Ureaplasma diversum is an opportunistic bovine pathogen associated with reproductive disorders, including infertility, granular vulvovaginitis, placentitis, and abortion; however, detailed descriptions of fetal osteoarticular lesions remain exceptionally uncommon. This report describes the gross, histopathological, and molecular findings of a bovine abortion associated with U. diversum infection presenting with concurrent pulm...

Rays of the family Rhinopteridae Jordan & Evermann, 1896 are highly migratory and widely distributed in warm tropical and temperate waters. Along the Brazilian coast, the presence of two species has been recorded: Rhinoptera bonasus Mitchill, 1815 and Rhinoptera brasiliensis Müller, 1836. These stingrays are commonly caught as bycatch in trawl fisheries, however, the two species lack distinctive external morphological features...

Background Bovine mastitis is the most economically significantdisease in dairy farming, with Staphylococcus aureus and Staphylococcus chromogenes asprominent agents, the former posing a major threat. As principal immune sentinels in themammary gland, macrophages orchestrate early pathogen recognition and immune activation,critically influencing the trajectory and outcome of infection. Thus, this study aimed tocharacterize the...

In this study, we conducted an epidemiological investigation and analyzed the agreement between the Faust technique and the immunochromatographic assay in the diagnosis of Giardia spp. in 272 cats in the municipality of Londrina, Paraná state, Brazil. We identified an overall prevalence of 74.63% (203/272 [95% CI: 69.14–79.44%]) of Giardia spp. in cats, being significantly higher in adult and non-domiciled animals, which prese...

Anthropogenic habitat transformation has led to population declines and increasing isolation of populations of many species, particularly top predators, where small and fragmented populations often experience limited dispersal and reduced genetic diversity. Jaguars ( Panthera onca ), for example, have lost half of their historical range and most populations outside the Amazon biome are small, isolated and highly threatened. He...

Tumor progression depends on an adequate blood supply to sustain oxygen and nutrients delivery. While tumor angiogenesis involves the formation of new blood vessels from pre-existing ones, vessel co-option represents a non-angiogenic vascularization strategy whereby tumor cells utilize pre-existing host vessels. Co-opted vessels have been considered refractory to anti-angiogenic therapies, and pharmacological modulation of co-...

Rapid warming across Antarctica is reshaping terrestrial ecosystems, yet the dynamics of macroscopic fungi in this region remain largely undocumented. Here, we present the first ecological and statistical assessment of Agaricales fungi on Byers Peninsula, Livingston Island (South Shetland Islands, Antarctica), based on surveys conducted in February 2023. Across 20 sites, we recorded 2,566 basidiomes representing eight morphosp...

Based on the evaluation of 3,902 local floristic references published between 2005 and 2025, an update to the floristic knowledge map of Italy is presented. To measure the progress in floristic knowledge across Italy’s administrative regions, the ‘Index of Floristic Knowledge Advancement’ (IFA) is proposed here. This index categorizes regions based on the proportion of potential improvement that has actually been achieved. Res...

Climate change is increasing constraints on crop production and reinforcing the need for sustainable alternatives to chemical disease control. Sorghum is a drought-tolerant crop of increasing importance. However, anthracnose caused by Colletotrichum sublineola remains its most destructive disease, and no biological control products are currently registered for its management. This study evaluated bacterial isolates as potentia...

Piscirickettsiosis (SRS) remains the main infectious disease affecting salmon aquaculture in Chile. This study evaluated expert perceptions of the effectiveness of SRS control measures and the level of agreement among industry professionals. A structured cross‐sectional expert‐elicitation survey was conducted with nine head fish health managers representing more than half of the Chilean Atlantic salmon and rainbow trout produc...

Purpose: Recent studies highlight the potential of silicon (Si) and titanium (Ti) nanoparticles (NPs) in agriculture, particularly for foliar application. This study aimed to evaluate the effects of foliar-applied Si and Ti NPs on biometric parameters, chlorophyll content, and nutrient uptake by maize. Methods: The experiment was conducted in a completely randomized design with four replications. Concentration of 0, 50, 100, a...
