National Reference Center for Cholera
Cholera is caused by toxin-producing Vibrio (V.) cholerae strains and manifests itself as watery diarrhea. Transmission of V. cholerae is mainly oral, through ingestion of drinking water contaminated with feces or vomit, or through food. The pathogen is widespread worldwide, but illnesses in Austria occur very rarely. In recent years, toxin-producing V. cholerae O1 strains have repeatedly been imported after stays in endemic areas; the last infection acquired in Austria was a laboratory infection.
However, non-toxin-producing V. ch olerae are repeatedly detected in Austrian waters and identified as causative agents of wound infections, gastrointestinal infections and, in rare cases, severe systemic infections.
- Differential diagnosis of Vibrio species and related genera by biochemical methods.
- Serological differential diagnosis of V. cholerae O1 and O139 and non-agglutinating Vibriones
- Detection of toxigenic V. cholerae strains by molecular biological methods
- Maintaining a strain collection of epidemiologically important human and environmental isolates
- Participation in national and international research projects on diversity and pathogenicity of cholera vibrions
- Consultation on questions of diagnostics, epidemiology, therapy, measures and prevention
Submissions should always include the origin of the isolates as well as the necessary patient, clinical and epidemiological data. Please use the corresponding submission form in the download area. Fresh cultures in transport medium (e.g. eSwab) with appropriate reference to medical-diagnostic material are best suited for sending the strains.
