We herein describe several diagnostic cases of finisher pig colitis wherein both novel and common pathogens were discovered.Materials and Methods:Necropsies of 5 pigs, 10-13 weeks of age, with diarrhea and weight loss, were performed at two swine farms, each housing > 15,000 growi ...

Introduction: Most common influenza A virus (IAV) control measures include sow vaccination using prefarrow, mass or a combination of prefarrow and mass vaccination protocols with either commercial, autogenous or both vaccines. Piglets prior to wean are important in the maintenance of influenza infections in breeding herds as well as in the dissemination of the virus into wean-to-finish facilities. ...

Introduction:Over the last 15 years, genetically and antigenically distinct groups of influenza A viruses in swine (IAV-S) have emerged. The 2009 pandemic H1N1 virus and variant H3N2 viruses of swine-origin underscore the threat that IAV-S pose to public health. Consequently, there is greater need for increased IAV-S surveillance globally. This is particularly important in regions where there is v ...

Influenza A virus (IAV) is a member of the family Orthomyxoviridae possessing 8 negative sense single-stranded RNA segments and classified in subtypes based on the antigenicity of their surface glycoproteins: 18 subtypes for hemagglutinin (HA) and 11 subtypes for neuraminidase (NA). IAV can infect birds and several mammalian species, including human and swine. Pigs have an important role in the ec ...
