Isolation and identification of Helicobacter pylori from drinking water in Basra governorate, Iraq.

A total of 198 samples of drinking water from 22 districts of Basra governorate were collected during the period October 2006 to July 2007.

| Sumario: | The mode of the transmission of Helicobacter pylori infection remains poorly understood. A total of 198 samples of drinking water from 22 districts of Basra governorate were collected during the period October 2006 to July 2007. The concentration of residual chlorine was measured and the numbers of total and faecal coliforms were counted. On modified Columbia urea agar, 469 bacterial cultures were obtained, of which 173 isolates were identified. Only 14 isolates were Helicobacter spp., of which 10 were H. pylori (2.0% of the total isolates). These isolates were tested for antibiotic susceptibility as well as ability to tolerate chlorine at 0.5 mg/L. To our knowledge, this is the first report of the occurrence of H. pylori in treated municipal drinking water. Le mode de transmission d'une infection à Helicobacter pylori reste mal connu. Cent quatre-vingt-dixhuit échantillons d'eau potable provenant de 22 districts du gouvernorat de Bassora ont été recueillis entre octobre 2006 et juillet 2007. La concentration de chlore résiduel a été mesurée et le nombre de coliformes totaux et fécaux ont été comptés. Sur les 469 cultures bactériennes obtenues à partir de la gélose Columbia modifiée à l'urée, 173 isolats ont été identifiés. Seuls 14 d'entre eux correspondaient à Helicobacter spp., dont 10 à H. pylori (2 % du total des isolats). La sensibilité aux antibiotiques de ces isolats a été testée, de même que leur tolérance au chlore à une concentration de 0,5 mg/l. À notre connaissance, il s'agit du premier signalement d'H. pylori dans de l'eau potable municipale traitée. |
