Culture supernates of 16 strains of EPEC belonging to 6 different serogroups, when assayed on Chinese Hamster Ovary (CHO) cells up to 96-120 h, induced distinct morphological changes. The supernate activities were heat-labile, unrelated to heat-labile enterotoxin (LT), verotoxin (VT), or hemolysin, did not show necrosis in rabbit skin and caused no fluid(More)
Sixteen cytolethal distending toxin-producing enteropathogenic Escherichia coli (CLDT+ EPEC) strains of six different serogroups were included in this study. The strains showed varying adherence patterns on HEp-2 cells, i.e. six strains showed localized adherence (LA), five strains exhibited diffuse adherence (DA) and five strains were non-adherent.(More)
Coding for video transferring in communication networks is essential because the digital representation of image sequences requires a very large number of bits. Similarity in image sequences causes transferring whole of image data to be unnecessary. The statistical analysis of video signals indicates that there is a strong correlation between successive(More)
