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...

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...

Canine cutaneous mast cell tumor (cMCT) is one of the most common skin neoplasms in dogs, with lymph nodes representing the primary route of metastasis. Accurate sentinel lymph node (SLN) identification is therefore essential for staging and treatment planning. This study evaluated indirect lipiodol lymphography (IL) and intraoperative methylene blue (MB) mapping in 21 dogs, including 26 tumors and 38 excised lymph nodes, to a...

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...

Lead pollution is a major environmental concern, but current decontamination technologies remain limited due to high costs. Therefore, alternative biotechnological processes have been successfully developed and applied due to their reduced cost and lower aggressiveness in the environment. The remarkable adaptive versatility of Chromobacterium violaceum in metal-contaminated environments makes this bacterium a promising candida...

Chikungunya virus (CHIKV) is an arthropod-borne virus responsible for an acute febrile illness characterized by severe polyarthralgia, predominantly affecting peripheral joints. In a substantial proportion of patients, these symptoms may progress to chronic manifestations that significantly impair quality of life. Animal models are therefore critical for the development of effective therapeutic and preventive strategies, inclu...

Background and aims Sustainable citrus production requires nitrogen (N) management strategies that account for soil–plant nutrient interactions, particularly those affecting calcium (Ca) nutrition. In fertigated citrus orchards, strategies differing in NO₃⁻:NH₄⁺ balance and associated Ca supply affect soil chemical properties, plant nutritional status, fruit yield, and NUE. This study evaluated the effects of contrasting ferti...

Remote sensing has become a strategic tool for monitoring irrigation systems, especially in regions with a lack of local agroclimatic and field-scale management data. This study evaluated the water productivity and irrigation performance of soybean cultivation in Pratânia, in the midwestern region of São Paulo State, Brazil, comparing a center pivot system (72.77 ha) and three rainfed areas (with an area of 53.74 ha) over thre...

Introduction Male hypogonadism, including age-related and functional forms, is characterized by insufficient testosterone production often associated with obesity and metabolic comorbidities. Testosterone replacement therapy (TRT) increases serum testosterone but suppresses spermatogenesis and may cause adverse effects. Selective estrogen receptor modulators (SERMs), such as clomiphene citrate, have emerged as an alternative a...

Sperm subpopulations are distinct cell clusters that define sperm function and serve as biomarkers for optimizing donor selection and reproductive success in seasonally breeding species. Male squirrel monkeys ( Saimiri collinsi , an Amazonian primate), exhibit marked seasonal reproduction linked to the fattening phenomenon, an androgen-dependent weight gain coinciding with the mating season. We investigated sperm subpopulation...
