Serratia marcescens strain CHE4

Serratia marcescens strain CHE4 is a Gram-negative, rod-shaped bacterium known for its facultative anaerobic metabolism, functioning as a chemoheterotroph. This strain thrives optimally at 37°C, indicating its mesophilic nature, which aligns with the typical human body temperature, making it well-suited for colonization in human hosts. It possesses flagella, allowing for mobility, which can contribute to its pathogenicity. S. marcescens strain CHE4 is associated with various hosts, including Homo sapiens, multiple plant species (Viridiplantae), and various insects such as Apis mellifera (honeybees) and Anopheles stephensi (a malaria vector). This broad host range highlights its ecological versatility and potential for transmission across different environments. Clinically, this strain is notable for its role in nosocomial infections and conditions such as early onset neonatal sepsis and white pox disease in corals. Its ability to inhabit diverse ecological niches, combined with its pathogenic potential in humans, underscores the importance of monitoring its presence in healthcare settings and the environment. The presence of S. marcescens in both human hosts and various ecosystems reflects its adaptability and suggests a complex interplay between microbial pathogens and their environments. Understanding this strain's behavior can provide insights into infection control and the ecological impact of pathogenic microorganisms.
