Rhodococcus equi is an important bacterium that affects foals up to six months of age, especially those that are immunocompromised. The main manifestation is pyogranulomatous pneumonia; nevertheless, extrapulmonary lesions have not only been reported, but are not uncommon, including arthritis and osteomyelitis. Despite the widespread occurrence of rhodococcosis, the macro- and microscopic lesions in the musculoskeletal system...

Tropical forests, particularly the Atlantic Forest, are among the most biodiverse and threatened ecosystems on Earth. Intense fragmentation, historical deforestation, and climate change have compromised their integrity and endangered endemic and rare species. The situation is even more critical in the Doce River Basin (DRB), a biodiversity hotspot in southeastern Brazil, due to the expansion of pastureland and mining, as well...

Aggregate dwellings are a common construction configuration in urban environments in the Americas, where space constraints favour terraced construction. However, seismic interaction between adjacent dwellings can significantly alter their structural response, especially when there are differences in height or in the stiffness of horizontal diaphragms. Despite advances in the seismic analysis of masonry buildings, most previous...

Meloidogyne incognita is one of the main phytonematodes affecting cotton productivity, requiring sustainable control alternatives to chemical nematicides. This study evaluated the efficacy of different bioinputs based on Bacillus velezensis BEIB-46 for the biological control of M. incognita and their effects on cotton development. The strain was identified through high-resolution genomic analyses, followed by production via su...

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...

Kelp forests are among the most extensive and productive coastal ecosystems, yet they remain underrepresented in global conservation policy despite widespread declines driven by interacting global- (i.e., ocean warming, marine heatwaves) to local-scale stressors. At the same time, kelp conservation and restoration efforts are expanding rapidly across regions, but measures of success and syntheses tend to primarily focus on eco...

Purpose Systematic collection and analysis of antimicrobial resistance data from key bacterial pathogens is essential to contribute to control antimicrobial resistance (AMR). The aim of this work was to survey the drug resistance on clinically relevant organisms stratified according to age, gender, clinical specimens and facilities. Methods Microbiological data were collected from 55 centers across 24 states in Mexico between...

In the Eastern South Pacific (ESP), blue whale ( Balaenoptera musculus subsp.) aggregations have been described for two feeding areas (in northern and southern Chile) and in the Eastern Tropical Pacific (ETP). However, despite the knowledge of these areas, little is known about the seasonal movements of blue whales between them. Comparisons of 1074 individual blue whales, photographed across these regions from 1992 to 2019, re...

Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray ( Dasyatis hypostigma ), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean. Ages were estimated from vertebral centra, including 201 males and 71 females, with sizes varying...

Morphine is widely used as an analgesic in vertebrates, yet its cardiorespiratory safety and effective therapeutic range remain poorly explored in fish. This study investigated the dose-dependent effects of morphine on cardiac and respiratory parameters of juvenile tambaqui (Colossoma macropomum). Juveniles (25.95 ± 4.08 g) were randomly assigned to control, sham (0.9% saline) or morphine groups (24, 28, 32, 36 and 40 mg kg−1,...
