zinc RING finger of bICP0. A plasmid expressing the 51g mutant protein did not transactivate viral promoter activity as efficiently as wt bICP0. The 51g mutant virus expressed higher levels of the bICP0 protein than did the 51g rescued virus (51gR) but yielded reduced virus titers following infection of permissive bovine cells. The 51g mutant virus, but not the 51gR virus, grew poorly in bovine cells pretreated with imiquimod to stimulate interferon production. During acute infection of calves, levels of infectious virus were 2 to 3 logs lower in ocular or nasal swabs with 51g than with 51gR. Calves latently infected with the 51g mutant did not reactivate from latency because virus shedding did not occur in ocular or nasal cavities. As expected, calves latently infected with 51gR reactivated from latency following dexamethasone treatment. These studies demonstrate that mutation of a single well-conserved cysteine residue in the C(3)HC(4) zinc RING finger of bICP0 has dramatic effects on the growth properties of BHV-1.

Abstract
The latency-related (LR) RNA encoded by bovine herpesvirus 1 (BHV-1) is abundantly expressed and alternatively spliced in trigeminal ganglia. A mutant BHV-1 strain that contains three stop codons at the beginning of LR open reading frame (ORF)-2 (LR mutant virus) does not express ORF-2 or an adjacent reading frame that lacks an initiating ATG (RF-C). Calves latently infected with wild-type (wt) BHV-1, but not with the LR mutant virus, reactivate from latency, indicating that proteins encoded by the LR gene regulate the latency-reactivation cycle. The LR gene also contains another large ORF (ORF-1) that is approximately 200 bp downstream of stop codons inserted at the N-terminus of ORF-2. To test whether the LR mutant virus can expresses ORF-1, the authors developed antiserum directed against ORF-1. The ORF-1 antiserum recognizes specific proteins in bovine cells productively infected with wt BHV-1. ORF-1 protein expression is reduced, but not blocked, when bovine cells are infected with the LR mutant virus. Confocal microscopy demonstrated ORF-1 is present in the cytoplasm and nucleus of productively infected cells, whereas RF-C or a fusion protein containing RF-C localizes to the cytoplasm. Trigeminal ganglia from calves latently infected with wt BHV-1 contain neurons specifically stained with the ORF-1 antiserum. These studies suggest ORF-1 expression may be important for the BHV-1 latency-reactivation cycle.

Abstract
Our objective was to determine the prevalence of serum antibodies to bovine herpesvirus-1 (BHV-1) and bovine viral diarrhea (BVD) virus in beef cattle in Uruguay. A random sample of 230 herds selected with probability proportional to population size based on the number of cattle was chosen from a list frame of all registered livestock farms as of June 1999. Sera from up to 10 heifers, cows and bulls (up to 30 sera total per herd) were collected on selected farms between March 2000 and March 2001 and evaluated by means of enzyme-linked immunosorbent assays (ELISAs). Overall, 6358 serum samples were evaluated. We also collected data on previous diagnosis of BHV-1 or BVD infections and on the use of vaccines against these agents. The estimated prevalence of exposure to BHV-1 and BVD at the herd level for the Uruguayan beef population was 99% and 100%, respectively. Approximately 37% of beef cattle in Uruguay have been exposed to BHV-1 and 69% to BVD virus. Only 3% of beef herds in Uruguay regularly (typically, annually) use vaccines against either of these agents.

Abstract
Four outbreaks of bovine respiratory disease (BRD) associated with bovine Coronavirus (BCoV) infection in Italian cattle herds were reported. In 3 outbreaks, BRD was observed only in 2–3-month-old feedlot calves, whereas in the remaining outbreak, lactating cows, heifers, and calves were simultaneously affected. By using reverse transcription polymerase chain reaction (RT-PCR), BCoV RNA was detected in all outbreaks without evidence of concurrent viral pathogens (i.e., bovine respiratory syncytial virus, bovine herpesvirus type 1, bovine viral diarrhea virus, bovine parainfluenza virus). Common bacteria of cattle were recovered only from 2 outbreaks of BRD: Staphylococcus spp. and Proteus mirabilis (outbreak 1) and Mannheimia haemolytica (outbreak 4). A recently established real-time RT-PCR assay showed that viral RNA loads in nasal secretions ranged between 3.10 × 10 2 and 7.50 × 10 7 RNA copies/μl of template. Bovine Coronavirus was isolated from respiratory specimens from all outbreaks except outbreak 1, in which real-time RT-PCR found very low viral titers in nasal swabs.

Abstract
The efficacy of a quadrivalent vaccine against viral bovine respiratory diseases (BRD) was assessed in four experimental studies. Calves between 2 and 9 months of age were allocated to one of two treatment groups (n=9-15) and then received either the vaccine or sterile saline in two doses approximately 3 weeks apart. Three to 5 weeks after the second injection, animals were challenged experimentally with one of the viruses, bovine herpes-virus-1 (BHV-1), parainfluenza type-3 virus (PI(3)V), bovine viral-diarrhoea virus type 1 (BVDV), or bovine respiratory syncytial virus (BRSV) and were then monitored for at least 2 weeks. The administration of the vaccine was associated with enhanced antibody response to all four viruses post-challenge, with the reduction of the amount or duration (or both) of virus shedding in the BHV-1, PI(3)V, BVDV and BRSV studies and with an improvement of some clinical signs in the BHV-1 (nasal discharge, and rectal temperature) and the PI(3)V studies (abnormal respiration, and depression).

Abstract
Viral infection dynamics and bovine respiratory disease (BRD) treatment rates were studied over six years at a Swedish bull testing station with an 'all in, all out' management system. In August of each of the years 1998-2003, between 149 and 185 4-8-month-old calves arrived at the station from 99 to 124 different beef-breeding herds, and remained until March the following year. Only calves that tested free from bovine viral diarrhoea virus (BVDV) were allowed to enter the station and original animal groups were kept isolated from new cattle in their original herds for three weeks before admission. Although neither prophylactic antibiotics, nor BRD vaccines were used, less than 0.7-13.2% (mean 5%) of the calves (n=970) required treatment for BRD during the first five weeks following entry. This was probably due, at least in part, to the season (the summer months) when the animals were commingled. In the six-month period August-February, 38% of the animals were treated one or more times for BRD and mortality was 0.7%. Hereford and Aberdeen Angus calves had significantly higher treatment rates than Charolais, Simmental and Blonde d'Aquitaine. Serological testing on samples obtained in August, November and January indicated that bovine parainfluenza virus 3 (PIV-3) infections occurred each year before November after entry. Bovine coronavirus (BCoV) infections also occurred every year, but in 3/6 years this was not until after November. Bovine respiratory syncytial virus (BRSV) infections occurred only every second year and were associated with a treatment peak and one death on one occasion (December). The herd remained BVDV free during the entire study period. The infection patterns for PIV-3 and BCoV indicated a high level of infectivity amongst bovine calves, whereas the incidence for BRSV was observed at a lower level. Although the rearing of the animals differed from conventional beef production, the study has shown that commingling animals from many sources is not necessarily associated with high morbidity within the first few weeks after arrival. By preventing BRD soon after commingling the prerequisites for protective vaccination at entry might be improved. Applied management routines are discussed.

Abstract
Pathogens causing bovine respiratory tract disease in Finland were investigated. Eighteen cattle herds with bovine respiratory disease were included. Five diseased calves from each farm were chosen for closer examination and tracheobronchial lavage. Blood samples were taken from the calves at the time of the investigation and from 86 calves 3–4 weeks later. In addition, 6–10 blood samples from animals of different ages were collected from each herd, resulting in 169 samples. Serum samples were tested for antibodies to bovine parainfluenza virus-3 (PIV-3), bovine respiratory syncytial virus (BRSV), bovine coronavirus (BCV), bovine adenovirus-3 (BAV-3) and bovine adenovirus-7 (BAV-7). About one third of the samples were also tested for antibodies to bovine virus diarrhoea virus (BVDV) with negative results. Bacteria were cultured from lavage fluid and in vitro susceptibility to selected antimicrobials was tested. According to serological findings, PIV-3, BAV-7, BAV-3, BCV and BRSV are common pathogens in Finnish cattle with respiratory problems. A titre rise especially for BAV-7 and BAV-3, the dual growth of Mycoplasma dispar and Pasteurella multocida, were typical findings in diseased calves. Pasteurella sp. strains showed no resistance to tested antimicrobials. Mycoplasma bovis and Mannheimia haemolytica were not found.

Prev Vet Med 2005; 66:63-77. [PMID: 15579335 DOI: 10.1016/j.prevetmed.2004.08.001] [Citation(s) in RCA: 30] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2003] [Revised: 08/11/2004] [Accepted: 08/18/2004] [Indexed: 11/23/2022]
Abstract
Several laboratory studies assessed the duration of immunity of a quadrivalent vaccine (Rispoval 4, Pfizer Animal Health) against bovine respiratory diseases (BRD) caused by bovine herpes-virus type-1 (BHV-1), parainfluenza type-3 virus (PI3V), bovine viral-diarrhoea virus type 1 (BVDV), or bovine respiratory syncytial virus (BRSV). Calves between 7 weeks and 6 months of age were allocated to treatment and then were injected with two doses of either the vaccine or the placebo 3 weeks apart. Six to 12 months after the second injection, animals were challenged with BHV-1 (n=16), PI3V (n=31), BVDV (n=16), or BRSV (n=20) and the course of viral infection was monitored by serological, haematological (in the BVDV study only), clinical, and virological means for > or =2 weeks. Infection induced mild clinical signs of respiratory disease and elevated rectal temperature in both vaccinated and control animals and was followed by a dramatic rise in neutralising antibodies in all treatment groups. Titres reached higher levels in vaccinated calves than in control calves after challenge with BHV-1, BVDV, or BRSV. On day 3 after PI3V challenge, virus shedding was reduced from 3.64 log10TCID50 in control animals to 2.59 log10TCID50 in vaccinated animals. On days 6 and 8 after BRSV challenge, there were fewer vaccinated animals (n=2/10 and 0/10, respectively) shedding the virus than control animals (n=8/10 and 3/10, respectively). Moreover, after challenge, the mean duration of virus shedding was reduced from 3.8 days in control animals to 1 day in vaccinated animals in the BVDV study and from 3.4 days in control animals to 1.2 days in vaccinated animals in the BRSV study. The duration of immunity of >or =6 months for PI3V, BHV-1 and BVDV, and 12 months for BRSV, after vaccination with Rispoval 4, was associated mainly with enhanced post-challenge antibody response to all four viruses and reduction of the amount or duration of virus shedding or both.

Abstract
Cytokines play a key role as regulators of the immune response. To elucidate whether the efficacy of a live virus vaccine can be improved by co-expression of cytokines, expression cassettes for bovine interleukins (boIL)-2, -4, -6, and -12 and bovine interferon-gamma (boIFN-gamma) were integrated into the glycoprotein E (gE)-locus of the bovine herpesvirus 1 (BHV-1) vaccine virus strain GK/D. Cell culture analyses demonstrated that expression of the cytokines did not impair the replication of the recombinant viruses. To test safety and efficacy, groups of 4-6 months old BHV-1 seronegative calves were vaccinated intranasally with the parental virus strain GK/D or the recombinants, and challenged intranasally 3 weeks later with virulent BHV-1. The animals were monitored for clinical signs, virus excretion and antibody status after vaccination and challenge. All vaccines were well tolerated and protected the immunised calves from clinical disease following challenge, and reduced duration and titres of challenge virus shedding. Calves inoculated with the boIL-6, boIL-12 and boIFN-gamma expressing recombinants showed a significant reduction in vaccine virus shedding but secreted more challenge virus than the other vaccinees. These findings indicate that expression of these cytokines mediates a better control of the vaccine virus replication which, however, interferes with the immunogenicity of the vaccine. In summary, all recombinant viruses were safe and effective, but protection afforded by the recombinants was not improved as compared to vaccination with the parental virus strain GK/D.

Abstract
Bovine Respiratory Disease (BRD) results from a complex, multifactorial interaction of stressors, animal susceptibility, and respiratory pathogens. The infectious agents associated with BRD are ubiquitous among cattle populations. Typically, one or a combination of stressors are necessary to initiate BRD. Prevention of BRD should, therefore, address management procedures to minimise stressors. Administration of vaccines against BRD agents may help reduce the incidence of BRD but is unlikely to eliminate the condition. The effectiveness of antimicrobials in the treatment of BRD depends primarily on early recognition and treatment. The use of antioxidant vitamins, minerals or other agents in the prevention and treatment of BRD warrants further research.

Abstract
The bovine respiratory disease complex continues to be an economically important syndrome in an era when immunologic control is likely to become increasingly important. Recent studies have yielded a better understanding of the interaction, at the molecular level, of various pathogens with the bovine immune system. Improved challenge models for important viral pathogens such as bovine viral diarrhea virus and bovine respiratory syncytial virus have provided evidence of the efficacy of immune responses stimulated by vaccination. This article highlights recent advances in understanding of the role of the immune response in the pathogenesis and prophylaxis of bovine respiratory disease complex.

Abstract
The Kansas/15626/84 (Ka) and Shipping Fever (SF) strains of bovine parainfluenza virus type 3 (BPIV3) replicate less efficiently than human PIV3 (HPIV3) in the upper and lower respiratory tract of rhesus monkeys, and BPIV3 Ka is also highly attenuated in humans and is in clinical trials as a candidate vaccine against HPIV3. To initiate an investigation of the genetic basis of the observed attenuation phenotype of BPIV3 in primates, the complete genomic sequences of Ka and SF genomes were determined and compared to those of BPIV3 strain 910N and two HPIV3 strains, JS and Wash/47885/57. There is a high degree of identity between the five PIV3 viruses in their 55 nucleotide (nt) leader (83.6%) and 44 nt trailer (93.2%) sequences. The five viruses display amino acid sequence identity ranging from 58.6% for the phosphoprotein to 89.7% for the matrix protein. Interestingly, the majority of amino acid residues found to be variable at a given position in a five-way protein alignment are nonetheless identical within the viruses of either host species (BPIV3 or HPIV3). These host-specific residues might be products of distinct selective pressures on BPIV3 and HPIV3 during evolution in their respective hosts. These host-specific sequences likely include ones which are responsible for the host range differences, such as the efficient growth of BPIV3 in bovines compared to its restricted growth in primates. It should now be possible using the techniques of reverse genetics to import sequences from BPIV3 into HPIV3 and identify those nt or protein sequences which attenuate HPIV3 for primates. This information should be useful in understanding virus-host interactions and in the development of vaccines to protect against HPIV3-induced disease.

Abstract
Four groups of calves were vaccinated with a glycoprotein E-negative vaccine for infectious bovine rhinotracheitis. Two groups of calves were vaccinated intramuscularly and challenged with a wild-type virus 14 and seven days after being vaccinated. The other two groups were vaccinated intranasally and similarly challenged after four and three days; an unvaccinated control group was also challenged. All four vaccination schedules reduced the incidence of clinical signs and the excretion of wild-type virus, and these reductions occurred as early as three days after the intranasal vaccination even in the absence of neutralising antibodies. Because of its marker characteristics, vaccination with this vaccine would not interfere with the detection of infected cattle during an outbreak, and it should therefore provide a useful tool for emergency vaccination campaigns.

Abstract
Bovine respiratory disease (BRD) remains a significant cost to both the beef and dairy industries. In the United States, an estimated 640 million dollars is lost annually due to BRD. Losses are largely a result of pneumonic pasteurellosis ("shipping fever"), enzootic pneumonia of calves, and atypical interstitial pneumonia. In Canada, over 80% of the biologics licensed for use in cattle are against agents associated with BRD. The objectives of this paper were (a) to summarize information available concerning commercial vaccines currently used in Canada for protection against BRD, and (b) to provide an easily accessible resource for veterinary practitioners and researchers. Information from the most recent Compendium of Veterinary Products has been tabulated for each vaccine by trade name, according to vaccine type, and the pathogens against which they are designed to protect. Additional information from published articles (peer-reviewed and other) has been provided and referenced.

Abstract
We developed a monoclonal antibody-based, antigen capture sandwich enzyme-linked immunosorbent assay (ELISA) for bovine coronavirus. We compared the ELISA with electron microscopy and the hemagglutination test and found a close correlation between them. The sensitivity of the ELISA was 10(4) bovine coronavirus particles per ml of 10% fecal suspension. Compared with electron microscopy, bovine coronavirus ELISA had 96% specificity.
