13. Diagnostic utility of an immunochromatography test for the detection of Leptospira IgM antibodies in domestic dogs
ABSTRACT: A cross-sectional study using 99 serum samples of dogs from southern Chile was conducted to determine the diagnostic utility of a rapid immunochromatography assay for the detection of Leptospira specific IgM antibodies as screening test and as a potential aid in the diagnosis of leptospirosis in animals with and without clinical suspicion of the di

14. The performance of serological tests for Leishmania infantum infection screening in dogs depends on the prevalence of the disease
ABSTRACT Dogs are considered the main reservoir of Leishmania infantum. This protozoan causes visceral leishmaniasis (VL), an uncontrolled urban zoonosis in Brazil. Serological tests and polymerase chain reaction (PCR) on peripheral blood were performed to identify infected dogs in scenarios of higher and lower prevalence of the disease (Teresina and Vitóri

15. Comparative performances of serologic and molecular assays for detecting human T lymphotropic virus type 1 and type 2 (HTLV-1 and HTLV-2) in patients infected with human immunodeficiency virus type 1 (HIV-1)
ABSTRACT The present study evaluated several techniques currently available (commercial kits and in-house assays) for diagnosing human T lymphotropic viruses types 1 and 2 in two groups of patients enrolled at HIV/AIDS specialized care services in São Paulo: Group 1 (G1), n = 1608, 1237 male/371 female, median age 44.3 years old, majority using highly activ

16. Standardization and validation of Dot-ELISA assay for Paracoccidioides brasiliensis antibody detection
Abstract Background Paracoccidioidomycosis (PCM) is a neglected systemic mycosis caused by a dimorphic fungus of the Paracoccidioides genus. The standard diagnosis is based on isolation of the fungi in culture, and by microscopic visualization of characteristic multiple budding yeast cells in biological samples. However, in some situations, access to the s

17. Screening of Feral Pigeons (Columba livia) for Pathogens of Veterinary and Medical Importance
ABSTRACT Pathogens of veterinary and medical importance were investigated in 240 feral pigeons (Columba livia) captured in warehouses in São Paulo State, Brazil for one year. Rapid serum agglutination test (RST) was performed for the detection of antibodies against Mycoplasma synoviae, Mycoplasma gallisepticum and Salmonella Pullorum/Gallinarum. Positive sa

18. Distribution of serological screening markers at a large hematology and hemotherapy center in Minas Gerais, Southeastern Brazil
ABSTRACT OBJECTIVE: To assess the distribution of serological markers in blood donors at the blood banks of the Fundação Centro de Hematologia e Hemoterapia de Minas Gerais (Hemominas), Brazil, between January 2006 and December 2012. METHODS: This is a descriptive, retrospective study on blood donors screened using serological tests for markers of trans

19. Sensitivity and specificity of parallel or serial serological testing for detection of canine Leishmania infection
In Brazil, human and canine visceral leishmaniasis (CVL) caused byLeishmania infantum has undergone urbanisation since 1980, constituting a public health problem, and serological tests are tools of choice for identifying infected dogs. Until recently, the Brazilian zoonoses control program recommended enzyme-linked immunosorbent assays (ELISA) and indirect i

20. Health-related quality of life among blood donors with hepatitis B and hepatitis C: longitudinal study before and after diagnosis
ABSTRACT Introduction: There is evidence that patients suffering from chronic hepatic diseases, including chronic hepatitis B and chronic hepatitis C, have a reduced health-related quality of life. The aim of this study was to evaluate the impact of the notification of test results for hepatitis B and hepatitis C on the quality of life of blood donors. M

21. Development and Evaluation of an Indirect ELISA: Serological Survey to Detect Specific Antibodies to Bovine Herpesvirus 4
ABSTRACTThe aim of this work was to develop and evaluate an indirect enzyme-linked immunosorbent assay (ELISA) and made a serological screening for specific antibodies to BoHV-4. Bovine serum samples were collected from different Brazilian states and evaluated for the presence of antibodies for BoHV-4 and BoHV-1. The serological results obtained showed that

22. Presence of anti-Leishmania (Viannia) braziliensis antibodies in blood donors in the West-Central region of the State of Paraná, Brazil
ABSTRACTINTRODUCTION:Serological screening in blood banks does not include all transmittable diseases. American cutaneous leishmaniasis (ACL) has a high detection rate in the municipalities of the State of Paraná.METHODS:This study analyzed the presence of anti- Leishmania braziliensisantibodies in 176 blood donors who live in these endemic areas.

23. 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

24. Chagas disease in the State of Amazonas: history, epidemiological evolution, risks of endemicity and future perspectives
Chagas disease (CD) is a parasitic infection that originated in the Americas and is caused by Trypanosoma cruzi. In the last few years, the disease has spread to countries in North America, Asia and Europe due to the migration of Latin Americans. In the Brazilian Amazon, CD has an endemic transmission, especially in the Rio Negro region, where an occupationa
