Nomenclature updates resulting from the evolution of avian influenza A(H5) virus clades 2.1.3.2a, 2.2.1, and 2.3.4 during 2013-2014.

AIM: The A/goose/Guangdong/1/96-like hemagglutinin (HA) genes of highly pathogenic avian influenza (HPAI) A(H5) viruses have continued to rapidly evolve since the most recent update to the H5 clade nomenclature by the WHO/OIE/FAO H5N1 Evolution Working Group. New clades diverging beyond established boundaries need to be identified and designated accordingly. METHOD: Hemagglutinin sequences deposited in publicly accessible databases up to December 31, 2014, were analyzed by phylogenetic and average pairwise distance methods to identify new clades that merit nomenclature changes. RESULTS: Three new clade designations were recommended based on division of clade 2·1·3·2a (Indonesia), 2·2·1 (Egypt), and 2·3·4 (widespread detection in Asia, Europe, and North America) that includes newly emergent HPAI virus subtypes H5N2, H5N3, H5N5, H5N6, and H5N8. CONCLUSION: Continued global surveillance for HPAI A(H5) viruses in all host species and timely reporting of sequence data will be critical to quickly identify new clades and assess their potential impact on human and animal health.The Melbourne WHO Collaborating Centre for Reference and Research on Influenza is supported by the Australian Government Department of Health.This is the final version of the article.

Global mapping of highly pathogenic avian influenza H5N1 and H5Nx clade 2.3.4.4 viruses with spatial cross-validation.

Global disease suitability models are essential tools to inform surveillance systems and enable early detection. We present the first global suitability model of highly pathogenic avian influenza (HPAI) H5N1 and demonstrate that reliable predictions can be obtained at global scale. Best predictions are obtained using spatial predictor variables describing host distributions, rather than land use or eco-climatic spatial predictor variables, with a strong association with domestic duck and extensively raised chicken densities. Our results also support a more systematic use of spatial cross-validation in large-scale disease suitability modelling compared to standard random cross-validation that can lead to unreliable measure of extrapolation accuracy. A global suitability model of the H5 clade 2.3.4.4 viruses, a group of viruses that recently spread extensively in Asia and the US, shows in comparison a lower spatial extrapolation capacity than the HPAI H5N1 models, with a stronger association with intensively raised chicken densities and anthropogenic factors

Evaluating the need for an animal welfare assurance programme in South Tyrolean dairy farming

Animal welfare assurance is of great importance as dairy farming is recently under increasing pressure to meet societal and commercial expectations. Therefore, this study aims to determine the current welfare situation of dairy cattle housed in tie-stalls and free stalls in South Tyrol (Eastern Italian Alps) in order to evaluate the need for establishment of an animal welfare assurance programme. For reasons of research economy, a protocol was used for data collection that would also be applicable for practical use in an animal welfare assurance scheme. Analyses of resource-based and animal-based indicators recorded in 204 farms in North and South Tyrol (1891 dairy cows) reveal some important animal welfare problems mainly related to the provision of resources and the prevalence of skin alterations especially in tie-stall barns, which are still widely spread in mountain areas. Hence, the implementation of an animal welfare assurance scheme is urgently needed to reflect public concerns through regular and standardised monitoring of welfare indicators and continuous encouragement of improvements in dairy cattle welfare towards predefined targets. Concerning tie-stalls, interventions in stall design as well as the selective use of local breeds best adapted to the mountainous conditions appear to be appropriate measures to optimise dairy cattle health and welfare. These findings substantiate the high value of the data that would be collected as part of the assurance programme to gain insights, which could be used in preventive and corrective health plans to improve welfare-friendliness in dairy farming of South Tyrol

Serosurvey of pandemic H1N1 influenza A virus in dogs in Andalusia (southern Spain)

In April 2009, a new influenza A virus (IAV) subtype (A(H1N1)pdm09) spread worldwide and triggered the first human influenza pandemic of the 21st century. Since then, exposure to the pandemic H1N1 IAV has been confirmed in different animal species. Serological evidence and clinical infection with A(H1N1)pdm09 have been reported in canines, but the information available about the role of dogs in the epidemiology of this IAV subtype is still very limited in Europe. A cross‐sectional study was carried out to determine the seroprevalence of A(H1N1)pdm09 in dogs in southern Spain, a region with endemic seasonal circulation in human. Sera from 750 companion dogs were collected during the period 2013–2016. Antibodies against pandemic H1N1 IAV were analysed using the haemagglutination inhibition test. Positive samples were also tested by single radial haemolysis assay. Seropositivity was only confirmed by both methods in one (0.13%; 95% CI: 0.00–0.38) adult animal sampled in 2013. To the best of the authors’ knowledge, this is the first report of A(H1N1)pdm09 exposure in dogs in Spain. The low seroprevalence obtained indicates a limited exposure history to A(H1N1)pdm09 IAV in dogs in this country and suggests a low risk of transmission of this zoonotic IAV subtype between humans and dogs

Welfare assessment in broiler farms : transect walks versus individual scoring

Absolute yields of negative ions and secondary electrons resulting from positive ions impacting a stainless steel surface have been determined as a function of the impact energy. The surface conditions range from those commonly found in situ for discharge electrodes to a surface free of any adsorbate. The implications of these findings to discharge modeling are discussed

FMD vaccine matching: Inter laboratory study for improved understanding of r1 values

Foot-and-mouth disease virus (FMDV) is a highly variable RNA virus existing as seven different serotypes. The antigenic variability between and within serotypes can limit the cross-reactivity and therefore the in vivo cross-protection of vaccines. Selection of appropriate vaccine strains is crucial in the control of FMD. Determination of indirect relationships (r1-value) between potential vaccine strains and field strains based on antibody responses against both are routinely used for vaccine matching purposes. Aiming at the investigation of the repeatability, reproducibility and comparability of r1-value determination within and between laboratories and serological tests, a small scale vaccine matching ring test for FMDV serotype A was organized. Well-characterized serum pools from cattle vaccinated with a monovalent A24/Cruzeiro/Brazil/55 (A24) FMD vaccine with known in vivo protection status (homologous and heterologous) were distributed to four laboratories to determine r1-values for the heterologous FMD strains A81/Argentina/87, A/Argentina/2000 and A/Argentina/2001 using the virus neutralization tests (VNT) and liquid phase blocking ELISA (LPBE). Within laboratories, the repeatability of r1-value determination was high for both antibody assays. VNT resulted in reproducible and comparable r1-values between laboratories, indicative of a lack of antigenic relatedness between the A24 strain and the heterologous strains tested in this work, thus corresponding to some of the in vivo findings with these strains. Using LPBE, similar trends in r1-values were observed in all laboratories, but the overall reproducibility was lower than with VNT. Inconsistencies between laboratories may at least in part be attributed to differences in LPBE protocols as well as the in preexisting information generated in each laboratory (such as antibody titer-protection correlation curves). To gain more insight in the LPBE-derived r1-values standard bovine control sera were included in the antibody assays performed in each laboratory and a standardization exercise was performed.Fil: Willems, Tom.

RSPCA and the criminology of social control

This paper contributes to a rethinking of animal abuse control and animal welfare protection in criminology, specifically, and in the social sciences more broadly. We do this, first, through a broad mapping of the institutional control complex around animal abuse in contemporary Britain. Second, we focus on the institutional strategies and practices, past and present, of the main agency of animal protection, and the policing thereof, in this society, namely the Royal Society for the Prevention of Cruelty to Animals (RSPCA). In looking back to this charity’s growth since the first decades of the nineteenth century at the time of the birth of modern industrial capitalism and also to its current rationale and practices as a late-modern, corporate organisation, we explore the seeming paradox of a private body taking a lead on the regulation and prosecution of illegalities associated with animal-human relationships. Finally, the ideology and strategy of the RSPCA are explored in the context of the often visceral and culturally influential ‘morality war’ associated with proponents, respectively, of animal rights (‘abolition’) and ‘anthropic’ welfare proponents (‘regulation’ and ‘protection’)
