Prevalence of antibodies to bovine viral diarrhoea virus in bulk tank milk and associated risk factors in Scottish dairy herds.

Bulk tank milk samples were collected from 374 dairy farms in Scotland in 2007/2008 along with questionnaire data relating to the management of the farm. Milk samples were tested for antibodies to bovine viral diarrhoea virus (BVDV) using a commercially available (Svanova) kit and percentage positivity scores calculated according to the manufacturer's guidelines. There were 220 farms that did not routinely vaccinate for bovine viral diarrhoea (BVD), and these were distributed according to the Swedish BVD eradication classes as 12.

Complete genomic sequence of a border disease virus isolated from Pyrenean chamois.

This report describes the full-length genome sequence of the pestivirus strain H2121 which was recently isolated from Pyrenean chamois and typed as Border disease virus (BDV) genotype 4. Comparison with full-length genomic sequences of the approved pestivirus species Bovine viral diarrhea virus-1 (BVDV-1), BVDV-2, BDV, and Classical swine fever virus, the tentative species represented by strain Giraffe-1, as well as the atypical pestivirus strain Th/04_KhonKaen confirmed that the chamois pestivirus strain is most similar to BDV. The viral genome of H2121 is 12,305 nucleotides long and contains one large open reading frame.

Epidemiology of squirrelpox virus in grey squirrels in the UK.

The dramatic decline of the native red squirrel in the UK has been attributed to both direct and disease-mediated competition with the grey squirrel where the competitor acts as a reservoir host of squirrelpox virus (SQPV). SQPV is threatening red squirrel conservation efforts, yet little is known about its epidemiology. We analysed seroprevalence of antibody against SQPV in grey squirrels from northern England and the Scottish Borders in relation to season, weather, sex, and body weight using Generalized Linear Models in conjunction with Structural Equation Modelling.

Poxviral disease in red squirrels Sciurus vulgaris in the UK: spatial and temporal trends of an emerging threat.

The squirrel poxvirus (SQPV) is the probable mediator of apparent competition between the introduced invading gray squirrel (Sciurus carolinensis) and the red squirrel (Sciurus vulgaris) in the UK, and modeling studies have shown that this viral disease has had a significant impact on the decline of the red squirrel in the UK. However, given our limited understanding of the epidemiology of the disease, and more generally the effects of invasive species on parasite ecology, there is a need to investigate the transmission dynamics and the relative pathogenicity of the virus between species. We aimed to increase our knowledge of these processes through an empirical study in which we: (i) used pathological signs and transmission electron microscopy (TEM) to diagnose SQPV disease in red squirrels found dead during scanning surveillance between 1993 and 2005; (ii) detected antibody to SQPV using an enzyme-linked immunosorbent assay (ELISA) in the same animals; and (iii) mapped cases of the disease, and the gray squirrel distribution, using a geographical information system.

Epidemics of squirrelpox virus disease in red squirrels ( Sciurus vulgaris): temporal and serological findings.

Squirrelpox virus (SQPV) causes a fatal disease in free-living red squirrels (Sciurus vulgaris) which has contributed to their decline in the United Kingdom. Given the difficulty of carrying out and funding experimental investigations on free-living wild mammals, data collected from closely monitored natural outbreaks of disease is crucial to our understanding of disease epidemiology. A conservation programme was initiated in the 1990s to bolster the population of red squirrels in the coniferous woodland of Thetford Chase, East Anglia.

Current mentorship schemes might be doing our students a disservice.

This paper reports on a multi-professional research study, which aimed to explore mentee and mentor perceptions of the mentorship role within nursing, midwifery and medicine. The specific focus of the study was on the conceptualisation of mentoring within the health setting, the factors that influence the mentor-mentee relationship in a positive/negative way, what the professional and personal needs of the mentees are and what are the training and development needs of mentors. This paper will focus on the nursing responses from both questionnaire and interview data highlighted by the responses from the other healthcare professions.

Development of a real time reverse transcriptase polymerase chain reaction for the detection of bovine respiratory syncytial virus in clinical samples and its comparison with immunohistochemistry and immunofluorescence antibody testing.

Bovine respiratory syncytial virus is an agent involved in calf pneumonia complex, a disease of significant economic importance. Accurate diagnosis of the agents involved on farm premises is important when formulating disease control measures, including vaccination. We have developed a real time reverse transcriptase polymerase chain reaction (rtRT-PCR) and compared it with the diagnostic tests currently available in the United Kingdom: immunohistochemistry (IHC) and immunofluorescence antibody test (IFAT).

Assessor or mentor? Role confusion in professional education.

This paper reports on research conducted as part of a multi-professional study involving nursing, medicine and midwifery, which aimed to investigate both mentee and mentor perceptions of the mentorship role and the context within which it is conducted. It is well recognised that mentorship plays a vital part in the support and training of healthcare professionals. Documentation published by regulatory bodies regarding the mentorship role and changes in it's implementation in practice has resulted in confusion among practitioners.

Antiviral activity of HPMPC (cidofovir) against orf virus infected lambs.

(S)-1-[3-hydroxy-2-(phosphonomethoxy)propyl]cytosine [corrected] (HPMPC, cidofovir, CDV, Vistide) is an acyclic nucleoside analogue with a potent and selective activity against a broad spectrum of DNA viruses including the poxviruses. In this study we present the results of different treatment regimens in lambs experimentally infected with orf virus with different cidofovir formulations prepared in Beeler basis and Unguentum M. Our results show that choice of excipient, concentration of codofovir [corrected] and treatment regimen were all important to the clinical outcome of the therapy.

Genomic characterization of a novel poxvirus contributing to the decline of the red squirrel (Sciurus vulgaris) in the UK.

The genome of a virulent squirrelpox virus (SQPV) isolate was characterized in order to determine its relationship with other poxviruses. Restriction enzyme analysis suggested a genome length of approximately 158 kb, whilst sequence analysis of the two ends of the genome indicated a G + C composition of approximately 66 %. Two contiguous stretches of 23 and 37 kb at the left-hand and right-hand ends of the genome, respectively, were sequenced allowing the identification of at least 59 genes contained therein.

Pestiviruses in wild animals.

Pestiviruses are not strictly host-species specific and can infect not only domestic but also wild animals. The most important pestivirus, CSFV, infects domestic pigs and wild boars, which may cause a major problem for successful CSFV eradication programmes. Mainly BVDV specific antibodies have been reported in captive and free-living animals.

Detection of Louping ill virus in clinical specimens from mammals and birds using TaqMan RT-PCR.

The identification of Louping ill virus (LIV) in clinical specimens has been routinely achieved by virus isolation using susceptible pig kidney cells and subsequent serological analysis. While this method is sensitive and detects infectious virus, it is relatively labour intensive and time-consuming. In view of the veterinary and potential medical importance of LIV, a rapid and precise detection method for routine use that employs the TaqMan reverse transcription polymerase chain reaction (RT-PCR) has been developed to detect LIV RNA extracted from field samples.

Development of an enzyme-linked immunosorbent assay for the detection of antibodies against malignant catarrhal fever viruses in cattle serum.

Malignant catarrhal fever (MCF) is a sporadic but fatal lymphoproliferative viral disease of cattle, deer and other ruminants. The causative agents are highly-cell-associated herpesviruses of the subfamily gammaherpesvirinae. In this study, an ELISA (WC11-ELISA) was developed to detect antibody to malignant catarrhal fever virus (MCFV) in cattle serum and compared to the commercially produced competitive-inhibition ELISA (CI-ELISA).

Development of a real time RT-PCR to detect and type ovine pestiviruses.

A real time one-step RT-PCR was designed to detect and type border disease virus (BDV), bovine viral diarrhea virus (BVDV) type 1 and BVDV type 2 in ovine samples. The real time RT-PCR was shown to behave in a linear manner and had limits of detection of 100-1000 copies of viral RNA as judged by in vitro transcribed RNA. The real time RT-PCR was validated on 50 clinical samples from UK flocks and was more sensitive than a virus isolation and a classical nested RT-PCR (nRT-PCR).

Disease threats posed by alien species: the role of a poxvirus in the decline of the native red squirrel in Britain.

Red squirrels are declining in the United Kingdom. Competition from, and squirrel poxvirus (SQPV) disease carried by, grey squirrels are assumed to be determining the decline. We analyse the incidence of disease and changes in distribution of the two species in Cumbria, from 1993 to 2003 and compare these to the predictions of an individual-based (IB) spatially explicit disease model simulating the dynamics of both squirrel species and SQPV in the landscape.
