| Description | Arcobacter butzleri is a gram-negative, spiral-shaped bacterium belonging to the temperature preference category of mesophiles, which thrive optimally at moderate temperatures. This microbe is classified as a chemoheterotroph, relying on organic compounds for both energy and carbon. It can be found in various body sites, primarily in the gastrointestinal tract of animals and humans, as well as in environmental sources such as water and soil. A notable characteristic of Arcobacter butzleri is its classification as a microaerophile, meaning it requires lower levels of oxygen for growth compared to atmospheric concentrations. As a gram-negative bacterium, Arcobacter butzleri possesses a thin peptidoglycan layer and an outer membrane rich in lipopolysaccharides, which contribute to its virulence and resistance to certain antibiotics. Its helical shape enables motility, allowing it to navigate through viscous environments like intestinal mucosa, which may help it establish infections. The bacterium's mesophilic nature indicates that it can thrive in temperatures typically found in warm-blooded hosts, creating opportunities for colonization. Arcobacter butzleri is of particular concern in food safety and public health due to its association with gastrointestinal illnesses. It is often linked to the consumption of contaminated poultry, unpasteurized milk, and seafood. Investigations into its pathogenic mechanisms are ongoing, revealing that it has the potential to cause enteritis and sepsis, particularly in immunocompromised individuals. Furthermore, its ecological versatility, outlined by its presence in various environments, underscores its ability to endure harsh conditions, enhancing its relevance in studies on microbial ecology and epidemiology. |
