ABSTRACT
In this paper seventeen Salmonella serovars are described which were identified in the period 1979 to 1981 at the Salmonella Reference Centre of Hamburg. In addition to the Supplements Nos. XXIII (1979) to XXVI (1982) further serological, biochemical and epidemiological data of each serovar are given.

In the study of a limited epidemic of Salmonella typhimurium infections, the plasmid content (pattern) of bacteria was used as an epidemiologic tool outside the hospital environment. Comparisons were made with lysotyping, resistance pattern determination (14 antibiotics), and biotyping. Plasmid pattern determination was found to be as useful and accurate as lysotyping, whereas resistance pattern determination was of more limited interest. However, in this report biotyping was of no use.

An easy, rapid and economic two-step procedure is described for the detection of Salmonella/Shigella. In the first step the susceptibility of suspected colonies for the phage O-1 of FELIX and CALLOW is tested. Positive cultures are serologically confirmed. The test is performed on Triple Sugar Iron Agar and lasts 4-6 hrs. Phage negative cultures which are lactose- and sucrose negative are tested for lysine decarboxylase and, if Shigella is possible (i.e. in human material on primary plates), for indol production and motility in a semisolid tryptophane agar. Of 22880 Salmonella straine 21977, i.e. 96.1% were phage-sensitive. Strains belonging to certain O-groups (OE) or species are lysed at a lower percentage. However, since they are lysine decarboxylase positive they are not lost and can be submitted to a serological examination.
