Correlations between the detection of e antigen or antibody and electron microscopic pattern of hepatitis B surface antigen (HBsAg) associated particles in the serum of HBsAg carriers. 1977

C Trepo, and R G Bird, and A J Zuckerman

The distribution of HBsAg associated particles, especially the presence of Dane particles, was studied by electron microscopy in coded sera of 68 chronic HBsAg carriers. Results were correlated with the detection of eAg or Ab and clinical diagnosis. Sera from haemodialysis and chronic hepatitis patients showed a high prevalence of e antigenaemia (9/13, 69-2% and 8/19, 42-1%) and Dane particles (11 and 16 respectively, 84%). By contrast, out of 36 chronic asymptomatic carriers of HBsAg, 28 (77-7%) were positive for e antibody but only 1 (2-7%) had eAg. Dane particles were found in 13/36 (36-1%). A statistically significant correlation was observed between the detection of eAg and the presence of Dane particles (94-4%) in the serum. However, Dane particles were still observed in 10/28 (35-7%) of anti-e positive sera. The data suggest that eAg may be linked to complete HB virions.

UI	MeSH Term	Description	Entries
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D002353	Carrier State	The condition of harboring an infective organism without manifesting symptoms of infection. The organism must be readily transmissible to another susceptible host.

D006509	Hepatitis B	INFLAMMATION of the LIVER in humans caused by a member of the ORTHOHEPADNAVIRUS genus, HEPATITIS B VIRUS. It is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.	Hepatitis B Virus Infection

D006511	Hepatitis B Antigens	Antigens of the virion of the HEPATITIS B VIRUS or the Dane particle, its surface (HEPATITIS B SURFACE ANTIGENS), core (HEPATITIS B CORE ANTIGENS), and other associated antigens, including the HEPATITIS B E ANTIGENS.

D006514	Hepatitis B Surface Antigens	Those hepatitis B antigens found on the surface of the Dane particle and on the 20 nm spherical and tubular particles. Several subspecificities of the surface antigen are known. These were formerly called the Australia antigen.	Australia Antigen,HBsAg,Hepatitis B Surface Antigen,Antigen, Australia
