Descriptor English: O Antigens
Descriptor Spanish: Antígenos O
Descriptor antígenos O
Entry term(s) antígeno O
antígeno O bacteriano
polisacáridos específicos de O
Scope note: Antígenos somáticos de lipopolisacáridos-proteínas, por lo general de bacterias gramnegativas, importantes en la clasificación serológica de los bacilos intestinales. Las cadenas específicas de O determinan la especificidad de los antígenos O de un serotipo dado. Los antígenos O son la parte inmunodominante de la molécula de lipopolisacáridos en la célula bacteriana intacta. (Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)

Scope note: The lipopolysaccharide-protein somatic antigens, usually from gram-negative bacteria, important in the serological classification of enteric bacilli. The O-specific chains determine the specificity of the O antigens of a given serotype. O antigens are the immunodominant part of the lipopolysaccharide molecule in the intact bacterial cell.
