Effect of intervention practices to control the porcine epidemic diarrhea (PED) outbreak during the first epidemic year (2013 to 2014) on time to absence of clinical signs and the number of dead piglets per sow in Japan
The objectives of the present study were to assess the effect of biosecurity measures and intervention practices to control PED on time to absence of clinical signs (TAC) and number of dead suckling piglets during TAC. A questionnaire was administered to 120-PED affected farms located across Japan between 2013, when the first case was reported in Japan, and 2014. Farms were asked to provide information on farm characteristics and internal or external biosecurity measures during PED outbreak, as well as on intervention practices to control PED. The TAC was defined as the number of days from the date that clinical PED signs ...

Composite or Aseptic Quarter Milk samples: Sensitivity and Specificity of PCR and Bacterial Culture of Staphylococcus aureus based on Bayesian Latent Class Evaluation
In this study, we used Bayesian LCA on a dataset from one sampling day at a Danish dairy herd to estimate the Se and Sp for detecting Staph. aureus at cow and quarter level. We used Ct cut-offs of 32 and 37 cycles for the qPCR. When using a cut-off of 37 cycles, the estimated Se and Sp for BC were 62.2% and 90.5% at cow level, and 90.7% and 93.5% at quarter level, respectively. Similarly, the estimated Se and Sp for qPCR at cow level were 82.7% and 84.1%, respectively, and 80.0% and 96.8% at quarter level. Sp was therefore higher for both BC and qPCR at quarter level. Se was also highest for BC at quarter level, but the op...

Short-term effects of air pollution and temperature on cattle mortality in the netherlands
ConclusionsBoth high and low temperatures were associated with increased mortality amongst pre-weaned calves of 15-55 days, whereas associations in weaned calves (56 days – 1 year) were only observed for low temperatures and in newborn calves of at most 14 days and lactating cattle>2 years only for high temperatures. Associations of air pollution with mortality in all age groups were not consistent, except for the effect of ozone of lag 0-7 and lag 0-25. (Source: Preventive Veterinary Medicine)

Simulation of transmission and persistence of African swine fever in wild boar in Denmark
Publication date: Available online 1 April 2019Source: Preventive Veterinary MedicineAuthor(s): Tariq Halasa, Anette Boklund, Anette Bøtner, Sten Mortensen, Lene Jung KjærAbstractAfrican swine fever (ASF) is caused by ASF virus (ASFV) and is currently circulating in the eastern part of Europe posing a serious risk regarding transmission to western European countries. Wild boar is a main driver of the transmission and persistence of ASFV in the endemic infected countries in Europe. Some European countries free from ASF, such as Denmark and the Netherlands, have limited population sizes of wild boar, but have la...
