Microbe Identification
Microbe nameBuchnera aphidicola
NCBI Taxonomy ID9
DescriptionHelicobacter pylori is a microbe that thrives in a hostile environment within the human stomach. It belongs to the temperature preference category of Thermophilic, with an optimal growth temperature range of 37°C to 40°C. Its metabolism is that of a Chemoheterotroph, meaning it derives its energy by breaking down organic compounds and using them as a source of carbon and energy. H. pylori produces energy through anaerobic respiration, a process that involves the breakdown of nutrients without the presence of oxygen. The microbe's shape is characterized by a curved or spiral shape, often referred to as a "helix," which allows it to move and colonize the surfaces of the stomach lining. Gram staining reveals that H. pylori is a Gram-negative bacteria, which is typical of many pathogenic bacteria. In terms of body sites, H. pylori is found in the stomach and small intestine of approximately 50-60% of the global population. H. pylori is an Obligate Anaerobe, meaning it is unable to survive in the presence of oxygen and requires a low-oxygen or anaerobic environment to thrive. This unique adaptation allows it to colonize the stomach, where oxygen levels are low due to the presence of thick mucus and acidic conditions. Helicobacter pylori is a significant human pathogen, causing chronic gastritis, peptic ulcers, and gastric cancer. Its ability to colonize the stomach lining and evade the host's immune system allows it to persist for decades, making treatment challenging. Despite its reputation as a disease-causing agent, H. pylori has also been linked to the development of stomach cancer, with some studies suggesting that it may play a role in reducing the risk of stomach cancer in some individuals. In addition to its notorious reputation, H. pylori has also been studied for its potential role in the evolution of the human gut microbiome. The microbe's unique adaptations to the human stomach have allowed it to thrive in an environment that is hostile to many other microorganisms, making it a fascinating subject of study for microbiologists and evolutionary biologists alike.
