Tracking sero-molecular trends of swine brucellosis in Hawai'i and the central Pacific.

Introduction: Brucellosis is a zoonotic disease of mammals caused by bacterial species of the genus. The reservoir for disease is typically mammals, with species of found infecting amphibians, bats, and marine mammals. spp.

Serosurveillance of in feral swine populations of Hawai'i and Texas identifies overlap with human Q fever incidence.

Feral swine are invasive in the United States and a reservoir for infectious diseases. The increase in feral swine population and the geographic range are a concern for the spread of zoonotic diseases to humans and livestock. Feral swine could contribute to the spread of the causative agent of human Q fever.

Widespread Detection of Antibodies to Eastern Equine Encephalitis, West Nile, St. Louis Encephalitis, and Turlock Viruses in Various Species of Wild Birds from Across the United States.

Wild birds serve as amplifying hosts for many arboviruses, and are thought to be responsible for introducing these viruses into new areas during migration as well as reintroducing them to places where winter temperatures disrupt mosquito-borne transmission. To learn more about four mosquito-borne arboviruses of concern to human or animal health, we tested sera from 997 wild birds of 54 species and 17 families across 44 states of the United States collected from January 1, 2013, through September 30, 2013. Samples were tested for antibody against eastern equine encephalitis, St.

Multiplex serology for common viral infections in feral pigs (Sus scrofa) in Hawaii between 2007 and 2010.

Multiplex serology was performed for the detection of total immunoglobulin (Ig) and IgM antibodies against porcine circovirus type 2 (PCV2), porcine reproductive and respiratory syndrome virus (PRRSV), and swine influenza virus (SIV) antigens in feral swine (Sus scrofa). Serum samples were collected from the islands of Oahu (292 pigs) and Hawaii (52 pigs) between 2007 and 2010. The highest antibody prevalence was to PCV2 (63%), followed by SIV (7.

Identification of Brucella suis from feral swine in selected states in the USA.

Serologic tests currently available for brucellosis diagnosis detect antibodies to Brucella but do not distinguish between species of Brucella. Although Brucella suis is known to circulate within various feral swine (Sus scrofa) populations, our objective was to determine the primary species of Brucella circulating in feral swine populations in areas of the US with high brucellosis prevalence. We cultured lymph nodes from 183 feral swine.
