Figure 1From: Intensive antibiotic treatment of sows with parenteral crystalline ceftiofur and tulathromycin alters the composition of the nasal microbiota of their offspringQuantitative PCR of 16S rRNA gene in nasal swabs. A 16S rRNA gene quantity (pg) detected by qPCR in nasal swabs taken from sows before (Pre-antibiotic, in yellow) and after (Post-antibiotic, in purple) first administration of their respective antibiotic treatments: crystalline ceftiofur + tulathromycin sows (CTsows) and crystalline ceftiofur sows (Csows). Each dot corresponds to one animal. B 16S rRNA gene quantity (pg) detected by qPCR in nasal swabs from piglets of the groups under study: non-treated piglets born to ceftiofur + tulathromycin treated sows (CTsowNpiglet, red); ceftiofur treated piglets born to ceftiofur + tulathromycin treated sows (CTsowCpiglet, green); non-treated piglets born to ceftiofur treated sows (CsowNpiglet, blue); and the reference group of age-matched farm piglets (grey). Each dot corresponds to one animal. Significant P values are shown in upper bars.Back to article page
