PRRS: Time to stability and time to baseline production study
The purpose of this study was to compare efficacy of LCE (load-close-expose) using attenuated PRRSV to that using live-virus exposure on breeding herds acutely infected with PRRSv.

Infectious agents identified in aborted porcine foetuses
PCV-2 and PRRS are the most common infectious causes of abortions. Most abortions are also found to occur during the colder months, regardless of their cause.
Emergence of a virulent porcine reproductive and respiratory syndrome virus (PRRSV) 1 strain in Lower Austria
In the year following the outbreak, the same PRRSV strain was identified repeatedly in different regions of Austria. It can be speculated that the new strain has novel advantageous properties.
Cambodia confirms an outbreak of PRRS
An outbreak of porcine reproductive and respiratory syndrome (PRRS) has been reported in Li Nha, Tapheim, Tramkak (Takeo).
Immunisation of fattening pigs against influenza: a case study
The reasons behind the vaccination against influenza virus on a group of fattenig units with recurrent respiratory clinical pictures that belong to an integrated production system are discussed. Impact on production parameters and economic results are also shown.
Three projects win 2016 European PRRS research award
Boehringer Ingelheim Animal Health has sponsored European PRRS Research Award for the third time. The main aim of this award is to encourage research in the field of PRRS.
Outbreak Investigation of NADC30-Like PRRSV in South-East China
NADC30-like PRRSV has widely spread in China and could cause clinical disease on pigs.
PRRS & PEDV Control Proposal
PRRS & PEDV Control Proposal: Open Forum - Dr. David Wright, Wright Veterinary Services; Dr. Bill Hartmann, Minnesota Board of Animal Health, from the 2016 Minnesota Pork Congress.
Clinical case: One clinical picture of parvovirus, two separate causes
The farmer, alarmed, calls us describing a clinical picture of abortions in the last third of gestation, weak newborn piglets, stillbirths, mummified piglets, agalactia, sows with fever and small litters.
Health and economical impact of PRRS in Northern Ireland
The economic potential lost in a unit positive to PRRS could be around 35 – 37% of net unit margin.
Health protocols for replacements: respiratory and systemic diseases (2/3)
We are talking about PRRSV, M. hyo, PCV2, App and swine influenza virus.
Transdermal devices in PRRSV immunization (2/2)
Needle-free injection technology improves the dispersion of vaccines throughout the tissue.
Comparative efficacy of concurrent administration of a PCV2 vaccine plus a PRRSV in pigs challenged with both viruses
Under the conditions of this study, it makes no difference to protection whether PCV2 and PRRSV vaccines are administered concurrently. Concurrent vaccination is efficacious for controlling co-infection with PCV2 and PRRSV.
Measuring progress in PRRS regional control programs
Without the participation in the program of all farms present in the area, progress will be minimal or nil.
Transdermal devices in PRRSV immunization (1/2)
NFID administered swine vaccines can use half to a tenth of the dose required for intramuscular vaccines because of the higher antigen dispersion and contact with the antigen presenting cells found in skin.
Assessing impact of 174 PRRSv on wean to finish pig health
A method to quantify the relative economic importance of pig health status at placement by specific pathogens (PRRSv and PEDv) and to estimate the effect of a specific type of PRRSv at a specific production system is presented.
