pubmed-article:7184516 | pubmed:abstractText | Sera from 108 Cricetomys gambianus (Gambia pouched rat) were investigated for HBV and HAV serum markers. 42.6% of them evidenced anti-HBs and 12.0% anti-HBc. HBs Ag was never detected. The most probable hypothesis is that these animals were infected with a new virus related to HBV. | lld:pubmed |
