A simple method to estimate the size of the vaccine bank needed to control an epidemic of an exotic infectious disease in case of introduction into a country is presented. The method was applied to the case of a Lumpy Skin disease (LSD) epidemic in France. The size of the stock of vaccines needed was calculated based on a series of simple equations that use some trigonometric functions and take into account the spread of the disease, the time required to obtain good vaccination coverage and the cattle density in the affected region. Assuming a 7-weeks period to vaccinate all the animals and a spread of the disease of 7.3 km/week, the vaccination of 740 716 cattle would be enough to control an epidemic of LSD in France in 90% of the simulations (608 196 cattle would cover 75% of the simulations). The results of this simple method were then validated using a dynamic simulation model, which served as reference for the calculation of the vaccine stock required. The differences between both models in different scenarios, related with the time needed to vaccinate the animals, ranged from 7% to 10.5% more vaccines using the simple method to cover 90% of the simulations, and from 9.0% to 13.8% for 75% of the simulations. The model is easy to use and may be adapted for the control of different diseases in different countries, just by using some simple formulas and few input data. [less ▲]

Canine idiopathic pulmonary fibrosis (CIPF) is a progressive parenchymal lung disease of unknown origin and poorly understood pathophysiology that mainly occurs in old West Highland white terriers (WHWTs). Not all dogs from the WHWT breed develop CIPF, which suggests the involvement of triggering factors in the onset and/or progression of the disease. To assess potential triggers, an online questionnaire–based survey was submitted to WHWTs owners. The questionnaire was accessible during a 3-month period in 3 different languages (English, French, and Dutch) and was distributed to WHWTs owners and breeders through social medial and emails. Questions were divided into sections regarding owner, dog (clinical and diagnostic data for CIPF), environment (house and surroundings, compost, ventilation, air conditioning, humidification, asbestosis, smoking, and household maintenance), grooming, and veterinary care (vaccination, deworming, and comorbidities). Completed questionnaires were received from 458 WHWTs owners from various countries including principally USA (n=193), Australia (n=62), France (n=56), UK (n=39), and Belgium (n=30). Thirty-eight questionnaires were discarded due to lack of essential data resulting in a total amount of 420 exploitable responses, 138 of which concerning a CIPF affected WHWT. Median age reported at CIPF diagnosis was 11.5 years (range 2– 6.8). Inspiratory crackles were noticed in 82.3% of dogs. Seventy-three out of 138 (52.9%) CIPF WHWTs were dead at the time of questionnaire completion. The overall survival time after diagnosis was 1.4 years (0–8.5). Cause of death was CIPF-related in 76.7% of cases. In order to assess potential triggers associated with CIPF, each CIPF dog was matched to one unaffected WHWT by age. Univariate logistic regression analysis was used for group comparison (CIPF vs. CTRL). Statistical significance was set at a P-value ≤ 0.05. Parameters significantly associated with CIPF included genetic relationship with another dog affected with CIPF (P=0.025), living in an old house (P=0.012), absence of a ventilation system (P<0.0001), and frequent grooming in dedicated facilities (P=0.001). CIPF dogs were at increased risk of cardiac disease (P=0.001), most likely due to the development of secondary pulmonary hypertension, and at decreased risk of endocrine disease (P=0.01) compared with CTRL. The preliminary results of this survey suggest an association between CIPF, genetic background and environmental factors such as old nonventilated houses or grooming habits. Further analysis of the results of the questionnaire are ongoing [less ▲]

Feed sustainability is one of the biggest challenges for the next few years. Solutions have to be found that take feed quality and safety into account. Animal by-products are one valuable source of proteins. However, since the bovine spongiform encephalopathy (BSE) crisis, their use has been strictly regulated. The objective of this study was to propose a routine, sensitive and specific method using ultra-high performance liquid chromatography coupled to tandem mass spectrometry for the detection of blood-derived products and milk powder in feed. Contaminated aquafeeds were analysed in order to evaluate the sensitivity and specificity of the method. This new method meets both selectivity and sensitivity (0.1% (w/w)) requirements imposed by the European Commission for animal proteins detection methods. It offers an innovative and complementary solution for the simultaneously identification of authorised and unauthorised animal by-products such as processed animal proteins (PAPs). [less ▲]

Foot-and-mouth disease (FMD) is endemic in Niger, with outbreaks occurring every year. Recently, there was an increasing interest from veterinary authorities to implement preventive and control measures against FMD. However, for an efficient control, improving the current knowledge on the disease dynamics and factors related to FMD occurrence is a prerequisite. The objective of this study was therefore to obtain insights into the incidence and the spatio-temporal patterns of transmission of FMD outbreaks in Niger based on the retrospective analysis of 9-year outbreak data. A regression tree analysis model was used to identify statistically significant predictors associated with FMD incidence, including the period (year and month), the location (region), the animal-contact density and the animal-contact frequency. This study provided also a first report on economic losses associated with FMD. From 2007 to 2015, 791 clinical FMD outbreaks were reported from the eight regions of Niger, with the number of outbreaks per region ranging from 5 to 309. The statistical analysis revealed that three regions (Dosso, Tillabery and Zinder), the months (September, corresponding to the end of rainy season, to December and January, i.e., during the dry and cold season), the years (2007 and 2015) and the density of contact were the main predictors of FMD occurrence. The quantitative assessment of the economic impacts showed that the average total cost of FMD at outbreak level was 499 euros, while the average price for FMD vaccination of one outbreak was estimated to be more than 314 euros. Despite some limitations of the clinical data used, this study will guide further research into the epidemiology of FMD in Niger and will promote a better understanding of the disease as well as an efficient control and prevention of FMD.

We report the detection of Moku virus in honey bees (Apis mellifera) collected in 2017 from hives with a history of attacks by invasive Asian hornets (Vespa velutina nigrithorax) in Belgium. End 2016, Moku virus was reported in Asian hornets from the same area. In addition, the Moku virus was already present in historical samples of bees collected in 2013, that is, 2 years after the official first detection of Asian hornets in the same area of Belgium. This study suggests a spread of Moku virus to honey bees with possible consequences. [less ▲]

BACKGROUND: The lumpy skin disease virus (LSDV) is a dsDNA virus belonging to the Poxviridae family and the Capripoxvirus genus. Lumpy skin diseases (LSD) is a highly contagious transboundary disease in cattle producing major economic losses. In 2014, the disease was first reported in the European Union (in Cyprus); it was then reported in 2015 (in Greece) and has spread through different Balkan countries in 2016. Indirect vector transmission is predominant at small distances, but transmission between distant herds and between countries usually occurs through movements of infected cattle or through vectors found mainly in animal trucks. METHODS AND PRINCIPAL FINDINGS: In order to estimate the threat for France due to the introduction of vectors found in animal trucks (cattle or horses) from at-risk countries (Balkans and neighbours), a quantitative import risk analysis (QIRA) model was developed according to the international standard. Using stochastic QIRA modelling and combining experimental/field data and expert opinion, the yearly risk of LSDV being introduced by stable flies (Stomoxys calcitrans), that travel in trucks transporting animals was between 6 x 10-5 and 5.93 x 10-3 with a median value of 89.9 x 10-5; it was mainly due to the risk related to insects entering farms in France from vehicles transporting cattle from the at-risk area. The risk related to the transport of cattle going to slaughterhouses or the transport of horses was much lower (between 2 x 10-7 and 3.73 x 10-5 and between 5 x 10-10 and 3.95 x 10-8 for cattle and horses, respectively). The disinsectisation of trucks transporting live animals was important to reduce this risk. CONCLUSION AND SIGNIFICANCE: The development of a stochastic QIRA made it possible to quantify the risk of LSD being introduced in France through the import of vectors that travel in trucks transporting animals. This tool is of prime importance because the LSD situation in the Balkans is continuously changing. Indeed, this model can be updated to process new information on vectors and the changing health situation, in addition to new data from the TRAde Control and Expert System (TRACES, EU database). This model is easy to adapt to different countries and to other vectors and diseases. [less ▲]

Q fever is a cosmopolitan disease affecting both humans and many animal species. Although sheep are often implicated in human Q fever outbreaks, the disease remains largely underestimated in meat sheep flocks. In order to fulfil this gap, a preliminary study was performed aiming to investigate the serological and molecular aspects of infection with Coxiella burnetii among meat sheep flocks in Belgium. Five Belgian sheep flocks were recruited for this work. Indirect ELISA was used, and in addition, real-time PCR was performed on samples of milk, rectal and vaginal swabs, to understand the dynamics of bacterial shedding. Despite the low overall apparent seroprevalence of 1.39% (95% CI: 0.04-7.5), a high rate of bacterial shedding was found, with 27.7% of tested sheep (N = 72) with a positive result to PCR, especially through the rectal and vaginal routes and in seronegative animals. Furthermore, Coxiella burnetii DNA was detected in 26.76% of seronegative animals. It can be concluded that an overall good clinical condition of the sheep cannot be used to exclude the presence of C. burnetii in a flock. Furthermore in the diagnosis of Q fever in sheep, serology alone was not a sensitive diagnostic tool. On the contrary, molecular biology allowed to detect bacterial shedding, which is an essential element in order to assess the risk due to the contact with shedding animals. At the light of these results, the role of meat sheep flocks in the epidemiology of Q fever in Belgium needs to be better understood. [less ▲]
