    Ochratoxin A significantly harmed mice by reducing red blood cells and hemoglobin. This mycotoxin also altered white blood cell counts and drastically increased clotting time.

    Area of Science:

    • Toxicology
    • Hematology
    • Mycotoxicology

    Background:

    • Ochratoxin A is a common mycotoxin found in food.
    • Mycotoxins can pose significant health risks to various organisms.
    • Understanding ochratoxin A's toxicological effects is crucial for public health.

    Purpose of the Study:

    • To investigate the hematological effects of ochratoxin A exposure in mice.
    • To determine the impact of ochratoxin A on blood clotting parameters.

    Main Methods:

    • Mice were administered ochratoxin A intraperitoneally at a dose of 5 mg/kg.
    • Blood samples were analyzed for hemoglobin, red blood cell count, and white blood cell differential counts.
    • Clotting time was measured in treated and control mice.

    Main Results:

    • Ochratoxin A significantly decreased hemoglobin levels and total red blood cell counts.
    • A notable increase in small lymphocytes and a decrease in neutrophils, basophils, and monocytes were observed in white blood cells.
    • Clotting time was prolonged more than six-fold in mice treated with ochratoxin A.

    Conclusions:

    • Ochratoxin A exerts significant hematotoxic effects in mice.
    • The mycotoxin disrupts normal blood cell profiles and impairs blood coagulation.
    • Further research is warranted to understand the mechanisms and long-term implications of ochratoxin A toxicity.
