Corynebacterium diphtheriae strain NCTC10838

Corynebacterium diphtheriae strain NCTC10838 is a Gram-positive, non-motile rod-shaped bacterium that serves as the etiological agent of diphtheria and can also be associated with endocarditis and systemic diseases in humans (Homo sapiens). This strain requires aerobic conditions for growth and thrives optimally at a temperature of 37°C, placing it within the mesophilic range. The bacterium possesses one membrane and one replicon, indicating a relatively simple cellular structure. It does have flagella, which is atypical for its genus, suggesting some potential for movement, although it is classified as non-motile. C. diphtheriae is known to inhabit multiple environments, which may contribute to its transmission and persistence in human populations. The health implications of C. diphtheriae underline the importance of understanding its pathogenic mechanisms, particularly in relation to diphtheria, a serious respiratory illness that can lead to severe complications. The strain's ability to cause systemic disease emphasizes its potential impact on public health. In summary, Corynebacterium diphtheriae strain NCTC10838 exemplifies a significant pathogen with distinct growth requirements and health effects. Its adaptation to multiple habitats and reliance on aerobic conditions allow it to thrive in human hosts, highlighting the need for ongoing monitoring and research on its ecological roles and health risks.
