Serum immunoglobulin a antibodies to glycopeptidolipid core antigen for Mycobacteroides abscessus complex lung disease
Background: Mycobacteroides abscessus complex (MABC) exhibits smooth morphotypes, expressing glycopeptidolipid (GPL), and rough morphotypes, expressing diminished GPL, on the MABC cell wall. Few reports have focused on the relationship between anti-GPL-core immunoglobulin A (IgA) antibody and colony...
