Biofilm formation has been shown to complicate treatment, whereby the formation of biofilm is associated with higher minimum inhibitory concentration values of antibiotic. The objective of the current paper was to determine whether biofilm formation is variable among uropathogenic Antigen 43 (Ag43) is a surface-displayed autotransporter protein of Escherichia coli.By virtue of its self-association characteristics, this protein is able to mediate autoaggregation and flocculation of E. coli cells in static cultures. Additionally, surface display of Ag43 is associated with a distinct frizzy colony morphology in E. coli.Here we show that Ag43 can be expressed in a 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 × 0.4–0.7 µm (micrometer).

E coli colony morphology

See variations in colonial morphology among various species of bacteria. Bacteria grow on solid media as colonies. A colony is defined as a visible mass of microorganisms all originating from a single mother cell, therefore a colony constitutes a clone of bacteria all genetically alike. The shape of E.coli colonies in nutrient agar is circular while in blood agar is irregular. The size for this bacteria colony is around 1mm to 2mm. The size of the agar is measure by finding a single colony and diameter of the colony using ruler. To observe the edge of a colony, we need to look at the end of the bacterial colony.

Colonies differ in their shape, size, colour and texture.
