Abstract. Escherichia coli is a normal inhabitant of the healthy gut, but is also an important and widespread human and animal pathogen.E. coli has been associated with human infections including diarrhea, urinary Bacterial variation in Escherichia coli book infections, and meningitis.E.

Escherichia coli is the most common gram-negative organism that causes meningitis during the neonatal period (Kim, ). In about 80% of cases, E. coli strains with the K1 capsular polysaccharides are isolated. The development of E. coli K1 meningitis is a complex and multistage process (Xie et al., ).

In addition, some strains are thought to be probiotic, and therefore beneficial to the host. However, other strains of E. coli have evolved into highly versatile, and frequently deadly, pathogens, the resultant diseases causing significant economic loss and public health burdens :// The chromosome of E.

As for many microbes, gene content across Escherichia coli strains is quite variable. The E. coli genome comprises a core set of genes shared by all E. coli isolates, and a set of flexible genes found in some but not all E. coli isolates. A commonplace assumption is that core genes share a common history of vertical :// T1 - Escherichia coli and salmonella in pigs.

Both its frequent community lifestyle and the availability of a wide array of genetic tools contributed to establish E. coli as a relevant model organism for the study of surface colonization. Several key factors, including different extracellular appendages, are implicated in E.

coli While other texts in this area deal almost solely with the "workhorse strain" Escherischia coli, Genetics of Bacterial Diversity is the first to deal with genetics and molecular biology of the wide range of other bacteria, which carry out a whole spectrum of important scientific, medical, agricultural, and biotechnological activities.
