Hypothesis
What is the prevalence and antimicrobial resistance pattern of Salmonella in lactating cows and humans in dairy farms of Addis Ababa?
Conclusion
A high proportion of Salmonella isolates showed resistance to commonly prescribed antimicrobials, posing a risk for treatment of clinical cases.
Supporting Evidence
- 10.76% of lactating cows tested positive for Salmonella.
- 13.63% of humans working in dairy farms tested positive for Salmonella.
- 83.3% of Salmonella isolates showed resistance to two or more antimicrobials.
- 100% resistance to ampicillin was observed in Salmonella isolates.
Takeaway
This study found that many cows and people working with them have a type of bacteria called Salmonella, which is getting harder to treat with medicine.
Methodology
A cross-sectional study was conducted by collecting milk and faecal samples from lactating cows and stool samples from humans working in dairy farms.
Potential Biases
Potential bias in sample selection and reporting from self-reported data from human participants.
Limitations
The study was limited to a specific geographic area and may not represent other regions.
Participant Demographics
195 lactating cows and 22 humans from 23 dairy farms.
