“…Shigella paradysenteriae, Lavington, is a "new" serotype found in North Africa and Italy (Ewing, 1946). It is identical to cultures isolated in England by Lavington et al (1946) and by Heller and Wilson in France (1946).…”

The present communication is to report the occurrence of dysentery microorganisms in the Mediterranean area. Similar data on the Salmonella types found in that vicinity are given by Bruner and Joyce (1946). Between September, 1943, and October, 1945, more than 1,344 Shigella cultures were examined serologically 'and biochemically. These were isolated in the Section of Bacteriology of the 15th Medical General Laboratory during foodhandler examinations and in the investigation of outbreaks of bacillary dysentery or were submitted for identification from the laboratories of U. S. Army hospital units or medical laboratories. Of the 1,344 cultures, 1,182 were recovered in Italy between January, 1944, and October, 1945. Most of the remainder were isolated in North Africa (Casablanca to Bizerte) before January, 1944, although a few cultures originated in Sicily and southern France. METHODS Shigella cultures were identified tentatively by slide agglutinative tests with absorbed antiserums and confirmed by agglutination in serially diluted absorbed antiserums or by one-tube tests (Ewing, 1944). The serological methods employed were based largely on the work of Boyd (1938, 1940) but were similar to those described by other investigators (Wheeler, 1944a, 1944b; Weil et al., 1944). All cultures were confirmed as members of the genus Shigella by their bio

“…Many microorganisms were encountered that proved to be different, serologically or biochemically, from the described shigellae. Some of these were studied extensively Ewing, 1946), and others are being investigated at present. Table 1 lists all of the Shigella types encountered in the period mentioned.…”

“…The Salmonella and ShigeUa species tested in this investigation and in subsequent routine use of the medium over a period of 6 months were never found to produce even a trace reaction on the medium described. Ewing (1946) subsequently used the medium routinely in the examination of thousands of feces specimens and confirmed these findings.…”
