PRRS around the World

Porcine Reproductive & Respiratory Syndrome (PRRS) around the World – What’s new regarding Global cross‐protection against PRRS - Dr. PH Rathkjen, Boehringer Ingelheim, from the 2016 North American PRRS Symposium, December 3‐4, 2016, Chicago, Illinois, USA.

Emergence of a novel highly pathogenic PRRSV in China

This study showed that the novel variant PRRSV was HP-PRRSV, and it is therefore critical to monitor PRRSV evolution in China and develop a method for controlling PRRS.

Comprehensive online management biosecurity assessment tool

New tool is part of suite of solutions to improve farm biosecurity and control of PRRS (Porcine Reproductive and Respiratory Syndrome).

First occurrence of PRRS in Ecuador

This is the first occurrence of PRRS in the country. The focus has been located on a commercial farm in Santo Domingo de los Tsachilas.

Molecular evolution of PRRS viruses circulating in Vietnam from 2007 to 2015

This study expands existing knowledge on the genetic diversity and evolution of PRRSV in Vietnam.

PRRSV surveillance on the breeding herd - is oral fluids from suckling piglets an alternative?

Oral fluids are practical, fast, easy, cost-effective and reliable methods for sampling pig populations, but it has not been easy or practical to obtain such samples from suckling piglets...

Sketch showing a bronchoalveolar lavage and bronchial scraping

Sampling for the detection of agents of the porcine respiratory disease complex: Bronchoalveolar lavage or bronchial scraping?

Many veterinarians find bronchial scraping a less invasive and, above all, simpler sampling method than bronchoalveolar lavage.

Summary On Recent Time-to-PRRS-Stability Research

Summary On Recent Time-to-PRRS-Stability Research - Dr. Daniel Linhares, from the 2016 Allen D. Leman Swine Conference, September 17-20, 2016, St. Paul, Minnesota, USA.

PRRSV control using vaccination and optimized management: three case studies

Although the use of vaccination was effective in stabilizing the sows, the results of these case studies emphasized that elimination of PRRSV from the nursery can only be accomplished if vaccination and partial depopulation/ disinfection are supported by strict implementation of all recommended management procedures, including AI/AO.

Clinical case: Multifactorial respiratory process at nursery and finisher

This case report highlights the importance of a comprehensive approach to achieve a correct differential diagnosis.

Precision engineering for PRRSV resistance in pigs

Precision engineering for PRRSV resistance in pigs: Macrophages from genome edited pigs lacking CD163 SRCR5 domain are fully resistant to both PRRSV genotypes while maintaining biological function

Virulent strain of PRRS virus

Humoral immune responses and viral shedding following vaccination with modified live PRRSv vaccines

The antibody response and pattern of shedding of vaccine virus following vaccination with modified live genotype I or II porcine reproductive and respiratory syndrome virus (PRRSV) vaccines (MLVs) were investigated.

Assessment of different samples to detect main swine respiratory pathogens

The data present bronchial scraping as an equally effective or even better alternative to bronchoalveolar lavage fluid for detecting main porcine respiratory disease complex agents.

The role of the microbiome in PRRS

By Dr. Megan Niederwerder, Diagnostic Medicine/Pathobiology, Kansas State University, from the 2016 North American PRRS Symposium, December 3‐4, 2016, Chicago, Illinois, USA.

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.
