Escherichiosis in children: causes, symptoms, diagnosis, treatment

Escherichiosis - acute infectious diseases, mainly of young children, caused by various serovars of pathogenic E. Coli with localization of the pathological process in the digestive tract, the development of infectious-toxic and diarrheal syndromes, less often with the defeat of other organs or generalization of the process up to sepsis.

ICD-10 code

• A04.0 Enteropathogenic infection caused by Escherichia coli.
• A04.1 Enterotoxigenic infection caused by Escherichia coli.
• A04.2 Enteroinvasive infection caused by Escherichia coli.
• A04.3 Enterohaemorrhagic infection caused by Escherichia coli.
• A04.4 Other intestinal infections caused by Escherichia coli.

Escherichia - mobile (have peritrichically located flagella) gram-negative rods, do not form a dispute, facultative anaerobes. Grow well on ordinary nutrient media. Morphological and cultural properties of pathogenic and non-pathogenic Escherichia are indistinguishable. Enteropathogenic strains differ from "conventional" strains only by their enzymatic properties, antigenic composition, sensitivity to bacteriophages and colicins. The degree of antagonistic activity and pathogenicity.

Depending on the presence of various pathogenicity factors (adhesiveness, colicinogenicity, invasiveness, the ability to exotoxin, etc.). Antigenic structure of all esherichia. Causing disease in humans. Conditionally divided into enteropathogenic (EPE). Enteroinvasive (EIE) and enterotoxigenic (ETE). Diseases caused by each group of Escherichia. Have significant clinical and epidemiological features, so it is advisable to consider separately enteropathogenic. Enteroinvasive and enterotoxigenic escherichiosis. There is a proposal to provide more enteroherent and enterohemorrhagic groups of Escherichia.
