    Electron microscopy revealed abnormal Hepatitis B Dane particles with incomplete cores in renal dialysis patients and carriers. These findings offer new insights into Hepatitis B virus (HBV) morphology and its presence in various patient groups.

    Area of Science:

    • Hepatology
    • Virology
    • Electron Microscopy

    Background:

    • Hepatitis B virus (HBV) infection is a significant global health concern.
    • Dane particles are considered the infectious form of HBV.
    • Understanding HBV morphology is crucial for diagnosing and managing infection.

    Purpose of the Study:

    • To investigate the morphology of Dane particles in patients with Hepatitis B.
    • To identify any abnormalities in Dane particle structure associated with different clinical presentations of Hepatitis B.

    Main Methods:

    • Electron microscopy was utilized to examine serum samples.
    • Morphological analysis of Dane particles was performed.
    • Patient sera were screened for Hepatitis B e-antigen (HBeAg).

    Main Results:

    • Aberrant Dane particles with incomplete cores were observed.
    • These abnormal particles were abundant in a renal dialysis patient's serum.
    • Abnormal Dane particles were consistently present in sera from asymptomatic carriers, chronic hepatitis, and acute hepatitis patients.

    Conclusions:

    • The presence of incomplete cores suggests potential variations in HBV replication or assembly.
    • Abnormal Dane particle morphology may be a common feature across different stages of Hepatitis B infection.
    • Further research into these aberrant particles could reveal new diagnostic markers or therapeutic targets for Hepatitis B.
