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.
