Descriptive study of intestinal parasites in a municipality of the western Braz...

Intestinal parasites are among the most prevalent infections in humans. A cross-sectional survey was performed in a Canutama, Amazonas state, Brazil, in order to estimate the prevalence of intestinal parasites. The detection of parasites in the feces was performed using the Lutz method. Demographic data and the characteristics of the households were collected using a questionnaire. The prevalence of parasites w...

Visceral leishmaniasis among Indians of the State of Roraima, Brazil. Clinical ...

A description of the epidemiological profile of visceral leishmaniasis among Indians in the State of Roraima, Brazil, was based on the clinical characteristics of human and dog disease, ecological aspects of the area where the cases occurred and entomologic investigations performed from 1989 to 1993. The 82 human cases were reported in six out of eight Counties that existed then in the State; there was a 69.5% ...

Leishmania (Viannia) naiffi : rare enough to be neglected?

In the Brazilian Amazon, American tegumentary leishmaniasis (ATL) is endemic and presents a wide spectrum of clinical manifestations due, in part, to the circulation of at least seven Leishmaniaspecies. Few reports of Leishmania (Viannia) naiffiinfection suggest that its occurrence is uncommon and the reported cases present a benign clinical course and a good response to treatment. This study aimed to strengthe...

Polymerase chain reaction-based method for the identification of Leishmania (Vi...

Introduction: in the Americas, mucosal leishmaniasis is primarily associated with infection by Leishmania (Viannia) braziliensis. However, Leishmania (Viannia) guyanensis is another important cause of this disease in the Brazilian Amazon. In this study, we aimed at detecting Leishmaniadeoxyribonucleic acid (DNA) within paraffin-embedded fragments of mucosal tissues, and characterizing the infecting parasite spe...

This study evaluated the occurrence of American tegumentary leishmaniasis (ATL) in the State of Amazonas, Brazil, in the last 30 years with emphasis on the last 10 years (2001 to 2010). The disease was predominantly observed in males (76.2%), in the 21- to 30-year-old age group (26.6%) and in extractive workers (43.7%); 3.3% of the cases were the mucosal form. The endemic channel shows the disease seasonality, ...

Trypanosoma cruzi I and IV stocks from Brazilian Amazon are divergent in terms ...

Background: In the Brazilian Amazon, clinical and epidemiological frameworks of Chagas disease are very dissimilar in relation to the endemic classical areas of transmission, possibly due to genetic and biological characteristics of the circulating Trypanosoma cruzi stocks. Twenty six T. cruzi stocks from Western Amazon Region attributed to the TcI and TcIV DTUs were comparatively studied in Swiss mice to test ...
