[Biochemical characteristics and antigenic structures of Chlamydia]

Abstract

New biotechnology in immunology and molecular biology has enabled the identification and definition of the structure of glycolipids and especially membrane proteins of Chlamydia. Chlamydia antigen lipopolysaccharide, major outer membrane protein, protein 74 kDa, eukaryotic cell binding protein and cysteine rich proteins are all carriers of antigenic determinants, genus, species or type specific. They are very usefull for diagnosis of Chlamydial infections and epidemiological studies. These membranous antigens have an important role in the pathogenesis of these bacteries. Finally these studies have contributed to the isolation of a new species: C. pneumoniae (TWAR strains).
