Aeromonas hydrophila Dans Les Eaux de Boisson a Djibouti: Germe Commensal ouAgent de Diarrhee. (Aeromonas Hydrophila in Drinking Waters in Djibouti: Commensal Germ or Diarrhoea Agent)

摘要

To investigate the bacteriological quality of drinking water used by inhabitantsof the Republic of Djibouti who were not supplied with piped running water, we analyzed 16 freshwater samples from various sources. Only 3 samples were sterile; they were taken from village pumps and from a water-truck. Eleven samples yielded colonies of Aeromonas hydrophila too numerous to be counted; they were taken from water tanks, metal barrels, or wells dug in either dry river beds or along the seashore. We speculate that this high isolation frequency of Aeromonas hydrophila in fresh water samples may be related to conditions that are exceptionally favorable for the growth of the bacterium (e.g. high temperature and elevated concentrations of certain salts and minerals in the fresh water of Djibouti). We wonder nevertheless whether the infected water supplies were a source of diarrhea for humans.
