Livestock-associated methicillin-resistant Staphylococcus aureus clonal complex 398 (LA-MRSA CC398) is causing an increasing number of skin and soft tissue infections (SSTIs) in Denmark and other European countries with industrial pig production. Yet, its impact on MRSA bloodstream infections (BSIs) has not been well studied.

A novel pestivirus species was discovered in a piglet-producing farm in Austria during virologic examinations of congenital tremor cases. The emergence of this novel pestivirus species, provisionally termed Linda virus, in domestic pigs may have implications for classical swine fever virus surveillance and porcine health management.

The aim of this study was to develop an epidemiological and economic model to determine the costs of PRRS for an individual pig farm.

Here we analyzed the molecular variations and antigenic differences among the C-strain-based commercial vaccines of different origins from different manufacturers in China, and reevaluated the vaccines against the emerging subgenotype 2.1d strain of CSFV.

Epidemiological investigations were conducted on a case series of six Senecavirus A (SVA)-affected breeding herds in the United States. Multiple potential routes of introduction were identified.

These findings demonstrate that diagnosis of M. hyosynoviae-associated arthritis can be influenced by the clinical isolate, and provides a study platform to investigate the colonization and virulence potential of field isolates.

The reduction in infectious agents in the air by the EPI technology could potentially decrease the microbial exposure for pigs.

Reducing the use of antimicrobials in food-producing animals may be achieved through more widespread use of RLP. Regional intravenous limb perfusion of an antimicrobial to treat lameness is feasible in swine.

The greatest frequencies of resistance were observed to tetracycline, trimethoprim/sulphamethoxazole and streptomycin with the highest levels of resistance observed in isolates from first-stage weaned pigs.

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.

PEDV transmission through contaminated PPE occurs rapidly under modeled conditions. Biosecurity procedures are recommended.

This review provides an update on bacteriocins and their potential for use in the swine industry.

Recombinant Ad5-O1Man is an effective, safe and cross-reacting vaccine that could potentially be used preventively and in outbreak situations, to control FMDV O Mya-98 lineage in swine.

Dietary supplementation with microalgae as an alternative to antibiotic use was studied.

These results further demonstrated the potential use of oral fluids for detecting FMDV genome, live virus, and viral antigens.

It is important to study the diversity of the strains of Yersinia enterocolitica in order to better understand the risk they represent for humans.

In all three cases we characterized the genome of a new circovirus we called PCV3.

This study showed a massive occurrence of ST398-MRSA in two independent swine farms.

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

We studied the change in amounts of antimicrobials prescribed for weaners and finishers in Danish herds duriong 2007-2013 following initiation of vaccination against five common endemic infections.

This study implies a metabolic adaptation of A. pleuropneumoniae to the porcine upper respiratory tract already during early infection.

Researchers from the IRTA-CReSA in collaboration with researchers from the Erasmus University Medical Center Rotterdam (the Netherlands), studied the susceptibility of different animal species to infection with MERS-CoV.

There is an increasing concern in several European countries over the role that tuberculosis (TB)-infected wild boar may play in the progress of bovine TB eradication campaigns. In Spain, the wild boar is the main wild reservoir of tuberculosis.

Results indicate that B. hyodysenteriae has a high degree of serological heterogeneity that has probably differently developed in diverse geographical areas over time.
