A search of the public domain (internet, patent databases, and research and development literature) suggests multiple potential uses in industrial, commercial and consumer settings (Table 2‑1).

E. aerogenes was not confirmed as the etiologic agent of infections in these animals; other pathogenic micro-organisms isolated along with E. aerogenes prevented accurate assessment of the cause of infection. 1974; Moore 1972a and 1972b; Schalk et al. 46, 3817-3822.

Although E. aerogenes is not known to form biofilms on its own, it has been isolated from biofilms generated by other micro-organisms (Sharma and Anand 2002). J. Syst. The cytokines and other mediators released during an important infection act together and have important effects on major organs (kidney, liver and lungs), heart and vasculature (Akira et al. 1991; Cosgrove et al.

Accumulation of lactic acid reduces the pH of the medium to about 4.0, due to which the colour of litmus changes from purple at a neutral pH to pink at the acidic pH. 2005; Payne 1988). 2003; Bone 1993; Sanders and Sanders, 1997). When the infection is with ESBL-producing E. aerogenes, imipenem, meropenem, doripenem or cefepime is recommended (Goethaert et al. Control. (2010). 2002). Many advocate the transfer of E. aerogenes to the Klebsiella genus and the use of Klebsiella mobilis instead of E. aerogenes (Skerman et al. 2001), E. aerogenes efficiency in circumventing the detrimental effects of antibiotics could pose a risk to both infected individuals and others who might become infected with resistant strains. 23, 454-461. : pathogens poised to flourish at the turn of the century.
