Salmonella presents a significant threat to the health of animals and humans, especially with the rise of strains resistant to multiple drugs. This highlights the necessity for creating sustainable and efficient practical approaches to managing salmonellosis. The most recent and safest approach to combat antimicrobial resistance-associated infections is lytic bacteriophages.

Porcine epidemic diarrhea virus (PEDV) has caused significant harm to the global pig industry since its discovery. In this study, a highly pathogenic strain of GIIa PEDV CH/HBXT/2018, isolated previously, was continuously passaged in Vero cells up to passage (P)240, resulting in a completely attenuated virus. The proliferation characteristics of different passages of the strain in Vero cells, pathogenicity in newborn piglets, and mutations in S gene sequence indicated that as the passage number increased, the replication efficiency of PEDV in Vero cells gradually improved, with a more pronounced cytopathic effect.

Porcine reproductive and respiratory syndrome (PRRS) is an endemic disease affecting the swine industry. The disease is caused by the PRRS virus (PRRSV). Despite extensive biosecurity and control measures, the persistence and seasonality of the virus have raised questions about the virus's environmental dynamics during the fall season when the yearly epidemic onset begins and when crop harvesting and manure incorporation into the field occur.
