Bovine tuberculosis (bTB) is a chronic infectious disease caused by Mycobacterium bovis , which has major veterinary, economic, and zoonotic relevance. This study aimed to characterize the histopathological patterns of bTB lesions and their association with molecular detection in cattle slaughtered in Southern Brazil. Thirty-six tissue samples with lesions suggestive of bTB were collected during municipal inspection in Pelotas...
Habitat-associated detection of Toxoplasma gondii and Sarcocystis spp. in Cetaceans from the Brazilian coastNARA Subscribed
Cetaceans are sentinels of marine ecosystem health and are increasingly exposed to protozoal pathogens. This study investigated the occurrence and molecular identity of Sarcocystidae protozoa in 159 stranded cetaceans representing 21 species along the Brazilian coast. Molecular analysis based on PCR amplification and sequencing of the sarcocystid internal transcribed spacer 1 (ITS1) region revealed infections in 14 individuals...
Although Geographic Information Systems (GIS) have proved to be reliable tools for animal health management, their implementations in the aquatic animal health (AAH) domain are scarce, likely because they require expertise in GIS technologies, the specific characteristics of aquatic environments, and epidemiology. Considering the lack of GIS approaches tailored to AAH, this study presents a framework conceived to guide GIS use...
