Population-based comparative study of campylobacter and salmonella enteritis in South Australia
Abstract:
A total of 658 cases of campylobacter enteritis was reported in South Australia in the 18 months from March, 1980. Although Campylobacter sp. may cause more gastrointestinal disease than Salmonella sp. during some time periods, our data suggest that the reverse applies over all. However, since campylobacter enteritis tends to affect older persons who possibly are investigated less frequently, the relative prevalence of campylobacter infection may have been understated. Both diseases are notified among preschoolers to a disproportionate extent; however, Campylobacter sp. show a greater predisposition that Salmonella sp. for affecting teenagers and young adults. Persons with campylobacter infection are more likely to be residents of metropolitan areas than their counterparts with salmonella enteritis. Virtually all persons with campylobacter infection experience some diarrhoea; three-quarters have abdominal pain; approximately one-third report blood, and a similar proportion mucus in their stools. Children are more likely than adults to have mucus, and possibly blood, in their stools.
Insights
Campylobacter enteritis is a significant gastrointestinal illness, often underreported, particularly in older adults. This study compares its prevalence and characteristics to Salmonella enteritis in South Australia.
Area of Science:
- Infectious Diseases
- Gastroenterology
- Epidemiology
Background:
- Campylobacter enteritis and Salmonella enteritis are common causes of bacterial gastroenteritis.
- While often considered less prevalent than Salmonella, Campylobacter may cause significant gastrointestinal disease.
Purpose of the Study:
- To compare the epidemiology and clinical features of Campylobacter enteritis with Salmonella enteritis in South Australia.
- To assess the relative prevalence and demographic distribution of these two infections.
Main Methods:
- Retrospective analysis of 658 reported cases of Campylobacter enteritis in South Australia over 18 months.
- Comparison of demographic data, clinical symptoms, and geographic distribution with Salmonella enteritis cases.
Main Results:
- Campylobacter enteritis affects a broad age range, with a predilection for teenagers and young adults, and metropolitan residents.
- Diarrhea is nearly universal; abdominal pain, blood, and mucus in stools are common symptoms.
- The overall prevalence of Campylobacter infection may be understated due to under-investigation in older populations.
Conclusions:
- Campylobacter enteritis is a substantial public health concern, with distinct epidemiological patterns compared to Salmonella.
- Accurate assessment of Campylobacter prevalence requires considering age-related diagnostic biases.
- Understanding these differences is crucial for effective public health surveillance and management of bacterial gastroenteritis.
