Material and Methods
A total of 23 Charolaise cows (farm A) and 75 Limousine bulls and Cinisara and Modicana cows (farm B) were enrolled in this study. The blood samples were collected from all subjects at the following time points: before a cycle of intramuscular treatment with oxytetracycline dihydrate (T0), after 5–6 weeks from the treatment (T1), and every 10 weeks until seronegativisation (T2 in Farm A and T3 in Farm B). A serological test (MAT) was used for the diagnosis of leptospirosis.
Results
Two samples from farm A (2/23) and 29 samples from farm B (29/75) were positive to
Conclusion
It is important to use serological and molecular diagnostic techniques complementarily to identify infected individuals.
