- Multidrug-resistant (MDR) Aeromonas recovered from the metropolitan area of Valencia (Spain): diseases spectrum and prevalence in the environment. [Journal Article]
- Aeromonas infections are rare in Europe and often related to traveller's diarrhoea. A total of 185 Aeromonas isolates from river water, fish and clinical sources, recovered during a 1-year period, were used to investigate the disease spectrum and impact of multidrug-resistant (MDR) strains. They were all identified by biochemical tests and 25% of them were also identified by sequencing of the 16S…

- Travelers diarrhea affects millions of tourists each year. Most cases are caused by a variety of bacterial enteropathogens: toxigenic Escherichia coli, Campylobacter, Shigella, Salmonella, Aeromonas, Plesiomonas and non-cholera vibrios. Treatment may include antibacterial therapy with either ciprofloxacin, or azitrhomycin, or rifaximin. Viral pathogens such as norovirus usually cause short-term i…

- A severe case of Aeromonas veronii biovar sobria travellers' diarrhoea characterized by Vibrio parahaemolyticus co-isolation. [Case Reports]
- We report a severe case of travellers' diarrhoea in a patient returning from Ecuador to Italy with the concomitant presence of Aeromonas veronii biovar sobria and Vibrio parahaemolyticus in their faeces. Based on diagnostic results, epidemiological information and the clinical outcome, we conclude that the real aetiological agent was A. veronii biovar sobria, while V. parahaemolyticus was only tr…

- The mono-ADP-ribosyltransferase (mART) toxins are contributing factors to a number of human diseases, including cholera, diphtheria, traveler's diarrhea, and whooping cough. VahC is a cytotoxic, actin-targeting mART from Aeromonas hydrophila PPD134/91. This bacterium is implicated primarily in diseases among freshwater fish species but also contributes to gastrointestinal and extraintestinal infe…

- New Developments in Traveler's Diarrhea. [Journal Article]
- Traveler's diarrhea (TD) is a crucial area for research, as it affects millions of tourists each year and creates a large economic burden. More than 60% of TD cases are caused by a variety of bacterial enteropathogens: diarrhea-producing Escherichia coli, Shigella, Campylobacter, Salmonella, Aeromonas, Plesiomonas, and noncholera Vibrios. Noroviruses are also an important cause of morbidity among…

- Improvement in detection of enterotoxigenic Escherichia coli in patients with travelers' diarrhea by increasing the number of E. coli colonies tested. [Journal Article]
- No cause of one-third of travelers' diarrhea (TD) cases can be detected despite microbiologic assessment. We propose that these pathogen-negative TD cases include undetected enterotoxigenic Escherichia coli (ETEC). As a standard in diagnostic microbiology, samples of five E. coli colonies were tested to detect ETEC from stool cultures. We compared the sensitivities and the number of ETEC detected…

- [Aeromonas spp. as the causative agent of acute diarrhoea in children under 1 year of age]. [Journal Article]Epidemiol Mikrobiol Imunol. 2006 Aug; 55(3):92-8.EM
- CONCLUSIONS: Four cases of acute gastroenteritis in small children document that aeromonads are not rare and can cause serious health problems. However, epidemiological links remain unclear. We did not prove correlation between the four serious cases of acute diarrhoea and specific Aeromonas species but the results suggest the predominant role of A. caviae.
