Description of pathotypesEscherichia coli
Escherichia coli(colitis baton) is a relatively anaerobic bacteria belonging to the familyEnterobacteriaceae. It is a symbiote forming part of the intestinal microbiome of the large intestine of warm animals, including man. In the intestine, the colon baton plays a useful role in the distribution of food. It also contributes to the production of B and K vitamins.Escherichia coliit has been shown to be pathogenic to humans and animals, mainly causing gastrointestinal and urinary disorders.
Especially serious threats to humans and animals are strains causing diarrhoea. Six patotypes stand outE. colicausing diarrhoea (DEC – Diarroeagenic)E. coli):
- ETEC
- EPEC ( Enteropathogenic strain)
- EIEC
- EAEC/EAggEC
- EHEC, VTEC
- STEC (strain producing Shiga toxin)
Escherichia coliis the most frequently identified pathogenic species transmitted by food and causing diarrhea in children. Diarrhoea remains the second most frequent cause of mortality and global morbidity. The main burden of this disease occurs in children in South Asia, Southeast Asia and Africa. Also in the case of animals, about half of the deaths of young animals are assumed to be caused by colibacterosis.
Identification of pathotype diarrhoeaE. coliis complex because pathogenic variants cannot be separated from the commensalE. colionly on a microbiological basis. It requires molecular analysis.
