Disinfection protocols reduce the amount of porcine circovirus type 2 in contaminated 1:61 scale model livestock transport vehicles

چکیده
Materials and methods: Each model trailer was contaminated with intestinal content from a pig experimentally infected with PCV2, washed, and disinfected with one of four protocols. Between protocol steps, swabs were collected from six different areas of each trailer and tested for PCV2 DNA. Disinfection protocols were quaternary ammonium compound (DISF1), oxidizing agent containing potassium peroxomonosulfate (DISF2), combined glutaraldehyde and quaternary ammonium product (DISF3), and DISF2 followed by sodium hypochlorite compound (DISF4). Four PCV2contaminated, nonwashed, nondisinfected trailers served as positive controls and an uncontaminated trailer as negative control. Two 6to 10-week-old PCV2-naive pigs were placed in each cleaned and disinfected trailer for 2 hours. Blood samples collected weekly for 7 weeks were tested for antiPCV2 IgG antibodies and PCV2 DNA.

Planned exposure to porcine circovirus type 2 by serum injection is not effective at preventing porcine circovirus associated disease
s describing uncontrolled field observations. The objective of this study was to evaluate the efficacy of serotherapy in protecting against PCV2 infection and development of associated lesions and clinical signs under controlled laboratory conditions. Serum for serotherapy was collected from pigs at the acute and convalescent stages of experimental PCV2 infection and from pigs with high levels ...

The goal of this study was to evaluate survival of important viral pathogens of livestock in animal feed ingredients imported daily into the United States under simulated transboundary conditions. Eleven viruses were selected based on global significance and impact to the livestock industry, including Foot and Mouth Disease Virus (FMDV), Classical Swine Fever Virus (CSFV), African Swine Fever V...
متن کاملInfluence of porcine circovirus type 2 vaccination on the probability and severity of pneumonia detected postmortem
To evaluate the influence of porcine circovirus type 2 vaccination (PCV-2) on the probability and severity of pneumonia, postmortem findings of 247,505 pigs slaughtered between 2008 and 2011 were analysed by applying a cumulative link mixed model. Three major effects could be observed: (1) PCV-2 vaccination significantly (P<0.01) reduced the odds (coefficient: -0.05) of postmortem findings of m...

The porcine circovirus type 2 (PCV2) antibody and DNA status of porcine plasma products collected during the commercial spray-drying process were evaluated. Samples evaluated included 52 pooled liquid plasma (fresh) samples collected at 14 regional abattoirs before transport to 1 of 2 spray-drying facilities, 32 pooled liquid plasma (concentrated) samples collected after arrival at the spray-dr...
متن کاملInsights into the evolutionary history of an emerging livestock pathogen: porcine circovirus 2.
Porcine circovirus 2 (PCV2) is the primary etiological agent of postweaning multisystemic wasting syndrome (PMWS), one of the most economically important emerging swine diseases worldwide. Virulent PCV2 was first identified following nearly simultaneous outbreaks of PMWS in North America and Europe in the 1990s and has since achieved global distribution. However, the processes responsible for t...
