Comparison of results for alternative detection methods and culture (MGIT broth or Lowenstein-Jensen slope).

a<p>Determined by McNemar's Chi-Square test using GenStat Release 14.2.</p><p>Results for all 280 lymph node samples are not broken down by lymph node type.</p

Interrelationships between Culture, IMS-PCR and IMS-MGIT PCR positive results.

<p>(A) visibly lesioned lymph nodes from reactor cattle, (B) non-visibly lesioned lymph nodes from reactor cattle, (C) visibly lesioned lymph nodes from non-reactor cattle detected at routine slaughter, and (D) all lymph node samples, irrespective of type.</p

Distribution of <i>M. bovis</i> spoligotypes isolated by culture and IMS-MGIT culture.

<p>Spoligotypes 269 (140*), 142* and 263* are thought to be spoligotypes 140, 142 and 263 with spacer 15 signal absent which have arisen due to lesser amounts of <i>M. bovis</i> DNA being present in IMS-MGIT cultures.</p

Comparison of IMS-PCR and Direct PCR results for 280 lymph node samples –74 non-visibly lesioned (NVL) and 206 visibly lesioned (VL).

a<p>Determined by McNemar's Chi-Square test using Genstat version 14.2.</p>b<p>Includes 166 VL and 74 NVL samples from TB skin test reactor animals plus 40 VL samples from non-reactor animals detected at routine slaughter.</p><p>Data represent number of samples with each combination of test results.</p
