levels of illness but low death rates in pigs. These viruses may circulate among pigs throughout the year, but most outbreaks occur during the autumn and winter months, similar to flu outbreaks in humans. The classical swine flu virus (an H1N1 virus) was first isolated from a pig in 1930. Like all influenza viruses, swine flu viruses change constantly. Pigs can be infected by avian influenza an...

The economic analysis performed in this study is based on consolidated data from 48 groups of commercial finisher swine classified by three levels of Salmonella and on industry data. Each swine grouping had from 900 to 9,000 swine. The groupings were comprised of the same management and genetics, and were provided the same feed rations and diets throughout the study. The study group and compari...

After multiple discrete introductions of influenza A(H1N1)pdm09 virus into Sri Lanka, the virus was transmitted among humans, then swine. The spread of virus between geographically distant swine farms is consistent with virus dispersal associated with a vehicle used for swine transportation, although this remains unproven.

Activation of swine pepsinogen with chicken pepsin results in the formation of swine pepsin. Activation of chicken pepsinogen with swine pepsin results in the formation of chicken pepsin. The structure responsible for the species specificity of the enzyme is therefore present in the inactive precursor.

The swine gastrointestinal tract and stored swine manure may serve as reservoirs of antibiotic resistance genes, as well as sources of novel bacteria. Here, we report the draft genome sequence of a novel taxon in the Erysipelotrichaceae family, isolated from a swine manure storage pit that is resistant to multiple antibiotics.

Due to dual susceptibility to both human and avian influenza A viruses, pigs are believed to be effective intermediate hosts for the spread and production of new viruses with pandemic potential. In early 2008, two swine H5N2 viruses were isolated from our routine swine surveillance in Korea. The sequencing and phylogenetic analysis of surface proteins revealed that the Sw/Korea/C12/08 and Sw/Ko...

We performed antigenic analysis of the haemagglutinin and neuraminidase subunits of a recombinant virus (A/swine/Kanagawa/2/78) isolated from a pig in Japan in 1978, using a series of monoclonal antibodies to H1 (Hsw1) haemagglutinin and N2 neuraminidases of H2N2 and H3N2 viruses. Results obtained in haemagglutination inhibition tests with five monoclonal antibodies to the haemagglutinin of A/N...

Either living or heat-killed H. influenzae suis vaccines, given intramuscularly to swine, elicit an immune response capable of modifying the course of a later swine influenza infection. The protection afforded is only partial and is in no way comparable to the complete immunity afforded by swine influenza virus vaccines.

Resistance to Treponema hyodysenteriae (serotypes 1, 2, 3, and 4) infection was evaluated in ligated colonic loops in pigs recovered from swine dysentery. Lesions were present in most loops from recovered swine inoculated with heterologous serotypes; however, lesions were not present in loops of recovered swine inoculated with homologous serotypes.
