While bats are known to harbor various viruses and bacteria, their role as hosts for hemoparasites has not been extensively studied. This research investigated the presence of ectoparasites and vector-borne pathogens—including Anaplasmataceae agents, hemoplasmas, apicomplexans, and kinetoplastids—in 74 Phyllostomidae bats sampled from an urban forest fragment in southeastern Brazil. Overall, 31.1% of the bats were infested wit...

Ring chromosomes (RCs) are rare structural variants usually formed by fusion of both chromosome arm extremities, frequently associated with terminal deletions. RCs are investigated through karyotype, fluorescence in situ hybridization, chromosomal microarray analysis, and, more recently, optical genome mapping (OGM), which enables genome-wide structural variant detection; however, its accuracy depends on alignment to a referen...

Down syndrome (DS), or trisomy 21 (T21), represents the most common genetic cause of intellectual disability worldwide and is associated with a wide range of medical, developmental, and neurodegenerative conditions, including a universal predisposition to early-onset Alzheimer’s disease (AD). Since its establishment in 2014, the Trisomy 21 Research Society (T21RS) has provided a global forum for advancing DS research across di...

Monitoring the health of cattle herds is essential for establishing prophylactic measures and reducing their impact on the production chain, especially in regions where beef cattle form the economic base. This study aimed to determine the serological profile of infectious bovine rhinotracheitis (IBR), bovine viral diarrhea (BVD), leptospirosis, toxoplasmosis, and neosporosis in beef cattle slaughtered in a federally inspected...
