Abstract
Aeromonas hydrophila is a bacteria frequently found in fresh water and saline water. Certain strains of the species have been known to cause disease in fish and amphibians for several years, although some controversy exists about its ability to cause illness in humans. Nevertheless, either through open wounds or contaminated food or water, it can give rise to infection. However, almost all articles refer to isolated cases, rather than to outbreaks.
In most cases it produces gastroenteritis in healthy people, whilst possibly causing septicemia in people with low inmmunity.In 1998, there was concern in the hotel sector due to a considerable rise in the number of cases of gastroenteritis among tourists holidaying in certain areas of the coast of the island of Tenerife.
The Public Health Services of the Canarian Community iniciated an epidemiological study in order to establish the magnitude of the problem and the associated factors.
The inicial analysis showed a large number of tourists affected but not seriously, and only in one particular area of the coast. This suggested traveller’s diarrohea probably associated with contaminated drinking water.
