Cluster analysis of the M. conjunctivae strains detected in this study based on the variable domain of the lppS gene. Name of sequence indicates the individual reference followed by right (OD) or left (OI) eye from which M. conjunctivae was detected. The year of sampling is shown with a black or white dot for 2013 or 2014, respectively. For comparison, sequences from isolates in other hosts are included: HRC/581 type strain, sequences obtained in sheep infections in eastern Swiss Alps (38 s and 2820 s) and Croatia (My 66 95), from a goat in Croatia (My 7/96), and from chamois in the Austrian Alps (2778 c and 2784 c). A separate clade of the ibex strains, all with a common origin, is observed in the tree.
