Bovine tuberculosis history as a risk factor for recurrence in English cattle herds experiencing a breakdown.

Key Points

• To determine the influence of prior bovine tuberculosis history on recurrence in cattle herds.
• Analyzed breakdown herds with differing histories of bovine tuberculosis (OTF-W vs OTF-S).
• Focused on interferon-gamma testing for herds with a history of OTF-W.
• Considered herd sizes and their impact on tuberculosis recurrence.
• Support for prioritizing interferon-gamma testing in OTF-W history herds.
• No benefit indicated for herds with OTF-S history.
• Large herds may also have potential benefits from testing.
