The interest in nutritional strategies that may counteract the deleterious oxidative effects induced by strenuous exercises is remarkable. Herein, the impact of white tea () (WT), a polyphenol-rich beverage, on antioxidant status in endurance-trained rats after one session of exhaustive exercise were evaluated. Male Wistar rats were divided into groups, which received: control groups - water, and testing groups - WT1 (0.

Human infections with gut protozoan parasites are neglected and not targeted by specific control initiatives, leading to a knowledge gap concerning their regional diversity and epidemiology. The present study aims to explore Giardia duodenalis genetic diversity and assess the epidemiologic scenario of subclinical infections in different Brazilian biogeographic regions. Cross-sectional surveys (n = 1334 subjects) were conducted in four municipalities in order to obtain fecal samples and socioenvironmental data.

Metastrongylosis is an infection of the respiratory tract of pigs caused by parasites of the genus , whose eggs are similar to other through light microscopy; species-specific identification can be performed with molecular tools. We explored the species composition and the genetic diversity of infecting pigs in close contact with humans in impoverished rural communities in the state of Piauí, in northeastern Brazil. Fecal samples ( = 78) were collected for parasitologic tests.

Background: This study assessed the interactions between income, nutritional status and intestinal parasitism in children in Brazil.

Methods: A cross-sectional study (n = 421 children aged 1 to 14 years living in the states of Piauí (rural communities in the city of Teresina) and Rio de Janeiro (rural and periurban communities in the city of Cachoeiras de Macacu) was performed in order to obtain income and anthropometric data, as well as fecal samples for parasitological analyses through the Ritchie technique.

Results: Children infected with Ascaris lumbricoides had significantly lower means of height-for-age z scores (- 1.

Article Synopsis
  • The study investigates the diversity, relationships, and distribution of Entamoeba species, which impact human health, across various Brazilian ecosystems.
  • Researchers collected and analyzed fecal samples from multiple communities, identifying four species and establishing their prevalence, particularly noting higher positivity in children aged 6-10 years.
  • Findings reveal significant interspecific diversity among Entamoeba spp., with specific subtypes prevalent in certain biomes, and highlight that E. histolytica was only found in the Amazon.

Soil-transmitted helminthiasis (STHs) are poverty-related diseases with high prevalence rates in developing countries. The present study aims to describe the epidemiological scenario of STHs in an urban population in the Brazilian Amazon. A cross-sectional survey ( = 349 children aged 1-15 years) was carried out to obtain faecal samples and sociodemographic and sanitation data.

Background: In northeastern Brazil, the wild nature of Trypanosoma cruzi vectors has challenged control actions. This study aims to describe the entomological and epidemiological scenario of Chagas disease in rural communities in the state of Piauí.

Methods: A cross-sectional study (n=683 individuals/244 dwellings) was carried out to obtain serum samples, sociodemographic data and intra- and peridomestic triatomines.

In this study, we assessed the genetic diversity of Ascaris lumbricoides / Ascaris suum circulating in humans and pigs, exploring potential zoonotic cycles in endemic areas in Brazil. We carried out cross-sectional surveys in four municipalities: Santa Isabel do Rio Negro (SIRN-AM) (n = 328); Nossa Senhora de Nazaré (NSN-PI) and Teresina (TER-PI) (n = 605 and n = 297, respectively); and Cachoeiras de Macacu (CAM-RJ) (n = 543). We also studied 61 fecal samples/adult worms obtained from pigs (n = 53 in NSN-PI and n = 8 in TER-PI).

Article Synopsis
  • The study investigated the occurrence and characteristics of various Entamoeba infections, including E. histolytica and E. dispar, among 213 subjects using fecal sample analysis and PCR methods.
  • The overall prevalence of infection was found to be 10.3%, with higher rates in individuals consuming rainwater and those practicing open defecation.
  • The research highlighted that most identified infections were asymptomatic, pointing to significant sanitary issues in the region that facilitate transmission of these parasites.
