Nocardia farcinica strain NCTC11134

Nocardia farcinica strain NCTC11134 is a Gram-positive, non-motile bacterium characterized by its filamentous cell arrangement and cocci shape. This organism is an aerobic chemoheterotroph, thriving in soil environments. It is classified as mesophilic, with an optimal growth temperature of 37°C. N. farcinica is notable for its pathogenicity in humans, with documented health effects including bacteremia, brain abscesses, severe pneumonia, and disseminated nocardiosis. The bacterium can cause localized or disseminated purulent or granulomatous lesions and has been associated with life-threatening infections, particularly affecting the central nervous system and causing spinal osteomyelitis. This strain has also been reported to affect Bos taurus, indicating its potential impact on livestock health. With a single replicon and one membrane, N. farcinica is free-living, suggesting its ecological role in nutrient cycling within soil microbiomes. Its pathogenic potential underscores the importance of understanding environmental microbes, especially those that can transition to pathogenic forms in hosts like Homo sapiens. The presence of this bacterium in soil highlights the interconnectedness of environmental health and human health, pointing to the need for vigilance in managing soil-dwelling pathogens that can lead to serious infections.
