    Escherichia coli
    E. coli was firstly known as Bacterium coli commune as it was first isolated from the feces of newborn by Theodor Escherich. In 1935, this commensal organism caused a shocking outbreak of diarrhea affecting infants (Todar, 2008). E. coli, a versatile and highly adapted microorganism is a facultatively anaerobic Gram-negative rods that harbor the intestinal tracts of both animasl and humans and is the most important bacteria of the family Enterobacteriaceae, the enteric bacteria. E. coli has been widely attributed to cause a number of intestinal diseases. Currently, there are at least five classes (virotypes) of E. coli that are important to causing intestinal havoc. These are described briefly below (Todar, 2008).

    a. Enterotoxigenic E. coli (ETEC)
    ETEC is the widely known virotype to cause diarrhea in infants and tourists in developing countries (Clark, n.d.; Todar, 2008). The disease is characterized by a "minor discomfort to severe cholera-like syndrome" (Todar, ...
