Symptoms
Enteropathogenic escherichiosis
The incubation time for Class I EPC is several days, and the chief symptoms include vomiting, loose faeces, extreme intoxication, and dehydration. There is a chance that a generalised septic form will manifest. Adults develop class II EPKD, which manifests as salmonellosis-like symptoms.
Enteroinvasive escherichiosis
A course like dysentery or shigellosis is typical for the defeat of EIEC. The abrupt onset, one to three day incubation period, mild intoxication (headache, weakness), subfebrile to high fever levels, and chills are all symptoms. Then comes diarrhoea (occasionally with blood streaks and mucus), followed by abdominal discomfort (mostly in the area around the navel). When the belly is palpated, the colon is in discomfort. This kind of escherichiosis frequently manifests as a mild and erased form, with a modest course. The illness often lasts no more than a few days.
Enterotoxigenic escherichiosis
ETEC involvement may present with clinical symptoms similar to those of salmonellosis, food poisoning , or mild cholera . The incubation period is 1-2 days, intoxication is mild, the temperature usually does not rise, repeated vomiting is noted, profuse enteric diarrhea, dehydration gradually increases, oliguria is noted . There are pains in the epigastric region, which are cramping in nature.
This virus is sometimes referred to as "traveler's disease" since it frequently affects those who have been to tropical areas for work or pleasure. The occurrence of acute fever with chills and intoxication symptoms, as well as severe dehydration, is influenced by climatic circumstances.
Enterohemorrhagic escherichiosis
EHCP develops most often in children. At the same time, intoxication is moderate, the body temperature is subfebrile. There is nausea and vomiting , loose watery stools. In severe cases, by 3-4 days, the disease appears severe pain in the abdomen of a cramping nature, diarrhea intensifies, in stools that lose their fecal character, an admixture of blood and pus may be noted.
Most often, the disease resolves on its own after a week, but in severe cases (especially in young children) on days 7-10, after the disappearance of diarrhea, there is a chance of developing hemolytic- uremic syndrome ( a combination of hemolytic anemia, thrombocytopenia and acute renal failure ). There are frequent violations of brain regulation: cramps of the limbs, muscle rigidity, impaired consciousness up to stupor and coma . The lethality of patients with development of this symptomatology reaches 5%.
Complications
Escherichiosis is usually not prone to complications. In the case of an infection provoked by a pathogen of the EHEC group, there is a possibility of complications from the urinary system, hemolytic anemia, and cerebral disorders.
