Contribution to some phenotypical characteristics of Vibrio cincinnatiensis. Studies in one strain of a diarrhoeic human patient and in two isolates from aborted bovine fetuses.

Until now, only a few strains of V. cincinnatiensis have been isolated. This study describes a further three isolates which originated in one case from a stool specimen of an immunocompromised elder patient suffering from enteritis and in two cases from the rennin stomachs of aborted bovine fetuses. These strains grew on TCBS, CIN, MacConkey and XLD plates. Their biochemical activities were dependent on NaCl concentration, in particular the formation of indole, lysine and ornithine decarboxylases, arginine dihydrolase, the reduction of nitrate and behaviour in the Voges-Proskauer test. Moreover, lysine decarboxylase and nitrate reductase were temperature-dependent. The knowledge of these hitherto unknown phenotypical characteristics may facilitate the diagnosis of the pathogen.
