Haemophilus parainfluenzae strain C2011020591

Haemophilus parainfluenzae strain C2011020591 is a Gram-negative bacterium characterized by its rod shape and the presence of flagella. This organism is classified as an aerobe and facultative anaerobe, which indicates its ability to grow in both the presence and absence of oxygen. It is mesophilic, thriving within a moderate temperature range. This strain is significant in a clinical context, as it has been associated with various health conditions in humans, including bacteremia, pneumonia, endocarditis, purulent pericarditis, acute bacterial meningitis, and chancroid. The organism exhibits a free-living biotic relationship, suggesting its ability to survive independently in host-associated environments. Notably, H. parainfluenzae strain C2011020591 contains a single replicon and is composed of two membranes, a characteristic feature of Gram-negative bacteria. The strain is primarily found in association with Homo sapiens, reinforcing its relevance in human health. The ecological insight gained from the presence of H. parainfluenzae in human hosts highlights the complexities of microbial interactions within the human microbiome. Its pathogenic potential underscores the importance of understanding host-associated bacteria not only as commensals but also as opportunistic pathogens that can lead to serious health complications. The ability of H. parainfluenzae to persist in the human host environment while also being capable of causing disease exemplifies the dual nature of many microorganisms within human ecosystems.
