Reflecting on 20 years of PRRS
PRRS creates frustrating challenges as it seems we have to keep learning the same lessons we already know, along with the occasional new chapter.

COVID-19 and pig viruses – what can we learn?
Lessons learnt from two of the most important virologists of the north American swine industry, Dra. Torremorell and Dra. Culhane, from other coronavirus outbreaks than spread globally within the swine industry.

05-Jun-2020ralphcookI wouldn't be so confident about the origin of the disease in wildlife. Yes, certainly bats are involved at some point perhaps decades ago but none of the suggested intermediary wild animals have been proven to have passed the virus to humans. Genetically, all the identified "similar" viruses found in truly wild animals have been too distant from the human version to have been its ancestor. The virus found in "wild" animals sold in the wet markets have conversely been too closely related to be the ancestor. They are quite likely to be the same virus passed to them by their human predators. We know from the second small SARS outbreak in 2004 that the farmed "wild" animals most clearly "implicated in the transmission to a small number of people", almost certainly received the virus from people first. I am more inclined to link events in China, between 2017-2019 to the outbreak of Covid-19, namely the attempts to control African Swine Fever in the national pig herd.
Flu control: don’t forget the piglet!
Nurse sows may represent a source of infection to the newly adopted pigs.

Use of processing fluids for PRRSV diagnostics
We propose to use the processing fluids, the liquid accumulated at the bottom of the pail when farmers collect tails and testicles during routine procedures as a sample.

09-Nov-2020ytran876is there any difference between castration fluid and tail docking fluid? can they use interchangeably or they have to go together for testing?
Impact of an early exposure to SIV and PRRSv in post-weaning mortality
Infection with swine influenza virus and porcine reproductive and respiratory syndrome during the suckling period was associated with an increase in post-weaning mortality (more limited in the case of SIV and of larger magnitude for PRRSV).

Air cleaning technologies for the control of airborne pathogens
The most direct strategy to decrease the concentration in the air of airborne pathogens is dust reduction. This article describes the use of a particle ionization system called EPI.

Duration of influenza infections in weaned pig populations
Influenza infections are self-limiting at the individual animal level with infection lasting between 5 and 7 days approximately. However, influenza virus is considered endemic in swine populations worldwide, and is not uncommon to find between 3 and 5% of pigs positive to influenza virus at slaughter.

PRRS virus elimination: How to prove herd negativity?
One of the challenges when conducting a disease elimination project is to ensure that the pathogen has in deed been eliminated from the herd.

As better information systems capable to measure change in disease patterns, vector distribution and environmental conditions are put in place, we may be surprised about the range of diseases directly or indirectly already affected by climate change.

Current sanitary problems in the United States
The focus of swine production in the USA has changed over the last five years. Many businesses in the sector have made radical changes in management both from the reproductive and the sanitary point of view.

19-Jul-2010Dinesh BogatiThe burning topic of swine flu has threaten all the farmers not only in USA but also in all over the world. To escape from health hazard all the farmer must be trained such as critical care jobs for the betterment of farmers and all the domestic animals.
