Background: Colibacillosis caused by is one of the main problems in the swine industry. In addition, the emergence of antimicrobial resistance and the combination of virulence genes among pathotypes have led to the emergence of more virulent pathogenic strains. Phage therapy has become a promising approach to address these issues.
Materials And Methods: Virulence genes for intestinal pathogenic (IPEC) and extraintestinal pathogenic (ExPEC) were investigated in pathogenic isolated from pigs. In addition, two potential phages, vB_EcoM-RPN187 and vB_EcoM-RPN226, isolated in our previous study, were further characterized in this study.
Results: Both phages were lytic and were highly effective at 20-37°C. Interestingly, they infected the hybrid IPEC/ExPEC strains. vB_EcoM-RPN187 and vB_EcoM-RPN226 possess 167 kbp of linear double-stranded DNA without virulence or antibiotic resistance genes and may be classified as new phage species in the genera and , respectively.
Conclusion: Both phages could be promising candidates for phage therapy against pathogenic .

Introduction: Non-Celiac Gluten Sensitivity (NCGS) is a common disorder characterized by symptoms resembling those of irritable bowel syndrome. In recent years there has been progress in the understanding of the pathogenic pathways and data suggest that NCGS has a distinct immunological profile that differs from celiac disease (CeD). This has fostered the search for a specific biomarker of NCGS.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

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.

A major health and financial burden in the chicken sector is salmonella infection. It is difficult to create an oral vaccination that can provide strong intestinal mucosal immunity in birds, particularly cross-protection against several Salmonella serotypes. As a result, the poultry industry needs a powerful oral vaccination platform that uses live bacterial vectors to prevent various Salmonella serotypes.

Interactions between bacteriophages with mammalian immune cells are of great interest and most phages possess at least one molecular pattern (nucleic acid, sugar residue, or protein structure) that is recognizable to the immune system through pathogen associated molecular pattern (PAMP) receptors (i.e., TLRs).
