Summary

Aeromonas species were found in most diarrheic children and drinking water in Cairo. Many strains, including those from tap water, produced enterotoxin, suggesting a potential public health risk.

Area of Science:

  • Microbiology
  • Public Health
  • Environmental Health

Background:

  • Aeromonas species are increasingly recognized as potential human pathogens.
  • Diarrheal diseases remain a significant public health concern, particularly in developing regions.
  • Contaminated drinking water is a common vehicle for enteric pathogens.

Purpose of the Study:

  • To investigate the prevalence of Aeromonas species in diarrheic and non-diarrheic children in Cairo, Egypt.
  • To identify potential sources of Aeromonas species, focusing on drinking water.
  • To assess the enterotoxigenicity of isolated Aeromonas strains.

Main Methods:

  • Fecal samples were collected from diarrheic and non-diarrheic children.
  • Drinking water samples were analyzed for the presence of Aeromonas species.
  • Isolates were identified to the species level.
  • Enterotoxigenicity of isolates was determined using specific assays.

Main Results:

  • Aeromonas species were detected in 88% of diarrheic children compared to 45% of non-diarrheic children.
  • Nine out of ten analyzed drinking water samples from the study area tested positive for Aeromonas species.
  • Enterotoxin production was observed in 33% of diarrheic isolates, 47% of non-diarrheic isolates, and 56% of tap water isolates.

Conclusions:

  • Drinking water in the studied Cairo district is a likely source of Aeromonas species.
  • The presence of enterotoxigenic Aeromonas in drinking water poses a potential risk to public health.
  • Further investigation into water treatment and sanitation practices is warranted to mitigate this risk.
