Patterns of intestinal infection in Australian Aboriginal children
Insights
Diarrhoea in Aboriginal children is frequently caused by bacterial pathogens, viruses, and parasites. Enterotoxigenic bacteria were significantly more prevalent in children with diarrhoea compared to healthy controls.
Area of Science:
- Pediatrics
- Infectious Diseases
- Microbiology
Background:
- Diarrhoea is a significant health concern in Aboriginal children.
- Understanding the aetiology of diarrhoea is crucial for effective public health interventions.
Purpose of the Study:
- To investigate the prevalence of bacterial pathogens, viruses, and parasites in Aboriginal children with diarrhoea.
- To compare the aetiological agents in children with and without diarrhoea.
Main Methods:
- A year-long, prospective study involving Aboriginal children.
- Faecal specimens were collected and analyzed for bacterial pathogens, viruses, and parasites.
- Comparison with a control group of healthy Aboriginal children.
Main Results:
- High rates of bacterial pathogens, viruses, and parasites were isolated from children with diarrhoea.
- Enterotoxigenic bacteria were found in 17% of diarrhoea cases but none of the controls.
- Bacterial pathogens (including enterotoxigenic E. coli, Aeromonas, Salmonella, Shigella, Campylobacter) were found in 39% of diarrhoea cases versus 4.5% of controls.
- Rotaviruses detected in 12% of diarrhoea cases and 8% of controls.
- Intestinal parasites, notably Giardia lamblia, affected over 25% in both groups.
Conclusions:
- Bacterial pathogens are a major cause of diarrhoea in Aboriginal children.
- Enterotoxigenic bacteria, Salmonella, and Shigella are significantly associated with diarrhoea in this population.
- While parasites are common, bacterial and viral agents play a more prominent role in symptomatic diarrhoea.
Abstract:
A year-long, prospective study of Aboriginal children with diarrhoea showed a high rate of isolation of bacterial pathogens, viruses and parasites in faecal specimens. Seventeen per cent of patients had enterotoxigenic bacteria in their stools; none of the 132 Aboriginal children without diarrhoea studied at the same time had enterotoxigenic bacteria isolated. Salmonellae and shigellae were also much more common in the diarrhoea group. Bacterial pathogens including enterotoxigenic E. coli and Aeromonas, salmonella, shigella, and campylobacter occurred in 39% of the diarrhoea group but were found in only 4.5% of the controls. Rotaviruses were detected in 12% of children with diarrhoea and in 8% of controls. Intestinal parasites, particularly Giardia lamblia, were present in over 25% of children in each group.
