Escherichia coli Infection - PubMed

3 hours ago

Escherichia coli is a gram-negative bacillus found in intestinal flora and the environment, causing diseases from mild gastroenteritis to severe complications like renal failure and septic shock.
It can evade host defenses and develop antibiotic resistance, making it a significant cause of community-acquired and healthcare-associated infections.
Infections are categorized into intestinal and extraintestinal types. Intestinal types include ETEC, EHEC/STEC, EIEC, EPEC, and EAEC; extraintestinal types involve urinary tract infections, bacteremia, pneumonia, and peritonitis.
Understanding these distinctions is crucial for accurate diagnosis, evidence-based management, and preventing complications.
