pseudorabies/diarrhea

Pancreatin is a substance containing enzymes, principally amylase, lipase, and protease. It is obtained from bovine or porcine pancreas and used in the treatment of pancreatic endocrine insufficiency in humans. Regulations and safety concerns mandate viral clearance (virus removal or inactivation)

Porcine epidemic diarrhea virus (PEDV) can cause serious disease and even death in neonatal piglets, resulting in serious damage to the swine industry worldwide. Open reading frame 3 (ORF3) is the only accessory gene in the PEDV genome. Previous studies have indicated that PEDV vaccine strains have

In this study, a reverse transcription loop-mediated isothermal amplification (RT-LAMP) was developed for detection of porcine epidemic diarrhea virus (PEDV). Six primers were designed to amplify the nucleocapsid (N) gene of PEDV. The optimization, sensitivity, and specificity of the RT-LAMP were

A loop-mediated isothermal amplification (LAMP) assay was developed specifically for detection and differentiation of pseudorabies virus (PRV). One group of primers was designed to detect wild-type strains (i.e., strains with the gE gene) and the other group of primers was designed to detect both

An outbreak of severe pseudorabies virus (PRV) infection in farmed mink occurred in northern China in late 2014, causing significant economic losses in the local fur industry. Here, we report the first case of a PRV outbreak in mink in northeastern China, caused by feeding farmed mink with raw pork

In early 2011, the serious outbreak of porcine pseudorabies virus (PRV) infection suddenly recurred in Henan and neighboring Provinces. To investigate the etiology of massive infection with PRV, 16 800 serum samples, 905 porcine epidemic diarrhea virus (PEDV) back-feeding tissues, and 56 PR gene

Butorphanol tartrate (BT) was injected into mice before injection with acetylcholine in a murine model infected latently with pseudorabies virus. The analgesic effect and its influence on virus reactivation were observed. Mice preinjected with BT showed suppression of screaming, moving and

Pseudorabies virus (PRV) variants broke out in china since 2011, causing high fever, respiratory distress, systemic neurological symptoms, and diarrhea in piglets. This study investigated the effect of intranasal PRV variant (AH02LA) infection on ileal and colonic bacterial communities and immune

A membrane (M), protein-based ELISA was developed to detect porcine epidemic diarrhea virus (PEDV). The M gene of PEDV was expressed in Escherichia coli. The purified recombinant M protein was used to immunize rabbits to generate a polyclonal antibody. Immunofluorescence analysis indicated that the

Pseudorabies is caused by Suid herpesvirus 1, a member of the Alphaherpesvirinae subfamily. Although pigs are the natural host of Pseudorabies virus (PRV), the virus has a broad host range and may cause fatal encephalitis in many species. The United States obtained PRV-free status in 2004 after the

Advances in molecular testing and microfluidic technologies have opened new avenues for rapid detection of animal viruses. We used a centrifugal microfluidic disk (CMFD) to detect 6 important swine viruses, including foot-and-mouth disease virus, classical swine fever virus, porcine reproductive and

We studied the efficacy of virus reduction by three process steps (polyethylene glycol 4000 (PEG) precipitation, pasteurization, and 15nm virus filtration) in the manufacturing of C1-inhibitor NF. The potential prion removing capacity in this process was estimated based on data from the literature.

BACKGROUND Freeze-drying is a technology widely used during the production of plasma-derived medicinal products. Several studies have shown that freeze-drying can also result in virus inactivation and particularly of hepatitis A virus (HAV). To date, however, the variables critical for virus

OBJECTIVE Cartilage injury is one of the most common disorders of synovial joints. Fresh osteochondral allografts are becoming a standard treatment; however, they are supply constrained with a potential risk of disease transmission. There are no known virucidal processes available for osteochondral
