5. Evaluation of the diagnostic potential of CD1a immunohistochemistry for visceral leishmaniasis
ABSTRACT Visceral Leishmaniasis is a public health problem caused by protozoans of the genus Leishmania. K39 serological test is commonly used in the initial investigation, with high specificity, but variable sensitivity. Amastigotes can be identified by optical microscopy, however, the differential diagnosis with cellular debris or other intracellular paras

6. Development and standardization of a western blotting test for detection of antibodies against B. abortus
RESUMO A brucelose é uma doença infectocontagiosa, causada por bactérias do gênero Brucella spp., com diagnóstico baseado no emprego de técnicas sorológicas. Objetivou-se neste estudo desenvolver e padronizar um teste Western blotting (WB) para detecção de anticorpos contra B. abortus. Foram analisados dois grupos de amostras bovinas: grupo I, com 6

8. Validation of the Dual-path Platform chromatographic immunoassay (DPP® CVL rapid test) for the serodiagnosis of canine visceral leishmaniasis
BACKGROUND Visceral leishmaniasis is a major public health challenge in South America, and dogs are its main urban reservoir. OBJECTIVE Validation of the canine Dual-path Platform immunoassay for canine visceral leishmaniasis (DPP® CVL) for a sample set composed of 1446 dogs from different Brazilian endemic areas. METHODS A well-defined reference standard b

9. Evaluation of dot-blot test for serological diagnosis of bovine brucellosis
Abstract The objective of this study was to standardize and validate the dot-blot test for the serological diagnosis of bovine brucellosis, compare the results with those found in the 2-mercaptoethanol (2-ME) and complement fixation test (CF), and estimate the relative sensitivity and specificity of the dot-blot compared to these tests. Fifty bovine blood se

10. Serological tests fail to discriminate dogs with visceral leishmaniasis that transmit Leishmania infantum to the vector Lutzomyia longipalpis
Abstract INTRODUCTION The control of reservoirs for Leishmania infantum -induced zoonotic visceral leishmaniasis requires the identification of dogs posing a population risk. Here, we assessed the performance of several assays to identify Lutzomyia longipalpis infectious dogs. METHODS We evaluated 99 dogs that were positive for visceral leishmaniasis bas

11. 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

12. 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
