Types of E. Coli

There are several types of E. coli, some of which are beneficial for health, including preventing diseases caused by other bacteria and producing vitamin K, important for blood clotting. However, there are some that give rise to intestinal infections, which can be minor or very serious.

Type of E. Coli harmful to health

The pathogens of E. coli that cause health risks are those that cause gastroenteritis in children, being E.coli enterotossigene (ETEC), E. coli enteroinvasive (EIEC), E.coli enteropathogen (EPEC); E. coli enteroemorragico (EHEC /), E. coli enteroaggregante and E.coli extra-intestinal pathogen, which cause forms of gastroenteritis. The most serious form is entero-hemorrhagic E. coli, which produces toxins that can seriously damage the walls of the intestine, as well as the kidneys and brain. This form is potentially deadly.

Forms of E. coli contagion

In most cases, contagion occurs through ingestion of contaminated food, such as raw or undercooked beef, as well as fruits and vegetables washed with contaminated or poorly washed water. Dirty hands brought to the mouth also cause contagion.

Escherichia coli symptoms

After contact, the incubation period may vary three to four days and presenting symptoms such as urinary tract infection, watery or bloody diarrhea, gastroenteritis, vomiting, fever, septicemia and meningitis.

How to diagnose Escherichia coli

The diagnosis of E. coli is based on a clinical evaluation, on the manifestation of symptoms and by means of cytobacteriological examination urine, complete blood analysis, electrolyte level, urea and creatinine.

How to cure Escherichia coli

The choice for the ideal treatment for E. coli depends on the clinical history of the patient and symptoms presented. The main measures are to reduce dehydration. Giving antibiotics is not recommended, as it can worsen the condition.
