Sporadic Salmonella Infections: A New Salmonella Type

Abstract

1. An account is given of sporadic Salmonella infections. In the period 1929–32, thirty outbreaks occurred, involving forty-six cases, whereas, in the year 1933, thirty outbreaks involving forty-four cases were encountered.2. The investigation has shown that the most frequent cause of such infections are Salmonella types aertrycke, thompson, dublin, enteritidis and european suipestifer.3. It has been found that the dublin and suipestifer types are definitely more tissue invasive than the other types. Septicaemia and meningitis have been associated with infections due to S. dublin, and septicaemia in cases infected with S. suipestifer.4. The biochemical serological characters of a new Salmonella type—S. aberdeen—have been described.5. An infection due to S. potsdam has been encountered. This type has not been previously described as occurring in this country.
