A sero-epidemiological cross-sectional study of hepatitis B virus in Zimbabwe.

Objective: To estimate the prevalence of hepatitis B viral markers.

Design: A sero-epidemiological community-based cross-sectional study.

Setting: All nine provinces of Zimbabwe.

Variant of hepatitis B virus isolated in Zimbabwe.

The polymerase chain reaction (PCR) was used to amplify an approximately 1.2 kb DNA fragment encompassing the pre-S/S gene region of HBV DNA from serum of patients with acute hepatitis B virus infection. Nucleotide sequence analysis revealed a number of interesting features in the S gene region.

The Zimbabwe National Cancer Registry began operation in 1986. Between 1986-1989, a total of 8 276 cases were identified. Among men of African descent, oesophageal (11.

Low incidence of human papillomavirus type 16 DNA in bladder tumor detected by the polymerase chain reaction.

Human papillomavirus (HPV) detection was done using the polymerase chain reaction technique on tumor tissue from 44 patients with transitional cell carcinoma of the urinary bladder. Only one of the 44 was associated with HPV infection. The HPV-positive patient was not known to have immunodeficiency or genital warts, and the tumor was not morphologically different from the other tumors.
