Hypothesis
The study aimed to obtain pure cultures of spirochetes from cattle with digital dermatitis and to describe them further.
Conclusion
This study reports the isolation of a Treponema sp. from cattle with digital dermatitis in Scandinavia, which is closely related to T. phagedenis.
Supporting Evidence
- Seven spirochete isolates from five herds were obtained.
- All isolates were closely related to Treponema phagedenis.
- No antimicrobial resistance was detected among the tested isolates.
Takeaway
Researchers found a type of bacteria in cows with a foot disease, which is similar to bacteria found in cows in other countries.
Methodology
Tissue samples and swabs from active digital dermatitis lesions were cultured and analyzed using molecular typing and antimicrobial susceptibility tests.
Limitations
The study was limited to a small number of isolates from specific herds, which may not represent the broader population.
Participant Demographics
Isolates were obtained from five different herds of Swedish dairy cattle.
