Bioaerosol and surface sampling for the surveillance of influenza A virus in swine.

Influenza A virus in swine is of significant importance to human and veterinary public health. Environmental sampling techniques that prove practical would enhance surveillance for influenza viruses in swine. The primary objective of this study was to demonstrate the feasibility of bioaerosol and surface sampling for the detection of influenza virus in swine barns with a secondary objective of piloting a mobile application for data collection.

Development and Validation of a Standardized Tool for Prioritization of Information Sources.

Purpose: To validate the utility and effectiveness of a standardized tool for prioritization of information sources for early detection of diseases.

Methods: The tool was developed with input from diverse public health experts garnered through survey. Ten raters used the tool to evaluate ten information sources and reliability among raters was computed.

Swine influenza test results from animal health laboratories in Canada.

Due to its infrastructure and partnerships the Canadian Animal Health Surveillance Network was able to rapidly collect test results from 9 Canadian laboratories that were conducting primary testing for influenza on swine-origin samples, in response to the threat posed by the pandemic H1N1 influenza virus in 2009.

Mass depopulation of laying hens in whole barns with liquid carbon dioxide: evaluation of welfare impact.

Appropriate emergency disaster preparedness is a key priority for agricultural agencies to allow effective response to serious avian disease outbreaks. There is a need to develop rapid, humane, and safe depopulation techniques for poultry that are widely applicable across a range of farm settings. Whole barn depopulation with carbon dioxide (CO(2)) has been investigated as a humane and efficient means of killing large numbers of birds in the event of a reportable disease outbreak.

A minimum data set of animal health laboratory data to allow for collation and analysis across jurisdictions for the purpose of surveillance.

A minimum data set consisting of 15 data elements originating from laboratory submissions and results was formulated by a national committee of epidemiologists in Canada for the purposes of disease reporting, disease detection and analysis. The data set consists of both data that are filled out on the submission form as well as the results of the laboratory testing. The elements in the data set are unique identifier, premises identification, date submitted, geographic location, species, farm type, group type, total population of tested species on the farm, number sick, number dead, test(s) performed, disease agent, test result, disease classification by submitter and final laboratory diagnosis.

Effective animal health disease surveillance using a network-enabled approach.

There are many benefits that derive from real-time knowledge of the health status of the national livestock population. Effective animal disease surveillance is a requirement for countries that trade in live animals and their products in order to comply with the World Organization for Animal Health (OIE) guidelines. Rapid identification of introduced and emerging disease allows rapid response and mitigation of the economic consequences.

Mycoplasma felis pleuritis in two show-jumper horses.

Mycoplasma felis was identified as the cause of acute pleuritis in 2 show-jumping horses. The pleural exudate was proteinaceous, contained large numbers of neutrophils, and had a markedly increased lactate concentration. M.
