Escherichia coli (E. coli) ar gram-negative bacteria that can survive in an environment in the absence or in the posture of atmospheric oxygen (Facultative anaerobes) and, depending on the environment, may or may not produce thin hair-like structures (flagella or pili) that allow the bacteria to move and to attach to human cells. The bacteria commonly home ground in human and animal gastrointestinal tract, water,รข€¦..
The cell imprint is spherical, spiral and plate rod shaped ; unicellular and multicellular forms in filaments or aggregates. Oval straight or slue rods, and helical.
Reproduction is by binary fission or about throngs reproduce by Budding.
O = antigen
H = Flagella

Those to be considered here are the enteropathogenic (EPEC), enterotoxigenic
(ETEC), enteroinvasive (EIEC), enteroaggregative (EAggEC) and verocytotoxin-producing (VTEC).
Outbreaks caused
by VTEC
In contrast to infections with
EPEC, ETEC and EIEC,
human disease caused by
VTEC belonging to serogroup
O157 (VTEC O157)
has been recognized as an
emerging problem in the
UK.
VTEC O157 and strains
belonging to other serogroups
are associated with a spectrum of
disease, including mild diarrhoea,
severe bloody diarrhoea and haemolytic
uraemic syndrome, which is the close to common
cause of acute renal failure in children in the UK. The vast
majority of data on VTEC in the UK relate to serogroup
O157 because of the overlook of simple tests and laboratory
surveillance for VTEC of other serogroups. Outbreaks of
infection caused by non-O157 VTEC study not been
reported so far in the UK, save several have been investigated
in the Republic of Ireland and continental Europe.
Outbreaks of VTEC O157 infection in the UK
have been reported since 1985. Fig. 1 illustrates the
transmission routes in 137 outbreaks of...If you want to get a full essay, order it on our website: Orderessay
