Fetal pneumonia and polyarthritis associated with Ureaplasma diversum infection in an aborted beef cattle fetus in BrazilNARA Subscribed
Ureaplasma diversum is an opportunistic bovine pathogen associated with reproductive disorders, including infertility, granular vulvovaginitis, placentitis, and abortion; however, detailed descriptions of fetal osteoarticular lesions remain exceptionally uncommon. This report describes the gross, histopathological, and molecular findings of a bovine abortion associated with U. diversum infection presenting with concurrent pulm...
Forests and natural environments are valuable sources of organisms capable of degrading plant cell wall carbohydrates. In the present study, two isolates, Penicillium polonicum and Penicillium chrysogenum , obtained from Brazilian Cerrado soil, along with a previously characterized isolate of Trichoderma harzianum , were evaluated for their ability to produce carbohydrate-active enzymes when grown in the presence of wheat bran...
Multimodal microscopic and spectroscopic characterisation of heterogeneous iron oxyhydroxides in the human globus pallidusNARA Subscribed
Iron is essential for neuronal metabolism, neurotransmitter synthesis, and enzymatic function; however, dysregulated accumulation contributes to oxidative stress and neurodegeneration. The basal ganglia, particularly the globus pallidus , represent a hotspot for iron deposition, yet the precise structural forms and their implications remain incompletely understood. Here, a multimodal approach was applied combining Raman micros...
Biodegradation of Diuron By Indigenous Soil Bacteria Isolated From Herbicide-contaminated SitesNARA Subscribed
Residual herbicides are widely used in weed management; however, their persistence in the environment can lead to agronomic and ecological impacts. This study assessed bacterial isolates obtained from sugarcane soil with a history of diuron exposure for their ability to increase diuron dissipation under controlled conditions. Forty-two bacterial isolates were obtained, of which 18 tolerated the commercial formulation at 1,000...
Soil microbial communities underpin ecosystem functions critical for sustainable agriculture, yet our understanding of how long‐term management of tropical agroecosystems shapes these communities remains limited. This is particularly the case in sub‐Saharan Africa where soil health challenges are most acute for food security. Using four long‐term (~20 years) experiments across contrasting agroecological zones in Kenya, we stud...
Urban freshwater ecosystems are increasingly exposed to mixtures of pollutants, including per- and polyfluoroalkyl substances (PFAS). However, their ecological effects remain poorly understood, especially in tropical regions with limited sanitation infrastructure. This study investigated PFAS contamination, water quality, and microbial community structure in Pampulha Lake, a tropical urban reservoir in southeastern Brazil. Spa...
