An epidemic of Shigella sonnei infection is described in which the only common source of infection was the ingestion of water-melon. Bacteriological studies demonstrated that S. sonnei bacteria injected into water-melons could multiply to infective doses. Therefore water-melons should not be excluded as a possible source of S. sonnei infection.
本文描述了一起宋内志贺菌感染的疫情，此次感染唯一的共同传染源是食用西瓜。细菌学研究表明，注入西瓜中的宋内志贺菌可繁殖至感染剂量。因此，西瓜不应被排除为宋内志贺菌感染的可能来源。
