Experimental timeline for the study.

<p>Baseline values were established from T-4 until T0 with a sampling interval of 2–3 weeks. After vaccination (T0) until the end of the experiment (T12), the sampling interval was 1 week. Animals were skin tested at T9, challenged with BCG at T9 + 3 days and euthanized at T12. T(x) = time point (week number).</p

Log transformed bacterial counts (CFU/gram) of the right prescapular lymph nodes.

<p>The data was log transformed to accommodate for the large variance. As several lymph nodes had shown no growth, equal to bacterial count = 0, +1 was added to all values to allow for log transformation.</p
