Descriptor fimbrias bacterianas
Entry term(s) fimbrias comunes
pili bacteriano común
Scope note: Apéndices finos, semejantes a pelos, de 1 a 20 micrones de longitud y que a menudo se presentan en gran número sobre las células bacterianas gramnegativas, en particular las Enterobacteriaceas y Neisserias. A diferencia de los flagelos no poseen movilidad, pero por ser de naturaleza proteica (pilina), poseen propiedades antigénicas y hemoaglutinantes. Tienen importancia médica porque algunas fimbrias median la adherencia de las bacterias a las células mediante las adhesinas (ADHESINAS BACTERIANAS). El término fimbria bacteriana se refiere a los pelos comunes, lo que se debe distinguir del uso preferido de "pelos", que se utiliza para designar a los pelos sexuales (PILI SEXUAL).

Scope note: Thin, hairlike appendages, 1 to 20 microns in length and often occurring in large numbers, present on the cells of gram-negative bacteria, particularly Enterobacteriaceae and Neisseria. Unlike flagella, they do not possess motility, but being protein (pilin) in nature, they possess antigenic and hemagglutinating properties. They are of medical importance because some fimbriae mediate the attachment of bacteria to cells via adhesins (ADHESINS, BACTERIAL). Bacterial fimbriae refer to common pili, to be distinguished from the preferred use of "pili", which is confined to sex pili (PILI, SEX).
