Hypothesis
What is the prevalence of Campylobacter, Salmonella, and Shigella in diarrheal infections in Central Africa from 1998 to 2022?
Conclusion
There is a significant lack of data on the prevalence of diarrheal infections caused by Campylobacter, Salmonella, and Shigella in Central Africa, highlighting the need for improved diagnostic methods.
Supporting Evidence
- Seventeen articles were selected, including 16 on humans and one on animals.
- Mono-infections with Salmonella spp. were the most predominant (55.56%).
- The most used diagnostic tool was conventional culture (82.35%).
- Data on these infections remain relatively fragmented and country-specific.
Takeaway
This study looked at how often certain germs cause diarrhea in Central Africa over 24 years, and found that not enough research has been done on this topic.
Methodology
A systematic review was conducted using the PRISMA method, analyzing studies from six databases on the prevalence of these bacteria in diarrheal infections.
Potential Biases
There is a risk of bias due to the predominance of conventional culture methods, which may underestimate the prevalence of infections.
Limitations
The study is limited by the small number of articles available and the reliance on conventional culture methods for diagnosis.
Participant Demographics
The studies included data from humans and animals across six Central African countries.
