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...

Background Mycobacterium bovis BCG is widely used as a vaccine vector due to its safety, genetic stability, and immunomodulatory properties. However, current expression systems for BCG transformation rely on antibiotic resistance genes, raising biosafety concerns. Therefore, alternative strategies—such as the use of auxotrophic strains—are highly desirable. Our group previously employed BioBrick™ technology to construct the pU...

Ceratocystis paradoxa is a polyphagous, soil-borne pathogen that threatens various crops worldwide. This study evaluated soil suppressiveness against C. paradoxa and identified key biotic and abiotic factors involved. Suppressiveness was assessed using banana peel baits, followed by comparative analysis of microbial communities and soil physicochemical properties in five suppressive and five conducive soils. Suppressive soils...

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...

Arboreal primates rely heavily on acoustic communication, making them ideal candidates for passive acoustic monitoring (PAM). Here, we investigated the detectability of vocalisations from Alouatta belzebul , Callithrix jacchus , Saimiri spp, and Sapajus flavius in three fragments of Atlantic Forest and two fragments of Caatinga Forest in northeastern Brazil. We recorded each area for 48 h per month over 7 months, placing one a...

Collembola are minute, wingless hexapods that occur in nearly all terrestrial ecosystems and playing a fundamental role in soil functioning and global carbon cycling. The taxonomy within the family Isotomidae is unclear due to the strong morphological similarity among species, low interspecific variability, and overlapping chaetotaxic patterns that often obscure species boundaries. These challenges highlight the need for stand...

The co-processing of waste in clinker synthesis is a widely adopted strategy to reduce the consumption of fossil fuels and natural raw materials. However, the incineration of waste may increase the release of potentially toxic compounds (PTCs) and volatile metals, raising concerns for the environment and human health. A major limitation in assessing these risks is the lack of suitable methods to directly quantify PTCs in anhyd...
