Septicemia fatal causada por Vibrio cholerae no-O1, no-O139 hemolítico en Chile: Caso clínico

Non-O1, non-O139 Vibrio cholerae bacteraemia: case report and literature review

Non-O1, non-O139 Vibrio cholerae (NOVC) are increasingly frequently observed ubiquitous microorganisms occasionally responsible for intestinal and extra-intestinal infections. Most cases involve self-limiting gastroenteritis or ear and wound infections in immunocompetent patients. Bacteraemia, which have been described in patients with predisposing factors, are rare and poorly known, both on the clinical and therapeutic aspects. We describe a case of NOVC bacteraemia and a systematic literature review in PubMed conducted up to November 2014 using a combination of the following search terms: “Vibrio cholerae non-O1” and “bacter(a)emia”. The case was a 70 year-old healthy male subject returning from Senegal and suffering from NOVC bacteraemia associated with liver abscesses. Disease evolution was favourable after 2 months’ therapy (ceftriaxone then ciprofloxacin). Three hundred and fifty cases of NOVC bacteraemia have been identified in the literature. The majority of patients were male (77 %), with a median age of 56 years and presenting with predisposing conditions (96 %), such as cirrhosis (55 %) or malignant disease (20 %). Diarrhoea was inconstant (42 %). Mortality was 33 %. The source of infection, identified in only 25 % of cases, was seafood consumption (54 %) or contaminated water (30 %). Practitioners should be aware of these infections, in order to warn patients with predisposing conditions, on the risk of ingesting raw or undercooked seafood or bathing in potentially infected waters.

Distribution of virulence genes in clinical and environmental Vibrio cholerae strains in Bangladesh

Vibrio cholerae, an environmental organism, is a facultative human pathogen. Here, we report the virulence profiles, comprising 18 genetic markers, of 102 clinical and 692 environmental V. cholerae strains isolated in Bangladesh between March 2004 and January 2006, showing the variability of virulence determinants within the context of public health.

Fatal non-O1, non-O139 Vibrio cholerae septicaemia in a patient with chronic liver disease

A 49-year-old male with underlying liver disease presented with fever and signs of sepsis. Non-O1/non-O139 Vibrio cholerae was isolated from his blood culture, which was positive for the hlyA and toxR genes. We report this fatal case of non-O1/non-O139 V. cholera sepsis and review the literature on non-O1/non-O139 V. cholerae sepsis in patients with chronic liver disease.
