An economic assessment of pseudorabies (Aujeszky' disease) elimination on hog farms in China.

Prev Vet Med 2019 Feb 13;163:24-30. Epub 2018 Dec 13.

Business Economics Group, Wageningen University and Research, Hollandseweg 1, 6706 KN, Wageningen, the Netherlands. Electronic address:

Hog pseudorabies (Aujeszky's disease) can incur serious losses for farm owners and even the entire hog industry by causing infertility, abortion, and stillbirth among sows, as well as diarrhoea, respiratory failure, and death among piglets. Pseudorabies virus could be prevented, controlled, and eliminated by clean-up at both farm and regional levels through a strict procedure of vaccination, quarantine, diagnosis, elimination of positive animals, and healthy animals nurturing. Using data from 63 large-scale hog farms from nine provinces (municipalities, autonomous regions) of China, we evaluated the economic consequences of hog pseudorabies clean-up in China's hog farms based on a partial budgeting method.

Department of Biology, Colorado State University, 1878 Campus Delivery, Fort Collins, CO 80523, USA; Graduate Degree Program in Ecology, Colorado State University, 1021 Campus Delivery, Fort Collins, CO 80523, USA.

Mathematical models are key tools for the development of surveillance, preparedness and response plans for the potential events of emerging and introduced foreign animal diseases. Creating these types of plans requires data; when data are incomplete, mathematical models can help fill in missing information, provided they are informed by the data that are available. In the United States, the most complete national-scale data available on cattle shipments are based on Interstate Certificates of Veterinary Inspection, which track the shipment of cattle between states; data on intrastate cattle shipments are lacking.

Prev Vet Med 2019 Jan 2;162:46-55. Epub 2018 Nov 2.

Federal Institute for Risk Assessment, Department of Exposure, Berlin and University of Veterinary Medicine Hannover, Foundation, Germany. Electronic address:

The quality of diagnostic accuracy studies (DAS) for infectious diseases of animals has improved over the last 20 years because of international educational efforts, use of design and reporting standards to guide researchers and test developers, and acceptance of the use of latent class models to account for imperfect reference tests. In this review, we focus on measurement of diagnostic sensitivity and specificity as a measure of clinical validity, describe the leadership role of the World Organisation of Animal Health (OIE) in setting standards for test validation in the context of fitness-for-purpose, and describe how design and reporting quality have facilitated the increased use of systematic reviews and meta-analysis of DAS. Ongoing challenges for design, conduct, analysis and reporting of DAS are identified; and we make recommendations for improvements in these areas for OIE-listed and non-listed infectious diseases.

Department of Population Medicine, Ontario Veterinary College, University of Guelph, Canada; Department of Large Animal Clinical Sciences, Western College of Veterinary Medicine University of Saskatchewan, Canada. Electronic address:

The overall objective of this study was to describe the contact structure and animal movement patterns of porcine epidemic diarrhea (PED) case herds and matched control herds during the initial incursion of PEDV in Canada, and to evaluate possible mechanisms of spread during this period. Possible mechanisms of spread included transmission through a common-source, herd-to-herd transmission, and transmission due to low biosecurity. Three hypotheses were evaluated by assessing: 1) whether feed supplier, semen supplier and/or animal transportation company networks contained a higher proportion of case herds compared to randomly permuted networks, 2) whether the proportion of case herds in the giant weak component differed from randomly permuted networks, and 3) whether external herd biosecurity, defined as the number of mean contacts with other herds in a one-mode network, was different between case and control herds.

Biosecurity system reforms and the development of a risk-based surveillance and pathway analysis system for ornamental fish imported into Australia.

Prev Vet Med 2018 Nov 13. Epub 2018 Nov 13.

Centre of Excellence for Biosecurity Risk Analysis (CEBRA), The University of Melbourne, Australia.

The ornamental fish trade in Australia has an estimated value of AUD$350 million and involves importation of up to 20 million fish from 26 approved countries each year. Critical reviews indicated that the biosecurity system did not fully manage the risks associated with fish that were sub-clinically infected with diseases such as megalocytiviruses, or the threats posed by emerging diseases. Subsequent reforms have placed a greater emphasis on managing biosecurity risks off-shore at the source, coupled with an on-arrival surveillance system to assess compliance with biosecurity regulation.

Inferences about the transmission of lumpy skin disease virus between herds from outbreaks in Albania in 2016.

Prev Vet Med 2018 Dec 17. Epub 2018 Dec 17.

European Food Safety Authority, Via Carlo Magno 1A, 43126 Parma, Italy.

Lumpy skin disease has recently emerged as a major threat to cattle populations outside of Africa, where it is endemic. In 2015 the first ever European outbreaks occurred in Greece, which were followed by spread across much of the Balkans in 2016. Here we use a simple mathematical model for the transmission of lumpy skin disease virus (LSDV) between herds to explore factors influencing its spread by fitting it to data on outbreaks in Albania in 2016.

Field observations and experiences gained from the implementation of control measures against lumpy skin disease in South-East Europe between 2015 and 2017.

Prev Vet Med 2018 Dec 13. Epub 2018 Dec 13.

European Food Safety Authority, Parma, Italy.

The first epidemics of lumpy skin disease (LSD) reported in Europe in 2015 severely affected the cattle farming sector in several Balkan countries. After the first incursion into Greece in 2015, the disease quickly spread across the Balkan region with over 7000 outbreaks reported by the end of 2016. Thanks to a coordinated regional control and eradication policy, the spread of the disease was halted by the end of 2017. Read More

Neethling vaccine proved highly effective in controlling lumpy skin disease epidemics in the Balkans.

Prev Vet Med 2018 Dec 5. Epub 2018 Dec 5.

European Food Safety Authority, Via Carlo Magno 1A, 43126 Parma, Italy.

Despite the wide use of the live attenuated Neethling lumpy skin disease (LSD) vaccine, only limited data existed on its efficacy and effectiveness prior to the large LSD epidemic in the Balkans, which took place during 2016-2017. In addition, analysis of risk factors for the disease was hardly performed with proper control for vaccination effects and potential differences in exposure to the virus. Data from the LSD epidemics in six Balkan countries (Bulgaria, Greece, Serbia, Montenegro, Former Yugoslav Republic of Macedonia (FYROM) and Albania) affected during 2016 were analyzed to determine vaccine effectiveness (VE) and risk factors for LSD infection at the farm level.

The concept of One Health (OH) promotes the decompartmentalisation of human, animal, and ecosystem health for the more efficient and sustainable governance of complex health issues. This means that traditional boundaries between disciplines and sectors must be transgressed and that all relevant stakeholders must be involved in the definition and management of health problems. International efforts have been made to strengthen collaboration across sectors and disciplines and OH surveillance is strongly encouraged at global, national and local-level to efficiently manage hazards involving humans, animals and ecosystems.

Bayesian estimation of sensitivity and specificity of culture- and PCR-based methods for the detection of six major non-O157 Escherichia coli serogroups in cattle feces.

Prev Vet Med 2018 Dec 28;161:90-99. Epub 2018 Oct 28.

Department of Diagnostic Medicine/Pathobiology, Kansas State University, Manhattan, KS, 66502, United States.

Non-O157 Shiga toxin-producing Escherichia coli (non-O157 STEC, O26, O45, O103, O111, O121, and O145) are foodborne pathogens of public health importance. Culture and PCR-based methods have been developed for the detection of these serogroups in cattle feces. The objectives of this study were to evaluate diagnostic sensitivity and specificity of PCR- and culture-based methods for the detection of the six non-O157 serogroups, and to estimate their true prevalence in cattle feces, using a Bayesian latent class modeling approach that accounts for conditional dependence among the three methods.

Department of Animal Nutrition and Production, School of Veterinary Medicine and Animal Science, University of São Paulo, Pirassununga, Brazil. Electronic address:

The objectives of this study were to characterize the pathogen frequency and severity of clinical mastitis (CM) in 20 dairy herds of southeastern Brazil; and to determine the incidence rate of clinical mastitis (IRCM; overall and based on specific-pathogen groups) based on quarter time at risk and its association with risk factors at the herd-level. Data were recorded in each herd for a period of 8 to 15 months. The association between herd-level risk factors and IRCM were determined by two groups of mixed regression models: one based on the overall IRCM, and five based on the following specific-pathogen groups: contagious, other Gram-positive, Gram-negative, other, and negative culture.

EpiCentre, School of Veterinary Science, Massey University, Private Bag 11-222, Palmerston North, New Zealand.

Understanding risk factors for bovine viral diarrhoea (BVD) transmission is important for planning national disease control programmes. However, traditional statistical approaches may miss important features of BVD epidemiology due to the highly correlated nature of many farm-level risk factors. In this cross-sectional study, we used data collected from 304 cattle herds in New Zealand during 2015/2016 to compare the results from multivariable logistic regression with Bayesian network (BN) analysis.

Breed-to-wean pig farms play an important role in spreading influenza A virus (IAV) because suckling piglets maintain, diversify and transmit IAV at weaning to other farms. Understanding the nature and extent of which farm factors drive IAV infection in piglets is a prerequisite to reduce the burden of influenza in swine. We evaluated the association between IAV infection in piglets at weaning and farm factors including farm features, herd management practices and gilt- and piglet-specific management procedures performed at the farm.
