The Ontario Animal Health Network: enhancing disease surveillance and information sharing through integrative data sharing and management.

The Ontario Animal Health Network (OAHN) is an innovative disease surveillance program created to enhance preparedness, early detection, and response to animal disease in Ontario. Laboratory data and, where available, abattoir condemnation data and clinical observations submitted by practicing veterinarians form the core of regular discussions of the species-sector networks. Each network is comprised of government veterinarians or specialists, epidemiologists, pathologists, university species specialists, industry stakeholders, and practicing veterinarians, as appropriate.

Herd-level prevalence and incidence of porcine epidemic diarrhoea virus (PEDV) and porcine deltacoronavirus (PDCoV) in swine herds in Ontario, Canada.

Porcine epidemic diarrhoea virus (PEDV) and porcine deltacoronavirus (PDCoV) were first identified in Canada in 2014. Surveillance efforts have been instrumental in controlling both diseases. In this study, we provide an overview of surveillance components for the two diseases in Ontario (Canada), as well as PEDV and PDCoV incidence and prevalence measures.

Outbreak investigation of porcine epidemic diarrhea in swine in Ontario.

Porcine epidemic diarrhea virus was first diagnosed in Ontario in January of 2014. An outbreak investigation was conducted and it was hypothesized that feed containing spray-dried porcine plasma contaminated with the virus was a risk factor in the introduction and spread of the disease in Ontario.

Actinobacillus equuli as a primary pathogen in breeding sows and piglets.

The death of over 300 sows in 2 months on a 3000 sow farrow-to-isowean operation in Manitoba was attributed to infection with Actinobacillus equuli. This pathogen commonly infects foals, and is rarely reported in swine. Our report is the second recently published case of this pathogen in North American swine.
