Evaluation of Brucella IgM and IgG ELISA Responses in Relation to Blood Culture Positivity in Pediatric Brucellosis

Background

Class-specific Brucella IgM and IgG enzyme-linked immunosorbent assay (ELISA) responses according to blood culture status are incompletely characterized in children with confirmed brucellosis. We compared IgM and IgG ELISA findings according to contemporaneous blood culture status among children already classified as having confirmed acute brucellosis; diagnostic accuracy was not assessed.
