Porcine encephalomyelitis can be associated with many etiologies, including viral agents, such as Porcine teschovirus (PTV), Porcine sapelovirus (PSV), and Porcine astrovirus (PoAstV). In this study, we investigated the presence of these viruses in a neurological disease outbreak in a swine farm in Southern Brazil. The piglet production farm unity had 1200 weaning piglets, and 40 piglets with neurological signs such as motor incoordination, paresis, and paralysis of hind limbs, with an evolution time of approximately 4 days.

- The study aimed to identify Angiostrongylus species infecting wild carnivores in Southern Brazil and examine the associated tissue damage.
- Necropsy of 16 infected animals revealed severe lung damage, including areas of consolidation, nodules, and some brain lesions related to the infection.
- Molecular analysis confirmed the presence of Angiostrongylus cantonensis and a closely related species, along with histological evidence of infection in different carnivore species.
This study reports the epidemiological, pathological and mycological findings of cutaneous pythiosis in cattle in southern Brazil. 23 calves, that were kept next to a river with extensive marshy regions, presented ulcerated cutaneous lesions in thoracic and pelvic limbs, sometimes extending to the ventral thoracic region. Histopathological examination revealed multifocal pyogranulomas in the superficial and deep dermis.
