Warren and Marshall: curved bacilli on gastric epithelium

What changed

Reported curved bacteria on gastric epithelium with active chronic gastritis in the 1983 Lancet correspondence.

Scientific scope

PubMed indexes the 1983 Lancet item under Warren and Marshall without an abstract. Warren’s Nobel lecture describes his summary letter and Marshall’s accompanying letter separately; this record preserves the indexed two-name target identity and does not merge the later 100-patient 1984 paper or eradication evidence.
