Flies from meat processing facilities are carriers of multidrug-resistant Escherichia coli and diverse Staphylococcaceae speciesNARA Subscribed
Flies are important vectors of antimicrobial resistance (AMR) in food production, but their role in meat processing environments remains poorly characterized. This study isolated Enterobacteriaceae and Staphylococcaceae (including Mammaliicoccus sciuri ) from flies collected in bovine and swine slaughterhouses and meat processing industries. Phenotypic AMR was assessed, and the presence of selected antimicrobial resistance and...
First report of a species of Senga (Cestoda: Bothriocephalidae) in commercial Betta splendens (Actinopterygii: Osphronemidae) in BrazilNARA Subscribed
Species of the genus Senga comprise a group of bothriocephalidean cestodes that predominantly parasitize freshwater teleost fishes, causing severe histopathological alterations due to scolex attachment to the digestive tract or obstruction of the intestinal lumen. The Siamese fighting fish Betta splendens is the type-host of Senga besnardi , the type species of the genus known only from the original description. Despite the im...
Cetaceans are highly adapted marine mammals whose survival depends on precise auditory and echolocation systems. Therefore, disease processes affecting these systems, including parasitic infections pose significant morbidity and may result in stranding and death. Here, we describe the pathologic and parasitological findings in an adult, male melon-headed whale ( Peponocephala electra ) stranded dead on the Brazilian coast. The...
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...
Unveiling the Viral Landscape in Gastric CancerNARA Subscribed
The present study aimed to comprehensively characterize the cancer-associated virome in patients with gastric cancer. A total of 452 samples were analyzed, including 226 tumor tissues and 202 peritumoral tissues from patients undergoing surgical resection, alongside 24 normal gastric mucosa samples obtained via endoscopy from individuals without cancer. RNA was extracted, libraries were prepared, and paired-end sequencing was...
Application and Residual Effect of Phosphorus and Silicon in Tropical Soils: Influence on Nutrient Accumulation in Rainfed RiceNARA Subscribed
Rice is essential for global food security. However, the effects of phosphorus (P) and silicon (Si) interaction on macronutrient accumulation in rice grown in tropical soils remain poorly understood, particularly regarding the persistence of these effects in subsequent crops. This study aimed to investigate the combined influence of Si and P levels on the accumulation of macronutrients (N, P, K, Ca, Mg, and S) and Si in the sh...
Decoupling bioaccumulation and trophic transfer: nanoatrazine accumulates in microalgae but shows limited transfer to zooplanktonNARA Subscribed
Nanoformulations of pesticides have been proposed as a strategy to improve agricultural efficiency while potentially reducing environmental contamination. However, little is known about the bioaccumulation and trophic transfer of nanopesticides in aquatic food webs. In this study, the bioaccumulation of poly(ε-caprolactone)-encapsulated nanoatrazine (nATZ-PCL) was evaluated in the microalga Raphidocelis subcapitata , as well a...
