Hemogregarines in bufonid anurans from the Brazilian Amazon, with description a new species of (Apicomplexa: Lankesterellidae).

Here we describe, in an unprecedented way for the Brazilian Amazon, one Apicomplexa species infecting an anuran in Pará, Brazil, using an integrative approach that includes taxonomy, providing morphology, morphometrics, and molecular data. Samples were collected between February 2021 and February 2022 in the community of Curupira, municipality of Santarém, and in the industrial area of Marabá, both in Pará state. Specimens of and were captured by hand during the active search, and blood samples were collected by cardiac puncture.

Toxic and essential elements determination in edible tissues of different elasmobranch species from Southeastern Brazil and potential human health risks.

Brazil is the largest consumer of shark meat, which is sold by fishmongers under the umbrella term cação. The population consumes this meat due to its low cost and lack of fish bones. In this work, morphometric measurements and metal/metalloid concentration (As, Hg, and Se) were assessed in the muscle tissue of species from Dasyatis spp.

Molecular Detection of Trypanosomatids in Rodents and Marsupials in the State of Amapá, Brazil.

Trypanosomatids of the genera and are parasites of medical and veterinary importance that infect mammals, including humans and domestic and wild animals. Among mammals, rodents and marsupials play a crucial role in maintaining and spreading the zoonotic transmission cycle of these parasites. The present study aimed to detect the natural occurrence of spp.

Bioaccumulation of Metals in Fish Collected from Macapá Urban Aquatic Environments (Brazilian Amazon) and the Risks to Human Health.

Macapá City, located in the Brazilian Amazon, faces critical aquatic pollution challenges due to inadequate sanitation infrastructure, leading to metal contamination in fish within its urban water bodies. Our study evaluated the concentrations of metals (Cu, Cd, Cr, Fe, Mn, Ni, Pb, Zn, and Hg) in muscle tissues of fish from igarapés, ressaca areas, and canals. Samples were collected from six sampling sites to investigate the bioaccumulation of these metals and their potential human health risks.

Adverse Reactions to Cosmetic Fillers in the Oral and Maxillofacial Region: Clinico-Pathological, Histochemical, and Immunohistochemical Characterization.

Background: Cosmetic injections are increasing, as their complications, which can be misdiagnosed as neoplastic lesions. This study aimed to detail clinical, pathological, histochemical, and immunohistochemical features of adverse reactions to cosmetic fillers in the oral and maxillofacial region.

Methods: Samples were retrieved from five pathology laboratories.
