A new Salmonella type: Salmonella seremban.

A CULTURE of a new Salmonella type of organism was received during August, 1952; it had been isolated from several patients suffering from food poisoning at Seremban, Malaya (Robinson, T. M., 1952, personal communication). On desoxycholate-citrate agar this organism produced non-lactose fermenting colonies typical of the Salmonella group. It is a Gram-negative, motile rod with the following biochemical reactions: fermentation of glucose, maltose, mannitol, dulcitol, rhamnose, trehalose and inositol with the production of acid and gas in twenty-four hours; no action on lactose, saccharose, salicin, adonitol, sorbitol and xylose. The citrate utilization test was positive; H 2S was produced but indole was not formed; gelatin was not liquefied; and urease was not produced. When examined serologically the organism was agglutinated to titre by Salmonella typhi "0" serum and reciprocal-absorption tests using this serum, Salmonella paratyphi A "0" serum, Salmonella paratyphi B "0" serum,
