Introduction The distal interphalangeal joint (DIPJ) plays a crucial role in the function of the hoof and digit. Dislocations and subluxations in this region are rare and primarily of traumatic origin. Case Report This case report aims to describe two unusual cases of open DIPJ dislocation, including clinical presentation, diagnostic workup, treatment, and long-term follow-up. Both animals presented with open traumatic distal...

Research on cephalopod early ontogeny has significantly advanced in recent decades, including embryo organogenesis and neurogenesis and early behavioural adaptations, particularly in commercially important and coastal species. Within this context, here we compiled current knowledge on the collection, handling and care under experimental conditions and monitoring in the field of cephalopod eggs and egg masses. It covers field o...

Multidrug-resistant (MDR) Klebsiella pneumoniae , particularly high-risk clones such as sequence type (ST) 147, have been increasingly reported worldwide. However, data on their occurrence in reproductive disorders of companion animals remain limited. This study describes, for the first time, an extended-spectrum β-lactamase (ESBL)-producing K. pneumoniae ST147 isolated from a canine paraprostatic abscess. The isolate (UNISA-D...

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...

Background Chronic inflammatory pain is associated with persistent sensory and immune dysregulation. We evaluated the therapeutic efficacy of two cannabinoids formulations—Cannabigerol (CBG) and Standardized Full-Spectrum Cannabis Extract (FULL) in a preclinical model of acute and Chronic inflammatory pain and examined their effects on peripheral and central inflammatory mediators. Methods Cannabinoid analgesic effects were as...

Four Alismataceae names from the Americas are investigated. Second‐step lectotypes are designated for Hydrocleys martii and Sagittaria seubertiana according to the Art. 9.17 of Madrid Code . A lectotype is designated for Sagittaria isoetiformis , resolving a 130‐year nomenclatural ambiguity. Finally, the previously proposed neotypification for Sagittaria chilensis was superseded since the discovery of original materials at HAL...

The American manatee ( Trichechus manatus ) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater. We applied MaxEnt modeling to presence‐only data (sightings and filtered telemetry records) to p...

Aim Elevational gradients are excellent systems to study biodiversity variation, yet the ecosystem functions performed by animals along these gradients are poorly understood. We assessed tropical elevational patterns of ant‐mediated seed removal, insect predation and the phylogenetic diversity of the local ant assemblages performing these functions as well as the effects of climate and productivity. Location Southeast Brazil,...

Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...
