d. Vibrio cholerae

검증된 단계별 안내

Step 1: Understand the question is asking for the most common bacterial cause of gastroenteritis in the United States, which is an infection of the stomach and intestines causing symptoms like diarrhea and vomiting.

Step 2: Review each option and recall their typical clinical presentations and epidemiology:

- Vibrio parahaemolyticus is associated with seafood-related gastroenteritis but is less common overall.

- Campylobacter jejuni is a leading cause of bacterial gastroenteritis worldwide and is especially common in the U.S., often linked to undercooked poultry.

- Helicobacter pylori primarily causes chronic gastritis and peptic ulcers, not acute gastroenteritis.

- Vibrio cholerae causes cholera, characterized by severe watery diarrhea, but it is rare in the U.S.

Step 3: Based on the epidemiology and clinical features, identify which bacterium is most frequently responsible for bacterial gastroenteritis in the U.S.

Bacterial Gastroenteritis

Bacterial gastroenteritis is an infection of the stomach and intestines caused by bacteria, leading to symptoms like diarrhea, vomiting, and abdominal pain. It is commonly transmitted through contaminated food or water and is a major cause of foodborne illness worldwide.

Campylobacter jejuni as a Pathogen

Campylobacter jejuni is a leading bacterial cause of gastroenteritis in the United States. It is typically acquired through undercooked poultry or contaminated water, causing symptoms such as diarrhea, fever, and cramps. It is more common than other listed bacteria in causing intestinal infections.

Distinguishing Bacterial Species in Gastrointestinal Infections

Different bacteria cause distinct gastrointestinal diseases; for example, Vibrio cholerae causes cholera with severe watery diarrhea, Helicobacter pylori is linked to stomach ulcers, and Vibrio parahaemolyticus causes seafood-related gastroenteritis. Understanding these differences helps identify the most common cause of bacterial gastroenteritis.

The most common cause of bacterial gastroenteritis in the United States is __________.a. Vibrio parahaemolyticusb. Campylobacter jejunic. Helicobacter pylorid. Vibrio cholerae
