This text examines every aspect of disease association, epidemiology and identification for the enterobacteriaceae - the group of organisms responsible for more than 70 per cent of all community- and hospital-acquired infections. The first step before using any diagnostic tests is to construct an identification key or a dichotomous key by consulting different sources and finding the characteristics of the above species. Thus, we go to the index or table of contents of this manual, and finding the genera names, determine Medically important members of this family are commonly referred to as fermentative, Gram-negative, enteric bacilli , because they are Gram-negative rods that can ferment sugars .

If the result of a particular test is unavailable, select the "unknown" button. Identification of isolates All isolates were Gram-stained and tested for oxidase, catalase activity, and fermentation of glucose, by standard methods. The isolation and identification of 2,220 Enterobacteriaceae from meats indicated that Escherichia coli biotype I, Enterobacter agglomerans, and Serratia liquefaciens were the principal types to be differentiated in meats.

A summary of isolation methods for the detection and presumptive identification of important members of the Enterobacteriaceae is given in Figure 17.15. Once considered a harmless saprophyte, Serratia marcescens is now recognized as an important opportunistic pathogen combining a propensity for healthcare-associated infection and antimicrobial resistance. It is hence a well-established method for manual microorganism identification to the species level. Identification of isolates. The plasmid-mediated horizontal transmission of carbapenem-resistance genes is the main cause of the surge in the prevalence of CRE. Enterobacteriaceae Bacteria which at 30°C ± 1°C or 37°C ± 1°C are capable of forming characteristic colonies on violet red bile glucose agar (VRBGA) and that ferment glucose and show a negative oxidase reaction under the test conditions specified.
