Visceral leishmaniasis (VL) is an endemic parasitic disease frequently found in Northeast Brazil and may cause acute kidney injury (AKI) and glomerulonephritis. After appropriate treatment, renal function recovery may occur. We describe the rare case of a patient with VL, who developed severe AKI requiring dialysis and was subsequently diagnosed with Chagas disease coinfection. After specific treatment for VL, there was partial recovery of the renal function, followed by the onset of Chagas disease cardiomyopathy.

Background: Determining esophageal and colon involvement in patients with Chagas disease occurs through invasive and uncomfortable examinations, which in most cases are not performed. The objective of this study was to assess the involvement of anti-M2-pyruvate kinase (M2-PK) autoantibodies in the development of digestive alterations and/or in the diagnosis of the digestive form of human Chagas disease.
Methods: The total IgG and isotype (IgG1, IgG2, IgG3, IgG4) production was quantified using the antigen of Trypanosoma cruzi and the human M2-PK recombinant protein via the ELISA technique.

Background: Trypanosoma cruzi is a protozoan parasite which causes Chagas disease. Mother-to-child transmission is the main route of transmission in vector-free areas. Congenital Chagas disease refers specifically to cases arising from this route of transmission.

Rapid urbanization and migration in Latin America have intensified exposure to insect-borne diseases. Malaria, Chagas disease, yellow fever, and leishmaniasis have historically afflicted the region, while dengue, chikungunya, and Zika have been described and expanded more recently. The increased presence of synanthropic vector species and spread into previously unaffected areas due to urbanization and climate warming have intensified pathogen transmission risks.

Paracoccidioides are dimorphic fungal pathogens and the etiological agents of paracoccidioidomycosis (PCM). This severe systemic mycosis is restricted to Latin America, where it has been historically endemic. Currently, PCM presents the fewest diagnostic tools available when compared to other endemic mycoses.

This study aimed to investigate the dissemination of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in water samples obtained during the coronavirus disease 2019 pandemic period, employing cross-assembly phage (crAssphage) as a fecal contamination biomarker and next-generation sequencing protocols to characterize SARS-CoV-2 variants. Raw wastewater and surface water (stream and sea) samples were collected for over a month in Rio de Janeiro, Brazil. Ultracentrifugation and negatively charged membrane filtration were employed for viral concentration of the wastewater and surface water samples, respectively.
