Angiostrongylus vasorum is a metastrongylid nematode that parasitizes the pulmonary arteries and right heart of canids, being the etiological agent of canine angiostrongylosis, a disease of growing veterinary concern due to its expanding geographic distribution and the involvement of domestic and wild hosts. In Brazil, the parasite has been reported mainly in domestic dogs and some wild canids, and its occurrence in mustelids...

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...

Organotellurium (OTe) compounds have pharmacological properties, including leishmanicidal, antimalarial, and antifungal activities. Herein, we assessed cytotoxicity effects of OTe RF07 in a panel of tumor cell lines, as well as its oxidative, toxicity, and hemolytic actions. The toxicity was evaluated on Allium cepa and Artemia salina larvae. Cell viability was also assessed by resazurin in murine cells (Sarcoma 180), human ce...

Bromeliaceae exhibits significant pollen diversity. Within the family, pollen grains are dispersed either as monads or tetrads and may be monosulcate, bi-, tri-, tetra-, or pantoporate, or even inaperturate. Ornamentation includes reticulate, foveolate, microreticulate, perforate, or psilate patterns. Additional variations are observed in the margins of the apertures and in the exine deposition on the aperture membrane. In gen...

This study aimed to enhance surfactin production in Bacillus subtilis by replacing the native promoter of the surfactin synthase operon (P srfA ) with the strong IPTG-inducible promoter Pgrac to address challenges in large-scale biosurfactant production. The engineered strain was developed through homologous recombination, creating an integration cassette fused via overlap extension PCR and transformed into B. subtilis RI4914....

Schistosomiasis is an acute and chronic illness caused by parasites of the genus Schistosoma . It is present in 79 countries worldwide and primarily affects socioeconomically vulnerable populations due to exposure to infested water during daily activities. Praziquantel is the primary drug used in international schistosomiasis treatment. However, adverse effects and parasite resistance mechanisms have been reported, ranging fro...

Bird collisions with transmission lines (TLs) cause significant bird mortality worldwide, yet technological solutions targeting this infrastructure remain critically underdeveloped. This systematic review synthesizes 58 peer-reviewed articles and 86 patents on bird detection and collision mitigation technologies for TL infrastructure, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 202...

Otolith microchemistry analysis revealed that bycatch of European shads, allis shad Alosa alosa and twaite shad Alosa fallax , in western Iberian commercial fisheries removes individuals from a wide array of natal origins, with the most abundant source rivers suffering the heaviest losses. Spatial variation in bycatch risk was evident: Specific marine areas exhibited high natal origin diversity, reflecting complex dispersal. A...
