Salmonella virchow: a cause of significant bloodstream invasion.

Salmonella virchow, a food poisoning strain previously only sporadically responsible for disease, has recently been isolated with increasing frequency in Scotland. The experience of infections due to this organism in 1980 in an infectious diseases unit is reported. Nine of 15 patients consecutively admitted with infection due to this organism were found to be septicaemic on blood culture thus highlighting the invasive propensity of this serotype.
