| Description | Helicobacter cinaedi is a microbe that thrives in mesophilic environments, meaning it has a temperature preference category of 20-45°C. As a chemoheterotroph, it obtains its energy by breaking down organic compounds, typically in the form of carbohydrates or proteins. H. cinaedi produces energy through the process of fermentation, a metabolic pathway that converts glucose into lactic acid. Its Gram stain classification is negative, which means it does not retain the crystal violet stain used in the Gram staining technique, resulting in a pink color. The microbe has a helical shape, characteristic of the genus Helicobacter, which is typically composed of spiral-shaped bacteria. H. cinaedi can be found in a variety of body sites, including the respiratory, gastrointestinal, and genitourinary tracts, as well as skin and soft tissue. Its ability to colonize multiple sites is likely due to its ability to adapt to different environments and exploit available nutrient sources. Oxygen preference for H. cinaedi is facultative anaerobic, meaning it can grow in the presence of oxygen but can also survive and thrive in low-oxygen environments. While H. cinaedi is not typically considered a major pathogen, it can cause disease in immunocompromised individuals, such as those with HIV/AIDS or undergoing chemotherapy. In these cases, the microbe can cause a range of symptoms, from mild skin lesions to severe systemic infections. Despite its relatively innocuous nature, H. cinaedi is an important member of the human microbiome, playing a role in maintaining the balance of the intestinal ecosystem. Its ability to colonize multiple sites and adapt to changing environments makes it a resilient and fascinating microbe. |
