The identification of key buccal genera to distinguish the goats with SARA occurrence (SARA susceptible) or healthy (control and SARA tolerance) status. A and B The contribution of each buccal differential genus to distinguishing the LRDSS group (A) or the HRDSS group (B) from the CON group was analysed by a support vector machine (SVM). C The correlation among all differential genera based on Spearman's rank correlation coefficient analysis (correlation coefficient > 0.6 and P < 0.05). Red and azury lines indicate negative and positive correlations between genera, respectively. Node size reflects relative abundance
