Immunochemical differences between oral and nonoral strains of Bacteroides asaccharolyticus.

abstract：:The cytoskeletal lesions associated with enteropathogenic Escherichia coli adhering to cultured HeLa epithelial cells were examined by immunofluorescence microscopy. The microfilament-associated proteins actin, alpha-actinin, talin, and ezrin were localized with adherent enteropathogenic E. coli, whereas tropomyosin, ...
