Final answer:
The type of E. coli that causes chronic diarrhea in young children and AIDS patients is Enteropathogenic E. coli (EPEC). E. coli strains can cause varying levels of gastrointestinal illness, with ETEC causing traveler's diarrhea and EHEC being potentially life-threatening. Culturing and PCR are used for diagnosis, while prevention includes proper hygiene and cooking. The option (B) is correct.
Step-by-step explanation:
E. coli is known to be a cause of chronic diarrhea in young children and AIDS patients. While various bacteria and viruses can cause gastrointestinal illnesses, specific strains of E. coli, such as Enteropathogenic E. coli (EPEC), can lead to severe diarrhea, particularly in infants and those living in less developed countries. These strains have additional virulence factors that can cause dangerous diarrheal disease.
Diagnosis is often made through culturing and Polymerase Chain Reaction (PCR) because numerous bacteria, viruses, and parasites can cause similar symptoms. Enterotoxigenic E. coli (ETEC) causes diarrhea and is common in travelers, whereas Enterohemorrhagic E. coli (EHEC), such as the O157:H7 strain, can lead to life-threatening diseases such as hemolytic uremic syndrome.
Prevention and treatment of E. coli infections typically involve proper food handling, cooking, and hygiene practices, as well as rehydration and occasionally antibiotics, though antibiotic resistance is an ongoing concern. Therefore, option (B) is correct.
