13. High prevalence of norovirus in children with sporadic acute gastroenteritis in Manaus, Amazon Region, northern Brazil
BACKGROUND Norovirus (NoV) is a major cause of acute gastroenteritis (AGE) worldwide, especially in children under five years. Studies involving the detection and molecular characterisation of NoV have been performed in Brazil, demonstrating its importance as an etiological agent of AGE. OBJECTIVES The objectives of this study were to investigate the fre

17. Relationship of Helicobacter pylori seroprevalence with the occurrence and severity of psoriasis
Abstract: BACKGROUND: Psoriasis is a chronic inflammatory disease that affects the skin and joints and has a multifactorial etiology. Recently, it has been suggested that Helicobacter pylori infection may contribute as a trigger for the development of the disease. OBJECTIVES: To determine the prevalence of H. pylori seropositivity in patients with psoriasi

18. SEROPREVALENCE OF HTLV IN A POPULATION OF HIV1-INFECTED PATIENTS IN MIDWESTERN BRAZIL
SUMMARY Human T-cell lymphotropic virus (HTLV) may affect the clinical course of human immunodeficiency virus 1 (HIV1). Both infections are common in endemic areas because these viruses share similar routes of transmission. The aim of this study was to estimate the seroprevalence of HTLV1/2 in a population of HIV1-infected patients in the state of Goiás, Mi

20. Hepatitis E virus seroprevalence among schistosomiasis patients in Northeastern Brazil
Abstract Background Hepatitis E virus (HEV) can cause chronic infection with rapid progression to liver cirrhosis in immunocompromised patients. HEV seroprevalence in patients with Schistosoma mansoni in Brazil is unknown. We evaluated the prevalence of past or present HEV infection in schistosomiasis patients in Recife, Pernambuco, Brazil. A total of 80 pa

23. Diagnostic methods to cutaneous leishmaniasis detection in domestic dogs and cats
Abstract: Cutaneous leishmaniasis is caused by different species of Leishmania. In domestic animals such as dogs and cats, the diagnostic consists of clinical, epidemiological and serological tests, which changes among countries all around the world. Because of this diversity in the methods selected, we propose this systematic literature review to identify t

24. Evaluation of a recombinant rhoptry protein 2 enzyme-linked immunoassay for the diagnosis of toxoplasmosis acquired during pregnancy
The aim of this study was to evaluate an enzyme-linked immunoassay with recombinant rhoptry protein 2 (ELISA-rROP2) for its ability to detectToxoplasma gondii ROP2-specific IgG in samples from pregnant women. The study included 236 samples that were divided into groups according to serological screening profiles for toxoplasmosis: unexposed (n = 65), probabl
