[Variants for the histological demonstration of pyloric Campylobacter with optical microscopy].

It is analyzed the use of different staining and observation techniques of Pyloric Campylobacter in gastric biopsies and brushings. Toe the ones already conventional of GRAM and W-S, the following are added: W-S + A.B.; P.A.S. + W-S; W-S; W-S + H-E; PAPANICOLAOU, MASSON'S TRICHROMIC, GRAM in tissues and complements of observation with polarization phase contrast and fluorescence. The advantages and applications connected with the bacterium study (presence, morphology, identification, quantity, location) and alterations of the antral mucosa correlated to it (cellular lesions, mucino-genesis alterations, inflammatory component) of each of them are defined.
