Abstract Background The presence of wild pigs across the prairie provinces in Canada, coupled with their potential role as reservoirs for economically significant livestock pathogens, has intensified the need for surveillance. This study provides an overview of swine production-limiting diseases circulating within the invasive wild pig population in Alberta. Results Between 2018 and 2024, 331 individuals were captured and tested for 17 pathogens. Antibodies to Erysipelothrix rhusiopathiae (120/120; 100%), porcine circovirus 2 (PCV2, 38/120; 31.7%), Mycoplasma hyopneumoniae ( Mhyo , 2/96; 2.1%), and porcine reproductive and respiratory syndrome virus (PRRSV, 1/96; 1.0%) were detected. Gastrointestinal parasites were identified for Eimeria spp. (76/192; 39.6%); Metastrongylus spp. (49/192; 25.5%); Trichuris spp. (11/192; 5.7%); Ascaris spp. (11/192; 5.7%); and Strongyloides spp. (8/192; 4.2%). Molecular diagnostics confirmed infection with porcine circovirus 1 (PCV1, 1/331; 0.3%), PCV2 (109/331; 32.9%), porcine circovirus 3 (PCV3, 90/331; 27.2%), rotavirus A (RVA, 21/92; 22.8%), rotavirus C (RVC, 5/92; 5.4%), porcine parvovirus (PPV, 18/101; 17.8%), and Salmonella spp. (2/72; 2.8%). Porcine deltacoronavirus (PDCoV), porcine epidemic diarrhea virus (PEDV), Seneca virus A (SVA), transmissible gastroenteritis virus (TGEV), influenza A virus (IAV), and rotavirus B (RVB) were not detected. Age was significantly associated with PCV2 and PCV3 infection, with mature individuals exhibiting a higher risk ( p < 0.001) of being infected. Co-detection of pathogens was common, with 55.9% (38/68) of wild pigs testing positive for two or more pathogens. Conclusion Overall, wild pigs were infected with pathogens that are significant to the porcine production industry and public health, demonstrating the potential risk of transmission at the wild and domestic pig interface, and highlighting the importance of continued surveillance from a One Health perspective.

A nerve and mast cell sentinel system releases extracellular condensates to induce macrophage repair. · doi/link

Read abstract
There is a higher density of immune cells in peritoneal fluid than is found in blood. Thus, any perturbations, from sterile injury to endometriosis to ovarian cancer, require immune cells to recognize and nucleate to these sites. Using peritoneal injuries as a prototype, we saw a massive recruitment of large peritoneal macrophages (LPMs) interspersed with mast cells. The mast cells were activated by sensory neurons to mobilize their 1-μm granules to the cell surface. Lattice light sheet microscopy unveiled a new step in the mast cell degranulation. After granules fused with the plasma membrane, cytonemes (very thin long filopodia) grabbed the granules from the mast cell surface and deposited them on neighboring LPMs. The granules were membraneless biomolecular condensates and harbored more than 200 different proteins, including MARCO, which mediated rapid LPM aggregation to the injury nidus. The condensates also induced a repair-like phenotype in the macrophages that helped heal the injury site.
