Sixteen animals affected in 2 outbreaks of pet food-associated renal failure (2 dogs in 2004; 10 cats and 4 dogs in 2007) were evaluated for histopathologic, toxicologic, and clinicopathologic changes. All 16 animals had clinical and laboratory evidence of uremia, including anorexia, vomiting, lethargy, polyuria, azotemia, and hyperphosphatemia. Where(More)
The genomic RNA of a novel chicken astrovirus was determined. The full length sequence is 7520 nucleotides and encodes three open reading frames (1a, 1b, 2) for three proteins. The genomic organization was similar to other astroviruses with two exceptions. The open reading frame of the RNA-dependent RNA polymerase contains its own start codon which is(More)
A case of tuberculosis is reported in an eight-year-old, male, elk (Cervus elaphus nelsoni). The elk showed severe coughing, respiratory distress, abdominal breathing, anorexia, and severe progressive emaciation in the elk farm. At necropsy, the elk appeared in poor body condition. Mild enlargement of retropharyngeal and submandibular lymph node was(More)
This report deals with the acute onset of an abortion outbreak and high sow mortality in one pig herd consisted of 1,200 pigs and 120 sows on Jeju Island, Korea. Affected pregnant sows showed clinical signs, including high fever, gradual anorexia, vomiting, depression, recumbency, prostration, abortion, and a few deaths. Four dead sows, five aborted fetuses(More)
Currently, the aetiology of runting and stunting syndrome (RSS) in chickens is unknown. The impact of RSS on weight gain and microscopic lesions in immunological organs and the duodenum, was investigated in 1-day-old commercial broilers at 12 days following exposure to RSS-contaminated litter. Furthermore, the presence of the viral nucleic acids of three(More)
Pigs are believed to be one of the important sources of emerging human and swine influenza viruses (SwIV). Influenza virus conserved peptides have the potential to elicit cross-protective immune response, but without the help of potent adjuvant and delivery system they are poorly immunogenic. Biodegradable polylactic-co-glycolic acid (PLGA) nanoparticle(More)
The H5N1 highly pathogenic avian influenza (HPAI) virus was isolated for the first time in Egypt in 2006, since then, the virus has become endemic causing a significant threat to the poultry industry and humans. H5N1 HPAI outbreaks continue to occur despite extensive vaccination programs that have been implemented nationwide in different poultry species.(More)
Swine influenza virus (SwIV) is one of the important zoonotic pathogens. Current flu vaccines have failed to provide cross-protection against evolving viruses in the field. Poly(lactic-co-glycolic acid) (PLGA) is a biodegradable FDA approved polymer and widely used in drug and vaccine delivery. In this study, inactivated SwIV H1N2 antigens (KAg)(More)
Several different enteric viruses have been identified as the causes of gastrointestinal infections in poultry. Enteric virus infections are well characterized in poults, but limited studies have been conducted in older birds. The susceptibility of 2-, 7-, 12-, 30-, and 52-wk-old turkeys to turkey coronavirus (TCoV) and turkey astrovirus (TAstV) was(More)
We have recently demonstrated the effectiveness of an influenza A virus (IAV) subunit vaccine based on biodegradable polyanhydride nanoparticles delivery in mice. In the present study, we evaluated the efficacy of ∼200nm polyanhydride nanoparticles encapsulating inactivated swine influenza A virus (SwIAV) as a vaccine to induce protective immunity against a(More)
