background: influenza a virus is the most virulent human pathogen and causes the most serious problem. having epidemiological knowledge about this disease is important. the aim of this study was to determine the prevalence of influenza a/h3n2 virus infection in northern iran from 2011 to 2013 using the real-time polymerase chain reaction (rt-pcr). methods: in this cross-sectional study 57 sampl...

Feral swine (Sus scrofa) are present in 38 of the 50 United States, and their populations continue to expand. Domestic swine are widely regarded as vulnerable to diseases harbored by feral swine. Our objectives were to determine antibody prevalence for selected pathogens in Texas feral swine populations and identify contact events between feral and domestic swine. Overall prevalence of antibodi...

This file includes the 2022 Swine Day Research Report introduction, standard abbreviations, K-State Vitamin and Trace Mineral Premixes statement, biological variability chances of error explanation, acknowledgments our supporters. We hope that information in will be benefit as we attempt to meet needs Kansas swine industry.

Experimental studies of foot-and-mouth disease (FMD) in feral swine are limited, and data for clinical manifestations and disease transmissibility are lacking. In this report, feral and domestic swine were experimentally infected with FMDV (A24-Cruzeiro), and susceptibility and virus transmission were studied. Feral swine were proved to be highly susceptible to A-24 Cruzeiro FMD virus by intrad...

UNLABELLED Human-like swine H3 influenza A viruses (IAV) were detected by the USDA surveillance system. We characterized two novel swine human-like H3N2 and H3N1 viruses with hemagglutinin (HA) genes similar to those in human seasonal H3 strains and internal genes closely related to those of 2009 H1N1 pandemic viruses. The H3N2 neuraminidase (NA) was of the contemporary human N2 lineage, while ...

Nine swine slaughter plants and 19 swine production units were randomly selected for sampling from the six highest swine-producing states representing a total of 64% of the United States swine production. Three composites of 10 fresh swine fecal samples were obtained from each slaughter plant, representing three different farm sources of swine. Two composite fecal samples were collected from tw...

Swine recovered from infection with either swine influenza or swine influenza virus alone are usually not only immune but refractory to human influenza infection. Swine recovered from infection with a mixture of human influenza virus and H. influenzae suis are usually immune to swine influenza while those recovered from infection with human influenza virus alone are usually not immune to swine ...

background: timely notification is of great importance in health emergencies. so identifying the most important sources of information used by people in emergencies seems necessary. the objective of this study was to assess peoples’ level of awareness concerning the symptoms, routes of transmission, prevention, and treatment of h1n1 at the time of the pandemic and also to identify their most im...

Feral swine (Sus scrofa) have been introduced throughout North America from various global locations (Mayer and Brisbin 1991). In some cases, sources for feral swine are provided through historical records, but for many newly established populations, the origins of feral swine are not known. Understanding the origins and dispersal patterns of feral swine is an important management consideration...
