Bacteria are difficult to see under the bright field microscope Bacteria are almost colorless and therefore show little contrast with the medium in which they are suspended => To visualize bacteria various dyes are used Bacteria bear a slight negative charge => bind positively charged dyes (basic stains)MORPHOLOGY OF ESCHERICHIA COLI (E COLI) Shape – Escherichia coli is a straight, rod shape (bacillus) bacterium Size – The size of Escherichia coli is about 1–3 µm × 04–07 µm (micrometer) Arrangement Of Cells – Escherichia coli is arranged singly or in pairs Motility – Escherichia coli is a motile bacterium2 Morphology and Staining of Escherichia Coli E coli is Gramnegative straight rod, 13 µ x 0407 µ, arranged singly or in pairs (Fig 281) It is motile by peritrichous flagellae, though some strains are nonmotile Spores are not formed Capsules and fimbriae are found in some strains 3 Cultural Characteristics of Escherichia Coli
