Conteúdo: Os reovírus aviários (ARVs) estão entre os patógenos de maior importância econômica para a avicultura devido à sua ampla prevalência e ao seu potencial patogênico (Nour & Mohanty, 2025). Embora muitas cepas sejam assintomáticas, variantes patogênicas podem causar inflamação e danos teciduais. Em frangos de corte e perus, os ARVs podem induzir artrite/tenossinovite graves, resultando em claudicação, desuniformidade e aumento da mortalidade (Lu et al., 2015; Sellers, 2017; Palomino-Tapia et al., 2018). Há também uma forte associação entre ARVs e doenças como síndrome de má absorção (MAS), síndrome de nanismo/ atrofia (RSS) e imunossupressão, embora a associação dos ARVs nesses casos seja difícil (Dawe et al., 2023).2026-01-01T00:00:00ZBeyond human vision: computer vision systems offer new, innovative approaches to conducting inspections.ALBAN, L.BRANDÃO, D.DONDONA, A.

Conteúdo: ABSTRACT: Swinepox (SWPV), caused by Suipoxvirus, primarily affects pigs and typically presents progressive skin lesions. This study aims to describe and characterize an outbreak of SWPV on four subsistence-farming properties in the state of Santa Catarina, South region of Brazil. Clinical, histopathological, molecular, and immunohistochemical analyses were performed on skin samples from one pig per property. The outbreak involved four subsistence pig farms, affecting the herds with proliferative, crusted skin lesions. Skin samples from four pigs, one from each property, were collected and routinely processed for histopathological analysis. Immunohistochemistry (IHC) was performed using the peroxidase method with a polyclonal vaccinia virus antibody, and the Max Polymer Detection System was utilized. Frozen skin fragments underwent polymerase chain reaction (PCR) for Suipoxvirus, targeting the FP-DNApol/RP-DNApol sequences, amplifying 543 base pairs. Sequencing and phylogenetic analysis were performed using the Sanger method. The farm facilities were located near water reservoirs, where constant flies and mosquitoes plagued. The number of affected pigs was 14, 9, 21 and 2, respectively, in the four farms, resulting in 98% morbidity; however, no pig died. Macroscopically, erythematous and crusted lesions with a crateriform appearance were observed on the dorsal, ventral and limb regions, as well as the face, ears, and snout, associated with intense pruritus. Histopathology revealed proliferative pustular ulcerative dermatitis with eosinophilic intracytoplasmic inclusion bodies. The IHC showed positivity in the cytoplasm of epithelial cells for poxvirus 1/4, and the PCR was positive for SWPV in 3/4 cases. The phylogenetic analysis revealed 75% similarity with previously described Brazilian strains. After three weeks, the affected animals experienced spontaneous recovery from the disease. This study emphasizes the significance of disease monitoring in subsistence pig farming, particularly for differential diagnoses, as the observed lesions are suggestive of other viral agents, such as foot-and-mouth disease.2026-01-01T00:00:00ZShaping soil fungal communities: How swine waste treatment systems and geography drive fungal community shifts.DIEHL, C.BREYER, G.

Conteúdo: The use of swine waste as an organic fertilizer is an important practice in sustainable agriculture. This study aims to evaluate the effects of two common swine waste treatment systems, Covered Lagoon Biodigesters (CLB) and Waste Stabilization Ponds (WSP), on fungal community structure in soil. Soil and waste samples were collected from swine farms across five Brazilian states, representing different geographical regions with distinct climate, soil types, and vegetation. A metagenomic approach was employed to analyze the fungal communities present in the samples. Our results revealed that fertilization with swine waste did not significantly affect the overall diversity of fungal communities, although distinct shifts in community composition were observed between fertilized and non-fertilized soils. Notably, reads assigned to Sugiyamaella lignohabitans were detected only in samples from waste stabilization ponds, suggesting that this environment may favor fungal taxa associated with lignocellulose degradation. Furthermore, the fungal genera Fusarium and Rhizophagus exhibited contrasting responses to fertilization, with Fusarium being more abundant in fertilized soils and Rhizophagus decreasing in abundance. Geographic variation in fungal community composition was also observed, correlating with the physicochemical properties of the soil. These findings indicate that, in our dataset, the waste treatment systems had little influence on the fungal diversity of waste samples, whereas soil fertilization with swine waste was associated with marked shifts in fungal community composition, particularly in terms of taxonomic structure.2026-01-01T00:00:00Z
