The emergence and persistence of plasmid-mediated polymyxin resistance in Brazilian poultry production pose a significant One Health challenge. Here, cloacal swabs from 202 broilers across four farms in the State of Rio de Janeiro yielded 125 Enterobacteriaceae isolates growing on polymyxin-EMB agar. Escherichia coli accounted for 99% of resistant isolates, with one Klebsiella pneumoniae . Multidrug resistance (MDR) was observ...

Megninia ginglymura (Mégnin, 1877) (Acariformes: Analgoidea: Analgidae) is a common feather mite of laying hens and a potential contributor to plumage damage and reduced productivity, yet its population dynamics and microhabitat use remain insufficiently characterized under modern commercial conditions. We conducted a year-long assessment of M. ginglymura abundance and intra-host distribution across three major production syst...

Assessing species richness (i.e., the number of species in a specific area) is of significant ecological relevance across theoretical, empirical, and practical applications. Accurately estimating species richness remains a persistent statistical challenge, as direct species counts are often unreliable. Consequently, numerous species richness estimation methods have been developed to accommodate a wide range of data types, rese...

Momordica charantia is a climbing plant popularly known as melon-de-São-Caetano, erva-de-São-Vicente, fruit-de-snake, melonzinho and gourd-de-São-Caetano. Its traditional use in folk medicine, associated with a wide range of therapeutic effects—such as antioxidant, anthelmintic, anti-inflammatory, antifungal, gastroprotective, hepatoprotective and antihyperglycemic activities—has aroused scientific interest and motivated the p...

Frontotemporal dementia (FTD) is a neurodegenerative disease characterized by significant clinical and genetic heterogeneity, with approximately 40% of cases linked to hereditary genetic mutations, including MAPT , GRN , and C9ORF72 . Recently, microRNAs (miRNAs) have emerged as key regulators of cellular processes related to neurodegeneration and as potential biomarkers for FTD. However, their relevance in presymptomatic stag...

Insects, belonging to the phylum Arthropoda, play essential roles in ecosystems, play essential roles in ecosystems, such as pollination, pest control, and decomposition. However, some species are vectors of diseases, which makes the development of control methods crucial. The use of synthetic insecticides, although effective, causes serious environmental and health problems. As an alternative, plant essential oils, which are...
