Capybara ( Hydrochoerus hydrochaeris ), the largest rodent in the world, are animals native to Brazil that are increasingly adapting to urban environments, which raises concerns for One Health, including the risk of zoonotic diseases such as Brazilian Spotted Fever. Moreover, increased interaction between humans and capybaras can lead to accidents involving injuries and infections. This study aimed to characterize the oral mic...

The increasing resistance of Pseudomonas aeruginosa to carbapenem antibiotics is shifting the landscape of high-risk clones from a strictly hospital-acquired threat to a global pathogen with One Health relevance. Given the limited therapeutic options available, developing new treatments is essential. We previously reported the complete genome sequence of φSPM-1 phage from the family Myoviridae . In this study, we show that φSP...

The aim of the present study was to evaluate the effects of dietary supplementation with the microalgae Nannochloropsis oculata and Phaeodactylum tricornutum , either separately or in combination, on growth performance, lipid profile, haematoimmunological parameters, and resistance to Edwardsiella tarda infection in Nile tilapia ( Oreochromis niloticus ). A total of 960 juvenile Nile tilapia (2.87 ± 0.68 g and 5.65 ± 0.16 cm)...

Human T-lymphotropic virus type 1 (HTLV-1) infection is associated with a broad spectrum of neurological manifestations, including conditions that may precede the development of HTLV-1–associated myelopathy/tropical spastic paraparesis (HAM/TSP). This analytical, descriptive cross-sectional study aimed to estimate the prevalence of HTLV-1 infection and describe associated sociodemographic, socioeconomic, behavioral, and clinic...

This study evaluated the effect of N-acetylcysteine ​​on oxidative biochemistry and bone damage during the development of ligature-induced experimental periodontitis in rats. The rats were divided into three groups (n = 8/group): control, experimental periodontitis (EP), or experimental periodontitis plus daily N-acetylcysteine administration (EP + NA) (100 mg/kg/day). Periodontitis was induced by bilateral silk ligatures on t...

Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We sampled arachnids at 120 sites using active search and litter sifting. Native vegetation cover was quantified...

Kefir is a beverage obtained by fermenting milk or sugary solutions with a symbiotic community of bacteria and yeasts, presenting promising antimicrobial, antioxidant, and immunomodulatory properties. This systematic review aimed to synthesize evidence from preclinical studies evaluating the effects of kefir or its by-products on biomarkers of inflammation, oxidative stress, and gut health in animal models of IBD. A systematic...

Circoviruses (CVs) infect diverse mammals, birds, and freshwater fish and are linked to diseases causing major economic losses. Despite being well studied in psittacines, their circulation in other avian groups and mammals is poorly understood. We conducted molecular surveillance of CVs in migratory birds and mammals along the Paraná coast, southern Brazil. Sterna hirundinacea specimen tested positive by Nested-PCR for GullCV....

The commerce of decorative dried plants from the Brazilian Cerrado Biome provides cultural transmission, and essential revenue for low-income families. We investigated this production value chain over the past decade, assessing its economic and social relevance and mapping the main actors involved, and characterizing the interviewed participants, as well as the foreign trade trends over 50 years. Data was gathered through inte...
