    Cadmium (Cd) exposure alters Euglena gracilis cell structures, particularly mitochondria and chloroplasts. These changes suggest respiratory processes are the primary target of cadmium toxicity in this organism.

    Area of Science:

    • * Cell biology
    • * Environmental toxicology
    • * Microbiology

    Background:

    • * Cadmium (Cd) is a toxic heavy metal with significant environmental and health impacts.
    • * Understanding the cellular mechanisms of Cd toxicity is crucial for risk assessment and mitigation.
    • * Euglena gracilis is a model organism for studying environmental stress responses.

    Purpose of the Study:

    • * To investigate the ultrastructural effects of cadmium exposure on Euglena gracilis.
    • * To identify the initial cellular targets of cadmium toxicity in Euglena gracilis.

    Main Methods:

    • * Culturing Euglena gracilis in the presence of cadmium.
    • * Analyzing cellular ultrastructure using electron microscopy.

    Main Results:

    • * Observed numerous myelin-like structures in mitochondria.
    • * Noted alterations in chloroplast shape and thylakoid arrangement.
    • * Detected an increase in osmiophilic plastoglobuli within chloroplasts.

    Conclusions:

    • * Cadmium exposure induces significant ultrastructural changes in Euglena gracilis.
    • * Mitochondrial and chloroplast alterations suggest a disruption of cellular energy metabolism.
    • * Respiratory processes are indicated as the initial targets of cadmium toxicity.
