Comparison of the most abundant taxa in the study groups and healthy farms. Relative abundances (log scaled) of the top 15 most prevalent genera found in nasal cavities of piglets from the different groups of this study and in age-matched animals from farms from the studies of Correa-Fiz et al. [5, 8]. Genera have been labelled as found between the most abundant in farms, this study groups, or both. Farms are labelled withs their original ID from their respective studies. Abundances in samples from this study are shown per group: non-treated piglets born to ceftiofur + tulathromycin treated sows (CT_sowN_piglet); ceftiofur treated piglets born to ceftiofur + tulathromycin treated sows (CT_sowC_piglet); non-treated piglets born to ceftiofur treated sows (C_sowN_piglet).
