Evaluation of the efficacy of the Japanese rabies RC-HL strain vaccine in domestic dogs using past and present data: prediction based on logistic regression and meta-analysis
Publication date: Available online 18 September 2017 Source:Preventive Veterinary Medicine Author(s): Nigel C.L. Kwan, Akio Yamada, Katsuaki Suigiura Japan is one of the few rabies-free countries or territories (under the OIE standard) which still implement the policy of mandatory vaccination of domestic dogs. Under the Rabies Prevention Law enacted since 1950, pet owners in Japan are obliged to vaccinate their dogs every year. However, the national vaccination rate is estimated to average 42% over the past decade. Given this low owner compliance, there is debate over whether or not the mandatory vaccination policy should...

Comparison of antimicrobial resistance in E. coli isolated from rectal and floor samples in pens with diarrhoeic nursery pigs in Denmark
Conclusions We found that ETEC isolates were more resistant than Non-ETEC isolates. Furthermore, this study indicates that resistance testing of ETEC isolates from pen floor samples can be used as a convenient sampling method for resistance testing and in the selection of clinically relevant antimicrobial agents in the treatment of diarrhoeic pigs. The herd-level variation of resistance in ETEC isolates emphasises the importance of performing antimicrobial susceptibility testing at farm level when selecting antimicrobial agents for the treatment of E. coli-related diarrhoea.

The objective was to determine the time necessary to inactivate AIV in poultry litter at temperatures achievable in a poultry house. Low pathogenic (LP) AIV inactivation was evaluated between 10.0°-48.9° C, at ∼5.5° C intervals and highly pathogenic (HP) AIV inactivation was evaluated between 10.0°-43.3° C, at ∼11° C intervals. Samples were collected at numerous time points for each temperature. Virus isolation in embryonating chicken eggs was conducted to determine if viable virus was present. Each sample was also tested by real-time RT-PCR. Low pathogenicity AIV was inactivated at 1day at ...

Risk assessment of the entry of canine-rabies into Papua New Guinea via sea and land routes
This study provides a foundation to develop targeted border control measures, surveillance and response strategies for canine-rabies for the highest risk routes and regions in PNG. Sensitivity analysis using the Sobol method played a key role in this study and directed further data collection to refine risk estimates. The ease of expert-elicitation using online methods demonstrates the feasibility of using such methods for animal and human disease surveillance in PNG. (Source: Preventive Veterinary Medicine)

Persistence of Mycoplasma hyopneumoniae sequence types in spite of a control program for enzootic pneumonia in pigs
Publication date: Available online 26 June 2017 Source:Preventive Veterinary Medicine Author(s): Gudrun Overesch, Peter Kuhnert Enzootic pneumonia (EP) in pigs caused by Mycoplasma (M.) hyopneumoniae has successfully been combatted in Switzerland. A control program was fully implemented in 2004 which is based on total depopulation strategies of affected fattening farms as well as partial depopulation on breeding farms. Thereby, the number of cases has dropped drastically from more than 200 in 2003 to two cases in 2013. Currently monitoring is done based on clinical observation and subsequent diagnostic of coughing pigs. M...

Validation of a model for ranking aquaculture facilities for risk-based disease surveillance
The objective of the present study was to validate this model using data collected during field visits on aquaculture sites in four Swiss cantons compared to data collected through a questionnaire in the previous study. A discrepancy between the values obtained with the two different methods was found in 32.8% of the parameters, resulting in a significant difference (p<0.001) in the risk classification of the facilities. As data gathered exclusively by means of a questionnaire are not of sufficient quality to perform a risk-based surveillance of aquaculture facilities a combination of questionnaires and farm inspect...

Mortality in Danish Swine herds: Spatio-temporal clusters and risk factors
Publication date: Available online 20 June 2017 Source:Preventive Veterinary Medicine Author(s): Ana Carolina Lopes Antunes, Annette Kjær Ersbøll, Kristine Bihrmann, Nils Toft The aim of this study was to explore spatio-temporal mortality patterns in Danish swine herds from December 2013 to October 2015, and to discuss the use of mortality data for syndromic surveillance in Denmark. Although it has previously been assessed within the context of syndromic surveillance, the value of mortality data generated on a regular and mandatory basis from all swine herds remains unexplored in terms of swine surveillance i...
