Hypothesis
What are the risk factors associated with the presence of Phage type 21/28 E. coli O157 on Scottish cattle farms?
Conclusion
PT 21/28 has significant risk factors that distinguish it from other phage types of E. coli O157.
Supporting Evidence
- PT 21/28 was present on 56.8% of E. coli O157 positive farms.
- Farms with a private water supply were significantly more likely to have PT 21/28.
- More northerly farms were more likely to be infected with PT 21/28.
Takeaway
This study found that certain farms are more likely to have a dangerous type of E. coli because of where they get their water and how many sick cows they have.
Methodology
A cross-sectional survey of 88 Scottish cattle farms was conducted to determine the prevalence of E. coli O157 and identify risk factors using generalised linear mixed models.
Limitations
The study was limited to 88 farms with E. coli O157 presence and may not represent all Scottish cattle farms.
Participant Demographics
Scottish cattle farms.
