Abstract

SUMMARY

The preliminary characterisation of an unusual gram-negative bacillus isolated from genital ulcers in Swaziland is reported. Like , it is an oxidase positive, nitrate-reductase-positive gram-negative rod that forms streptobacillary chains in some circumstances; it was therefore called the “ducreyi-like bacterium” (DLB). Distinguishing features of DLB are production of α-haemolysis on horse-blood agar, stimulation of growth by a microaerophilic atmosphere and by a factor produced by , a strongly positive porphyrin test, and a remarkable ability to undergo autolysis. DLB has a guanine + cytosine value of . 50 mole% but it cannot be classified, even at the genus level, until more taxonomic data are obtained.
