Objective
The aim of this study was to determine the efficacy of serogroup‐specific bivalent fimbrial vaccines in the control and elimination of relatively mild (intermediate) forms of footrot in sheep flocks in NSW, there being some evidence that such forms are difficult to control.
Methods
Four flocks of sheep with history of footrot of intermediate virulence were selected based on clinical and...
Objectives
The primary objective of this study was to evaluate the clinical virulence of aprV2‐positive lesser virulent field isolates of footrot bacteria Dichelobacter nodosus in comparison with an aprV2‐positive clinically virulent reference strain. Correlations between the clinical expression of the disease and the presence of aprV2 (detected using PCR tests) have been inconsistent. A second objective...
