Abstract

In this study the importance of species as a cause of travellers’ diarrhoea was examined using a selective medium developed by the authors. species could easily be distinguished from other enteric pathogens by the colour of the colonies obtained. Nine strains of , nine of and five of were isolated from 130 specimens, representing a surprisingly high incidence of infection compared with other pathogens isolated on SS agar and TCBS agar. Patients infected with complained of abdominal pain, as for other species, but also of vomiting, which is rather characteristic of infection. To analyse the pathogenicity of these isolates, their invasiveness was examined using Caco-2 cells. Most of the . strains invaded Caco-2 cells. Random amplified polymorphic DNA (RAPD) fingerprinting showed the same profile for two isolates from individuals travelling in the same tour group. The results show that species, especially , might cause diarrhoea, and that these species are important pathogens.
