Applicability of the Platelia EIA® Aspergillus test for the diagnosis of aspergilosis in penguins

Braz. j. biol; 79 (2), 2019
Abstract Even today, an effective diagnostic test for aspergillosis in penguins is unknown, being the gold standard post-mortem examinations. The fungal antigen galactomannan (GM) has been used as a biomarker of disease in humans and is detected by the Platelia Aspergillus EIA (BioRad)®, a commercial k...

Previous hepatitis E virus infection, cirrhosis and insulin resistance in patients with chronic hepatitis C

Braz. j. infect. dis; 23 (1), 2019
ABSTRACT Background: Hepatitis E virus (HEV) infection in patients with pre-existing liver disease has shown high morbidity and lethality. The consequences of HEV superinfection in patients with chronic hepatitis C virus (HCV) infection are not fully understood. This study aimed to evaluate the associat...

Influência da Hidroquinona nas respostas imune humoral e celular induzida por vacina viral com proteína recombinante (Dengue)

A fumaça do cigarro apresenta mais de 8700 substâncias identificadas, as quais já foram relacionadas com o desenvolvimento das mais variadas doenças. Dentre elas, uma substância relevante neste contexto de toxicidade do cigarro é a hidroquinona (HQ), gerada após a biotransformação do benzeno ina...

Serum regucalcin is a useful indicator of liver injury severity in patients with hepatitis B virus-related liver diseases

Braz. j. med. biol. res; 52 (10), 2019
Regucalcin is a soluble protein that is principally expressed in hepatocytes. Studies of regucalcin have mainly been conducted in animals due to a lack of commercially available kits. We aimed to develop an enzyme-linked immunosorbent assay (ELISA) to quantify serum regucalcin in patients with hepatitis ...

Development and validation of a whole-cell ELISA for serologically diagnosing Helicobacter pylori infection in Brazilian children and adults: a diagnostic accuracy study

Säo Paulo med. j; 136 (5), 2018
ABSTRACT BACKGROUND: Serological tests are practical, with low cost, but no noninvasive tests are available for diagnosing Helicobacter pylori (H. pylori) infection in Brazil. The aim here was to develop and validate enzyme-linked immunosorbent assay (ELISA) serological tests to detect anti-H. pylori i...

Validación de un ensayo inmunoenzimático tipo ELISA para cuantificar niveles de antitoxina diftérica en suero humano
Validation of an ELISA-type immune-enzymatic test to quantify levels of diphtheria antitoxin in human serum

Introducción: La difteria aún persiste en numerosos países. En Cuba, estudios realizados en diferentes grupos etarios han demostrado que existen niveles no protectores de antitoxina diftérica en la población, por lo que es necesario contar con métodos que permitan la estimación serológica de la ...
