Plastination as an alternative method for the anatomical preservation and study of Brazilian herpetofaunaNARA Subscribed
The teaching and learning of zoology and comparative anatomy face several challenges, including the identification of anatomical structures across different species, understanding evolutionary relationships, and promoting science communication and public engagement. In addition, the fragility of formalin-fixed specimens subjected to repeated handling limits their long-term use in practical classes. Plastination has emerged as...
Genomic analysis of Escherichia coli, Enterobacter hormaechei, and Cupriavidus gilardii isolated from Cacatua albaNARA Subscribed
The objective of this study was to perform genomic, phylogenomic, and phenotypic characterization of bacterial isolates from a captive Cacatua alba to investigate their antimicrobial resistance profiles, virulence-associated genes, and genomic relationships with publicly available strains. Bacterial isolates obtained from the lungs and encephalon were identified as Escherichia coli (AV037), Enterobacter hormaechei (AV038), and...
Rapid identification of Sporothrix brasiliensis by MALDI-TOF MS directly from clinical cultures in an Amazonian epidemic settingNARA Subscribed
Sporotrichosis caused by Sporothrix brasiliensis is a highly virulent zoonotic mycosis rapidly expanding in Brazil, with increasing records in Pará since 2018. The reference diagnosis relies on culture and the time-consuming induction of fungal dimorphism, which delays taxonomic confirmation for weeks. The objective of the study was to develop and validate an in-house spectral library by MALDI-TOF MS for the rapid identificati...
The widespread use of aromatic herbicides such as 2,4-dichlorophenoxyacetic acid (2,4-D) has led to persistent environmental contamination, requiring efficient and sustainable biodegradation strategies. In this study, we isolated and characterized a novel actinobacterial strain, Streptomyces sp. SCPE-10, from contaminated coastal soil, capable of using 2,4-D as its sole carbon source. Phenotypic assays revealed robust growth o...
Anatomopathological aspects of osteoarticular lesions associated with Rhodococcus equi infection in two foalsNARA Subscribed
Rhodococcus equi is an important bacterium that affects foals up to six months of age, especially those that are immunocompromised. The main manifestation is pyogranulomatous pneumonia; nevertheless, extrapulmonary lesions have not only been reported, but are not uncommon, including arthritis and osteomyelitis. Despite the widespread occurrence of rhodococcosis, the macro- and microscopic lesions in the musculoskeletal system...
