The full-length cDNA clone of swine vesicular disease virus HK/70 strain named pSVOK was constructed in order to study the antigenicity, replication, maturation and pathogenicity of swine vesicular disease virus. transcription RNA from pSVOK transfected IBRS-2 cells and the recovered virus RNA were isolated and sequenced, then indirect hemagglutination test, indirect immunofluorescence assays, eleectron microscope test, 50% tissue culture infecting dose (TCID) assays and mouse virulence studies were performed to study the antigenicity and virulence of the recovered virus. The result showed that the infectious clones we obtained and the virus derived from pSVOK had the same biological properties as the parental strain HK/70. The full-length infectious cDNA clone, pSVOK, will be very useful in studies of the antigenicity, virulence, pathogenesis, maturation and replication of SVDV.

Peccaries (collared peccary-CP-and white-lipped peccary-WLP) are an essential source of protein and income for rural communities in the Amazon region. Since 1980s, researchers in the Amazon have reported recurrent local disappearances of WLP populations. Although such disappearances impact the species conservation and the food security of rural societies, no studies have drawn consistent conclusions about the causes of these population collapses.

Senecavirus A (SVA) is the causative agent associated with porcine idiopathic vesicular disease (PIVD), a condition indistinguishable from other foreign vesicular diseases affecting pigs. This complicates differential diagnosis and impacts the global swine industry. A diagnostic ELISA based on a non-structural viral protein has been developed, capable of distinguishing infected from vaccinated animals (DIVA).

During the past 25 years, vesicular stomatitis virus (VSV) has produced multiple outbreaks in the US, resulting in the emergence of different viral lineages. Currently, very little is known about the pathogenesis of many of these lineages, thus limiting our understanding of the potential biological factors favoring each lineage in these outbreaks. In this study, we aimed to determine the potential phenotypic differences between two VSV Indiana (VSIV) serotype epidemic strains using a pig model.

This is the first study aimed to investigate the innervation of the internal genital organs in 12-week-old female pig foetuses using single and double-labelling immunofluorescence methods. Immunostaining for protein gene product 9.5 (PGP, general neural marker) revealed that the most numerous PGP-positive nerve fibres were found in the mesenchyme of the uterovaginal canal height.

Senecavirus A (SVA) is an emerging pathogen that causes idiopathic vesicular infections in pig herds, posing a potential threat to their production performance. Heat shock protein 70 (Hsp70) is a molecular chaperone that plays an important role in host homeostasis under both physiological and stress conditions. However, the effects of Hsp70 on SVA infection and its underlying regulatory mechanisms remain unclear.
