Helicobacter pylori, previously known as Campylobacter pylori, is a gram-negative, flagellated, helical bacterium.

2023年8月8日 · H. pylori is a gram-negative, microaerophilic bacterium that can infect humans. It is often found in the stomach of affected individuals and causes inflammation and ulceration. Patients harboring the bacteria are asymptomatic with abdominal pain, nausea, vomiting, and dyspepsia developing only after gastritis and peptic ulcer disease have set in.

Helicobacter pylori, a ubiquitous, microaerophilic, spiral-shaped, Gram-negative bacterium residing in the human stomach, has profoundly impacted the landscape of gastroenterology and infectious diseases since its discovery in 1982 [1].

Helicobacter pylori (H. pylori) is a 0.5–1 µm wide, 2–4 µm long, short helical, S-shaped Gram-negative microorganism. It is mostly found in the pyloric region of the stomach and causes chronic gastric infection. It is estimated that these bacteria infect more than half of the world’s population.

H. pylori is Gram-negative, microaerophilic curved or S-shaped bacteria that are highly motile due to a unipolar bundle of sheathed flagella. The cell envelope has a characteristic Gram-negative structure, but many other components have unique features adapted to the habitat of H. pylori in the human stomach 2 .

2024年7月2日 · Helicobacter pylori (H. pylori) is a gram-negative spiral flagellate microaerophilic bacterium found in the human gastric mucosa 1. It is classified as a group I carcinogen and is considered necessary but insufficient alone to cause gastric adenocarcinoma. More often than not, it results in chronic gastritis and colonizes its host for decades.

2023年9月27日 · Helicobacter pylori (H. pylori) is a type of bacteria that infects your stomach. It can cause sores and inflammation in the lining of your stomach or the upper part of your small intestine (the...

2024年11月21日 · Helicobacter pylori is a gram-negative, spiral-shaped bacterium that is commonly found in the stomachs of humans. It is one of the most prevalent bacterial infections worldwide, with an estimated two-thirds of the global population carrying the bacterium.

H. pylori is a gram-negative organism that is highly adapted to an acid environment and often infects the stomach; incidence of infection increases with age. Infection predisposes to gastric, prepyloric, and duodenal ulcers and increases risk of gastric adenocarcinoma and lymphoma.

H. pylori is a gram-negative organism that is highly adapted to an acid environment and often infects the stomach; incidence of infection increases with age—by age 60, about 50% of people are infected.
