|
cell wall is peptidoglycan.
|
Detailed explanation-1: -Chlamydiae lack detectable peptidoglycan in their cell wall even though genes that encode their peptidoglycan biosynthesis enzymes are encoded in their genomes.
Detailed explanation-2: -Secondly, Chlamydiales do not possess a peptidoglycan (PG) cell wall with a conventional structure (Fox et al., 1990; Moulder 1993; Ghuysen and Goffin 1999).
Detailed explanation-3: -Chlamydial infections are characterized by multifocality and polymorphism changes. Chlamydia causes inflammation in the adult urethra and cervix with the possibility of serious complications, and can cause perinatal infections in infants.
Detailed explanation-4: -The chlamydial cell has a Gram-negative cell wall structure consisting of an outer membrane and an inner cytoplasmic membrane. Despite being sensitive to penicillin and containing penicillin-binding proteins, chlamydiae lack measurable muramic acid, a structure found exclusively in peptidoglycan.
Detailed explanation-5: -The outer chlamydial cell wall contains several antigenic proteins, including a 40-kilodalton (kDa) major outer membrane protein (MOMP), a 60-to 62-kDa and 15-kDa, cysteine-rich proteins, a 74 kDa species-specific protein, and 31-and 18-kDa eukaryotic cell-binding proteins, which share the same primary sequence.
