Fig. 1From: Use of trachea-bronchial swab qPCR testing to confirm Mycoplasma hyopneumoniae seropositivity in an SPF breeding herdTracheo-bronchial swab (TBS) sampling results of different age categories (n = 18 animals per age category) at the Central-European SPF herd. Piglets of 3–6–9-12 and 15 weeks and rearing gilt of 18–21-24 and 27 weeks of age were sampled. The qPCR M. hyopneumoniae-positive animals per age category were expressed as percentage (red line). The Ct values of those qPCR M. hyopneumoniae-positive TBS samples (Ct < 37) were expressed as means (± SEM; blue bars)Back to article page
