Background: Salmonella enterica subsp. enterica serovar Virchow (antigenic formula 6,7,14:r:1,2 ) is a serovar of the O:7 (C1) serogroup. S. Virchow is a serovar adapted to poultry, but also isolated from foodborne outbreaks not directly traced back to chicken products. A 2010 report from Switzerland reported that S. Virchow was one of the 5 most common Salmonella serovars in Europe, with reports of 3rd-generation cephalosporin- and fluoroquinolone-resistance. Most often, S. Virchow infection causes gastrointestinal illness, but a 1984 report from Essex, England identified septicemic patients who suffered from neurological symptoms.
