Humoral immune response to measles and varicella vaccination in former very low birth weight preterm infants

Braz. j. infect. dis; 22 (1), 2018
ABSTRACT Introduction: Immune response to vaccination in infants born prematurely may be lower than in infants born at full-term. Some clinical factors might be associated with humoral immune response. Objectives: The objectives of this study were to compare the immune response to measles and varicella...

Development of an indirect ELISA based on recombinant capsid protein to detect antibodies to bovine leukemia virus

Braz. j. microbiol; 49 (supl.1), 2018
Abstract Serological testing and culling infected animals are key management practices aiming eradication of bovine leukemia virus infection. Here, we report the development of an indirect ELISA based on BLV recombinant capsid protein (BLVp24r) to detect anti-BLV antibodies in cattle serum. The BLVp24r w...

First serologic evidence of human hantavirus infection in Alagoas State in Northeastern Brazil

Abstract INTRODUCTION: Hantavirus cardiopulmonary syndrome (HCPS) is rare in Northeastern Brazil. METHODS: Prospective surveillance was conducted over a two-year period in Alagoas State, Northeastern Brazil. The prevalence of anti-hantavirus N-antigen IgM and IgG in human serum samples was determined...

Development of a prototype immunochromatographic test for rapid diagnosis of respiratory adenovirus infection

Braz. j. infect. dis; 21 (5), 2017
Abstract Human adenoviruses comprise an important group of etiologic agents that are responsible for various diseases in adults and children, such as respiratory, ocular, gastroenteric, and urinary infections. In immunocompromised and organ-transplanted individuals, these agents can cause generalized inf...

Serological and molecular analysis of parvovirus B19 infection in Mayan women with systemic lupus erythematosus in Mexico

Colomb. med; 48 (3), 2017
Abstract Background: Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that mainly affects women, characterized by the production of autoantibodies. Its causal agent is unknown, but the combination of environmental, hormonal and genetic factors may favor the development of the disease...

Seropositivity diagnosis for hantavirus in Jataí, Goiás State, Brazil

Abstract INTRODUCTION: Emerging diseases are of great interest, especially those associated with high mortality rates such as hantaviruses. We aimed to conduct a seroepidemiological survey to determine the levels of hantavirus infection. METHODS: In-house enzyme-linked immunosorbent assay (ELISA) was...

Polyspecific antibodies without persisting antigen in multiple sclerosis, neurolupus and Guillain-Barré syndrome: immune network connectivity in chronic diseases

Arq. neuropsiquiatr; 75 (8), 2017
ABSTRACT The polyspecific antibody synthesis in multiple sclerosis (MS) gained diagnostic relevance with the frequent combination of measles-, rubella- and varicella zoster antibodies (MRZ-antibody reaction) but their pathophysiological role remains unknown. This review connects the data for intrathecal ...

Molecular detection of mixed infections with multiple dengue virus serotypes in suspected dengue samples in Tamaulipas, Mexico

Mem. Inst. Oswaldo Cruz; 112 (7), 2017
This study aimed to detect dengue virus (DENV) serotypes in serum samples obtained in Matamoros Tamaulipas, Mexico, and to determine the concordance of conventional nested reverse transcriptase polymerase chain reaction (RT-PCR) and a serological test [enzyme-linked immunosorbent assay (ELISA NS1)]. Here...

Neurological manifestations of dengue in Central Brazil

Abstract INTRODUCTION: The incidence of dengue has increased throughout the 2000s with a consequent global increase in atypical clinical forms. METHODS: This study reports a series of cases of neurological dengue out of 498 confirmed cases of laboratory dengue in Goiânia, Brazil. Cases were confirmed ...
