A survey ofsera of 5,993 pregnant women for hepatitis B surface antigen in Tokyo revealed 139 asymptomatic carriers (2.3%), essentially the same as that of a control population of comparable age group (2.2%). None of 59 specimens of cord bloo d of their newborn infants was positive for HBsAg according to an immune adherence hemagglutination assay. In 11 mother-child pairs in whom follow-up was possible for more than seven months, HBsAg was detected in the sera of eight infants within the first… Expand

Hepatitis B Infection in Vanuatu: Age of Acquisition of Infection and Possible Routes of Transmission
TLDR
It is recommended that mass vaccination of all infants with hepatitis B vaccine be undertaken in hyperendemic areas. Expand
Epidemic patterns of hepatitis type B virus (HBV) and human T lymphotropic virus type I (HTLV-I) in two ATL-endemic islands in Kyushu, Japan.
TLDR
The results did not support the positive correlations between HTLV-I and HBV infections among the general population in ATL-endemic areas in Japan. Expand

Factors influencing neonatal infection by hepatitis B virus.
TLDR
It appears that the developmental period when exposure occurs, rather than the clinical status of the mother or the subtype, is the most important determinant whether the infant will be chronically infected. Expand
Hepatitis associated antigen (HAA) in pregnant women and their newborn infants.
TLDR
This investigation is based on a large-scale screening of all Danish pregnant women for HAA, and carriers of the antigen were detected and followed-up until delivery and cord blood was obtained from the newborns. Expand
Familial clustering of asymptomatic carriers of Australia antigen and patients with chronic liver disease or primary liver cancer.
TLDR
It is suggested that, in certain kindreds, Au antigen or an Au antigenrelated infective agent is transmitted from mother to child, and is also responsible for the development of the carrier state, chronic hepatitis, cirrhosis of the liver, and eventual primary liver cancer. Expand
Additional Specificities of Australia Antigen and the Possible Identification of Hepatitis Carriers
TLDR
Australia antigen, Au(1), is found transiently in the sera of many patients with acute viral hepatitis3–6 and is found in patients with some forms of leukaemia2 and Down's syndrome (who have chronic anicteric hepatitis)2,3,12,13. Expand
Detection of additional antigenic determinants of hepatitis B antigen.
TLDR
Preliminary data suggest w is more common that r on HB Ag in the United States, but r is most common in Thailand, and further study after absorbing the antisersa with heterologous antigens indicated that the reference antisera were distinguishing two additional antigenic determinants, designated w and r.

Neonatal onset of the hepatitis-associated-antigen carrier state.
HEPATITIS B antigen (HBAg) occurs in three general clinical groups: in acute B-type viral hepatitis in which HBAg is present in the early phase of illness and disappears in 95 per cent of patientsExpand
Silent Maternal Transmission of Australia Antigen
TLDR
Evidence is provided which, in combination with previous data, suggests that an important mechanism for the establishment of asymptomatic carriers of Australia antigen is through the 'silent' transmission of chronic infections from generation to generation through the maternal line. Expand
The heterogeneity of Australia antigen.
TLDR
The relationship of these Australia (Au) particles to the infective agent itself is still unresolved, but present evidence suggests that they are fragments of viral lipoprotein envelope. Expand
Haemagglutination inhibition assay of the common determinants and subspecificities of Australia antigen.
TLDR
Because it is more sensitive than conventional immunodiffusion or electrosyneresis, and more convenient than radio-immunoassay, haemagglutination inhibition is most suited to large-scale determinations of AuAg subtypes in samples of relatively low antigenic activity. Expand
