To suspect enteropathogenic escherichiosis is possible only with typical forms of the disease on the basis of gradually increasing toxicosis with excoxicosis. Severe pallor of the skin, infrequent but persistent vomiting (or regurgitation), bloating (flatulence), frequent, plentiful, watery stool with a small admixture of clear mucus, feces of yellow or orange.
The leading method of diagnosis is bacteriological. For the study take the patient's bowel movements, sometimes mucus from the oropharynx, vomit, gastric lavage, cerebrospinal fluid. Material is taken with a sterile swab from the diapers or from the pot. Sowing is produced on ordinary nutrient media (Endo, Levina, etc.). Positive results for bacteriological examination do not exceed 50-60%. The luminescent method of investigation allows obtaining an approximate result in a few hours.
Serologic methods of research in newborns and children of the first months of life, as a rule, give a negative result. RIGA in children from the second half of life is of practical importance only with the growth of the titer of specific antibodies in the dynamics of the disease.
