Table 2 Herd prevalence and within-herd prevalence in total and per age category detected by qPCR.

From: Prevalence of Lawsonia intracellularis in pig herds in different European countries

  1. A herd was defined as positive if genome equivalents were found in at least one sample per herd. The herd prevalence reflects the percentage of herds positive per country divided by the total number of herds sampled per country. The within-herd prevalence is the percentage of samples per herd and country with L. intracellularis detection. All measured by qPCR of 144 herds and 6450 faecal samples. The darker the field in the table, the higher the percentage of positive samples/ herds.
